Embodiment approach

[0044] In one embodiment of the present invention, among the three tooth profiles of the chain plate, the inner tooth profiles of the two teeth at both ends are concave-convex curves, the outer tooth profiles are straight lines, and the tooth profiles of the middle teeth are all straight lines.

[0045] In one embodiment of the present invention, the chain plate has a double pitch on the meshing line with the sprocket, and the difference between the hole center distance and twice the pitch of the sprocket meshing with it is approximately equal to 2P( 1-cos(π / Z)).

[0046] In one embodiment of the present invention, the two ends of the chain plate have two pin holes of different sizes and shapes, wherein the smaller pin hole has an interference fit with the special-shaped pin shaft, and the larger pin hole has an interference fit with the special-shaped pin shaft. The rolling engagement of the pin shaft and the effective profile of the pin shaft meshing is a curve that makes th...

Abstract

The invention relaters to a bi-pitch and variable-pitch tooth-shaped conveyer chain, belonging to a silence conveyer chain on a medium-low speed production line. The conveyer chain is combined by the means that a plurality of chain link units are connected with one another, wherein any one chain link comprises a chain plate, a guide plate, an external chain plate and a special-shaped pin shaft, each chain plate is provided with three tooth profiles and bi-pitches, and two ends of each chain plate are provided with a plurality of pin holes with different sizes and shapes. The phenomenon of machine blocking when a material is conveyed can be reduced, the self weight of the chain can be reduced, the polygon effect can be reduced, and the meshing impact, noise and attrition can be reduced, sothat the conveyer chain is stable in driving, the reliability of a conveyer is improved, and the service life of the conveyer is prolonged.

Description

technical field [0001] The invention belongs to a conveyor chain, in particular to a silent conveyor chain suitable for medium and low speed production lines. Background technique [0002] In machinery manufacturing, agricultural machinery, metallurgy, chemical industry, textile, transportation, building materials, post and telecommunications, commerce and other departments, chain drive is widely used to transport workpieces, articles and materials. The conveying device includes a roller chain conveying device and a toothed chain conveying device. [0003] With the development of science and technology, the requirements for working efficiency and working environment in engineering are getting higher and higher. It is not uncommon for the inner width of the inner link of the chain to fall into the conveying device and cause the machine to be stuck, which not only reduces the service life and working efficiency of the conveying device, but also causes the line to stop due to ...
