The bond between a shaft and a hub, for a torque transmission to the rotor of a vane pump, has a driver between them with minimized axial movements for a wear-free transmission even if lateral forces are applied

摘要

The bond between a shaft (1) and a hub (3), especially for the transmission of a torque from the shaft to the hub and particularly in a vane pump, has at least one driver (2) between them Any axial movement is minimized between the contact surfaces of the shaft and the hub and/or between the shaft and the driver and/or between the driver and the hub. The end of the shaft towards the hub and the inner circumference of the hub are cambered or have two peripheral chamfers.
