Description
Technical field
The present invention relates to magnetic levitation bearing systems, and in particular to the protection bearing dress of ring gap in a kind of adjustable bearings
It sets.
Background technique
When magnetic levitation bearing system failure, rotor can lose bearing and drop on stator, high-speed rotating rotation meeting
System is caused to damage, it is therefore desirable to a kind of in emergency circumstances to provide the protection dress promptly supported for rotor in power-off etc.
It sets, but current traditional protective device only simply uses rolling bearing, in order to can work normally rotor, rotor and rolling
There are a gaps between bearing makes bearing damage so that rotor can cause very big impact and vibration to rolling bearing.Therefore
The novel protective device for eliminating bearing clearance plays the role of vital, but novel guarantor to the development of magnetic suspension bearing
Shield bearing also faces many problems, such as structure is complicated, can only can not be worked under power blackout situation using active control, so that newly
The reliability that type can eliminate gap protection device is not high.
Summary of the invention
In order to solve the problems, such as that protective device in the prior art can not be in automatic protection rotor under power blackout situation, the present invention
The protection bearing arrangement for proposing ring gap in a kind of adjustable bearings, solves above-mentioned technical problem.Technical solution of the present invention
It is as follows:
A kind of protection bearing arrangement of ring gap in adjustable bearings, comprising: rotor；Bearing block, the bearing block setting
In the end of the rotor；Bearing assembly, the bearing assembly is rotatably arranged in bearing block by first bearing, described
Bearing assembly gap is set in the periphery of the rotor, and the bearing assembly includes fulcrum bearing and the bearing that is mounted in fulcrum bearing
Part, the supporting member at least two, the supporting member are arranged close to the rotor and can radially transport relative to the fulcrum bearing
It is dynamic, opening is provided between the supporting member and the fulcrum bearing；Driving assembly, the driving component can be turned by second bearing
It is arranged in bearing block dynamicly, the driving component includes drive seat and the actuator that is movably arranged in drive seat, the drive
Moving part is arranged in a one-to-one correspondence with the supporting member, and the drive seat gap is set in the periphery of the rotor, the drive seat with
Gap between the rotor is less than the gap between the bearing assembly and the rotor；The rotor is by driving drive seat
Actuator rotation is rotated and then drives, when actuator turns to aperture position, the actuator is inserted under the action of the elastic member
Enter and pushes supporting member close in opening and support the rotor.
By the way that the structure of protection bearing arrangement is rationally arranged, in the case where having a power failure or accident occur, rotor is from original track
It falls off, since the gap between drive seat and rotor is less than the gap between supporting member and first bearing outer ring, rotor is first
It is contacted in drive seat, drives drive seat rotation, when drive seat drives actuator thereon to move to aperture position, actuator exists
Supporting member is pushed to be radially orientated rotor motion in insertion opening under the action of elastic component, until contacting with the periphery of rotor, at least
Two supporting members can be made rotor center place, no longer be contacted between rotor and drive seat, due to by supporting rotor
The presence of one bearing, rotor can drive bearing assembly rotation a period of time slowly to stop, play the good protection to rotor
Effect.
Further, the bearing assembly further includes dynamic clamping head and quiet clamping head, and the dynamic clamping head and quiet clamping head provides for the supporting member
Radially outer active force.
It further, further include mounting base, the mounting base is in bending, and one end of the mounting base extends to the branch
At least part of radially inner side of bearing member, the supporting member and the mounting base limit the dynamic clamping head and quiet clamping head jointly.
Further, the opening is wedge shaped, and the internal diameter of one end of close the driving component of the opening is greater than another
The internal diameter of one end.
Further, mounting hole is provided in the drive seat, the actuator is slidably arranged in the mounting hole, described
The axis of actuator is parallel to the axis of rotor, and elastic component is arranged on the actuator, and the elastic component is the actuator
It provides along its axis towards the active force of bearing assembly.
Further, the side of the separate bearing assembly of the drive seat is fixedly connected with driving baffle, the actuator
In the mounting hole across the baffle plate setting, it is extended with limited block on the outer wall of the actuator, the one of the elastic component
End is resisted against on the limited block, and the other end of the elastic component is resisted against on the baffle.
Further, one end towards bearing assembly of the actuator is spherical in shape or wedge-shaped, the actuator it is separate
Drive seat and setting finite place piece are stretched out in one end of bearing assembly.
It further, further include pull rod, the pull rod is located at side of the driving component far from the bearing assembly, institute
The one end of actuator far from the bearing assembly is stated to connect across the pull rod with the locating part.
Further, the bearing assembly and the setting of the driving component axially spaced-apart.
