Problems solved by technology

However, there is a problem that the mass of the inner link plate with a convex arc-shaped back is increased due to the convex arc-shaped portion, and the mass of the silent chain composed of several inner link plates also increases accordingly.

Embodiment Construction

[0034] Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 3 . 1 is a front view of an inner link plate, FIG. 2 is an explanatory view showing a contact state between an inner link plate and a brake shoe, and FIG. 3 is a perspective view of a part of a silent chain.

[0035] As shown in FIG. 3 , the inner chain plates 6 of the silent chain 1 having a pair of teeth 2 , a pair of pin holes 3 and a back surface 4 are respectively arranged in guide rows GL (with guide plates 8 column) and non-guided column JL (column without guide plate 8). In addition, a guide plate 8 having a pair of pin holes 7 is arranged on the two outermost sides of the guide row GL, and connecting pins 9 are inserted into each pin hole 3 of the inner link plate 6, and both ends of the connecting pin 9 are fitted and fixed on the guide rails. The pin hole 7 of the plate 8 is formed in a jointless shape, and the guide row GL and the non-guide row JL are relatively bendable. ...

Abstract

The aim of the invention is to provide a laminated chain which can reduce the contact area to reduce the frictional resistance and can reduce the frictional dissipation generated in power transmission and realize the chain lightening when the inner chain board sliding-contacts the brake shoe of the guiding component. A pair of teeth (2), a pair of pin holes (3) and the inner chain board at the back surface (4) which are comprised on the laminated chain (1) are respectively configured to guiding row GL and non-guiding JL, the connecting pin (9) is inserted into each pin hole of the inner chain board, and the two ends of the connecting pin (9) is formed with the mode that the two ends are inosculating-fixed into the pin hole (9) that guides the guiding board (8) at the utmost exterior part. The inner chain board (6) which is configured to the guiding row and the non-guiding row is formed with an arc shaped dent (5) at the back surface (4).

Description

technical field [0001] The present invention relates to a silent chain, which is used in a timing drive system of an internal combustion engine such as an automobile engine, and an oil pump drive, etc., and particularly relates to a silent chain which can reduce friction caused by sliding friction with guide members such as tension rods and guide rods. friction loss. Background technique [0002] In recent years, in response to the requirements of high load, high speed and easy maintenance, the silent chain is used for the timing drive of the automobile engine to replace the toothed belt that was often used in the past. [0003] The silent chain is a jointless chain, and the inner chain plates with a pair of teeth, a pair of pin holes and the back side of the silent chain are arranged in guide rows and non-lead rows respectively along the length direction of the chain, and will have A guide plate with a pair of pin holes is arranged on the two outermost sides of the above-m...
