A motor and transmission frame module defined by plates that are at least in part similar to one another and are fastened rigidly together in engagement over a substantial area thereof by any of a variety of securing means. Two cut out portions in the plates provide receiving means for a motor assembly and transmission gearing, respectively, with bearing receiving means being provided in the plates by aligned semispherical struck out portions that provide radial and axial support for the various bearings and permit alignment of the same upon assembly. Alternatively, struck out portions may be cylindrical to receive stub shafts of bearing blocks or the like. The plates are stiffened by ribs or flanges. The assembled plates mounting a motor and transmission are adapted to be received in a cast housing of a power unit and/or a power tool. |
