Self-adaptation tensioner sprocket

Abstract

The invention discloses a self-adaptation tensioner sprocket. The self-adaptation tensioner sprocket is used for solving the technical problems that in the prior art, a sprocket mechanism does not have the self-adaptation function, certain radial force to sprocket hobbing teeth constantly cannot be effectively ensured, the sprocket cannot independently solve impact and vibration until a chain pitch is increased, and tooth skipping is caused. The sprocket specifically comprises two sets of sprocket side plates, a middle wheel is mounted between two sets of sprocket side plates, multiple rotatable sprocket hobbing teeth are evenly arranged in the radial direction of the middle wheel and are elastically connected with the middle wheel, any one sprocket hobbing tooth can generate elastic force, the sprocket hobbing teeth move in the preset direction under the effect of elastic force, and make contact with corresponding two engaging teeth, a tooth-shaped chain is tensioned, the self-adaptation tensioner sprocket has the self-adaptation function, the impact and vibration caused during chain and sprocket engaging can be effectively reduced, and the probability of occurrence of the skipping phenomenon is reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission equipment, in particular to an adaptive tensioning sprocket. Background technique [0002] Under the current trend, mechanical transmission equipment is widely used in industrial production. Among them, take the chain transmission as an example. The chain transmission is a kind of flexible transmission, which relies on the meshing of the sprocket teeth and the chain link to transmit motion and power. The specific characteristics are compact structure, high reliability, and suitable for various industrial work The environmental requirements are low, especially for mechanical equipment with a large center distance. Therefore, chain drives are widely used in automobiles, motorcycles, construction machinery and some conveying devices. [0003] In the prior art, due to wear and tear of the chain, the pitch of the chain will increase. At this time, the meshing of the chain and the sproc...
