Abstract

1,246,251. Chains. VSESOJUZNY NAUCHNO - ISSLEDOVATELSKY I PROEKTNOTEKHNOLOGICHESKY INSTITUT UGOLNOGO MASHINOSTROENIA. 6 Jan., 1970, No. 675/70. Heading F2Q. In a chain comprising pairs of flat outer links 1 connected together by cylindrical pins 4, alternating with pairs of flat inner links 2 connected together by pins 3 having concave bearing surfaces to receive the pins 4, which extend through clearance holes in the inner links 2, at each hinge the angle α formed between the planes passing through the axis of the pin 4 and the edges of the concave bearing surface of the pin 3 is not less than 720/n degrees where n is the number of teeth of the smallest sprocket to be engaged by the chain. This is stated to prevent the pins 4 from rolling out of the concave bearing surfaces when the chain engages the smallest sprocket.
