Understanding Power Transmission and Drive Systems
Power transmission is the process of transferring motion and power between shafts using various mechanisms. Systems like individual drive and group drive are employed, with flexible belt drives being a common choice. Different types of belt drives, such as open belt drive, crossed belt drive, and quarter twist drive, serve specific purposes in transmitting power efficiently.

Transmission of motion and power
Power Transmission:- Power transmission is a process to transmit motion from one shaft to another shaft
Power Transmission System OR Mechanical Drive It is the intermediate mechanism which transmit power or motion from the prime mover to machine To connect the shaft ,mainly two types of connectors are used , Flexible Rigid
Individual Drive When a prime mover is used to drive a single machine then the system of power transmission is called as individual drive system
Group Drive:- main shaft Motor counter shaft Machine Machine Machine Belt
Flexible Drive:- Belt Drive:- Belts are used to transmit power between two parallel shafts by means of friction using pulleys.
Open Belt Drive:- The driver and driven shaft both rotate in the same direction in open belt drive.
Crossed belt drive: When shafts are parallel but need to be rotated in the opposite directions, crossed belt drive is used.
Quarter Twist Drive:- Belt drive 2.flv Also known as right angle belt drive, It is used to transmit power between two shafts at right angle Larger face width pulley should be used to prevent the belt from leaving the pulley
