Embodiment Construction

[0024] Preferred Modes for Carrying out the Invention

[0025] figure 1 It shows the Example of the roller chain of this invention. Its basic structure is the same as the above Figure 4 The roller chain shown is the same, and is constructed by alternately connecting a plurality of outer links 1 , 1 . . . and a plurality of inner links 2 , 2 . The outer link 1 has a structure in which both outer link plates 3 and 3 are connected in parallel with each other by two pins 4 and 4 . In addition, in the inner link 2, two inner link plates 5, 5 are connected in parallel with each other by two sleeves 6, 6, and the rollers 7, 7 are rotatably supported by the sleeves 6, 6. Therefore, in the roller chain, the pin 4 of the outer link 1 is inserted into the sleeve hole of the inner link 2 and is connected in a bendable manner.

Abstract

Provided is a roller chain such that both weight saving and sufficient strength are achieved. This roller chain is configured in such a way that the dimensions of two types of roller chains having different pitches are combined together. That is, the dimensions of the pitch of link plates (3, 5) are set to be equal to that of the outer link plates and the inner link plates of a larger-pitch roller chain, with the result that the overall longitudinal dimensions of the link plates (3, 5) are extended, and the dimensions of pins (4), bushings (6), and rollers (7) are set to be the same as those of the pins, bushings, and rollers that are components of a smaller-pitch roller chain.

Description

technical field [0001] The present invention relates to a roller chain that achieves both strength and weight reduction without changing the basic structure. Background technique [0002] Against the background of the recent increase in environmental problems, there is an increasing demand for weight reduction in various products. This requirement is no exception to the roller chain that is a constituent part of a motorcycle (two-wheeled motor vehicle). This roller chain is wound around a drive sprocket provided on the engine side and a driven sprocket provided on the rear wheel side in order to transmit the torque of the engine to the rear wheel. By reducing the weight of the roller chain, it is possible to Save resources and improve the transmission efficiency of power. [0003] However, in order to reduce the weight of the roller chain, it can be achieved by reducing the size of the chain (chain pitch), or by reducing the thickness of the link plate without changing the...
