Embodiment Construction

[0023] will now refer to figure 1 and 2 Embodiments of the invention are described based on Examples 1 and 2.

[0024] figure 1 is a perspective view showing an example of the silent chain of the present invention. The silent chain 10 has three rows of inner webs ILP with meshing teeth and located in the engagement arrangement A and four rows of guide webs GLP in the guide arrangement B. In addition, the connecting pin Q is fixedly fitted in the pin hole of the guide connecting plate GLP, and the connecting pin Q is loosely fitted in the pin hole of the inner connecting plate ILP. figure 1 In order to show the internal structure of the silent chain, the two central guide plates GLP on the proximal side are cut away. should pay attention figure 1 represents an example of a silent chain with four rows of guide lugs and three rows of inner lugs, but if a silent chain with inner lugs and more guides than the inner lugs is used and the guide lugs are in the outermost row The ...

Abstract

To provide a silent chain which engages and slides smoothly over a long period of time without abnormal wear elongation even when extremely deteriorated lubricating oil having a high degree of oxidation is used. The silent chain comprises a guide link plate (GLP), a link pin (Q) fixedly mounted in a pin hole of said link plate and an inner link plate (ILP) with meshing teeth, said link pin being loosely fitted in an internal connection In the pin hole of the plate, it is characterized in that the inner connecting plate is made of a steel selected from heat-cured austenitic stainless steel, martensitic stainless steel, precipitation hardening steel, high carbon chromium bearing steel and alloy tool steel Matrix material.

Description

technical field [0001] The present invention relates to silent chains for transmission of power in vehicles, industrial machines and the like. Background technique [0002] In recent years, silent chains have been increasingly adopted in the field of timing chains or the like in automobiles under conditions of high speed and high load. [0003] The silent chain includes a guide link plate, an inner link plate having engaging teeth and a link pin each fixedly fitted into a pin hole formed in each guide link plate and loosely fitted into a pin hole formed in each inner link plate. in the pin hole on the The silent chain has various features, since each connecting plate is in oblique contact with the sprocket, the shock generated by the collision between the sprocket and the chain is alleviated and the noise level is reduced. [0004] In these conventional silent chains, chrome-molybdenum alloy steel or high-carbon steel containing 0.7-1.1% by weight has been used as the base...
