Embodiment 1

[0016] An assembly process of a novel Hy-Vo toothed chain, comprising the following process steps:

[0017] (1) Put the guide plate on the pin shaft so that it is located at the center of the pin shaft, and put a number of equal number of inner chain plates on both sides of the guide plate. The thickness ratio of the guide plate to the inner chain plate is 1:1.2, where the guide plate, the inner chain plate and the pin shaft all adopt clearance fit;

[0018] (2) After the inner chain plate is assembled in step (1), use a pressing machine to install the outer chain plate on both ends of the pin shaft, wherein the outer chain plate and the pin shaft adopt interference fit, and the assembly of the outer chain plate The specific method is: first heat the outer chain plate to 225°C, then place it on the end of the pin shaft on the pressing machine, use the pressure of the pressing machine to press it into the pin shaft and fix it, and then cool it naturally after pressing to room ...

Embodiment 2

[0023] An assembly process of a novel Hy-Vo toothed chain, comprising the following process steps:

[0024] (1) Put the guide plate on the pin shaft so that it is located at the center of the pin shaft, and put a number of equal number of inner chain plates on both sides of the guide plate. The thickness ratio of the guide plate to the inner chain plate is 1: 1.3, where the guide plate, the inner chain plate and the pin shaft all adopt clearance fit;

[0025] (2) After the inner chain plate is assembled in step (1), use a pressing machine to install the outer chain plate on both ends of the pin shaft, wherein the outer chain plate and the pin shaft adopt interference fit, and the assembly of the outer chain plate The specific method is: first heat the outer chain plate to 226°C, then place it on the end of the pin shaft on the pressing machine, use the pressure of the pressing machine to press it into the pin shaft and fix it, and then cool it naturally after pressing to room...

Embodiment 3

[0030] An assembly process of a novel Hy-Vo toothed chain, comprising the following process steps:

[0031] (1) Put the guide plate on the pin shaft so that it is located at the center of the pin shaft, and put a number of equal number of inner chain plates on both sides of the guide plate. The thickness ratio of the guide plate to the inner chain plate is 1: 1.4, where the guide plate, the inner chain plate and the pin shaft all adopt clearance fit;

[0032] (2) After the inner chain plate is assembled in step (1), use a pressing machine to install the outer chain plate on both ends of the pin shaft, wherein the outer chain plate and the pin shaft adopt interference fit, and the assembly of the outer chain plate The specific method is: first heat the outer chain plate to 248°C, then place it on the end of the pin shaft on the pressing machine, use the pressure of the pressing machine to press it into the pin shaft and fix it, and then cool it naturally after pressing to room...

Abstract

The invention discloses a novel Hy-Vo tooth-shaped chain assembly technology and relates to the technical field of tooth-shaped chain assembly. The novel Hy-Vo tooth-shaped chain assembly technology mainly comprises the assembly processes of a guide plate, inner chain plates, outer chain plates, pin shafts and clamp springs. The novel Hy-Vo tooth-shaped chain assembly technology is simple and high in efficiency, and an assembled Hy-Vo tooth-shaped chain is good in stability, high in firmness, good in abrasion resistance and long in service life.

Description

technical field [0001] The invention relates to the technical field of toothed chain assembly, in particular to a novel Hy-Vo toothed chain assembly process. Background technique [0002] Toothed chain is an important mechanical basic part. With the continuous development of high-speed chain transmission technology, the application of chain transmission has gradually extended from traditional low- and medium-speed transmission to high-speed transmission. In recent years, it has been used in many important hosts, such as hybrid It has been successfully applied in power automobile transmission system and automobile engine timing system. The transmission chain transmission system is a unique transmission form of hybrid electric vehicles. With the gradual expansion of the production of hybrid electric vehicles, the application of transmission chains will be more and more. Hy-Vo toothed chain has the double effect of variable pitch and internal-external compound meshing. Through...
