Abstract

The invention discloses a device capable of simultaneously carrying out axial loading detection on multiple pairs of bearings. The device comprises a base, wherein the base is provided with a test component, a loading component and a driving component; the test component is used for installing multiple pairs of test bearings; the loading component is used for simultaneously applying an axial loadto the multiple pairs of test bearings; the driving component is used for driving the multiple pairs of test bearings to synchronously rotate; the test component comprises a shell, wherein a cylindrical inner cavity used for placing multiple pairs of test bearings is arranged in the shell; the inner wall of the cylindrical inner cavity is providedwith thick ball bearings in a pasted manner; multiple pairs of test bearings are independently sheathed to respective spindles correspondingly; the plurality of spindles are arranged in sequence along the axial direction of the cylindrical inner cavity; the outer circumferential surfaces of each pair of test bearings are independently fitted with the inner wall of one respective outer bushing; the outer wall of each outer bushing is independentlyfitted with the ball of each thick ball bearing; a spacer bush is arranged between every two adjacent outer bushings; and a sensor used for detecting test bearing data is inserted on the shell. Therefore, multiple pairs of bearings can be simultaneously detected, detection efficiency is improved, and the bearing can be conveniently disassembled and replaced.

Description

technical field [0001] The invention relates to the field of bearing detection, in particular to a device capable of simultaneously performing axial load detection on multiple pairs of bearings. Background technique [0002] Bearings are key components of mechanical equipment, and their performance and reliability directly affect the performance and reliability of mechanical equipment. With the development of science and technology, bearings are widely used in the fields of high-speed railways and aerospace. They are usually used in harsh environments and withstand severe load impacts. The state of the bearings during operation directly affects the performance of trains and aircraft. Safety. Today, the performance and demand for bearings are getting higher and higher, and while continuously improving the performance and reliability of bearings, it is a key issue to ensure their performance and stability within the rated life. For bearings that bear axial loads, such as ang...

AI Technical Summary

Problems solved by technology

For bearings that bear axial loads, such as angular contact ball bearings, the main failure mode during operation is the wear of the inner and outer rings of the bearing due to axial loads, which increases the gap between the inner and outer rings of the bearing, causing bearing vibration and wear In severe cases, it may also lead to the failure of related components

However, the existing devices that can apply axial loads to bearings and test bearing performance have single functions, and can only test a pair of bearings, and it is inconvenient to disassemble and assemble the test bearings. In actual use, a pair of bearings can be tested The efficiency and the efficiency of replacing the next pair of bearings are low; and in some equipment, multiple pairs of bearings are required to cooperate to bear the axial load. The existing device for testing bearing performance cannot simulate the axial load shared by multiple pairs of bearings. The working condition of each pair of bearings can only be calculated separately to obtain the axial load shared by each pair of bearings in the whole machine, and then simulate the situation of each pair of bearings working alone, and it is impossible to accurately detect the performance of multiple pairs of bearings sharing the axial load
