Patent ID: 7535142

Claim:
An enhanced thermal deformation resisting bearing of an electric motor, and said electric motor being comprised of a frame, a stator and a rotor installed in said frame, and said bearing comprising: an axle sleeve, disposed on said stator, and having an embedded groove extended inward and disposed at an end of said axle sleeve apart from a free end connected to said frame; a bearing, being a hollow circular body installed in said axle sleeve, and having a hollow hole groove disposed around said bearing for dividing said hollow hole groove into inner and outer layers, and a connecting portion connected between said inner and outer layers for maintaining an appropriate interval between said inner and outer layers; an axle, installed on said rotor, and sheathed into said bearing, and having a groove disposed at the periphery of said axle and corresponding to said connecting portion of said bearing; a latch, disposed at an internal side of said rotor, and protruded outward to match with an embedded groove, for latching said stator and said rotor; thereby, said embedded groove and said latch engage said stator and said rotor easily, and said groove of said axle corresponds to said connecting portion of said bearing for effectively preventing a deformation of said bearing and a shift of said axle caused by a high temperature produced by the continuous operation of said axle, so as to achieve the effects of reducing noises and enhancing the life expectancy and efficiency of said electric motor.
