What are the causes of motor bearing noise? |
Motor in the process of work due to various reasons will produce noise, then at the time of production and life we have to distinguish between the causing reasons of noise, to facilitate our better grasp in the process of the actual operation of the motor fault reason, is one of the main motor bearing noise, so today I will introduce to crack down on simple what reason causing the motor bearing noise, hope to help everyone in the production and life. Bearing noise is an important quality assessment index of motor, but noise value is often exceeded in the noise test of motor factory test. We launched a special study on this phenomenon. How to solve this problem fundamentally, we first check the motor, replace the bearing, and still have the bearing noise when the motor is tested. We also find out the reasons for the production of the products, analyze the problems in the process of processing, and finally find out the key factors that affect the quality of the motor products. The reason is that in the case that the replacement of the bearing is not effective, we begin to review the parts processing size. Y2, 315, 110 kw - 4 p motor end cover product parts diagram, when measuring the bearing chamber found that do not conform to the requirements of the drawings, size error in the range is 0. 02 0. 05 mm, by the analysis of this kind of situation has a certain regularity (i.e., lateral and large lateral), appearance is bell shape. Because of the end cover of the bearing chamber manufacturing out-of-tolerance size, increasing the bearing housing and the coat fit clearance, so a coat in bearing indoor relative rotation, set, is what we usually call resulting in motor bearing noise. The size of the bearing chamber of the end cover is analyzed for further reasons and it is found that the batch end cover is processed by a foreign cooperative factory. The bearing room size does not change before and after the end cover fine car, and the end cover is removed from the rear bearing room. A slight increase in the measurement when the back is finished. After drilling the holes, the super difference is further enlarged, with a slight degree of 0.02 0.04mm and 0.05mm in severity.
