Electrical rotating machine e.g. internal combustion engine starter, for motor vehicle, has cylinder head comprising external part with length shorter than that of internal part for increasing external thickness of cylinder head

摘要

The machine has a cylinder head inserted between a front bearing (21) and rear bearing (9). An external assembling device mounts the rear bearing to the front bearing and clamps the cylinder head between the bearings. The cylinder head has an external part (122) with length shorter than that of an internal part (22) for increasing external thickness of the cylinder head. The assembling device has studs (123) configured such that the parts surround the increased thickness of the cylinder head.
