Abstract
An isolated transmission structure of gear vibration and noise composite inspection device for six-axes CNC includes an output shaft and a force input shaft of a gearbox to be inspected. The output shaft is driven by a power source. A magnetic coupling is set between the output shaft and the force input shaft of the gearbox. The magnetic coupling can be a radial type or an axial type coupling. As such, the output shaft will only transmit the power to the gearbox and will not transmit the vibration and noise. The inspection of vibration or noise of the gearbox can be made of a more accurate condition.
