During the operation of the engraving machine, the main shaft bearing will emit noise. The bearings of different brands may have large or small noises. Check the cause and solve it reasonably. So what are the reasons that cause the noise of the engraving machine spindle bearing? The editor summarizes a few points for everyone: 1. Bearing friction Sometimes the main shaft bearing of the engraving machine will have noise because the bearing is not installed properly, the bearing cover is not properly covered, or the engraving machine is caused by the wear of the bearing cover during long-term operation. Spindle bearings are making noise. 2. The problem of bearing lubricating oil; When the bearing lubricating oil is insufficient or the engraving machine leaks oil, the quality of the lubricating oil is not good, or the running time is too long, the lubricating oil time is too long, which may cause excessive noise of the engraving machine spindle bearing. 3. Bearing damage or wear problem; When the bearing is used for too long or improperly used, it may cause damage to the bearing cage, the inner and outer rings of the bearing may be worn, and the balls will fall out, which will cause excessive noise of the bearing. How should we prevent the excessive noise of the engraving machine spindle bearing caused by some abnormal reasons? 1. When choosing a cage, choose a cage made of aluminum alloy, copper alloy, etc., which is not easy to damage. The inner and outer sleeves of the bearing cannot be mixed with other manufacturers, but only from the same manufacturer; 2. Regularly check the oil level of the bearing. Regularly check the bearing In terms of use, if the bearing wear is serious, it should be replaced in time, and the bearing oil should be checked regularly, and good quality bearing oil should be selected and filled. Only when the torque is accurate can the rotation be stable!
