ATLANTIC SHAFT, DEVICE FOR ASSEMBLING A DIFFERENTIAL UNIT USING AN ATTRACTION SHAFT, AND METHOD FOR PRODUCING A DIFFERENTIAL UNIT

摘要

There is a dummy wave disclosed that prevents slices from falling out. In addition, there is disclosed an apparatus for assembling a differential unit using the dummy shaft and a method of manufacturing the differential unit. More specifically, a dummy shaft (2) for temporarily assembling a differential unit (1) is disclosed, which is inserted into a drive gear (12) and a pulley (14) in contact with an outer surface (12w) of the drive gear (12) and a body portion (21) and a movable portion (22) slidable in a direction toward the body portion (21) or away from the body portion (21). The movable portion (22) has a receiving groove (22d) for engaging the disc (14).
