Shrink discs type HSD are detachable machine elements for the connection of a hub to a shaft. The two-part path-controlled frictional connection is maintenance-free and dirt-resistant due to its press fit and is very versatile in its use. The cost-effective and high-quality mechanical shrink discs are supplied in many different variants.
In order to ensure easy and safe assembly, the taper surfaces are lubricated.
The shrink disc is outside the flow of forces when the system is in operation. Only very rarely do low dynamic loads and no wear occur on the shrink disc. The shrink disc is therefore fatigue-proof when correctly designed.
The power transmission takes place directly from the shaft to the hub. The direct power flow ensures the highest transmittable forces and torques.
