Coupling, rotor, and assembly for a pump

摘要

A coupling for pump, in particular a vacuum pump is provided. The coupling is configured for connecting to a rotor of the pump. The coupling includes a receiving body and at least one feed for lubricant. The receiving body includes a rotor-side end face and has a rotor-coupling region extending from the rotor-side end face. The rotor-coupling region is configured for drivingly engaging an end of the rotor. The lubricant feed is in fluid communication with the rotor-coupling region and configured for supplying the lubricant to the rotor-coupling region.

1. A coupling for a pump configured for connecting to a rotor of the pump comprising:
a receiving body including an outer circumferential surface and a flat rotor-side end face intersecting the outer circumferential surface, the receiving body having a rotor-coupling region extending from the rotor-side end face, the rotor-coupling region configured for drivingly engaging an end of the rotor; and a feed for lubricant, the lubricant feed being in fluid communication with the rotor-coupling region and configured for supplying the lubricant to the rotor-coupling region, the lubricant feed including a lubricating groove recessed into the rotor-side end face of the coupling toward the receiving body, the rotor-coupling region including a depression extending into the receiving body from the rotor-side end face, the lubricating groove extending radially from the outer circumferential surface of the receiving body to the rotor-coupling region.
