Truck hub bearing mud durability testing machine

Abstract

The invention discloses a truck hub bearing mud durability testing machine which comprises a rack, a test shaft is arranged on the rack in the length direction, a driving part used for driving the test shaft to rotate is further arranged at the position, corresponding to the test shaft, of the rack, and containing grooves used for containing and installing a hub bearing to be tested are formed in the two ends of the test shaft respectively. The two ends of the test shaft are further connected with side plates respectively, positioning seats are arranged on the side plates and are higher than the test shaft, an axial load loading mechanism is arranged between the positioning seats on the two side plates, a radial loading air cylinder is further arranged on the rack and corresponds to the position of the containing groove, the output end of the radial loading air cylinder is arranged in the height direction, and the output end of the radial loading air cylinder is rotationally connected with the positioning base. The testing machine is comprehensive in function, can carry out multiple tests, can effectively simulate the actual use condition, and has a good test effect.

Description

technical field [0001] The invention relates to the technical field of bearing detection. Background technique [0002] When the truck is running on the road, the hub bearing bears a large radial load, and bears an axial load when turning. And in rainy weather, because trucks usually drive on poor road conditions and muddy roads, it is also necessary to prevent mud from entering the hub bearings. In order to verify the load-carrying capacity, service life and sealing performance of the product, it is usually necessary to test the product when it leaves the factory, but The current test equipment has a single function, and can only simply test the axial or radial bearing capacity, or perform overall scouring to test its mud resistance ability. These tests need to be carried out one by one, which is time-consuming and laborious. Simulating the actual working conditions of the bearing makes the detection results not reliable enough and reduces the detection effect. Contents ...
