摘要

The spur gear has a housing (22) and a shaft (7) which is supported by a drive bearing (11), and a bearing (25) is supported in the housing. A drive side end area of the shaft is protruded from the housing. A pinion gear (1) arranged in housing is fastened on a drive shaft of a motor, and is cogged with a gear-wheel (2). The housing has a section corrugated at a side surface, which forms the corrugated edge of the two sections (30,32).
