Power transmission coupling and power transmission apparatus

摘要

A power transmission coupling comprises a power transmission member having first and second ends. The first and second ends are respectively connected to ends of corresponding shafts through corresponding first and second sliding pairs. The first and second sliding pairs are different in sliding direction from each other. The power transmission member is made of a fiber-reinforced synthetic resin of a polymer alloy comprising polyamide MXD6 and polyphenylene ether, to which glass fibers are being blended.
