Abstract

The invention relates to the technical field of bearing tests, and particularly discloses a steering bearing dynamic durability test device. The steering bearing dynamic durability test device at least comprises a test assembly, a deflection assembly, a main driving assembly, an axial loading assembly and a radial loading assembly, wherein the test assembly at least comprises a test shaft and a test base for installing a test bearing, and a test bearing installation cavity is formed in the test base. In the steering bearing dynamic durability test device, through utilizing the axial loading assembly, the radial loading assembly and the deflection assembly, an axial load and a radial load are simultaneously applied to the test bearing and the test bearing generates a deflection angle of anouter ring relative to an inner ring so that the steering bearing dynamic durability test device accords with a work condition environment of a steering bearing, and a dynamic endurance test result ismore accurate and reliable; and meanwhile, the steering bearing dynamic durability test device has the technical advantages of wider applicable bearing range and higher universality.

Description

technical field [0001] The invention relates to the technical field of bearing tests, in particular to a dynamic durability test device for steering bearings. Background technique [0002] In the prior art, there are many test devices for dynamic durability testing of bearings, but there are usually only two dimensions for the loading direction of the force of the test bearing, that is, the axial loading force and the radial loading force. The effect produced by the axial loading force is that the inner ring of the bearing moves axially relative to the outer ring to increase the friction of the rolling elements; Shift to increase the friction of some rolling elements. [0003] Regardless of the above-mentioned axial loading or radial loading, the common point is that the bearing outer ring moves axially or radially shifts relative to the inner ring, and the centerline of the bearing outer ring is always parallel to the centerline of the inner ring. In actual working condit...
