Embodiment Construction

[0025] The embodiment of bearing static performance test device, such as Figure 1-4 As shown, the test device includes a base 11, a test head assembly, a test loading mechanism and a test value acquisition system.

[0026] The base 11 is the basis for carrying the entire test device. In this embodiment, the base 11 is a horizontal workbench.

[0027] In this embodiment, the test head assembly is arranged on the base 11 through a stepped shaft support seat 12 with a small top and a large bottom. Among them, the support seat 12 and the base 11 are fixed and assembled together by screws. The test head assembly includes a mandrel 13, an outer ring pressure plate 14 and an inner ring pressure plate 15. The mandrel 13 is a stepped shaft, including the upper small diameter section and the lower one. The large-diameter section, wherein the small-diameter section forms an inner ring installation section, and the inner ring installation section is used to install the inner ring of the...

Abstract

The invention relates to the technical field of testing bearings, especially to a bearing static performance testing apparatus. The bearing static performance testing apparatus comprises a pedestal, a test head assembly and a test loading mechanism are arranged on the pedestal, and the test loading mechanism comprises an axial force loading mechanism and a turnover force loading mechanism. The turnover force loading mechanism comprises a force transmission arm, which has a force input end and a force output end for transmitting axial force to a bearing to be tested. The force loading direction of the axial force loading mechanism is always the same with the axis extension direction of the bearing to be tested. Since the test loading mechanism comprises an axial force loading mechanism and a turnover force loading mechanism, and the force loading direction of the axial force loading mechanism is always the same with the axis extension direction of the bearing to be tested, the loading means is more suitable for the actual conditions of a bearing. The bearing static performance testing apparatus can accurately simulates the state of the bearing subjected to a turnover force, and the accuracy of test results of static bearing features can be improved.

Description

technical field [0001] The invention relates to the technical field of bearing testing, in particular to a bearing static performance testing device. Background technique [0002] With the development of science and technology and the continuous increase of labor costs, the manufacturing industry is developing rapidly towards automation and intelligence. As an important embodiment of advanced manufacturing, robotics and related industries have also developed rapidly. Robot bearings are the key supporting components of industrial robots, which have a very important impact on key indicators such as the robot's smooth operation, repeat positioning accuracy, motion accuracy and work reliability. [0003] In China, due to the late start of robot application engineering, its supporting bearings are generally imported together with the main engine. Industrial robot bearings are a relatively weak link. The existing national standards for bearings cannot meet and guide the design an...
