Embodiment Construction

[0029] Such as Figure 1-11 As shown, a sprocket has many advantages such as low noise, good stability, overload protection, suitable for high torque transmission, small transmission fluctuation, etc., and has excellent comprehensive performance indicators. Compared with the traditional chain sprocket transmission combination, the basic structure of the present invention is equivalent to it, and also includes a driving sprocket 1, a driven sprocket 2 and a chain 3, etc., and the chain 3 is formed by connecting several chain links 4, usually A bobbin chain is adopted, and the chain 3 is wound on the gear teeth of the driving sprocket 1 and the driven sprocket 2 .

[0030] But the difference is that the driving sprocket 1 and the driven sprocket 2 of the present invention both include two wheel bodies 0 arranged side by side, adopt a double-row sprocket structure, and the number of the chains 3 is two, two The chains 3 are arranged side by side, and are correspondingly wound on...

Abstract

The invention relates to the field of transmission technology. The purpose is to provide a double-row sprocket with overload protection for high torque transmission, including a driving sprocket, a driven sprocket and a chain, the chain is composed of several chain links, and the chain is wound on the driving sprocket on the gear teeth of the sprocket and the driven sprocket; the driving sprocket and the driven sprocket both include two wheel bodies arranged side by side, the number of the chains is two, and the two chains are arranged side by side, and correspondingly wind around It is set on the gear teeth of the two groups of opposite wheels of the driving sprocket and the driven sprocket; the two chains are provided with an overload buffer zone, which is opposite to a chain link of the chain, and the chain corresponding to the overload buffer zone A section consists of an anterior segment and a posterior segment that are independent of each other. The invention can protect the chain from overload and prevent the chain from breaking and being damaged when the torque is too large.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a double row sprocket used for high torque transmission. Background technique [0002] Traditional mechanical transmission methods include gear transmission, belt transmission, worm gear transmission, screw nut auxiliary transmission, chain sprocket transmission, etc. Among them, chain sprocket transmission is a very common transmission method, which is widely used in transportation, lifting, etc. , and various modern automatic equipment. As the name suggests, the most basic unit of a chain sprocket transmission is usually a chain and two sprockets. The chain is wound on the two sprockets, and one of the two sprockets rotates actively and the other rotates drivenly to form a power output. . Chain sprocket transmission has the advantages of wide application range and simple structure, but it also has disadvantages such as small transmission torque, fluctuations i...
