Everyone in the reducer industry knows that the noise of the reducer, especially the worm gear reducer, is a headache for many reducer manufacturers.Reducing noise and ensuring stability during operation are the primary conditions for the quality of the reducer.Next, let's briefly understand how to reduce the noise of the reducer during the processing of the reducer.
The reasons for the high noise of the reducer are:
1. The bearing clearance is too large, causing the bearing to swing.
2. The gears are worn, and the gear meshing gap is too large, resulting in noise.
3. Internal bearing wear.Solve the problem from the source. The soft tooth surface of the old national standard reducer can not keep up with the pace of the times in terms of gear hardness and precision, but the main problem is that the factory inspection of the reducer has not been completed properly. The factory standard of the reducer noise is within 75 decibels. I think as long as the reducer manufacturer's factory inspection is completed, it can solve or at least reduce the noise in this area.
The noise of the reducer has a great influence on the smoothness of the workpiece, the contact accuracy of the gear, the motion accuracy of the gear and the assembly accuracy.In order to reduce the noise of the reducer, it is necessary to know the cause of the noise.The noise is caused by vibrations caused by variable forces acting on the bearings and housing during the operation of the internal gear.The main criterion for assessing the quality level of a spur gear reducer is its noise level.
With the internationalization of product standards, the country has imposed stricter restrictions on the noise value of the reducer, which requires research on the noise control of the reducer.
For how to reduce the noise of the reducer, many scholars at home and abroad regard the change of the meshing stiffness of the gear teeth as the main factor of the dynamic load, vibration and noise of the gear.To reduce noise, dynamic loads and speed fluctuations are minimized through refinements.Practice has proved that this method is an effective method.However, by
In this way, molding equipment is required during processing, which is usually impossible for most small and medium-sized factories.
After years of research, a gear design method is proposed, by optimizing the gear parameters, such as displacement coefficient, tooth height coefficient, pressure angle and center distance, to reduce or avoid the influence of meshing pitch circle, so that the meshing impact velocity is minimized, and The ratio of meshing impact velocity to meshing impact velocity is within a certain range of values.
To sum up, the noise of the reducer can be reduced by optimizing the gear parameters.
