Sliding cover for a salient-pole rotor, having a slidable support, salient-pole rotor, and electric machine

A multi-part sliding cover for a salient-pole rotor of an electric machine, wherein the sliding cover is configured to close a slot formed between two rotor poles of the salient-pole rotor which are adjacent in a circumferential direction and two axially opposite supporting rings of the salient-pole rotor, the sliding cover comprising:

• a slot closing wedge, which is mechanically connectable to the two adjacent rotor poles, and
• a support which is guided in the slot closing wedge and has a sealing surface of the sliding cover for pressing against at least one of the supporting rings and which is displaceable axially along the slot closing wedge in order to change an axial position of the sealing surface, wherein:
• the support and the slot closing wedge have mutually corresponding guide elements, which form a sliding guide for axially displacing the support with respect to the slot closing wedge,
• the support has a sealing body and a pin forming a first of the guide elements,
• the slot closing wedge has a guide channel and a guide slot forming a second of the guide elements, and
• in order to form the sliding guide, the sealing body is arranged in the guide channel and the pin is arranged in the guide slot.
