Problems solved by technology

Therefore this structure is not suitable for guides whose weight needs to be reduced
Moreover, material costs and production costs including casting have increased
Another problem is that the assembly is cumbersome, especially the operation of fixing the base A20 to the slide rail A10 through the hook A11 is cumbersome

Embodiment Construction

[0025] The movable guide shown in FIGS. 1-3 is a two-body structure, which includes a guide body 10 integrally molded from synthetic resin and a reinforcing plate 20 punched from a steel plate. The two-body structure in which the plate 20 reinforces its guide body 10 is obtained by inserting the reinforcing plate 20 into the guide body 10 in the direction of the arrow in FIG. 1 .

[0026] Its guide body 10 comprises a slide rail part 11 and a plate receiving part 12 at the back side of the slide rail part 11, wherein there is a sliding surface at the front part of the slide rail part 11, and a chain or other endless flexible transmission medium is on its sliding surface Swipe up. Since its plate receiving portion 12 is arranged vertically with respect to the sliding surface, its plate receiving portion 12 is generally vertical and extends in the longitudinal direction of the guide. Its plate receiving portion 12 includes a groove 12a opened longitudinally along the guide, and...

Abstract

A guide for a transmission chain, belt or the like includes a synthetic resin shoe having a sliding surface, a synthetic resin plate portion integrally molded on the back side of the shoe, and a plate which reinforces the guide body fitting into a longitudinal slot in the plate portion. The reinforcing plate is provided with punched windows, open in the direction of the plate thickness, and a through hole, aligned with a guide body mounting hole provided on an end portion of the guide. The total weight of the guide is reduced, and, even if the thermal expansion coefficients of the guide body and reinforcing plate differ, deformation of the guide and breakage of the guide can be prevented.

Description

technical field [0001] The invention relates to a sliding contact guide for a transmission using a jointless circulating flexible transmission medium. Examples relate to a guide in a chain drive, where the chain transmits power from the drive sprocket to the driven sprocket, or to a guide in a belt drive, where the belt transmits power from the drive pulley to the driven sprocket Driven pulley. Background technique [0002] Typically, chain or belt drives for timed regulation of rotational power in valves or other transmission mechanisms of internal combustion engines include a pivotally mounted movable sliding contact guide cooperating with a tensioner and a fixed sliding contact guide. Its movable and fixed guides are attached to the engine block or other drive mechanism by means of bolts, pins or similar mountings. Its guide provides suitable tension through sliding contact with the chain or belt, and prevents vibration of the chain or belt in the plane of its running t...
