摘要： A transmission chain is composed of pairs of outer plates and pairs of inner plates. The plates of each pair are in opposed, spaced relation to each other. The pairs of inner plates and the pairs of outer plates are disposed in alternating, overlapping, relationship along the length of the chain, with each pair of inner plates extending in a first direction into a space between one pair of outer plates, and in a second direction, opposite to the first direction, into a space between another pair of outer plates. Connecting pins connect the alternating pairs of plates in articulating relationship. Each of the connecting pins is press-fit into holes in a pair of inner plates and fits rotatably in holes in a pair of outer plates. A guide extends into a space between the outer plates, guiding the chain by engagement with inwardly facing surfaces of the outer plates.

摘要： Provided are a sprocket and a chain transmission mechanism configured such that noise and vibrations caused by the elongation of the chain and also wear of parts are reduced, the decrease in the meshing strength of the chain and the sprocket is inhibited, and the chain service life is extended. The sprocket and chain transmission mechanism each have bottom land portion arcs of a predetermined radius and a predetermined angular range between a plurality of teeth to be meshed with the chain. The radius of each of the bottom land portion arcs satisfies the following relationship with the diameter of a roller or a bush of the meshing chain: Rb>0.505*φr+0.069*φr1/3 (where Rb is the bottom land portion arc radius, and φr is the diameter of the roller or the bush of the meshing chain).

摘要： A chain is provided, whose strength is increased and whose power loss is reduced as a result of reduced friction resistance between link units and link plates. A pair of link plates 160 are pivotally coupled to a link unit 101 in the chain 100. A pair of connecting pin portions 110 and a pair of plate portions 140 are inseparably joined at joint parts 150 to form one link unit 101. A stopper portion 123 is provided to the connecting pin portion 110 between a plate portion 140 and a link plate 160 adjacent each other in the width direction to restrict the link plate 160 from coming closer to the plate portion 140.
