Abstract
An object of the present invention is to provide a chain that reduces warping of connecting pins and prevents local wear in the bushings and connecting pins without causing an increase in the chain weight. Provided is a chain 10 including a plurality of inner links 20 formed by inner plates 30 and bushings 40, and a plurality of outer links 50 formed by outer plates 60 and connecting pins 70, wherein the plate height of each of the inner plates 30 as measured along an imaginary line L1 passing through the center of a bushing hole 31 and extending in a chain height direction is larger than a chain pitch P.
Claims3
A chain comprising:
- a plurality of inner links configured by coupling a pair of front and rear bushings to a pair of left and right inner plates;
- and
- a plurality of outer links configured by coupling a pair of front and rear connecting pins to a pair of left and right outer plates,
- the inner links and the outer links being alternately and pivotably coupled together in a longitudinal direction of the chain by inserting the connecting pins into the bushings,
- wherein a plate height of each of the inner plates as measured along an imaginary line passing through a center of a bushing hole in the inner plate and extending in a chain height direction is larger than a chain pitch.
