Abstract
An electric motor 10 has an armature assembly 12 coupled with a rotatable shaft 16; a clamshell frame assembly 18 including first and second halves joined together, each of the first and second halves includes locking structure 32; and a pair of bearing assemblies 22 carried by the frame assembly. Each bearing assembly includes a sleeve bearing 24 and an elastomer structure 26. The elastomer structure has a main body 30 substantially surrounding the sleeve bearing, and a pair of tabs 28 extending from the main body in opposing directions. Each bearing assembly 22 is operatively associated with an end of the shaft to permit rotation of the shaft. The locking structure 32 engages the tabs 28 of an associated elastomer structure to retain the bearing assembly with respect to the frame assembly, with the elastomer structures reducing transmission of noise from the sleeve bearings to frame assembly.
