摘要： A hoisting and lowering driving engagement multi-row chain is disclosed, in which bending of the connecting pins in the chain is suppressed to avoid fatigue failure. Additionally, the load carrying balance in the chain width direction is improved, and contact vibrations and contact noises generated between the chain and the hoisting and lowering sprockets are suppressed. Endurance of the bush in the chain is thereby improved. Bending of connecting pins is avoided by press-fitting bushes, through which connecting pins pass, into intermediate tooth plates. This also improves load carrying balance widthwise. Contact noises and vibrations between the bushes and sprockets are suppressed by providing bushes with a separate sprocket engagement portion having a larger diameter than the press-fitting portion of the bushes.

摘要： An oilless chain is configured to connect alternately a pair of outer plates having two pins for coupling each other and a pair of inner plates, disposed adjacent to the pair of outer plates, having two bushings for coupling each other, by incorporating one of the pins into one of the bushings. After perfluoropolyether is impregnated into the bushings, the bushings are immersed in a lubricating oil composition prepared by blending perfluoropolyether with polytetrafluoroethylene. The polytetrafluoroethylene has a primary particle diameter adapted to the diameter of the pores of the bushings through which the lubricating oil composition flows.

摘要： The oil-free chain is obtained by connecting a pair of inner link plates which are connected by oil-impregnated bushings and a pair of outer link plates, which are connected by pins inserted into adjacent oil-impregnated bushings of adjacent inner link plates alternately. The oil-impregnated bushing is obtained by impregnating a bushing made of a metal sintered body with perfluoropolyether having a kinematic viscosity at 40° C. equal to or higher than 350 mm2/s. The bushing is impregnated with perfluoropolyether having a kinematic viscosity corresponding to the operating temperature of the oil-free chain.

摘要： Aspects of the invention provide a hoisting and lowering driving engagement multi-row chain in which the weight of the chain is balanced across the chain width direction so as to improve the load balance. This allows the weight of articles to be hoisted and lowered more stably hoisted and at higher positions, and results in an improvement of endurance of the chain, reduction of driving noise, miniaturization of the chain size, while the biasing or deflecting of intermediate tooth plates and inner tooth plates in the chain width direction is suppressed.
