Title:
PROTECTIVE STRUCTURE FOR MAGNETIC BEARING AND MAGNETIC BEARING ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2018/032739
Kind Code:
A1
Abstract:
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 (31), sleeved on an optical shaft (10) and in a position corresponding to a magnetic bearing (20), a first gap being radially formed between the first radial bearing protective component (31) and the optical shaft (10); and a second radial bearing protective component (32), sleeved on the optical shaft (10) and in a position corresponding to the magnetic bearing (20), a second gap being radially formed between the second radial bearing protective component (32) and the optical shaft (10); the height value of a working gap being greater than the height value of the second gap, the height value of the second gap being greater than the height value of the first gap. The protective structure for the magnetic bearing and the magnetic bearing assembly effectively solve the problem, in the prior art, of lower security between the magnetic bearing and the optical shaft, since the protective structure for the magnetic bearing is prone to failure.
