Housing for sealed electrical machine utilized e.g. as motor in steering system of motor vehicle, has base forming axial catch for bearing receptacle with bearing shield, where housing is manufactured by impact extrusion process

摘要

The housing (2) has a base (3) which forms an axial catch for a bearing receptacle (4) with a bearing shield (7), where the housing is manufactured by forward impact extrusion process, backward forward impact extrusion process or forward and backward impact extrusion process using aluminum forging alloy. The housing receives an armature shaft (10) and a stator (12), where the armature shaft is rotatably supported in bearings (15, 16). The housing forms a heat sink for an electrical machine (1). An independent claim is also included for an electrical machine comprising bearings.
