Abstract
The starting device for an internal combustion engine includes a housing, an electrical drive motor (10) with a drive shaft (16), a starting pinion (12) for engagement with a rim gear of the engine and an intermediate gear (11) making an operative connection between the drive shaft and the starting pinion. For damping or absorption of the shocks and preventing fractures arising from the compression stroke of the starting engine the starting pinion (12) is connected directly or indirectly nonrotatably with the gear shaft (24) of the intermediate gear (11) and the gear shaft (24) is coupled with a hollow wheel (21) via an elastic damping ring (34). The drive shaft (16) meshes with its outer toothing (19) in the internal toothing (20) of the hollow wheel. The hollow wheel (21) is received in a bearing (25) in the housing and the damping ring (34) is made of rubber or plastic, is inserted in the hollow wheel (21) and, surrounds the gear shaft (24 ). The external toothing (35) of the damping ring (34) engages in the internal toothing (20) of the hollow wheel (21) and the external toothing (33) of the gear shaft (24) intermeshes with the internal toothing (36) of the damping ring (34) so…
