Four-dimensional motion separation mechanism applied to bearing test

Abstract

The invention relates to the technical field of bearing tests, and particularly discloses a four-dimensional motion separation mechanism applied to a bearing test. The four-dimensional motion separation mechanism at least comprises a workbench, a bearing test tool, an inner ring follow-up assembly and an outer ring follow-up assembly. In the structure, an inner ring and an outer ring of a bearingto be tested are subjected to structure separation through a test shaft assembly and an outer ring fixing piece; reciprocating swing and axial push-pull load borne by the inner ring of the bearing tobe tested are separated through the inner ring follow-up assembly; deflection motion and radial push-pull load borne by the outer ring of the bearing to be tested are separated through the outer ringfollow-up assembly, thereby providing structural basis for test equipment of the joint bearing, allowing the bearing to be tested to realize swing in two dimensions and bear push-pull loads in two dimensions at the same time without interfering with each other, and making the simulation test of the joint bearing closer to the actual working condition; and the test result is more accurate and reliable.

Description

technical field [0001] The invention relates to the technical field of bearing tests, in particular to a four-dimensional motion separation mechanism applied to bearing tests. Background technique [0002] Spherical joint bearings are general-purpose parts of machinery, with the characteristics of small size and large load-carrying capacity. In actual work, this type of bearings is widely used in aviation, aerospace, trains, automobiles, mining machinery, machine tools, engineering machinery and other fields. [0003] The dynamic life of spherical plain bearings is generally evaluated by a simulation test machine. Since the above-mentioned spherical plain bearings usually need to bear four dimensions of loading, they are: the reciprocating deflection of the outer ring around the radial direction, the two-way push-pull load of the outer ring along the radial direction, The reciprocating swing or rotation of the inner ring around the axis, and the bidirectional push-pull of th...
