Lubrication service mechanical music responsibility determination method microscope method: 3.1 Sealed anti-small performance: through the bearing in the same way to prevent the dust from entering the inner sound. Excitation test: the bearing is placed in a specific dust environment and carried out at a specified speed. After the test, the sound of the internal noise is judged by the real rotation performance. 3.2 The bearing performance can be judged without the need to push the hand to prevent the lubrication of the bearing cavity from leaking when the shaft is running.
The non-cleaning light: the test machine 1 is operated according to the specified speed and load, and the leakage is judged according to the actual situation.
3.3 Seal the pipe: the shaft does not meet the external risk of blood. Increase the loss degree higher than the opening degree. Temperature test: push and also make the net operation, determine the H function surface measured net and the environmental field difference test, 4 test preparation

4.2.1 The medium should be 240\particles of powder, with the same JRT1 as the current standard 4.2.2 The medium should be dried on the surface of the plate, and then cooled by force. Ministry of Machinery Industry 1997-14-15 approved

6.1 The test numbers should be recorded in Table A1, Table A and Table A5 in Appendix A respectively. 5
6. The auxiliary value of the receiving device and the sliding service type is not accepted. The test number outside the disk is 30 minutes. The temperature is reversed and the temperature is full. The temperature range is set for six hours. The record is required: according to the expected length of Appendix A2. Table A4 can be divided into one (3 days). When the receiving device fails due to a fault or the operator violates the test regulations, you should select the spare samples to make up for it. 6.4 The test results show that the system is abnormal, the sound is dong, and other conductors are present. The machine should be measured in time. 6.5 The test records must be accurate. The sample number should be consistent with the step installation position. 6.6
