Bi-directional electric motor with endplay structure

摘要

An endplay structure is provided for controlling endplay of a shaft 25 of a motor 19 . The endplay structure includes a body 22 including a generally elliptically shaped recess 26 therein. The recess is constructed and arranged to be disposed generally adjacent to an end of the shaft. An engagement member 28 has a generally spherical portion constructed and arranged to be received in a press-fit arrangement with the recess. The engagement member has a surface 32 constructed and arranged to contact the end of the shaft. Whereby, when the surface of the engagement member is contacted by the end of the shaft, the spherical portion of the engagement member is press-fitted into the recess to control endplay of the shaft.
