A presentation on spur gear
This presentation will give you an idea about spur gears and various parameters associated with it.
By Dipjyoti Deka
Gear and gear train
The document discusses gears and gear trains. It defines a gear as a toothed wheel that meshes with another gear to transmit rotation between two shafts. Gear trains involve two or more meshing gears and can be simple, compound, reverted, or epicyclic (planetary). The key advantages of gears include transmitting exact velocity ratios, transferring large power, having high efficiency, and providing reliable service in a compact layout. Potential disadvantages are the specialized tools and equipment needed for gear manufacturing and the possibility of vibrations from errors in tooth cutting.
Design and Analysis of Centrifugal Governor: A Review
This document provides a review of the design and analysis of a centrifugal governor. It begins with an abstract describing the objective to identify stress concentration areas and areas most susceptible to failure when the governor rotates. It then discusses the materials used for different governor parts, including stainless steel for the spindle and arms due to its strength. The document outlines the governor design process and criteria. It also analyzes the stresses on parts like the shaft and bearings. Graphs show how the governor's axial deflection increases with angular velocity. The analysis identifies high stress concentration areas that require strengthening to avoid failure.
Lathe-Types, Parts, Feed Mechanisms, Specifications,Lathe Accessories and Att...
Who could ever think of manufacturing metals and other materials like wood and plastic without the lathe machine? Since the lathe machine is an important tool used in the machining process, which is an integral process in the manufacturing technology, it is just fitting to learn about it.
Machining is one of the most important material removal methods in the technology of manufacturing. It is basically a collection of material working processes that involves other processes such as drilling, shaping, sawing, planning, reaming, and grinding among others. Machining is practically a part of the manufacture of all metals and other materials such as plastics, and wood as well. An important machine that is useful in machining is the lathe machine.
A lathe machine is generally used in metalworking, metal spinning, woodturning, and glassworking. The various operations that it can perform include the following: sanding, cutting, knurling, drilling, and deforming of tools that are employed in creating objects which have symmetry about the axis of rotation. Some of the most common products of the lathe machine are crankshafts, camshafts, table legs, bowls, and candlestick holders.
The first lathe machine that was ever developed was the two-person lathe machine which was designed by the Egyptians in about 1300 BC. Primarily, there are two things that are achieved in this lathe machine set-up. The first is the turning of the wood working piece manually by a rope; and the second is the cutting of shapes in the wood by the use of a sharp tool. As civilizations progressed, there have been constant modifications and improvements over the original two-person lathe machine, most importantly on the production of the rotary motion.
The production of the rotary motion therefore evolved according to the following procedures: the Egyptians manual turning by hand; the Romans addition of a turning bow; the introduction of the pedal in the Middle Ages; the use of the steam engines during the Industrial Revolution; the employment of individual electric motors in the 19th and mid 20th centuries; and the latest of which is the adaption of numerically controlled mechanisms in controlling the lathe machine.
For the lathe machine to function and perform its operations, various important parts are integrated together. These essentials parts make up the lathe machine.

Design of shafts couplings ppt
1. Shaft couplings are used to connect shafts that are manufactured separately or to introduce flexibility between shafts. The main types are rigid and flexible couplings.
2. Rigid couplings transmit torque without losses but require perfectly aligned shafts. Flexible couplings allow for misalignment. Common rigid couplings are sleeve, clamp, and flange couplings.
3. Flange couplings use separate cast iron flanges keyed to each shaft end and bolted together. The flanges and bolts are designed to transmit the torque between the shafts. Flexible couplings like bush pin couplings introduce mechanical flexibility.

The design considerations focused on using locally available materials and standard bicycle parts to create a simple and durable machine that could be manufactured and operated at low cost. The pedal-powered hacksaw has applications in furniture making industries and other workshops for basic cutting needs.
