Problems solved by technology

[0005] However, in the above-mentioned method of assembling the power transmission chain, since a working process of joining both end portions of the link plates is required, a power transmission chain whose pin shape and the shape of the through hole of the link plate are relatively special , special parts are required for the connecting part, and the positions of the through holes of the link plate and the positions of the chain pins need to be coincident, etc., so complicated work is required
Therefore, it takes a lot of time and labor

Embodiment Construction

[0023] Hereinafter, one embodiment of the present invention will be described with reference to the drawings. As shown in Figure 2 (b), the power transmission chain 1 (hereinafter referred to as the chain) of the present embodiment is ring-shaped, and its composition includes: a plurality of chain link plates 2 made of metal (bearing steel, etc.); The link plate 2 is a pair of chain pins 3 made of a plurality of metals (such as bearing steel). This chain 1 is used in, for example, a continuously variable transmission of an automobile, and is used by being stretched between a driving pulley 20 and a driven pulley 30 as shown in FIG. 5 .

[0024] The chain link plate 2 is an elliptical plate material, and each piece is provided with two through holes 4 (first and second through holes), and in each of the through holes 4, two groups of chain links are respectively pressed pin 3. The link plates 2 are laminated in parallel in the thickness direction of the chain 1, and are conne...

Abstract

A method of manufacturing of power transmission chain (1) by interconnecting a plurality of link plates (2) with pins (3). Individual pin pairs (3) are arranged and temporarily fixed to places. The link plates (2) are sequentially stacked in layers by press-fitting respective through-holes (4) of the link plates (2) about the respective pin pairs (3), whereby the link plates (2) are interconnected to form a circular chain (an endless loop). Subsequently, the individual pin pairs (3) are released from the temporarily fixed state. Thus, the manufacture of the power transmission chain (1) is decreased in the number of operation steps, so that the chain may be assembled easily.

Description

technical field [0001] The present invention relates to a method of manufacturing a power transmission chain such as a continuously variable transmission chain used in vehicles and the like, and a chain pin jig used in the manufacturing method. Background technique [0002] As a power transmission chain used in a continuously variable transmission (CVT: Continuously Variable Transmission) of an automobile, for example, there is a ring-shaped power transmission chain installed between a driving pulley on the engine side and a driven pulley on the driving wheel side. transmission chain. In this continuously variable transmission, the sheave surface of each pulley is in contact with the chain pin end surface of the power transmission chain by means of boundary lubrication, thereby performing large power transmission, and continuously changing the respective groove widths of each pulley, thereby realizing infinitely variable transmission. variable speed. [0003] As the above-...
