Specific embodiment
The present invention is further elaborated with reference to the accompanying drawing.
As shown in figs. 1-7, the utility model provides a kind of bearing pre-fastening adjustment structure of penetrating bridge retarder, including circle
Stud wheel axis is equipped with tapered roller bearing 4 on the axle journal of cylindrical gear shaft 8, and tapered roller bearing 4 is resisted against cylindrical gear shaft
On 8 shoulder, there is gasket 3 between the inside convex edge and tapered roller bearing 4 of cylindrical gear shell 5, gasket 3 is by two semi-rings
Matrix composition, the gap between the convex edge and flange assembly 1 of cylindrical gear shell 5 are provided with oil sealing 2, and oil sealing 2 is nested with total in flange
At on 1 diameter of axle, the inner ring surface of annular gasket 3 is resisted against on the diameter of axle of oil sealing 2, and the splined shaft and flange of cylindrical gear shaft 8 are total
It is connected at 1 splined hole, the end face of flange assembly 1 is bonded with the inner ring end face of tapered roller bearing 4.The thickness of the gasket
For 0.1-1.5cm.
The utility model is applied to speed reducer assembly, and tapered roller bearing 4 is packed into the diameter of axle of cylindrical gear shaft 8, Cylinder Gear
The distribution hole of wheel shell 5 is aligned with the distribution threaded hole of reducing gearbox 7, is connected with bolt 6, while the circular hole 10 of cylindrical gear shell 5
Cooperate with the diameter of axle of tapered roller bearing 4；Using the outer ring end face of press-loading device pressure tapered roller bearing 4, reach standard preload
Power is packed into the semicircle of two suitable thickness between the outer ring end face of tapered roller bearing 4 and the circular hole end face of cylindrical gear shell 5
