Embodiment Construction

[0017] Such as Figure 1 to Figure 3 As shown, an embodiment of a composite swing type joint bearing life testing machine, the testing machine in this embodiment includes a first axial transmission shaft 1 and a second axial transmission shaft 20 arranged in parallel, and the two axial transmission shafts are used for The inner ring of the joint bearing to be tested is connected by coaxial transmission, and each axial transmission shaft is rotatably assembled in two bearing seats. The two ends of each axial drive shaft here are respectively installed with two flanges through a key connection structure. The flange 7 is equipped with a pin shaft 8 through the end face positioning, and the flange 7 is connected by bolts. The pin shaft 8 is fixedly connected to the pin shaft plate 8. The side of the pin shaft plate 8 away from the flange plate 7 is convexly provided with a pin shaft arranged coaxially with the axial drive shaft for assembling the joint bearing 10, when the joint be...

Abstract

The invention discloses a composite swing type joint bearing service life testing machine. The composite swing type joint bearing service life testing machine comprises axial transmission shafts which are in coaxial transmission connection with inner rings of joint bearings, bearing clamps for clamping outer rings of the joint bearings and radial transmission shafts which are in transmission connection with the bearing clamps. The axes of the radial transmission shafts and the axes of the axial transmission shafts are vertically intersected, and the axial transmission shafts and the radial transmission shafts are all in transmission connection with corresponding driving devices for driving the corresponding transmission shafts to rotate and swing in a reciprocating mode. The at least two axial transmission shafts and/or the at least two radial transmission shafts are respectively parallelly arranged. The radial transmission shafts and the axial transmission shafts are crossed to form a testing machine rack for simultaneously testing at least two joint bearings. The testing machine rack is provided with at least two crossed positions which are formed by correspondingly intersecting the axes of the radial transmission shafts and the axes of the axial transmission shafts, and a bearing clamp is correspondingly arranged at each crossed position. The composite swing type joint bearing service life testing machine can simultaneously test at least two joint bearings, and the service life testing efficiency of the joint bearings is improved.

Description

Technical field [0001] The invention relates to a joint bearing life testing machine. Background technique [0002] The joint bearing is a spherical sliding friction swing bearing, which includes an inner ring with an outer spherical surface and an outer ring with an inner spherical surface. The service life and reliability of the joint bearing are the most important performance of the joint bearing. Most joint bearing life testing machines can only test one set of bearings, which is time-consuming and laborious and the reliability of the test results is poor. However, the life test of multiple sets of bearings can be performed at one time, which can greatly shorten the test time, reduce the test cost, and speed up the product The development cycle and the pace of improvement, therefore, the testing machine that can carry out multiple sets of bearing life tests at a time has attracted more and more attention, research and application. [0003] At present, there are many testing ma...
