Technical Field
The utility model relates to a single motor drive double-synchronous belt mechanism.
Background
Synchronous belt drive is meshing belt drive. The traditional large-span remote transmission mostly adopts V belt transmission or chain transmission, but the elastic sliding of the V belt transmission and the noise and trembling vibration in the chain transmission greatly influence the performance of mechanical equipment, so that the synchronous belt transmission is widely used in high-speed equipment, numerical control machines, robot industries, automobile industries and light textile industries.
The synchronous belt transmission consists of a synchronous belt with equidistant tooth shapes on the inner peripheral surface and wheels with corresponding inosculation. It combines the advantages of belt drive, chain drive and gear drive. When the power-driven wheel rotates, the belt teeth are meshed with the tooth grooves of the wheel to transmit power. The transmission synchronous belt has accurate transmission ratio, no slip, constant speed ratio, stable transmission, vibration absorption, low noise and wide transmission ratio range which can reach 1:10 generally.
According to the working scene of a belt wheel, the tension of the synchronous belt needs to be properly adjusted, if the tension is insufficient, the synchronous belt slips, so that the abrasion of the synchronous belt is increased, other capacities of losing transmission loads are realized, and the belt transmission loses efficacy due to transmission instability. If the tension of the synchronous belt is too large, the deformation is severe, which can reduce the service life of the synchronous belt. Therefore, it is necessary to periodically check and adjust the tension of the timing belt at the time of maintenance of the apparatus.
