CHAIN AND ITS LINK Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: chain comprises links having members for interaction with a sprocket for transmitting effort. The members are interconnected in series through pairs of mated convex and concave bearing surfaces. The surfaces are made on the bearing members of the links. The radius of curvature of concave surfaces is grater than the radius of curvature of convex surfaces. The convex and concave surfaces have guides made up as parts of the circumferences at sites of contact zones. The ratio of the radii is 0.1-0.9. The links of the chain are made up of clamps interconnected through connecting members made of a moulded constructional material. The connecting members are connected to the clamp surfaces. The bearing members for mating with adjacent links of the chain are arranged over the clamp ends. In engaging of the sprocket teeth with the link surfaces they rotate with respect to each other. As the links rotate the bearing surface of one of the mated links rolls up over the bearing surface of the other link. EFFECT: enhanced reliability. 14 cl, 3 dwg
