Motor mounting bearing structure

摘要

A motor mounting assembly employs a shaft 1 rotatably supported by a bearing 2 composed of a disc-like flange member 2A with through holes 2B or notches (Fig. 4). A bottom surface 2D of the flange member 2A serves for mounting a device. A housing 5 surrounds the shaft 1 and the bearing 2 with a top surface (2E, Fig. 2), of the flange member 2A being secured to the housing 5. The housing 6, has reinforced projections 6B with screw holes 6A which align with the through holes 2B in the flange member 2A and can receive screws used to fasten the device to the flange member 2A. The bearing may be an oil impregnated metal powder sintered bearing.
