Measurement instrument for radial loading torque of bearing

Abstract

The invention provides a measurement instrument for the radial loading torque of a bearing, and the measurement instrument comprises a drive device, a torque sensor, a support seat, a loading device,an outer ring fixing device, and a control unit. One end of the torque sensor is connected with the drive device through a first shaft coupler, and the other end of the torque sensor is connected withone end of a rotating shaft through a second shaft coupler, wherein the other end of the rotating shaft passes through an inner ring of a bearing sample, and an outer ring of the bearing sample is provided with the outer ring fixing device which is used for fixing the outer ring of the bearing sample. The outer ring of the bearing sample is provided with the loading device, and the control unit is connected with the drive device, the torque sensor, and the loading device. The measurement instrument is simple in implementation operation, is accurate in test result, is convenient in testing andinstallation and is stable in test process. Moreover, a torque value can be displayed through the graphic data during the test, which is more visual and clear, and facilitates the inquiry for findingthe defects.

Description

Technical field [0001] The invention relates to the field of torque testing or bearing experiment, in particular to a bearing radial load torque measuring instrument. Background technique [0002] At present, most of the experimental equipment on the market that can detect bearing torque uses a connecting rod structure to drive the reciprocating motion of the test shaft with an eccentric wheel. Affected by the connecting rod mechanism, this type of equipment generally has low reciprocating frequency, bulky equipment, and relatively large test factors. Multiple test data is not accurate. In addition, the traditional test equipment adopts the linkage mechanism and requires more tooling to be replaced each time the product under different test conditions is changed, which is complicated to install and wastes manpower. [0003] The torque test equipment commonly used on the market has the following shortcomings: the number of sampling points is small; the test results are not intuitiv...
