Abstract

The invention discloses a rolling bearing oil churning loss testing device and method. By setting a bearing seat for installing the bearing to be tested in the test box, the oil outlet of the main oil inlet pipeline in the test box is used to supply the bearing to be tested. Lubricating oil, using the oil outlet at the bottom of the test box to realize the recycling of lubricating oil, the output shaft of the motor is connected to the main shaft for installing the bearing to be tested, and the output shaft of the motor is equipped with a speed and torque sensor for collecting the speed and torque of the main shaft. The main shaft and the side wall of the test box are sealed and connected, and the main oil inlet line is connected to the constant temperature and constant pressure oil supply system. The adjustment of the infiltration amount realizes the oil churning loss of the bearing under different lubricating oil working conditions. The structure of the invention is simple, and the sealed box and the lubricating oil system can accurately realize the rapid detection of the churning oil loss under the bearing working condition, which improves the detection efficiency .

Description

Technical field [0001] The present invention belongs to the mechanical design, experimental methods and technical field, in particular to a rolling bearing oil loss test device and method. Background [0002] As an important support part in the mechanical transmission mechanism, rolling bearings have an important impact on the dynamic characteristics, reliability and stability of the entire transmission system. In order to ensure safe and reliable operation of the bearings and minimize friction and wear, the bearings need to be lubricated. [0003] The oil loss caused by the churning oil caused by the stirring of the lubricating oil by the roller, cage and other structures during operation has become a problem that cannot be ignored to improve the efficiency of the bearing. At present, there are very few devices specifically designed to test the oil stirring loss of rolling bearings, and the application surface is narrow, and it is impossible to accurately extract the loss of oil...
