Abstract
An electric motor actuator (10) has an armature shaft (18) with a damper (28) comprising a collar (30) fit tightly into a housing (14) and slid over the shaft (18). The damper (28) has a plurality of spring-like fingers (32) protruding from the collar (30) supporting tghe shaft (18) intermediate to its journaled extreme ends (24, 26) by exerting sufficient force to damp vibrations caused by rotation of the shaft and counter-act the tendency of the shaft to move radially. The damper (28) is formed of a resilient, self-lubricating material impervious to grease, so as to isolate electrical motor parts from greased gears driven by the armature shaft.
