Abstract

The invention discloses a synchronous belt drive mechanism capable of avoiding resonance, which comprises a first belt wheel, a second belt wheel and a synchronizing belt for connecting the first belt wheel with the second belt wheel, wherein the first belt wheel is a positive-circular belt wheel, gear teeth of the second belt wheel are different from the length of a line of action of the synchronizing belt, the telescopic deformation of the synchronizing belt, caused by the difference of the length of the line of action, is within a deformation range of the synchronizing belt. The invention has the advantages of being capable of reducing resonance of the synchronizing belt, reducing shake of the synchronizing belt, and reducing transmission noise.

Description

technical field [0001] The invention relates to a synchronous belt transmission mechanism. Background technique [0002] Synchronous belt drive has been widely used because of its accurate transmission of motion. However, the synchronous belt has a certain impact vibration during operation, which not only produces noise, but also affects the transmission accuracy, thus limiting the application of synchronous belt transmission. When the impact excitation of the synchronous belt is the same as, close to or a multiple of the natural frequency of the synchronous belt, it will cause the synchronous belt to resonate, thereby aggravating the vibration of the synchronous belt and generating greater resonance noise. Contents of the invention [0003] In order to overcome the disadvantages of synchronous belts in the prior art that are prone to resonance, resulting in severe vibration of the synchronous belt and large resonance noise, the present invention provides a method that ca...
