A roller chain incorporates a plurality of rolling members between a roller and a bushing. A thrust bearing plate is provided between the end surfaces of the roller and inside surfaces of inner link plates. The outer diameter of the roller is smaller than the widths of the inner link plates and the outer link plates and the roller is accomodated in a projected area of the widths of the inner link plates and the outer link plates.

A drive chain suitable for use in a continuously variable transmission of a motor vehicle, the transmission having two pairs of spaced drive members about which the chain passes to transfer torque from one drive member to the other. The chain includes a plurality of link elements that include spaced, side-by-side plate links. The plate links include openings in which pairs of parallel rocker members are disposed for relative rocking movement of at least one rocker member about its longitudinal a...

A chain including chain pins 15, which connect an inner link plate and an outer link plate, are made of carburized or refined steel, and have the entire surface on which a large number of dimples 17 are provided which are formed through a primary shot peening performed at an arc height value of 0.35 to 0.8 mmA. Furthermore, dimples 21 with a size smaller than that of the dimples 17 are formed by applying a secondary shot peening performed at an arc height value smaller than that of a primary sho...

A chain is composed of multiple units each having two outer plates, two inner plates and a pin securely connecting the outer plates to the inner plates. The inner plate has two hollow cones oppositely formed on two sides of the inner plate and two tubes each formed on a corresponding one of the hollow cones. A space between an inner face of the hollow cone and the tube is defined to receive therein oil. A rivet hole is defined to align with a pin hole in the outer plate. Therefore, after the out...

The invention relates to a chain that consists of chain members with respective two inner flat links (1) that are parallel with respect to each other and two bushes (2) that are rigidly located between the inner flat links and that link two ends of said links each. The chain further comprises outer flat links (5) that interlink the chain members. Said outer flat links are parallel with respect to each other and hinge the ends of two adjacent chain members that face each other by rigidly linking ...

A chain comprises inner and outer links that articulate relative to one another on pins. The outer link having apertures which receive said pin ends in such a way that the links are easily assembled or dismantled. The pin ends have a retention portion that defines a flat and a bearing portion disposed between the retention portion and the inner link and defining a bearing surface for the outer link. The aperture in the outer link has an arcuate edge and a flat corresponding to that on the retent...

A drive chain comprises a plurality of inner links (1) interconnected by intermediate outer links and elongate pins (7) that are received in apertures in the inner and outer links. There is substantial clearance between the outer link and the corresponding inner links so as to permit flexion of the adjacent elongate pins in a direction substantially parallel to the length of the chain. The outer link may be in the form of a separate plate (6) or may be an integral part of the pins. In one embodi...

A chain comprises inner link plates that are each connected to an adjacent outer link plate by means of at least one pin that passes through overlapping portions of the respective links. Outboard of the inner link plates the pin supports a rotary bush with a radially extending flange. The bush in turn supports one end of an outer link plate and a roller. The outer link plate is an interference fit with the bush and the roller is rotatable relative thereto. In use the rollers are supported on a g...

A chain (CA) comprises a plurality of link units (10), each including a pair of link plates (11) and a connection member (12) placed between the link plates (11) at one end of each link unit (10). The link plates (11) of one link unit (10) are connected end to end with the link plates (11) of another link unit (10) by a connecting pin (13) in such a way that the link units (10) are angularly displaced by 90 degrees from one link unit (10) to another as viewed along an extending direction of the ...
