Belt drives
This document discusses belt drives and the factors involved in selecting and using them. Belt drives transmit power from one shaft to another using pulleys. The amount of power transmitted depends on factors like belt velocity, tension, and arc of contact. Proper selection involves matching the drive to speeds, power needs, center distance, and service conditions. Different types of belts include flat, V, and circular belts made from materials like leather, cotton, rubber, and balata. Open, crossed, quarter-turn, idler, compound, and stepped/cone pulley drives are described.

Flywheel.ppt
The document discusses the design of flywheels. Flywheels store kinetic energy and are used to reduce power fluctuations in engines and machines. They have a heavy rotating rim connected to a central hub by several arms. Flywheels can be made of cast iron due to its ability to absorb vibrations. The stresses in flywheels include tensile stresses from centrifugal force and bending stresses from the arms resisting torque fluctuations. Proper design of the rim, arms, and materials is needed to ensure flywheels withstand the stresses during high-speed rotation.
Clutches ( Single Plate and Multi Plate)
A clutch connects and disconnects a vehicle's engine from its transmission. It allows the driver to smoothly start from a stop, change gears, and stop the vehicle while in gear. A clutch operates using friction between two surfaces - the clutch disc and pressure plate. When engaged, spring pressure holds the surfaces together to transmit torque. When disengaged by pressing the clutch pedal, the pressure is released and power is cut off. Common types are single and multi-plate clutches, with multi-plate versions able to transmit more torque due to multiple friction surfaces.
Wire rope design
The document discusses the design and selection of wire ropes, including their construction with strands of wires twisted around a core, different types of wire ropes used for various applications like mining hoists and cranes, and factors to consider like breaking strength, flexibility, and fatigue resistance. Procedures for selecting a suitable wire rope include determining the design load based on a safety factor, calculating rope diameter and wire size, and checking stresses and safety factors.
Chain drive system
Chain drive is a method of transmitting mechanical power from one place to another, often used to power vehicle wheels. It works by using a roller chain that passes over sprocket gears, with the gears' teeth meshing with the chain's links. Chains are classified into hoisting, conveyor, and power transmission chains. Power transmission chains are used in vehicles and machinery to convey power efficiently with little slippage between connected components. Chain drives require accurate installation and lubrication to function properly but can transmit power over variable distances compactly and with high efficiency.
Bearing types
Bearings support rotating shafts and allow them to rotate with minimal friction. There are two main types: plain/slider bearings where the shaft slides against the bearing, and rolling element bearings like ball or roller bearings where balls or rollers allow the shaft and bearing to roll against each other with lower friction. Rolling element bearings have lower starting torque needs and friction compared to plain bearings. Journal, footstep, and thrust bearings are types of plain bearings that support axial or radial loads on vertical or horizontal shafts. Proper lubrication is important for all bearing types to reduce friction.
1.4 law of gearing
This document discusses the law of gearing in three main points:
1) The common normal at the point of contact between gear teeth must always pass through the pitch point. This is the fundamental condition for designing gear teeth profiles.
2) The angular velocity ratio between two gears must remain constant throughout meshing.
3) The angular velocity ratio is inversely proportional to the ratio of the distances of the pitch point P from the gear centers O1 and O2. The common normal intersecting the line of centers at P divides the center distance inversely proportional to the angular velocity ratio.

Bearing
Bearings are used in machines to allow rotating parts to move freely while supporting loads. There are two main types of bearings: sliding contact/frictional bearings which operate on sliding friction; and rolling contact/anti-frictional bearings which have rolling elements like balls or rollers to reduce friction. Rolling contact bearings can carry heavier loads than sliding contact bearings and have lower friction, but are more complex and expensive to manufacture. Bearings are classified based on the type of load they support, such as radial loads, axial/thrust loads, or combined loads. Common bearing types include ball bearings, roller bearings, tapered roller bearings, and needle roller bearings.
Flywheel
A flywheel is a rotating mechanical device that stores rotational energy. It absorbs energy during periods where energy production exceeds energy demand, and releases stored energy during periods of high demand. This helps reduce fluctuations in rotational speed. Flywheels are used in engines to maintain a constant crankshaft angular velocity despite varying torque from pistons. Modern flywheels use strong, lightweight composite materials and can rotate at speeds over 100,000 rpm in a vacuum to efficiently store and deliver high amounts of energy.
Clutches for automobile
The document discusses different types of clutches used in vehicles. It describes a clutch as a mechanical device that connects and disconnects two rotating shafts to facilitate transmission of power and motion. The main types discussed are single plate clutches, multi-plate clutches, cone clutches, and centrifugal clutches. A single plate clutch uses a flywheel, pressure plate, clutch disc/plate, and release bearing. A multi-plate clutch has multiple clutch plates to transmit higher torque. A cone clutch uses a cone shape for contact rather than plates. A centrifugal clutch uses centrifugal force from rotation to engage.

spring, types, working and advantages and disadvantages.
Springs are elastic bodies that distort under load and recover their original shape when unloaded. The major types of springs are helical, conical, torsion, laminated/leaf, and disc springs. Springs work based on Hooke's law, where the force is directly proportional to displacement from the original position. Springs have advantages of being easy to manufacture, available in a wide range, and reliable with predictable performance. However, springs can buckle if deflection exceeds a critical value, and damaged springs are difficult to replace or repair.
coupling
This document discusses different types of shaft couplings, including rigid couplings like sleeve, clamp, and flange couplings as well as flexible couplings like bushed pin, universal, and Oldham couplings. It describes the purpose of couplings in connecting shafts and allowing for misalignment while transmitting motion. Requirements for good shaft couplings include easy connection/disconnection, full power transmission without losses, holding shafts in alignment, and reducing shock loads. The document concludes with information on coupling maintenance through inspection and lubrication and potential failure modes from improper installation or operation beyond design capabilities.
Hydraulic system
The document discusses hydraulic systems and their components. It begins with an introduction to hydraulic systems and then describes the main components, including reservoirs, filters, control valves, pumps, accumulators, and actuators. It explains that reservoirs store hydraulic fluid and help remove contamination with features like baffle plates and air breathers. Filters, including suction strainers and pressure line filters, work to remove particles from the fluid and protect components. Control valves direct flow and pressure. Pumps and accumulators work with valves to power hydraulic circuits. Actuators, such as cylinders and motors, provide the mechanical output of hydraulic systems.
Gear Failure
This document provides a summary of various modes of gear failure, including scoring, wear, pitting, plastic flow, and tooth breakage. It describes the causes and progression of initial, moderate, and destructive forms of each type of failure. Scoring is caused by lubrication failure and metal-to-metal contact, and can spread from initial to more widespread forms if load, speed or temperature increase. The three main types of wear are adhesive, abrasive, and corrosive. Pitting occurs due to surface fatigue and leads to the formation and spread of pits. Plastic flow and tooth breakage from bending fatigue can also cause gear tooth damage and failure over time under heavy loads.
slides on clutches
A clutch connects and disconnects two rotating shafts to engage and disengage power transmission. It consists of a driving member, driven member, and operating member. Common types include friction clutches like disc and cone clutches. A single plate clutch uses one clutch plate between a flywheel and pressure plate to transmit power from an engine to transmission. A multi-plate clutch uses multiple plates to transmit higher torque for racing cars and heavy vehicles. A cone clutch uses two conical surfaces to transmit torque through wedging action and increased surface area. A centrifugal clutch engages more at higher speeds using centrifugal force and weighted arms to connect engine and output shafts.
UNIT 2 PPT
Hydraulic actuators are used to convert hydraulic pressure into mechanical motion or force. The main types are linear actuators like hydraulic cylinders, rotary actuators like motors, and semi-rotary actuators. Hydraulic cylinders come in single-acting, double-acting, telescopic, and tandem varieties. Double-acting cylinders use hydraulic pressure on both sides of the piston to extend and retract the rod. Telescopic cylinders extend in stages for a long stroke and short retracted length. Tandem cylinders apply pressure to multiple pistons to produce increased force from a small cylinder diameter. Cushioning devices are used on cylinders to control deceleration and prevent shock at the end of the stroke.
Bearing
A bearing is a device that supports load and reduces friction between moving parts. There are two main types: plain/slider bearings and rolling/anti-friction bearings. Rolling bearings use balls or rollers to create separation between surfaces and are more commonly used. Common bearing materials include metals, alloys, and some non-metals. Bearings must be properly selected, mounted, lubricated, and maintained to maximize their lifespan and prevent premature failure.

The document discusses different types of power transmission systems including gear trains, chain drives, belt drives, and rope drives. It then focuses on belt drives, describing how the amount of power transmitted depends on factors like belt velocity, tension, and arc of contact. Belt drives are classified according to material as leather, cotton/fabric, or rubber belts. Open belt drives use parallel shafts rotating in the same direction, while crossed belt drives use parallel shafts rotating in opposite directions. Belt drives with idler pulleys are used when the angle of contact is small. Stepped or cone pulley drives change the speed of the driven shaft. Fast and loose pulley drives allow stopping the driven shaft without stopping the driver shaft. The length

Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Hematology Analyzer Machine - Complete Blood Count
The CBC machine is a common diagnostic tool used by doctors to measure a patient's red blood cell count, white blood cell count and platelet count. The machine uses a small sample of the patient's blood, which is then placed into special tubes and analyzed. The results of the analysis are then displayed on a screen for the doctor to review. The CBC machine is an important tool for diagnosing various conditions, such as anemia, infection and leukemia. It can also help to monitor a patient's response to treatment.
Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Types of Belt Drives
- 1. Design Of Machine Element (2151907) Mechanical Department Sem.: 5th D (D2) Types Of Belt Drives Prepared By: Dubey Manish S. (160123119009)
- 2. Types Of Belt Drives 1. Open belt drive. 2. Crossed or twist belt drive. 3. Quarter turn belt drive. 4. Belt drive with idler pulleys. 5. Compound belt drive. 6. Stepped or cone pulley drive. 7. Fast and loose pulley drive.
- 3. Open Belt Drive Parallel and rotating in the same direction. In this case, the driver A pulls the belt from one side (i.e. lower side RQ) and delivers it to the other side (i.e. upper side LM). Thus the tension in the lower side belt will be more than that in the upper side belt.
- 4. Crossed or twist belt drive • In this case, the driver pulls the belt from one side (i.e. RQ) and delivers it to the other side (i.e. LM). • Thus, the tension in the belt RQ will be more than that in the belt LM. The belt RQ (because of more tension) is known as tight side , whereas the belt LM (because of less tension) is known as slack side, as shown in Fig. • A little consideration will show that at a point where the belt crosses, it rubs against each other and there will be excessive wear and tear. In order to avoid this, the shafts should be placed at a maximum distance of 20 b, where b is the width of belt and the speed of the belt should be less than 15 m/s.
- 6. Quarter turn belt drive • The quarter turn belt drive (also known as right angle belt drive) as shown in Fig. (a), is used with shafts arranged at right angles and rotating in one definite direction. • In order to prevent the belt from leaving the pulley, the width of the face of the pulley should be greater or equal to 1.4 b, where b is width of belt.
- 7. Belt drive with idler pulleys • A belt drive with an idler pulley (also known as jockey pulley drive) as shown in Fig., is used with shafts arranged parallel and when an open belt drive can notbe used due to small angle of contact on the smaller pulley. • This type of drive is provided to obtain high velocity ratio and when the required belt tension can not be obtained by other means.
- 8. Compound belt drive • A compound belt drive as shown in Fig. is used when power is. transmitted from one shaft to another through a number of pulleys.
- 9. Stepped or cone pulley drive • A stepped or cone pulley drive, as shown in Fig. is used for changing the speed of the driven shaft while the main or driving shaft runs at constant speed. • This is accomplished by shifting the belt from one part of the steps to the other.
- 10. Fast and loose pulley drive • A fast and loose pulley drive, as shown in Fig. is used when the driven or machine shaft is to be started or stopped whenever desired without interfering with the driving shaft. • A pulley which is keyed to the machine shaft is called fast pulley and runs at the same speed as that of machine shaft. • A loose pulley runs freely over the machine shaft and is incapable of transmitting any power.
