Abstract
The utility model relates to a regulation device for a differential gear bearing of a forward drive axle of a wheel-typed tractor, comprising a central transmission shell, a differential gear assembly and two differential gear bearings. The two differential gear bearings are respectively arranged in and connected with two bearing seats with a bearing shoulder; the bearing seats which can move axially are arranged in and connected with a shaft hole of a central transmission shell; regulation bolts screwed on the bearing seats are limited by a stopplate. By changing the manner of regulating the differential gear bearing and regulating the installation position of the bearing with the regulation bolts on the bearing seats, the utility model not only provides convenient and simple regulation, but also reduces processing precision requirements to the central transmission shell, thereby improving technique properties of the central transmission shell and ensuring the regulation of bearings to be done directly inside the central transmission shell, which reduces labor intensity; meanwhile, repair and maintenance can be done to the central transmission part after a cap board of the central transmission shell is opened, which brings convenience for assembly, regulation and maintenance of the forward axle.
Description
Technical field
The utility model relates to a kind of setting device of front driving axle differential bearing of self-propelled vehicle, especially relates to a kind of setting device of wheel-tire tractor front driving axle differential bearing.
Background technology
Because whether the large and small conical gear tooth mesh in the wheel-tire tractor before driving main gear is normal, directly affect the service life of gear, and the axial force that produces in the work of before driving central driver gear, then by two pairs of differential bearing supportings, when differential bearing has a spot of wearing and tearing, then the axial location variation to gear has great influence, makes the auger tooth leave original normal engaged position, so need adjust the two bearings installation site.And the adjustment of wheel-tire tractor front driving axle differential bearing at present, substantially be to realize by the bearing cap shim between increase and decrease semiaxis housing and the main gear casing joint surface, so this kind bearing is adjusted structure, not only higher to the working accuracy of central drive shell body, and installing and keeping in repair in the adjustment process, must carry out the increase and decrease of pad by the semiaxis housing of dismounting both sides, the adjustment process complexity, and difficulty is big, operation is loaded down with trivial details.
Summary of the invention
Technical problem to be solved in the utility model a kind of adjust a bearing wheel-tire tractor front driving axle differential bearing setting device easily when improving main gear housing shop characteristic and installation and maintenance is provided.
The utility model is that the technical scheme that solves the problems of the technologies described above is: a kind of wheel-tire tractor front driving axle differential bearing setting device, comprise main gear housing, differential assembly, two differential bearings, it is characterized in that: described differential bearing is installed in respectively in two bearing seats that have a shaft shoulder and by differential casing and supports, can be installed in the axis hole of main gear housing by axially movable bearing seat, the setting nut that screws on bearing seat is spacing by locking plate.
The utility model adopts the advantage of technique scheme to be: because by the adjustment nut on the adjusting shaft bearing, bearing seat drive differential axle is made to be moved axially, the not only convenient differential bearing axial distance of adjusting, and need not the semiaxis housing of dismounting both sides, adjust fast, alleviated labour intensity.Owing to can reduce the requirement on machining accuracy of main gear housing, and directly offer window at the top of main gear casing, improve the shop characteristic of main gear housing, the adjustment of differential bearing can directly be finished in the main gear housing.Simultaneously, in maintenance process,, just can keep in repair and maintain, make things convenient for assembling, adjustment and the maintenance of propons central running part as long as open the cover plate of main gear housing.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, wheel-tire tractor front driving axle differential bearing setting device of the present utility model comprises main gear housing 7, differential assembly 6, two differential bearings 8.Two differential bearings 8 are contained in respectively in two bearing seats 5 that have a shaft shoulder, and by the two-side supporting of differential casing 6-1, can be installed in the axis hole of main gear housing by axially movable bearing seat 5,4 of setting nuts screw on bearing seat 5, setting nut 4 is then placed restrictions on rotation by locking plate 3.For ease of dismounting and maintenance, the periphery of its bearing seat 5 has the axial retention groove, and a stop screw 2 or bearing pin pass main gear housing 7 and be arranged in the axial retention groove of bearing seat 5, and when preventing adjustment nut 4 rotary courses, bearing seat 5 rotates.Locking plate 3 one sides as shown in Figure 1 are fixedly connected on the main gear housing 7 by bolt 1, and the other end of locking plate 3 is stuck in the notch of setting nut 4.
When adjusting differential bearing 8, open the upper cover plate of main gear case, unclamp bolt 1 and locking plate 3, adjust setting nut 4 bearing seat 5 is moved axially, differential bearing 8 also moves thereupon, when being adjusted to the normal engage position of bevel gear wheel, one end of locking plate 3 is snapped in the groove of adjustment nut 4, tight a bolt 1, locking adjustment nut 4 is finished the adjustment of differential bearing 8.
