GEAR TRAIN- BASIC CONCEPTS AND WORKING PRINCIPLEselvakumar948
?
The document discusses gear trains, which consist of multiple gears meshing to transmit power, reduce speed, and increase torque. It outlines various types of gear trains, including simple, compound, and epicyclic gear trains, detailing their configurations and applications. Additionally, it covers concepts like speed ratios, train values, and methods for calculating these parameters.12 rear axle casing

?
The document discusses three types of rear axle casings: 1) Split type which has two halves bolted together and requires removing the entire rear axle for repairs; 2) Banjo or separate carrier type which has a one-piece casing that carries the differential unit and allows removing half shafts for repairs; and 3) Salisbury or integral carrier type which is like the banjo type but has permanent housing tubes welded to the differential housing, making it the most widely used type today.3. v belt and sample problem

This document discusses the design and selection of V-belt drives. It describes the different types of V-belts and provides details on their cross-section. The advantages of V-belt drives are listed, such as smooth operation, ability to transmit power around corners, long service life, and acting as a safety fuse. The procedure for selecting a V-belt drive includes choosing the belt section, standard pulleys, center distance, nominal pitch length, modification factors, maximum power capacity, number of belts, and pulley dimensions. An example problem is provided to demonstrate the selection process. Key differences between flat belt drives and V-belt drives are also outlined.Bearing
BearingPOORNIMA COLLEGE OF ENGINEERING, JAIPUR
?
The document summarizes bearing design and types. It discusses how bearings support moving machine elements and allow relative motion while carrying loads. There are two main types of bearings: sliding contact bearings and rolling contact bearings. Sliding contact bearings include journal/sleeve bearings which support radial loads and come in full, partial, and fitted varieties. Rolling contact bearings use balls or rollers between elements to reduce friction. Common bearing materials include babbitt metals, bronzes, cast iron, silver, and non-metallics like carbon-graphite and rubber. Lubricants are also discussed including liquids, semisolids, and solids.Turning moment diagrams
Turning moment diagramsPOLAYYA CHINTADA
?
The document discusses turning moment diagrams, which graphically represent the turning moment or crank effort for various positions of a crank. It provides details on plotting turning moment diagrams, including representing turning moment on the vertical axis and crank angle on the horizontal axis. The document also discusses how the area of a turning moment diagram represents the work done per revolution. It further discusses turning moment diagrams for engines with multiple cylinders and how flywheels help control fluctuations in speed caused by variations in engine turning moment during each operating cycle.6 blu

?
This document discusses the basics of CNC machines including leadscrews, basic length units (BLU), and converting rotational motor motion to linear motion using pitch and teeth per inch. It provides an example of calculating pulse rate and count given a machine's BLU, feed rate, and distance to move. Open and closed loop controls are mentioned along with advantages of CNC like easier programming, storage, changes, avoiding errors, and producing complex geometries as cheaply as simple ones.Unit 7-60

?
This document discusses the design of shafts used in machines. It begins by introducing different types of shafts like stepped, cranked, and flexible shafts. It then discusses the materials used for shafts, focusing on their strength and machinability. The document provides equations to calculate shaft diameter based on the torque transmitted. It also lists permissible stress values for shaft materials under different service conditions. Finally, it discusses how shafts experience both bending and torsional stresses that must be considered in their design.Yamaji Bogd¨¢n: A j?v? atomreaktora(i)
