To balance the fatigue life of each bearing and enable a compact package.SOLUTION: A drive unit includes a pair of bearings and a reduction gear assembly 12 with a first drive gear mounted on and coaxial with a main shaft of a motor, and a first driven gear 52 is rotatably coupled to the first drive gear 50 and mounted on and coaxial with an intermediate shaft 42 to thereby form an intermediate shaft assembly. The reduction gear assembly includes a second drive gear 58 mounted on and coaxial with the intermediate shaft, and a second driven gear 60 rotatably coupled with the second drive gear. A first bearing 72 of the pair of bearings is mounted on a bulkhead 62 and on the intermediate shaft assembly between the first driven gear and the second drive gear to thereby reduce the distance between the first and second bearings.SELECTED DRAWING: Figure 1

    【課題】軸受の疲労寿命のバランスをとると共に、コンパクトなパッケージを可能にする。【解決手段】駆動ユニットは、一対の軸受および減速ギアアセンブリ12を含み、第1の駆動ギアは、モータのメインシャフトに装着されるとともに同軸であり、第1の被駆動ギア52は、第1の駆動ギア50に回転可能に結合され、中間シャフト42に装着されるとともに同軸であり、それによって中間シャフトアセンブリを形成する。減速ギアアセンブリは、中間シャフトに装着されるとともに同軸である第2の駆動ギア58と、第2の駆動ギアと回転可能に結合される第2の被駆動ギア60とを含む。一対の軸受の第1の軸受72は、バルクヘッド62に装着されるとともに、第1の被駆動ギアと第2の駆動ギアの間の中間シャフトアセンブリに装着され、それによって第1の軸受と第2の軸受の間の距離を減少させる。【選択図】図1
