Problems solved by technology

[0004] In the chain described in this patent document 1, since the upper end surface of the flat plate that slides with the chain guide is formed in a straight line, the sliding area between the chain guide and the flat plate becomes large, so the sliding resistance when the chain moves becomes large. Friction loss increases, and when used as a chain in a timing drive system, for example, there is a problem that there is a lot of power loss in the car engine and fuel consumption deteriorates

Embodiment Construction

[0025] Hereinafter, the chain 10 which concerns on one Embodiment of this invention is demonstrated based on drawing.

[0026] The chain 10 of the present embodiment is configured as a timing chain for an automobile engine, such as figure 1 As shown, it is equipped with: a plurality of internal connectors formed by fixing the two ends of the front and rear pair of bushings 20 to the bushing holes of the left and right pair of inner plates 30; A plurality of external connecting parts formed by the pin holes of the external flat plate 50; and the roller 60 embedded by the bushing 20. By inserting the connecting pin 40 into the bush 20, the inner link and the outer link are alternately linked in the chain length direction so as to be bendable.

[0027] In this embodiment, the inner plate 30 is set to have a greater thickness in the height direction of the plate than the outer plate 50, and is configured so that only the inner plate 30 slides relative to the chain guide G, in ot...

Abstract

Provided is a chain that can reduce friction resistance between the running chain and a chain guide with a simple structure. The chain 10 is formed of a plurality of plates 30, 50 including sliding plates 30 that are slidably guided by a chain guide G, the plates being coupled together with connecting pins 40 such that the chain is bendable. The sliding plates 30 each include a guide-side end face 31, and the guide-side end face 31 includes a recessed section 32 formed by cutting away part of the guide-side end face 31, and a guide sliding section 33 located on a front side in a chain running direction of the recessed section 32. The recessed section 32 includes a negative pressure canceling surface 32a at a front end thereof in the chain running direction.

Description

technical field [0001] The present invention relates to a chain, which is provided with a sliding plate slidably guided by a chain guide. Background technique [0002] Generally, power transmission mechanisms such as automobiles and industrial machines, transportation machines, and the like are equipped with a transmission device that transmits power through a chain wound around a driving side sprocket and a driven side sprocket. For example, the engine of an automobile is equipped with a timing transmission system that transmits power through a chain that is wound around the crankshaft sprocket (drive side sprocket) and the camshaft sprocket (driven side sprocket). Make a slide guide. [0003] Conventionally, as a chain provided with a sliding flat plate slidably guided by a chain guide, there is known a chain in which an outer flat plate and an inner flat plate are formed by substantially oblong plates having parallel upper and lower end faces, and the outer and inner fla...
