Abstract

The invention relates to the technical field of bearing tests, and particularly discloses a wide-temperature-range four-dimensional drive joint bearing testing machine. The wide-temperature-range four-dimensional drive joint bearing testing machine at least comprises a machine body, a high-low temperature environment box, a testing unit positioned in the high-low temperature environment box, an X-axis loading assembly, an X-axis swinging assembly, a Z-axis loading assembly and a Z-axis swinging assembly. In the above structure, a to-be-tested bearing is simulated and tested in the sealing environment by arranging the high-low temperature environment box, the testing conditions under different temperatures can be simulated, so that the simulated testing contention is closer to a bearing running working status, and the testing result is more reliable; the testing machine is provided with a four-dimensional driving system composed of the X-axis loading assembly, the X-axis swinging assembly, the Z-axis loading assembly and the Z-axis swinging assembly, so that the testing working conditions demands of the joint bearing in two-dimensional swinging and two-dimensional push-pull load aremet.

Description

technical field [0001] The invention relates to the technical field of bearing testing, in particular to a wide temperature range four-dimensional drive joint bearing testing machine. 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-pu...
