PURPOSE:To simplify assembling manpower and prevent drop in reliability by arranging in piles an inner ring spacer and an outer ring spacer between bearings on the shaft of a bevel gear, and providing screw holes on the back surface of the outer ring spacer. CONSTITUTION:An inner ring spacer 12 and an outer ring spacer 13 are arranged in piles on the shaft of a bevel gear 11 between a bearing B1 contacted with the shoulder face 17 of the gear and bearing B2, B3 contacted with a bearing nut 15. Width l1 of the inner ring spacer 12 is instituted less than width l2 of the outer ring spacer by pre-load adjusting measure delta, and screw holes t1 are provided on the back surface of the outer ring spacer 13. Thus, adjustment of tooth contact by means of shim 19 can be performed without change of the instituted pre-load, assembling manpower can be simplified, and drop in reliability can be prevented. |
