Diagnosis steps for electric spindle bearings (the most complete in the industry)!

In order to ensure that the electric spindle bearing can be used for a long time under the premise of good quality, it is necessary to carry out inspection and diagnosis of the bearing. (1) Inspection method under operating conditions: According to the inspection of the operating sound, vibration, and temperature of the bearing, inspection of the characteristics of the grease, and the replenishment or replacement time of the lubricating fluid. (2) Bearing appearance inspection: fully observe the bearings replaced by the equipment, check the condition of the dovetail guide rail surface and whether there is any damage, and whether it can be used again. The general diagnosis and management methods of electric spindle bearings are as follows: 1. Troubleshooting Check the operation of the bearing, including the noise, vibration, temperature, and lubrication of the bearing. 2. Bearing noise Use a sound detector to check the size and tone of the turning sound of the motorized spindle bearing in operation. If the bearing has a slight separation and other damage, there will be abnormal sound and irregular sound, which can be distinguished with a sound tester. 3. During the operation of the bearing vibration equipment, according to the vibration measurement of the motor bearing, it can be known whether the bearing is in an abnormal state. A special vibration measuring device (operating frequency resolver, etc.) measures the size of the vibration and deduces the details of the abnormality from the frequency distribution. Since the measured standard values ​​are different due to the use conditions of the bearing or the installation position of the sensor, etc., it is necessary to analyze the measured values ​​of each equipment in advance to clarify the judgment standard. It must be emphasized that in actual operation, abnormality can be expected to be found from the vibration symptoms of the running motor spindle bearings. The torque is accurate, in order to turn stable! 37 years of focus on the research and development, production, manufacturing and sales of electric spindle bearings!
