Embodiment Construction
[0018] For example, the specific embodiment of the composite oscillating joint bearing testing machine of the present invention Figure 1 to Figure 4 As shown, it includes a bearing fixture 1, the bearing fixture 1 is composed of two clamping blocks, the joint bearing 2 is clamped in the center of the bearing fixture 1, and on one side of the bearing fixture 1 along the joint bearing 2 The first transmission shaft 3 for transmission with the inner sleeve of the spherical joint bearing 2 is installed in the axial direction through the rotation of the bearing seat 7. The first transmission shaft 3 is connected with a first drive mechanism, which includes a first drive motor. 5. The first drive motor 5 is in transmission connection with the first transmission shaft 3 through the crank rocker mechanism 4 , and a frequency conversion controller 6 is connected to the first drive motor 5 . A first torque sensor 16 is mounted on the first transmission shaft 3 . The first transmission...

The invention discloses a compound swinging type joint bearing testing machine, comprising a bearing fixture, a first transmission shaft concentric with the bearing fixture for connecting the inner sleeve of a to-be-tested joint bearing in transmission manner, a first driving mechanism for driving the first transmission shaft to perform reciprocating and rotary swinging, and a loading mechanism for applying radial load to the joint bearing. A second transmission shaft is radially connected with the bearing fixture in transmission manner; the axes of the second and first transmission shaft are vertically intersected at the center of the to-be-tested joint bearing; and a second driving mechanism for driving the second transmission shaft to perform reciprocating and rotary swinging is connected on the second transmission shaft. The invention not only can test the frictional wear property of the axial swinging of the joint bearing, but also can test the frictional wear property of the swinging of the joint bearing in the radial inclined direction; the invention is closer to the practical working condition of the joint bearing, so that the tested data is more perfect and sufficient data support for solving the technical index of the service life of the joint bearing under the compound swinging state.
Description
technical field [0001] The invention relates to a test device for testing the friction and wear characteristics of bearings, in particular to a friction and wear testing machine for testing the service life of joint bearings in a composite swing state. Background technique [0002] In recent years, with the rapid development of industry, many industries, especially the military, aerospace and cutting-edge technology fields, have stricter requirements on the performance and reliability of joint bearings. Advanced testing equipment to ensure the quality of bearing products. [0003] Since joint bearings are widely used in various fields, their working conditions are complicated and changeable. At the same time, due to the unique geometric shape and motion characteristics of spherical plain bearings, the existing bearing friction and wear testing machines mainly use unidirectional rotary motion and linear reciprocating motion, which has a certain gap with the actual working co...
