Familiar and used for decades, the shrink joint is the classic connection between shaft and hub.
This way of connecting the shaft with the rotor pack is given new significance by electromobility.
Depending on the application, the “heat shrinking or “cold shrinking” variant can be advantageous when shrinking. If one variant is not sufficient for the process, both variants can also be combined. For heat shrinking, conventional furnaces or induction heating methods can be used. For cold shrinking, deep freezers or liquid nitrogen.
