Abstract
An object of the present invention is to provide a chain and a chain transmission device capable of reducing sliding resistance of the chain to a guide lip portion and stably maintaining an oil film between the guide lip portion and an outer plate. Provided is a chain 20 wherein a plurality of link plates 40 and 60 include outer plates 60, each of the outer plates 60 has a pair of front and rear pin holes 61 into which connecting pins 50 are inserted, a guide-side end surface 62 that faces a traveling guide surface 81a side of a chain guide 80, and a contact convex portion 63 that protrudes from an outer surface of the outer plate 60, and the contact convex portion 63 is formed in an area between the pin holes 61 and the guide-side end surface 62 in a plate height direction.
Claims6
A chain comprising:
- a plurality of link plates;
- and
- connecting pins that pivotally connect the plurality of link plates,
- wherein the plurality of link plates include outer plates disposed on both outer sides in a chain width direction,
- wherein each of the outer plates has a pair of front and rear pin holes into which the connecting pins are inserted, a guide-side end surface that faces a traveling guide surface side of a chain guide, and a contact convex portion that protrudes from an outer surface of the outer plate,
- wherein the contact convex portion is formed in an area between the pin holes and the guide-side end surface in a plate height direction, and
- wherein the contact convex portion is formed into a belt-like shape that extends along a chain longitudinal direction of the chain.
