Abstract: Provided are a chain component that has a simple surface treatment structure and can maintain good wear resistance over a long time, and a chain that includes the chain component and maintains good wear elongation resistance. The chain component of a power transmission chain for industrial use includes a chromium nitride layer formed on an outer side of a steel base material and containing more than 0 mass % but not more than 55 mass % iron. At least a surface of the chromium nitride layer that slides against other components is a rough surface with peaks and valleys.

Abstract: To provide a sprocket that reduces the influence of tension fluctuations concurrent with load torque variations, that suppresses noise and vibration, and that prevents an increase in tension fluctuations, noise, and vibration even when the chain tension is low and the load torque is small, or in regions where a chain and the sprocket engage without being affected by the tension. The sprocket has a plurality of teeth mating with the chain that are provided with an equal pitch therebetween, and that include teeth with different working pressure angles relative to the chain.

Abstract: The present invention aims at providing a chain with excellent wear resistance, which minimizes chain elongation, reduces vibration and noise, and improves drive efficiency. The chain according to the present invention includes at least a plurality of link plates and a plurality of pins as chain components. The pins and mutually sliding chain components sliding against the pins are formed with a hardened surface layer containing one of Cr carbide, Ti carbide, V carbide, Nb carbide, Cr nitride, Ti nitride, V nitride, and Nb nitride on part or all of respective sliding surfaces. In the case where the chain includes bushings as chain components and the bushings are the mutually sliding chain components, the bushings are formed with the hardened surface layer on part or all of their sliding surfaces.

IPC: F16H55/30
Abstract: Provided is a sprocket which suppresses generation of order sounds corresponding to cycles and prevents increase in tension fluctuations, noise, and vibrations caused by resonance while alleviating the influence of the tension fluctuations corresponding to load torque fluctuations and suppressing noise and vibrations. A plurality of teeth formed to engage with a chain are arranged to form a phase fluctuation pattern of a waveform having a phase which fluctuates between positive and negative sides, and the phase fluctuation pattern is set to have parts having different wavelengths.
