Locking Assembly (Shrink Disc)

- заключващ монтаж is an advanced mechanical basic component that is extensively used throughout the world to ensure mechanical coupling when under heavy loads. In the coupling of the wheel and shaft, it’s a keyless coupling device that allows load transmission by tightening the tension and friction between the surfaces of the joint using high-strength bolts.

What is a Shrink Disc?

A shrink disc is a flange-shaped shaft hub with a friction lock that joins the keyless locking device, that is a new method of making a mechanical shrink fitting. It is made up of two or one thrust ring with tapered bores and an inner ring that is tapered to match.

How Does a Shrink Disc Coupling Work?

Shrink Disc, also called shrink dick coupling or locking assembly, is a kind of keyless locking device which is realized by tightening the pressure and friction force between the inclusion surface by tightening the high-strength bolts in the coupling of wheel and shaft, and is a kind of keyless coupling structure of transmission parts. Under the action of axial force, the inner jacket of the coupling assembly shrinks and rises to make the shaft and hub close together and generate enough friction to transmit torque, so as to achieve the purpose of the mechanism operation, and the keyless locking assembly itself does not transmit any torque and load.
