齿轮6与轴2紧固装置,是由两个Ⅱ型卡板1和2组成,其中之一具有折弯端5。轴上位于卡板位置铣有相对切向的两槽4,深为0.5(d-b)。其中d为轴径,b为卡板开口宽。齿轮端面凸台上铣一直通槽,为了与卡板外侧配合。两卡板总厚度等于槽4的宽度。卡板1比卡板2的厚度要薄,而要长一个折弯端5的长度,两卡板的总厚度等于槽4的宽度。
The gear 6 and the shaft 2 fastening device are composed of two type II pallets 1 and 2, one of which has a bent end 5. Milling the shaft at the pallet has two troughs 4 of relatively tangential depth of 0.5 (d-b). Where d is the shaft diameter, b is the pallet opening width. Milling the gear end boss has been through slot, in order to cooperate with the outside of the card board. The total thickness of the two pallets is equal to the width of the slot 4. The thickness of pallets 1 is less than the thickness of pallets 2 and the length of one of the pallets 5 is equal to the total thickness of pallets 4.
