Abstract
A bush (1, 19) for a bush chain (15), the inner surface (4) of which bush has a friction surface for a pin (12), wherein the inner surface (4) has two sections (4, 5, 21, 22), which lie opposite each other and extend in the longitudinal direction of the bush (1, 19) and are asymmetrically curved.
Claims16
A bush for a bush roller chain, comprising an inner surface that forms a friction surface for a pin, the inner surface has opposing first and second sections that extend in a longitudinal direction of the bush and are curved asymmetrically relative to each other, the first and second sections are curved convexly towards each other.
A bush, comprising a body having a through hole that defines an inner surface that forms a friction surface for a pin, the inner surface including opposing first and second curved sections that are asymmetric to one another and extend in a longitudinal direction of the hole that are connected by two additional opposing sections.
A bush roller chain, comprising a plurality of alternately arranged, interconnected, and pin-jointed inner and outer chain elements, said inner chain elements each comprising two spaced apart inner links interconnected by two bushes, and said outer chain elements each comprising two spaced apart outer links interconnected by pins that extend through the bushes of neighboring inner chain elements that are spaced apart by one of the outer chain elements, the bushes each including a body having a through hole that defines an inner surface that forms a friction surface for the pin, the inner surface including opposing first and second curved sections that are asymmetric to one another and extend in a longitudinal direction of the hole that are connected by two additional opposing sections.
