Problems solved by technology

Although the existing sprocket can meet the requirements of use to a certain extent, it is inevitable that there will be jamming and other phenomena when the chain meshes, which will lead to problems such as relatively large noise in the chain drive, and the chain is easy to fall off.

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0017] Such as figure 1 Shown is a schematic structural view of an embodiment of the integral low-noise flexible sprocket of the present invention. The integrated low-noise flexible sprocket of this embodiment includes a sprocket body 1 and a hub 2. The middle part of the outer peripheral wall of the sprocket body 1 is provided with a sprocket tooth 3, and the sprocket body 1 is equipped with sprocket teeth respectively. 3 The washer 10 on both sides and used to contact the chain plate of the chain. The washer 10 is made of wear-resistant rubber. The radially outward arc-shaped protrusions 12 are provided in one-to-one correspondence, which can effectively increase the service li...

Abstract

The invention discloses an integral low-noise flexible chain wheel. The integral low-noise flexible chain wheel comprises a chain wheel body and a hub, wherein chain wheel teeth are formed in the middle of the outer circumferential wall of the chain wheel body, washers which are respectively located on both sides of the chain wheel teeth and make contact with chain plates of chains sleeve the chain wheel body, and the washers are made of wear resistant rubber; a center through hole is formed in the center of the chain wheel body, involute internal splines are arranged in the center through hole, and involute external splines which are matched with the involute internal splines are arranged on the outer circumferential wall of the hub; fit clearances are formed between the involute internal splines and the involute external splines, and the fit clearances are filled with flexible elastic bodies which are used for connecting the chain wheel body and the hub into a whole; and fixed cover plates which are used for preventing the hub from axially moving are respectively arranged on the both sides of the chain wheel body.

Description

technical field [0001] The invention relates to a sprocket, in particular to an integral low-noise flexible sprocket. Background technique [0002] Chain drive is a transmission method that transmits the movement and power of the driving sprocket with special tooth shape to the driven sprocket with special tooth shape through the chain. Chain transmission has many advantages. Compared with belt transmission, there is no elastic sliding and slipping phenomenon, the average transmission ratio is accurate, the work is reliable, and the efficiency is high; the transmission power is large, the overload capacity is strong, and the transmission size is small under the same working conditions; the required tension The tightening force is small, and the pressure acting on the shaft is small; it can work in harsh environments such as high temperature, humidity, dust and pollution. The main disadvantages of chain transmission are: it can only be used for transmission between two paral...
