Title:
ROTATION TRANSMISSION SHAFT UNIT, AND MOTOR, INVERTER TEST BENCH, AND EMC TEST EQUIPMENT DEVICE USING SAID SHAFT UNIT
Document Type and Number:
WIPO Patent Application WO/2023/022192
Kind Code:
A1
Abstract:
Provided is a rotation transmission shaft unit that is easy to install and that can effectively transmit rotation at high frequency and high torque. Also provided are a transmission device and a test device that use the shaft unit and transmit high torque and high rotation over a long span. A rotation transmission shaft unit that is easy to install and center and that can rotate at high torque and high speed is realized by providing bearings to both ends of a rigid cylinder and rotatably supporting, by using the bearings, a central shaft made of a fiber-reinforced resin. Stability of the axial position of the central shaft can be achieved simply by supporting the rigid cylinder of the shaft unit. The rotation transmission shaft unit, due to being a unit, is easily attached in and detached from an installation position and is easily centered with respect to the axis of a rotating machine. Because rotation can be transmitted over a long span, the speed of a motor test bench and an EMC test device can be increased.
