Example Embodiment

[0046] Example 1 of a bearing test machine based on three-way vibration:

[0047] Such as Figure 1 to 6As indicated, the bearing test machine based on three-way vibration includes a cement box 11, a test bench is mounted on the cement box 11, and floating above the test bench is equipped with a test body, and the test body includes a main base 18 and a body cover 19, the main base 18 With the bearing support, the bearing support is used to support bearings assembled on the test shaft 37.

[0048] In the present embodiment, the test bench includes a base 23 and an adjustment table 26, and the adjustment stage 26 is mounted on the base 23 along the axial direction of the test shaft 37. Specifically, such as Figure 3 to 5 As shown, the upper side of the base 23 is provided with a T-slot along the axial direction of the test shaft 37, and a bolt is connected to the adjustment stage 26, and the bolts are arranged in the axial intervals of the test shaft 37, and the bolt head of each bo...

Example Embodiment

[0064] Example 2 of a bearing test machine based on three-way vibration:

[0065] The difference from the first embodiment is that in the first embodiment, the damper member is a rubber block 24; in the present embodiment, the damper member is a compression spring.

Example Embodiment

[0066] Example 3 of a bearing test machine based on three-way vibration:

[0067] The difference from the first embodiment is that in Example 1, a guide rod is provided between the test body and the test stage, and the rubber block 24 is set on the guide rod to ensure the stability of the rubber block. In this embodiment, the test bench is fixed to a restricted sleeve, and the rubber block is placed within the limit sleeve to ensure the stability of the rubber block, wherein the rubber block is higher than the limit sleeve to avoid the test body compression rubber. When blocking the limit sleeve, affect the test results.

Abstract

The invention relates to a bearing testing machine based on three-direction vibration. The bearing testing machine based on three-direction vibration comprises a test bench; a test main body arranged above the test bench; a radial loading device used for applying a radial acting force to the test shaft; a driving device which is arranged on one side, in the axial direction of the test shaft, of the test main body and used for driving the test shaft to rotate; a transverse vibration device which is arranged on the other side, in the axial direction of the test shaft, of the test main body and used for providing transverse vibration; a vertical vibration device which is arranged on one side of the test main body in the vertical direction and is used for providing vertical vibration; a longitudinal vibration device which is arranged on one side of the test main body in the horizontal direction and is used for providing longitudinal vibration; and an air spring which is positioned between the test main body and the test bench so that the test main body is assembled above the test bench in a floating manner. The test main body is assembled above the test bench in a floating manner through an air spring so as to ensure that the test main body can vibrate in the transverse direction, the longitudinal direction and the vertical direction.

Description

technical field [0001] The invention relates to a bearing testing machine based on three-way vibration. Background technique [0002] Bearings are the key components of mechanical systems, and they need to pass the operation test to meet the national standard before they can be put into use. Through the bearing operation performance test, the bearing can be comprehensively and accurately tested, analyzed and studied, and a systematic and effective optimization design scheme can be proposed. [0003] The Chinese invention patent application with the application publication number CN112098091A discloses a rolling bearing dynamic testing machine based on active vibration, including a driving device, a test body, a radial loading device, an axial loading device, an axial vibration device, a radial vibration device and The base, the test body adopts a groove structure, and is positioned and installed on the V-shaped slide rail of the base; the driving device and the main shaft of...
