STARTER COMPRISING ARMATURE SHAFT SET IN BEARING PLACED BETWEEN ARMATURE AND REDUCTION GEAR Russian patent published in 2013 - IPC F02N15/04 

FIELD: machine building.

SUBSTANCE: proposed starter (10) of a vehicle comprises an electric motor (16) with the rear shaft of its armature being fitted with armature windings (22), the said armature rear shaft (18) is mounted so that to rotate in the front and rear bearings (68, 32). The starter comprises also an output front shaft (20) with an actuator (64) mounted on it. The output front shaft (20) is set coaxially to the armature rear shaft (18) and is actuated by the latter with the help of planetary reduction gear (44) which is set between the armature rear shaft (18) and the output front shaft (20) to provide for their coupling. According to the present invention the second front bearing (68) is placed in axial direction between the armature windings (22) and the planetary reduction gear (44) with the satellite gears (46) of the latter being mounted on the output shaft (20) so that to rotate between two radial disks - the front one (50) and the rear one (52) - the disks are kept at a distance from each other in axial direction by at least one spacer bar (48) in order to prevent seizure of the satellite gears (46) when the front bearing (68) seats in axial direction on the rear disk (52).

EFFECT: improving reliability and enhancing service life of starter by reducing wear of bearings and shaft due to distributed forces.
