Abstract
The utility model discloses a bearing fastening device, which comprises a bearing cover plate, a rivet pressing nut, a connecting bolt and a sealing washer. The bearing cover plate is an integrated pressing plate structure, at least three pre-locating holes are arranged on the bearing cover plate, and the rivet pressing nut is fixedly connected with the bearing cover plate; the connecting bolt passes through an unthreaded hole on a gearbox shell from the exterior of the gearbox shell and is connected with the rivet pressing nut, the bearing is tightly pressed between the bearing cover plate and the gearbox shell at the pre-locating holes, and the sealing washer is arranged between the connecting bolt and the gearbox shell. The utility model saves space and reduces the number of the parts so that the structure of a speed changer is more compact and rational.
Description
Technical field
The utility model relates to a kind of bearing fixing device, automotive transmission bearing fixing device specifically, and its restriction bearing moves axially, and bears the speed changer axial force.
Background technique
Bearing is applied in the various speed changers widely, owing to adopt slant gear transmission, helical gear transmission meeting produces certain axial force more in automotive transmission, and automotive transmission adopts deep groove ball bearing and cylindrical roller bearing to be used more.The deep groove ball bearing that is used to bear axial force just fixing device of needs limits moving axially of bearing and bears axial force.Traditional method adopts bearing cover to add that screw is fixed or shaft block ring more, perhaps hole back-up ring, and perhaps flange plate adds modes such as screw is fixing.But axle with or the hole fixedly have axial clearance with back-up ring, when bearing bears axial force, can produce axial float, influence the transmission quality of speed changer, it is relatively low that the while back-up ring bears the ability of axial force, is not suitable for high moment of torsion automotive transmission use.Adopt bearing cover or flange better relatively, can eliminate axial clearance, but the structure relative complex.If there are a plurality of bearings to fix, will take than large space, make the speed changer structure relative complex.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of and can be used for a plurality of bearing fixing, saves the space and can effectively bears the bearing fixing device of axial force, to overcome the above-mentioned defective that prior art exists.
The technological scheme of the utility model technical solution problem is as follows:
A kind of bearing fixing device, it is characterized in that, comprise bearing cover, riveting nut, connecting bolt and seal washer, the integrated pressure plate structure of described bearing cover, described bearing cover is provided with at least three preposition holes, described riveting nut is fixedlyed connected with bearing cover, described connecting bolt is connected with the riveting nut by the unthreaded hole on the gear box casing from the transmission housing external body, bearing is pressed between the bearing cover and gear box casing at place, preposition hole, and the seal washer pad is between connecting bolt and gear box casing.
The utility model automobile speed variator bearing fixing device can the fixed transmission spring bearing, bears the speed changer axial force.This bearing fixing device adopts the presser type structure.Being specially adapted to the triple axle speed changer uses.The triple axle speed changer has three spring bearings to need simultaneously to fix, and three bearings need three stationary platens.By adopting this device that three pressing plates are integrated into a part, well saved the space, connect with gear box casing by bolt then, bear axial force.Connecting bolt is tightened from outside in addition, makes that assembling is easier.Seal washer plays seal action, prevents the leakage of oil of bolt position, also can have two openings on the pressing plate, is convenient to the assembling of transmission shaft system.
The utility model has been saved the space, has saved the quantity of part, makes speed changer structure compact and reasonable more.

Embodiment
Below in conjunction with Fig. 1 and Fig. 2 structure of the present utility model is described in further details
As shown in Figure 1, the utility model bearing fixing device, comprise bearing cover 1, riveting nut 2, connecting bolt 3, seal washer 4, described bearing cover 1 integrated pressure plate structure, described bearing cover 1 is provided with three preposition holes 11, described riveting nut 2 is riveted or is welded with bearing cover 1 and fixedlys connected, described connecting bolt 3 is connected with riveting nut 2 by the unthreaded hole on the gear box casing from gear box casing 6 outsides, bearing 5 is pressed between the bearing cover 1 and gear box casing 6 at place, preposition hole, and seal washer 4 pads are between connecting bolt 3 and gear box casing 6.
Two preposition holes 11 are provided with opening 12 on the described bearing cover 1, are used for the assembling that convenient axle is.
1～2 millimeter gap is designed with the position of a gear box casing 6 and a cooperation that system is corresponding respectively in the edge of bearing cover 1 and three preposition 11 apertures, plays the preposition effect, makes connecting bolt 3 can be screwed into riveting nut 4 more easily.
