Abstract
The present invention provides a protective structure for a magnetic bearing and a magnetic bearing assembly. The protective structure for a magnetic bearing comprises: a first radial bearing protective component, sleeved on a shaft and in a position corresponding to a magnetic bearing, a first gap being radially formed between the first radial bearing protective component and the shaft; and a second radial bearing protective component, sleeved on the shaft and in a position corresponding to the magnetic bearing, a second gap being radially formed between the second radial bearing protective component and the shaft; the height of a working gap being greater than the height of the second gap, the height of the second gap being greater than the height of the first gap. The protective structure for the magnetic bearing and the magnetic bearing assembly effectively solve the problem of lower security between a magnetic bearing and a shaft, since a protective structure for the magnetic bearing is prone to failure in the prior art.
