Rigid coupling: shrink disc Gerwah

Powerful and compact


Torque transmission is possible by means of PETER shrink-on disks.

The principle is thoroughly convincing especially in input and output connections by means of hollow shafts. Contrary to keyed connections, the non-positive connection by means of shrink-on disks permits considerably thinner wall thicknesses for the hollow shafts since the greatest part of the torque transfer is absorbed by the shrink-on disk and the shaft is not weakened by additional slots.
This results in lower shaft diameters and consequently volumetric savings in the remaining system. Weight, moments of inertia and space can be elegantly saved in this manner.

Other factors in favour of shrink-on disks are
• high performance density
• detachable connection
• rapid and simple assembly
• economic use
