Single-number chain

Abstract

The invention discloses a single-number chain which is a ring body formed by connecting a plurality of chain links in series. The front end of one of every two adjacent chain links is connected with the rear end of the other one of the two adjacent chain links in a free rotating manner, each chain link comprises chain pieces, protrusions fixed to the chain pieces and a pin shaft for fixing the twochain pieces and the two protrusions together, protrusion holes are formed in the protrusions, chain piece holes are formed in the chain pieces, and transmission of the single-number chain can be achieved by fixing the chain pieces and the protrusions together; the number of the chain links of the single-number chain is a single number, the single-number chain can be matched with a frame in any size, and the problems that as for an even-number chain, the requirement for the number exists, the number must be an even number, or the phenomenon that the chain is too long if one chain link is increased and the chain is too short if one chain link is decreased when the error value of a rack is too large sometimes are solved.

Description

technical field [0001] The invention relates to the field of sprocket transmission, in particular to a monocular chain. Background technique [0002] Bicycles are a traditional industry with a history of more than 100 years. Due to environmental protection and traffic problems, bicycles have once again become a favorite transportation and fitness tool for residents of countries in the world, especially developed countries. The focus of the world bicycle industry is shifting from traditional transportation to sports. In the United States, Europe, Japan and other developed countries, bicycles are a relatively common product for sports, fitness, leisure and entertainment. There is a huge demand for bicycles all over the world every year. Statistics from Japan's CYCLEPRESS show that in 2014, the global demand for bicycles remained at the level of 106 million units, and the annual transaction volume of bicycles was about 5 billion US dollars. [0003] Bicycles can be used as an ...

Problems solved by technology

[0007] Purpose of the invention: In order to solve the deficiencies of the prior art, the present invention provides a single-mesh chain, which overcomes the disadvantages of many consumables and heavy weight, and avoids the requirement that the number of meshes of a double-link chain must be an even number, otherwise sometimes the When the frame error value is too large, there will be a phenomenon that one more section is too long and one less section is too short.
