Problems solved by technology

[0005] However, when the silent chain moves, various changes occur in the motion state of the silent chain. For example, the silent chain sometimes vibrates laterally in the chain width direction for the sprockets. If there is no meshing, there may be the following problems. The end surface of the guide plate and the tip of the sprocket teeth will have impact contact, resulting in friction loss and noise.

Embodiment

[0023] Below, according to Figure 1 ~ Figure 3 The silent chain 100 according to the first embodiment of the present invention will be described.

[0024] The silent chain 100 is configured as a timing chain installed in a timing system for an automobile engine, is wound around a plurality of sprockets S, and moves on a predetermined track. The silent chain transmission device is formed by the silent chain 100 and the sprocket S.

[0025] Such as figure 1 As shown, in the silent chain 100 , a plurality of guide rows 110 and a plurality of non-guide rows 140 are arranged alternately with half a pitch shifted in the chain length direction, and are flexibly connected by connecting pins 160 .

[0026] Such as figure 1 As shown, the guide row 110 is composed of a pair of left and right guide plates 120 arranged on both outer sides in the width direction of the chain, and a plurality of intermediate plates 130 arranged between the pair of left and right guide plates 120 . The n...

Abstract

A silent chain is provided, which can avoid impinging contact between guide plates and sprocket teeth and prevent wear loss and noise. A guide plate includes a main guide part formed on a side that engages with a sprocket, and an additional guide part formed on at least one of front and rear edges in the longitudinal direction of the chain. The additional guide part protrudes more in the longitudinal direction of the chain than an outer flank of a middle plate arranged in the same guide row and has a size that allows the additional guide part to overlap a sprocket tooth in the chain width direction when engaged with the sprocket S.

Description

technical field [0001] The invention relates to a silent chain, which alternately connects guide rows and non-guide rows in the length direction of the chain through connecting pins. The middle plate with a pair of pin holes in the front and back is formed, and the non-guiding row is formed by a plurality of inner plates with a pair of pin holes in the front and back. Background technique [0002] In the past, the following silent chain is known (for example, refer to Patent Document 1). The connecting pins inserted in the pin holes alternately connect the guide row and the non-guide row in the chain length direction. The guide plate and the middle plate with a pair of front and rear pin holes arranged between the left and right guide plates are composed of a plurality of inner plates with a front and rear pair of pin holes. [0003] In the conventional silent chain, the guide plate has a guide portion formed in the center of the chain length direction on the side where the...
