Multi-station fatigue life test bench

Abstract

The invention discloses a multi-station fatigue life test bench which is mainly composed of a first end cover, a second end cover, a first sleeve, a second sleeve and a third sleeve, the first sleeve, the second sleeve and the third sleeve are located between the first end cover and the second end cover, the edge side of the first end cover is connected with the first sleeve, and the outer wall of the first sleeve is fixedly connected with a limiting block. A second sleeve is connected to the outer side of the limiting block, a third sleeve is connected to the left side of the second sleeve in an attached mode, and a second end cover is connected to the left side of the third sleeve. The multi-station fatigue life test bench includes a rotating shaft which is movably installed in the first end cover, an elastic sleeve is fixedly connected to the outer wall of the left side of the rotating shaft, a connecting bearing is connected to the outer side of the elastic sleeve, and a space ring is connected to the side of the connecting bearing in an attached mode. The multi-station fatigue life test bench can test a plurality of groups of connecting bearings at the same time, and can test the connecting bearings of various specifications through the arrangement of the connecting blocks, thereby improving the detection efficiency.

Description

technical field [0001] The invention relates to the technical field of bearing detection, in particular to a multi-station fatigue life test bench. Background technique [0002] Bearing is a mechanical element that reduces the friction between moving parts. Before the bearings are put into the market in large quantities, the service life of the bearings needs to be tested, and then the bearing fatigue life testing machine needs to be used. For this purpose, a matching fatigue life side is designed for this case. A multi-station fatigue life test bench for video cameras. [0003] Now the traditional fatigue life testing machine is a single set of bearings, which are installed on the bearing seat of the testing machine. The inner ring and the bearing seat steps cooperate to rotate, and the outer ring bears the radial load. The original device can only test one set of bearings at the same time. When conducting comparative tests, there are certain variables, which are unfavorab...

[0003] Now the traditional fatigue life testing machine is a single set of bearings, which are installed on the bearing seat of the testing machine. The inner ring and the bearing seat steps cooperate to rotate, and the outer ring bears the radial load. The original device can only test one set of bearings at the same time. When conducting comparative tests, there are certain variables, which is unfavorable for the test plan of the control variable method, and the original device can only test several fixed types of bearings
