The present invention relates to the field of magnetic suspension bearing system, in particular to a gear transmission support and protection bearing device, which includes a bearing I arranged at the end of the rotor; a drive unit is gap-fitted on the outer periphery of the rotor, and the drive unit includes a rotating part and a linear part, and the rotating part Assembled by rotation, the end surface of the rotating part facing the straight part has a protrusion extending, and the straight part is provided with an arc-shaped groove with a gradually changing depth corresponding to the protrusion. The inner peripheral surface of the straight part is distributed with teeth. When the rotor loses stability and falls, the rotating The part rotates with the rotor, and the protrusion on the rotating part moves from the depth of the arc groove to the shallow part to push the linear part to move along the axis; the support unit includes at least three supports, and the gap between the supports is distributed on the outer periphery of the bearing I And meshed with the inner peripheral surface of the straight part, the straight part can drive the supporting part to rotate to eliminate the gap between the supporting part and the bearing I, so that the supporting part supports the rotor. The technical problems of slow response speed and poor protection effect of the protection bearing device in the prior art are solved.
Description
technical field [0001] The invention relates to the magnetic suspension bearing system in the field, in particular to a gear transmission support protection bearing device. Background technique [0002] The magnetic suspension bearing system will lose the bearing capacity of the rotor in the event of an accidental power failure, so it is necessary to install a protective bearing device to provide temporary support for the rotor to prevent the high-speed rotating rotor from falling on the stator and cause damage to the stator. The safety of the magnetic levitation system. At present, the protective bearings used in the magnetic suspension system mostly use complex external mechanical mechanisms. Due to the complexity of the mechanism and the uncertainty of the accident, when the magnetic suspension bearing system is unexpectedly powered off, there will be phenomena such as the protection mechanism being stuck, and the bearing will be affected by the rotor. Large shocks and v...
