The document describes a planetary gear system designed by a team for a BAJA vehicle competition. The goal was to design a lighter, more compact gearbox with a more efficient gear ratio reduction than the one currently used. While the design achieved the transmission modes and torque requirements, it did not meet the desired 7:1 gear ratio within the required volume or weight limits. Stress analysis was performed but redesigning the vehicle frame would be needed to implement the new gearbox. The team concluded that a planetary gear system was not the best solution given the constraints.

Remanufactured engines
Remanufacturing is a process in which components of the engine is taken apart and then according to their condition cleaned, repaired and then reassembled, sometimes defective component replace by the new one. The process of remanufacturing engines is practically good and also good for economic value. In the term of engine remanufacturing, we can save energy, material, and environment. A properly remanufactured engine might be good as a new or better than the original product. It gives you over 100000 miles of support, if you maintain the engine very well then it will help to keep that mileage up as well.

Design of two stage planetary gear train for high reduction ratio
Abstract Planetary Gear Trains are extensively used for the power transmission and are the most critical component. Planetary gearboxes are used frequently to match the inertias, lower the motor speed, boost the torque, and at the same time provide a sturdy mechanical interface for pulleys, cams, drums and other mechanical components. This paper presents the advantages of planetary gear systems over other, consideration to be given while determining the reduction ratios of gear box, minimum and maximum reductions per stage of planetary gear pairs. Also the case study to determine the reduction ratio of two stage gear box is discussed. The comparison of planetary gear system over helical gears systems is done on the basis of volume, weight and torque density Keywords: Planetary Gears, Gear train, IS 4460, Torque density.

A presentation On Epicycle Gear Train
This presentation discusses epicyclic gear trains and their applications. It begins by defining an epicyclic gear train as one where the axes of gears can move relative to a fixed axis. Examples of applications include differentials in automobiles and lathes. It then discusses methods to calculate velocity ratios in epicyclic gear trains using tabular and algebraic methods. Compound epicyclic gear trains using sun and planet gears are described. Epicyclic gear trains using bevel gears are also discussed, along with examples of their use in speed reduction gears and differentials. Finally, the presentation covers torques in epicyclic gear trains and how input, output, and holding torques are related.
Epicyclic gear train
An epicyclic or planetary gear system consists of one or more planet gears that revolve around a central sun gear. The planet gears are mounted on a carrier that can also rotate relative to the sun gear. An outer ring gear meshes with the planet gears. Epicyclic gearing allows for large gear ratios in a small space through the planetary motion of gears revolving and rotating simultaneously. Applications include marine gearboxes, electric screwdrivers, lathe back gears, hoists, pulley blocks, wristwatches, bicycle transmissions, and automobile transmissions.

IRJET- Speed Variation using Cone Ring Traction Drive
This document summarizes a research paper on a cone ring traction drive continuously variable transmission (CVT). The CVT uses an input cone, output cone, and transfer ring to provide an infinite number of gear ratios between maximum and minimum values. It maintains a constant angular velocity for improved fuel efficiency compared to other mechanical transmissions with discrete gear ratios. The CVT concept described uses only mechanical components like rollers, clamping, and adjustment units to change gear ratios quickly without hydraulic delays. A mechanical torque sensor applies axial pressure proportional to output torque. This allows high transmission efficiency at light loads without costly electronic controls.

It summarizes their redesign of the engine starter to reliably start the engine, improvements to the pneumatic shifting system to shift more consistently, and a redesign of the drivetrain to use parallel chains instead of a belt and chain for better reliability and alignment. Finite element analysis and testing was performed on components to optimize design and performance.
STUDY AND ANALYSIS OF DIFFERENTIAL CONTROLLED CONTINUOUSLY VARIABLE DRIVE
Now a day's development trends in car industry and mobile machines are driven by universal concerns on energy limitations and greenhouse gases reduction, more energy efficient and environmentally friendly vehicles will be needed. As the increasing concerns in the impact of vehicle emissions of carbon dioxides and Nitrogen oxides on the biosphere combined with today's shortage fuel, hence need to find alternate fuel solutions or develop the transmission system in such a way that lower consumption and lower emission should takes place. Continuously variable drive is the type of automatic transmission that allows selection of infinite number of transmission ratios within the finite range i.e. between minimum and maximum value. Continuously variable drive is 34.91% more efficient than that of manual transmission. In order to achieve emission reduction and fuel economy needs to improve fuel efficiency. Continuously variable drive can be improved by coupling differential gear assembly to one of variable speed drives; we can increase the speed variation range at the expense of the horse power range. Numerous combinations of the variables are possible.

Creative journal
The document summarizes the design of a gearbox to lift an 8kg weight 0.5 meters using a small motor. It discusses:
- Calculating a torque ratio of 50:1 is needed between the motor and gearbox to lift the weight. They chose a ratio of 60:1 for safety.
- Considering three gearbox designs: planetary, grinder, and fixed axis spur gears.
- They selected fixed axis spur gears as the simplest design that can complete the task effectively in their two attempts, despite other options supporting load more efficiently but with more complexity.
NMSU_Design_Report_2016
This document summarizes the design of the driveline and suspension systems for New Mexico State University's 2016 Baja SAE vehicle. The driveline goals were to minimize weight and reduce the time to travel 150 feet, while withstanding cyclic loading. Analysis determined an optimal gear ratio range of 9.85-10, and a Dana H12 transmission with 10.15 ratio was selected. Components were integrated considering weight, cost, and interactions. The suspension goals were low stiffness at ride height and ability to shift weight over obstacles, while being lightweight and robust. Modal and frequency analysis informed the design.

Capstone Project
This document summarizes the design of a universal robotic drive base intended for use in FIRST robotics competitions. The drive base uses an 8 wheel "tank" drive configuration for stability. It has a lightweight aluminum frame designed through finite element analysis to withstand collisions. A custom ball shift transmission was designed to provide shift-on-the-fly capabilities between a high-speed and low-speed gear ratio. Traction tests were conducted to select effective wheels. The completed drive base weighed 38 pounds and could shift gears while moving, improving the robot's top speed and pushing force over previous designs.
SAE Brake Colloquium - Max Radial Downsize Package Wheel Bearing
The document discusses a maximum radial downsized (MRD) wheel bearing concept for light trucks and cars.
1) The MRD concept moves the wheel hub's torque transfer interface outside of the hub to reduce mass by 18% and packaging size by up to 22% compared to standard bearings.
2) Testing showed the MRD concept reduced drag torque by 34%, addressing industry needs for improved fuel economy.
3) As OEMs work to meet future efficiency regulations, the auto industry must explore lightweight technologies like the MRD bearing to reduce fuel costs and emissions.
CVT Final Presentation.RevC
The team created theoretical models of the continuously variable transmission (CVT) on the Cal Poly Baja car to improve performance. Their Adams model showed that increasing weight on the primary pulley results in faster expansion and quicker response time. Their Simulink model calculated that using the ideal CVT ratio would reduce the 0-100 ft time to under 5 seconds, improving their acceleration time by over 10%. Testing different ramp angles on the primary pulley also showed potential for obtaining the ideal ratio. Experimental validation was recommended over relying solely on analytical models.
DESIGN AND FABRICATION OF SINGLE REDUCTION GEARBOX WITH INBOARD BRAKING
An inboard braking system is an automobile technology where in the disc brakes are mounted on the chassis or to the gearbox of the vehicle, rather than directly on the wheel hubs.
The main advantages are a reduction in the unsprung weight of the wheel hubs, as this no longer includes the brake discs and calipers; also, braking torque applies directly to the chassis or the gear box , rather than being taken through the suspension arms.
Inboard brakes are fitted to a driven axle of the car, as they require a drive shaft to link the wheel to the brake. Most have thus been used for rear-wheel drive cars, although four-wheel drive and some front-wheel drives have also used them.

Creative Journal
The document summarizes a student group's project to design a gear mechanism to lift a mass of 8kg. The group's goals are to successfully lift the mass and then improve the design to lift the mass more quickly or a larger mass. The group discussed their aims and methods, and will divide tasks. Their design process will involve calculations to determine the motor torque, required lifting torque, optimal gear arrangement, velocities and lifting time. They considered spur, planetary, bevel and helical gears and chose spur gears. Their design will need adjustments for the string wrapping the shaft and CNC machine tolerances.
