Abstract
The utility model discloses a main differential mechanism bearing pretightning force test fixture that subtracts, subtract the shell including main, the differential mechanism installation cavity, the differential mechanism bearing, the bearing cap, holding ring at differential mechanism installation cavity both ends sets up first, second component in the differential mechanism installation cavity set up pressure sensor between first, the second component, pressure sensor connection pressure test equipment, the pretightning force that pressure sensor is used for detecting when regulation holding ring to the bearing cap volume of rising is a definite value, first member bore. The utility model discloses a pressure value that obtains that detects when adjusting the two bearing cap diagonal volumes of rising to proper range to whether the pretightning force of verifying the differential mechanism bearing that selects accords with the designing requirement.
Description
Technical field
The utility model relates to master and subtracts differential mechanism bearing pre-fastening test fixture.
Background technology
Automobile main reduction gear when loading runs bears very big load, and therefore, main reduction gear neck bearing must have suitable preliminary tension when assembling, and suitable preliminary tension can improve support stiffness and the running accuracy of main reduction gear. As excessive in preliminary tension or cross and little can affect part performance, preliminary tension is crossed conference and is caused bearing life to reduce ablation phenomen occur, and it is low that preliminary tension crosses little then support stiffness, abnormal sound easily occurs. Therefore, differential mechanism bearing must be subtracted to master and apply suitable preliminary tension, at present, the main test subtracting differential mechanism bearing pre-fastening is judged by the detection Assembly of the parts amount of rising, adjustment ring regulates the difference of the step cover diagonal distance of front and back to be the amount of rising, and namely the amount of rising is judged as that in OK range preliminary tension is suitable, but, judge it is very rough like this, cannot verify whether the preliminary tension value of differential mechanism bearing meets design requirements.
Practical novel content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of master to subtract differential mechanism bearing pre-fastening test fixture, can test differential mechanism bearing certain rise value time preliminary tension, thus whether checking meets design requirements, to overcome the deficiencies in the prior art.
The technical scheme in the invention for solving the technical problem is: master subtracts differential mechanism bearing pre-fastening test fixture, comprise master and subtract shell, chamber installed by differential mechanism, differential mechanism bearing, step cover, the adjustment ring at two ends, chamber is installed at differential mechanism, install in chamber at differential mechanism and first, second component is set, between first, second component described, pressure transmitter is set, described pressure transmitter Bonding pressure testing apparatus, described pressure transmitter is for the preliminary tension detecting when regulating adjustment ring to the step cover amount of rising to be certain value, the first component bears.
First, second component described extend in the differential mechanism bearing that two ends, chamber installed by differential mechanism respectively.
The described step cover amount of rising be by detection step cover two diagonal lines before adjustment after deformation length obtain.
The scope of the described step cover amount of rising is between 0.25 0.35mm.
The beneficial effects of the utility model are:
The utility model is by regulating the two bearings lid diagonal lines amount of rising to being detected the force value obtained during OK range, thus whether the preliminary tension of the selected differential mechanism bearing of checking meets design requirements.
When the utility model also can be verified within the scope of the preliminary tension reaching regulation, whether the amount of rising actual value goes beyond the scope, thus whether verify that differential mechanism bearing connection cover and master subtract shell differential mechanism bearing fixed seat rigidity enough.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Figure 1-5, master of the present utility model subtracts differential mechanism bearing pre-fastening test fixture, comprise master and subtract shell 1, chamber installed by differential mechanism, differential mechanism bearing 7, step cover 6, the adjustment ring 2 at two ends, chamber is installed at differential mechanism, install in chamber at differential mechanism and the first component 3, second component 5 are set, between first, second component described, pressure transmitter 4 is set, described pressure transmitter Bonding pressure testing apparatus, described pressure transmitter is for the preliminary tension detecting when regulating adjustment ring to the step cover amount of rising to be certain value, the first component bears.
First, second component described extend in the differential mechanism bearing 7 that two ends, chamber installed by differential mechanism respectively.
The described step cover amount of rising be by detection step cover two catercorner length (X, Y) before adjustment after distortion measure.
The scope of the described step cover amount of rising is between 0.25 0.35mm. As shown in Figure 2, before adjustment ring regulates, the cornerwise length of step cover two is respectively X1, Y1, after adjustment ring regulates, the cornerwise length of step cover two is respectively X2, Y2, and the step cover value that rises is: (X2-X1), (Y2-Y1), and, two values that rise control between 0.25 0.35mm.
The foregoing is only better embodiment of the present utility model; and it is not used in restriction of the present utility model; all do within spirit of the present utility model and principle any amendment, the equivalent improvement etc. replaced and do without creative work, all should be included within protection domain of the present utility model.
