Abstract

The present disclosure provides a synchronous belt tensioning mechanism and a tensioning method, comprising: a motor, a synchronous pulley at the motor end, and a synchronous pulley at a load end, the synchronous pulley at the motor end is arranged on the output shaft of the motor, and the synchronous pulley at the motor end is connected to the load. There is a synchronous belt on the end synchronous pulley; the adjusting device is configured to adjust the distance between the synchronous pulley at the motor end and the synchronous pulley at the load end, so that the synchronous belt can obtain different tensioning forces; the calculation module calculates the transverse natural vibration frequency f of the synchronous belt m , meshing impact frequency f n , and determine the transverse natural frequency f m and meshing shock frequency f n Whether it is coincident, and feedback whether the tension needs to be adjusted. According to the theoretical basis of noise and vibration of the synchronous belt, the synchronous belt tensioning mechanism of the present disclosure determines the optimal tension force required by the synchronous belt by comparing the transverse natural vibration frequency and the meshing impact frequency of the synchronous belt, and automatically adjusts the tension within an appropriate range. The size of the force can avoid resonance noise and vibration, improve the performance of the synchronous belt, and increase the service life of the synchronous belt.

Description

technical field [0001] The disclosure belongs to the technical field of belt transmission, and in particular relates to a synchronous belt tensioning mechanism and a tensioning method. Background technique [0002] The synchronous belt resonance noise is the main component of the synchronous belt noise, and the synchronous belt resonance noise is mainly caused by the resonance caused by the coincidence of the synchronous belt meshing impact frequency and the synchronous belt transverse natural frequency. For the same synchronous belt, the synchronous belt meshing impact noise frequency depends on the synchronous belt speed, and the synchronous belt transverse natural frequency depends on the synchronous belt tension. Therefore, in order to avoid synchronous belt resonance, it is necessary to control and adjust the synchronous belt tensioner at any time. In related technologies, the tension adjustment is mainly manual pre-tightening based on experience, or the tension adjust...
