High-precision miniature bearing life test device

Abstract

The invention provides a high-precision miniature bearing life test device. The high-precision miniature bearing life test device comprises a box body, the two side walls of the box body are rotatably provided with the same two-way threaded rod, one end of the two-way threaded rod extends out of the box body and is fixedly provided with a hand wheel, the two opposite threaded sections of the two-way threaded rod are both provided with L-shaped supporting plates in a threaded mode, and the two opposite threaded sections of the two-way threaded rod are fixedly provided with the hand wheel. The bottom of the L-shaped supporting plate is in sliding contact with the inner wall of the bottom of the box body, the top of the L-shaped supporting plate is detachably provided with a bearing seat through a fastening bolt, a test bearing composed of a bearing outer ring, a bearing inner ring and a bearing ball is embedded in the bearing seat, and a transmission shaft is installed in the bearing inner ring through a bearing pin block. The high-precision miniature bearing service life test device provided by the invention has the advantages that a pressed rotation test can be carried out on the inner ring of the bearing, so that people are helped to analyze the use condition of the bearing under pressure.

Description

technical field [0001] The invention relates to the technical field of bearing detection and testing equipment, in particular to a high-precision miniature bearing life testing device. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The service life of the bearing is one of the important indicators of bearing quality. A life test is required to determine the service life of a bearing. [0003] Since most of the testing equipment currently used is to change the use environment of the bearing, the service life of the bearing in different environments is tested. In the actual use of the bearing, the installation direction and the force direction of the bearing are not fixed, and the inner and outer rings of the bearing are under pressure. Different friction causes the balls inside t...

Problems solved by technology

[0003] Since most of the testing equipment used at present is to change the use environment of the bearing, test the service life of the bearing in different environments, the actual bearing is in use, the installation direction and the force direction of the bearing are not fixed, and the inner and outer rings of the bearing are under pressure. different, resulting in different friction on the balls inside the bearing, resulting in the inner and outer rings of the bearing being prone to ring detachment
