Abstract

The invention belongs to testing technology and discloses a bearing dynamic friction torque tester. Including host computer, controller and monitor. The bearing dynamic friction torque tester is a bearing testing device. Driven by a precision spindle at a rate of 1r / min (or 0.5r / min or 10r / min), it drives the tested bearing to rotate at a low speed. Under actual preload conditions, the dynamometer detects the dynamic moment of the bearing and displays the test in real time. Through continuous torque curve analysis, the bearing quality information such as bearing track, steel ball surface finish, groove surface finish, cleanliness, lubrication state and average friction torque can be judged. Therefore, the bearing dynamic friction torque tester can be used to control the quality of bearings, which is conducive to improving the accuracy and service life of products. At the same time, it is also the equipment for bearing users to screen bearings and test bearing quality.

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 ...
