Pressing plate 5 is flat dish type, and pressing plate 5 center is provided with circular hole and uniform three through holes of circular.
Upper and lower roller bearing is back-to-back arranged in the through hole of carrier gear 4, and through hole internal diameter size and the roller bearing 2 outer ring outside dimension of carrier gear 4 are interference fit size, and by back-up ring 3 interval on carrier gear 4 through hole inner ring groove.The internal diameter of upper and lower roller bearing is set in the large footpath section of bridge gear shaft 1, and footpath broad in the middle size and the roller bearing 2 inner ring internal diameter size of bridge gear shaft 1 are transition fit size.Lubricant oil oil discharge passage 6 in the section of bridge gear shaft 1 large footpath is corresponding with the back-up ring 3 on carrier gear 4 circular groove groove.Bridge gear shaft 1 is arranged on body by pressing plate 5 and three hexagon socket head cap screws, and down, and neck is set on the circular hole of pressing plate 5 in lubricant oil oil inlet passage 7 direction of bridge gear shaft 1 one path axle head.The neck size that the center hole size of pressing plate 5 and bridge gear shaft 1 are provided with the miner diameter end of lubricant oil oil inlet passage 7 is Spielpassung size.The disk diameter of pressing plate 5 is dimensioned slightly smaller than roller bearing 2 inner ring outside dimension.Bridge gear shaft 1 footpath broad in the middle segment length size is slightly larger than the thickness size of two roller bearings 2 and a back-up ring 3 thickness size sum.
Advantageous Effects of the present utility model embodies in the following areas:
1. the utility model adopts roller bearing bearing capacity large, and the rationality of this structure directly affects the reliability of gear, and contributes to the noise reducing motor;
2. the pressure lubrication that the utility model is good helps avoid the high temperature wear of bearing, effectively extends the working life of assembly.
Accompanying drawing explanation
