Embodiment 1
[0040] A kind of rolling bearing churning loss test method based on the above-mentioned device, comprises the following steps:
[0041] S1: Install and debug each test device, close the bypass valve for through-lubrication in the test box, and open the bypass valve for oil injection lubrication, so as to switch the lubrication mode to oil injection lubrication;
[0042] S2: Start the constant temperature and constant pressure oil supply system to adjust the lubricating oil in the oil tank to the temperature to be tested;
[0043] S3: Start the power pump to send lubricating oil into the test box along the pipeline to pre-lubricate the bearings to be tested; at the same time, use the pressure measurement and controller to ensure that the pressure at the nozzle of each bearing to be tested is the same;
[0044] S4: Start the motor to make the main shaft reach the speed to be tested, and wait for the data returned by the speed torque sensor to show that the motor speed is stable;...
Embodiment 2
[0049] In this example, the oil churning loss of the rolling bearing in the through lubrication mode is tested, and the main test devices include figure 1 , figure 2 shown.
[0050] Specific steps:
[0051] S1: Install and debug each test device, close the bypass valve for oil injection lubrication in the test box, and open the bypass valve for through lubrication, so as to switch the lubrication mode to through lubrication;
[0052] S2: Start the constant temperature and constant pressure oil supply system to adjust the lubricating oil in the oil tank to the temperature to be tested;
[0053] S3: Start the power pump to inject lubricating oil into the test box along the pipeline to pre-lubricate the bearings to be tested; at the same time, the measurement and control system ensures that the flow into each bearing to be tested is the same;
[0054] S4: Start the motor to make the main shaft reach the speed to be tested. After the data transmitted by the speed torque sensor...

Abstract
The invention discloses a device and method for testing the oil stirring loss of a rolling bearing. A bearing seat used for installing a bearing to be tested is arranged in a test box body, an oil outlet of an oil inlet main pipeline in the test box body is used for providing lubricating oil for the bearing to be tested, and the oil outlet at the bottom of the test box body is used for realizing the cyclic utilization of the lubricating oil. An output shaft of the motor is connected with a main shaft used for installing the bearing to be tested, the output shaft of the motor is provided with a rotating speed and torque sensor used for collecting the rotating speed and torque of the main shaft, and the main shaft is in sealed connection with the side wall of the test box body. The oil inlet main pipeline is connected to a constant-temperature and constant-pressure oil supply system, and a main shaft system is used to detect the rotation torque of the bearing. Meanwhile, the lubricating oil in the test box body is used for lubricating the bearing, and the oil stirring loss of the bearing under different lubricating oil working conditions is achieved by adjusting the infiltration amount of the lubricating oil. According to the present invention, the structure is simple, the rapid detection of the oil stirring loss under the bearing working conditions can be accurately achieved through the sealed box body and the lubricating oil system, and the detection efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of mechanical design and experimental methods, and in particular relates to a testing device and method for churning loss of rolling bearings. Background technique [0002] Rolling bearings are important supporting parts in mechanical transmission mechanisms, and their performance has an important impact on the dynamic characteristics, reliability, and stability of the entire transmission system. In order to ensure the safe and reliable operation of the bearing and minimize friction and wear, it is necessary to lubricate the bearing. [0003] The churning loss caused by the agitation of lubricating oil by rollers, cages and other structures during operation has become a problem that cannot be ignored in improving bearing efficiency. At present, there are few devices specially used to test the oil churning loss of rolling bearings, and the applicable range is narrow, and it is impossible to accurately extrac...
