Embodiment Construction

[0021] figure 1 The roller chain shown in consists of alternating inner 2 and outer 3 links.

[0022] Each inner chain link 2 includes: two parallel inner chain plates 4 spaced apart from each other, two parallel connecting sleeves 5 arranged spaced apart from each other and connecting the inner chain plates 4 to each other, and two rollers 6 , in each case one of which is supported for rotation on the outer surface 7 of the connecting sleeve 5 . The connecting sleeve 5 is pressed into the opening 8 of the inner link plate 4 , wherein the face sides 9 of the connecting sleeve 5 protrude slightly beyond the inner link plate 4 . The length of the rollers 6 is slightly shorter than the internal distance between the two inner chain plates 4 .

[0023] Each outer chain link 3 includes two outer chain plates 10 arranged at a parallel distance to each other and two connecting pins 11 arranged at a parallel distance to each other. Each connecting pin 11 passes in each case through ...

Abstract

The present invention relates to a roller chain made of metal material, which has mutually alternating inner chain links and outer chain links and is respectively connected together by links, wherein the outer chain links comprise two parallel outer chain plates, which are formed by two parallel The connecting pins are connected together, while the inner links consist of two parallel inner link plates connected together by two parallel connecting sleeves, the connecting pins of the outer links passing through the connecting sleeves of the inner links in each case The outer surface of the connecting sleeve is equipped with rotatable rollers, wherein the ratio of the height of the outer link plate and the inner link plate to the outer diameter of the roller is greater than 1.4, and the average thickness of the inner link plate is the same as The dimensional ratio of the average thickness of the outer link plate is greater than 1.1.

Description

technical field [0001] The invention relates to a roller chain of metallic material, having inner and outer links alternating with each other and in each case connected to each other by links, wherein the outer links consist of two parallel outer chain plates, composed of two Two parallel connecting pins are connected together, while the inner link consists of two parallel inner link plates connected together by two parallel connecting sleeves, the connecting pins of the outer links pass through the inner links in each case The connecting sleeve is used to form a link, and a rotatable roller is arranged on the outer surface of the connecting sleeve. [0002] Examples of roller chains can be found in US 5382199 A, GB 2398852 A, EP 0257661 A and US 5799479 A. Background technique [0003] This type of roller chain is used very frequently, especially in applications where good acoustic properties of the chain are required. The rollers configured for rotation on the coupling b...
