Noise in machine tool performance occupies a very important indicator of modern numerical control machine tool main drive is given priority to with high torque arc synchronous belt transmission.

So how should under the condition of the line speed driving control the noise of the machine?

Reducing the noise of the machine is mainly from two aspects to reduce the noise of synchronous belt of the nc machine tool.

To think of some way to the first on the one hand, from the sound source.

Belt wheel itself due to its shape tolerance and position tolerance, turn two belts reincarnation, voice due to unbalanced centrifugal force.

1, when choosing synchronous belt wheel, should choose high quality, high precision synchronous belt wheel.

2, pretension of synchronous belt and flat belt, synchronous belt on the tooth meshing transmission power, so don't need a lot of prestressing tension, excessive tension will seriously affect the service life of the belt, have serious noise.

On the other hand, to find a way to from the noise transmission way. Caused by mesh belt and pulley, the disturbance of the gas to produce the aerodynamic noise.

Synchronous belt wheel circumference direction sound attenuation trough belt width is wider, airflow run route is longer, the greater the pressure change of gas also, thus the greater the noise.

So want to synchronous belt wheel and belt width narrow as far as possible, but the width of the synchronous belt have approximately proportional relationship with transfer of power, in order to meet the design power, pulley and the belt must have a certain width.
