Abstract

The invention belongs to the testing technological field and discloses a bearing dynamic friction torque tester. The bearing dynamic friction torque tester comprises a host, a controller, and a display; and the bearing dynamic friction torque tester is a bearing detection device. The bearing dynamic friction torque tester is driven by a precision spindle at a rate of 1r / min (or 0.5r / min or 10r / min) to drive a bearing under test to rotate at a low speed; under an actual preload condition, the dynamic torque of the bearing is detected by a dynamometer, and a test curve is displayed in real time;bearing quality information such as bearing tracks, steel ball surface smoothness, groove surface smoothness, cleanliness, lubrication states and friction torque mean values can be judged by means ofcontinuous torque curve analysis; and therefore, with the bearing dynamic friction torque tester adopted, the quality control of the bearing can be carried out, the improvement of the accuracy of a product and the prolonging of the service life of the product can be benefitted. The bearing dynamic friction torque tester can be a device used by a bearing user to carry out bearing screening and bearing quality inspection.

Description

technical field [0001] The invention belongs to testing technology, and relates to a bearing dynamic friction torque tester. Background technique [0002] In the development and production of gyro, the rotational speed of the gyro motor is very high, and the quality of the bearing and the cleanliness of the bearing have a great impact on the performance of the gyro. In order to eliminate the impact of bearing quality, a measuring instrument for dynamic friction torque of bearings is needed, which is used to test bearing quality, screen bearings, and check the cleanliness of bearings. There is no domestic product that meets the demand. Therefore, a dynamic friction torque measuring instrument for bearings has been developed by itself, and it has been extended to the application fields of bearing development and aerospace. Contents of the invention [0003] The purpose of the present invention is to provide a bearing dynamic friction torque tester for measuring the dynamic ...
