ELECTRIC MACHINE WITH AXIAL SPRING-CONTROLLED ELEMENT Russian patent published in 2009 - IPC H02K5/173 H02K5/16 

FIELD: electric engineering.

SUBSTANCE: invention relates to electric engineering, and particularly, to electric machines and deals with their specific design being provided axial spring-controlled element. The said element is installed between rotor part on rotor shaft and antifriction bearing. Mainly, electric machine (10) is intended for bringing functional elements into operation in motor car. The said electric machine contains rotor with shaft (12) being installed in case-shaped part (16) so that it can rotate in antifriction bearing (22, 20). There is axial spring-controlled element (32) between antifriction bearing and rotor part, which is fixed to rotor shaft (12). The spring-controlled element is provided with inner (40) and outer (42) rings interconnected so that they can spring in axial direction. Outer ring (42) of axial spring-controlled element (32) is connected with rotor part (34).

EFFECT: improved reliability of electric machine by secure spring-controlled element fixing to rotor part, easy single-action assembling by providing possibility of spring-controlled element installation on rotor shaft together with rotor part, avoiding thereby clamping ring distortion during installation on shaft and mutual engagement of spring-controlled elements during transportation.
