ABSTRACT:
An electric motor and gearbox unit, wherein the gearbox comprises a casing having an integral bearing support for the motor shaft and an epicyclic gear train within the casing, the output shaft of the gearbox being precisely aligned with the motor shaft. The gearbox can be symmetrically designed with respect to the motor axis so that a fan mounted on the motor shaft can create a symmetrical flow of cooling air over the gearbox casing and into the motor. Preferably, the epicyclic gear train comprises a sun gear on the motor shaft, a ring gear integral with the gearbox casing, and a plurality of planet gears that mesh with the sun gear and the ring gear and which are each mounted for rotation with respect to a planet carrier connected to the output shaft of the gearbox. The planet carrier has to be provided with a number of holes, one being a central hole for receiving the output shaft of the gearbox and the others being for receiving stub axles for mounting the planet gears. One or more components of the gearbox, e.g. the sun gear and/or planet carrier, are formed from two or more stamped laminations which are secured together by being progressively stacked and part sheared.
