How to reduce the noise of the rubber timing belt on the machine tool?

There are some difficulties in the application of timing belts that manufacturers are unavoidable, but how to produce noise in the application must be noticed and dealt with immediately. The noise of the machine tool is an important point to evaluate the performance of the machine tool. In the operation of the machine tool, the noise of the main shaft is very large, and the main drive is generally transmitted by industrial timing belts. Therefore, the noise of the non-standard timing belt pulley that controls the high speed becomes the key factor to control the noise of the main shaft bearing. Generally there are the following solutions.

First of all, from the point of view of the sound source, when there is a lot of synchronous noise, if there is no good solution, generally a relatively simple and hard way can be used to immediately weaken its compressive strength in the sound source, although this Not a good solution, indeed see a quick fix in the short term.

Secondly, in response to the noise caused by the unbalanced centripetal force, the axis of the main shaft bearing and the motor can be adjusted in parallel to ensure that the precision of the double pulley rotation precision is g2.5, and the resulting noise can be effectively solved.

Third, when the timing belt and the industrial synchronous pulley are engaged with the pulley, the aerodynamic noise problem caused by the gas disturbance can also be solved through specific operations. You can adjust the belt tension of the timing belt to a suitable level for the machine, which will make the timing belt and the pulley better coordinate when they are engaged, thereby greatly reducing the noise. In addition, if this method still can not reduce the noise well or the degree of noise reduction can not satisfy oneself. It is also possible to set muffler grooves on the timing belt, and it is radial.
