A tolerance ring is a component used for positioning and torque transmission in machinery.
It is primarily employed in machine tools and industrial machinery. The operating principle involves the insertion of outer or inner parts with formed wave shapes or fingers into a shaft or hole. Through rotation, these protrusions are pressed to perform positioning.
In applications, within machine tools, it is used for positioning shafts or holes in lathes and milling machines. In industrial machinery, it finds use in positioning and torque transmission in robots and press machines. Its notable features include high precision in positioning and robust torque transmission capabilities. This enables precise machine operation and efficient torque transmission. Choosing the appropriate size according to the shaft or hole and selecting suitable materials are crucial considerations.
