摘要： In an endless silent chain composed of alternating guide link rows and joint link rows connected by connecting pins, each guide link row is composed of a stack of three, centrally located, link plates and two outer guide plates, and each joint link row is composed of two pairs of link plates in abutting, side-by-side relationship. The pairs of link plates of the joint link rows extend into the spaces between the guide plates and the centrally located stack of each of two adjacent guide link rows.

摘要： In a silent chain of the inner flank engagement and outer flank seating type, the link plate teeth are arranged so that their rearwardly facing inner flanks protrude slightly beyond the outer flank overlapping link plate teeth in a preceding row when the chain is straight and in tension. The rearwardly facing inner flank is composed of an arc-shaped engagement starting region adjacent the tip and a straight engagement guiding region extending toward the root.

摘要： The plates of transmission chain for an engine are formed with a guide-contacting configuration composed of spaced flat surfaces that come into sliding contact with a flat chain guide, and convex surfaces, continuous with and between the flat surfaces, for sliding contact with a convex chain guide. The convex surfaces are connected by a concave surface that, with the guide surface, forms an oil-retaining clearance. The radius of curvature of the convex curved surfaces of the plate preferably increases gradually from the location where they meet the flat surfaces toward the location where they meet the concave surface. The plates can have the same configuration on the side facing the inside of chain loop as on the side facing the outside of the chain loop.

摘要： In a roller chain having cylindrical pins rotatably fitting into bushings on which the rollers are disposed, a vanadium carbide layer formed on the cylindrical pin surfaces avoids abnormal wear elongation of the chain, and allows smooth articulation of the chain over a long period of time, even when the lubricating oil is in an extremely deteriorated condition due to oxidation.

摘要： In a chain transmission, the guide-contacting portions of inner and outer plates of a chain each comprise a pair of front and rear flat surfaces, an intermediate concave oil-retaining surface and convex connecting surfaces. The lengths of the flat surfaces are such that adjacent flat surfaces of overlapping inner and outer plates overlap even when the plates in contact with the portion of a convex guide surface having the smallest radius of curvature.

摘要： Connecting pins in a roller chain are chromized by a diffusion penetration treatment, that results in inner and outer chromium carbide layers on the steel base material. The inner layer contains Cr7C3, and the outermost layer, which is thinner than the inner layer, contains Cr23C6. The surface roughness of the outer layer is reduced by barrel polishing, without removal of all of the Cr23C6-containing layer.
摘要翻译：辊链中的连接销通过扩散渗透处理进行镀铬处理，这导致钢基材上的内部和外部碳化铬层。内层含有Cr 3 N 3 O 3，而比内层更薄的最外层含有Cr 23 C 13， 6 。外层的表面粗糙度通过滚筒抛光减少，而不去除所有的含Cr 23 C 6 C 6层。
