The invention discloses a kind of locking protection structure of magnetic suspension bearing and with its magnetic suspension bearing, the locking protection structure of magnetic suspension bearing includes: shell, is placed in the intracorporal connection ring of shell and stator core；Wherein, stator core is connected with shell and connection ring respectively；The internal perisporium of shell is equipped with multiple lug bosses, the internal perisporium interference fit of multiple lug bosses and shell.The present invention can make the junction of connection ring and shell there is interference fit with axial both direction radial, can give the enough safe clearances of magnetic suspension bearing, play locking protective effect, improve product reliability；The difference of hardness and shell cooling shrinkage stress of the two are compensated mainly by lug boss in assembling process, to reach adaptive assembly purpose, the precision dependence of assembly and processing is reduced, assembly difficulty can be reduced, improve production efficiency. |
