working principle of rubber bellow

rubber bellow are used to transmit motion and rotational power, 

or torque, between two shafts that are offset at an angle.

Most rubber bellow consist of two yokes and a middle assembly; 

The hub end of each yoke attaches to a shaft while the yoke ears attach to 

and pivot around the middle assembly to accommodate shaft misalignment. 

The type of middle assembly determines its usage—pin 

and block joints are suitable for transmitting high torque, 

needle bearing joints are used to handle high rotational speeds and ball

socket joints are used in applications requiring low backlash (play between moving parts). 

The body of rubber bellow may include a single joint 

to accommodate only angular misalignment between shafts, 

or two joints to accommodate both angular and parallel misalignment.


Available in a variety of materials and configurations, 

rubber bellows are use din applications including motor vehicles, conveyors, medical 

and optical devices, forestry and mining equipment, robotics

 and space exploration, and aeronautics, among others
