Coaxial engine starter

Abstract

Abstract A coaxial engine starter comprises an electric motor including a yoke, an armature and a hollow armature shaft, an output shaft arranged coaxially with the armature shaft, a planet reduction gear mechanism disposed between the armature shaft and the output shaft for reducing a rotational speed of the armature shaft and rotating the output shaft at a reduced rotational speed, an electromagnetic switch having a plunger ganged with a rod for selectively coupling the output shaft to the planet reduction gear mechanism, a front bracket including an internal gear of the planet reduction gear mechanism and a bearing receiving a radial load and bolt means for securing the front bracket, the electromagnetic switch and the yoke of the motor to an engine bracket, all together. The bolt means pass axially inside said yoke and outside said internal gear and a resilient member is disposed between the front bracket and the engine bracket to absorb undesired vibration and/or shock on the engine side and to provide a higher freedom of engine layout.
