Reducer long-term use of noise is actually normal, I hope these problems can prevent further damage to the reducer as long as the user deals with it, of course, depends on what kind of reducer, what type of bearing is used. Here can only say that the normal is what problem, speed reducer under the speed of normal wear and tear is one of the largest reducer bearing, bearing ChangYun guild appear different degree of wear and wear will appear clearance, clearance is too large will appear different degrees of different acoustic vibration and impact, how to effectively reduce and reduce noise, will first check the bearing, As long as the bearing clearance problem is solved, the abnormal sound can be eliminated. Some clearance is too large, and the bearing must be replaced. Most of the broken tooth problems of the reducer are caused by loose parts in the reducer caused by too large bearing clearance, collectively known as the series shaft, and finally lead to the overall bad of the reducer. How to correctly adjust the clearance of bearings, with some theoretical knowledge to deal with the clearance problem is not very good, the best way to deal with the clearance of bearings is to enrich practical experience. To touch, listen, and then you can determine how much clearance, you need to add how much size of attachments, no more no clearance, clearance must be just right, accurate, modest, advised the users here best reducer manufacturers contact with us, we will guide your reducer manufacturers.
