To provide a characteristic evaluation device that can properly evaluate a characteristic of a shaft coupling while considering a delay in a response of a motor, a characteristic evaluation device of a shaft coupling includes: a motor system including a drive motor, a rotation angle sensor configured to acquire a rotation angle of a drive shaft, and a motor control unit configured to control the drive motor based on a torque command; a rotational load connected to a driven shaft; and a processor configured to output the torque command and calculate a frequency response of a gain of an amplitude of an angular velocity ω of the rotation angle, wherein the processor is configured to calculate a characteristic of the shaft coupling based on a response characteristic of the motor system and the frequency response.

Power transmission coupling

A flexible shaft coupling demonstrates a high performance in transmitting torque and accommodating positional deviations, and is yet highly durable. A first elastomer member () having a relatively high rubber hardness is circumferentially interposed between a first claw () of a first shaft coupling member () and a second claw () of a second shaft coupling member (), and a second elastomer member () having a lower rubber hardness than the first elastomer member is interposed between a surface portion (end surface) () of the first shaft coupling member () and the second claw () and/or between a surface portion (end surface) () of the second shaft coupling member () and the first claw ().
