Embodiment 1

[0031] Such as Figure 1-4 As shown, this embodiment provides an electromagnetic adsorption clamping protective bearing device, which includes a double-cone sleeve 2, a support assembly 3 and an electromagnetic adsorption assembly 4. The double-cone sleeve 2 is sleeved on the rotor 1 to support The components 3 are two groups, and the two groups of support components 3 are axially slidably assembled on the outer circumference of the double-cone sleeve 2, and the two groups of support components 3 are respectively arranged corresponding to the two conical surfaces 21 of the double-cone sleeve 2. The initial state Next, there is a gap between the two sets of support assemblies 3 and the two tapered surfaces 21, and there is also a gap between the two sets of support assemblies 3. The two sets of support assemblies 3 slide toward each other under the action of the electromagnetic adsorption assembly 4, and the two sets of support assemblies The components 3 respectively connect w...

Embodiment 2

[0041] Such as Figure 5-6 As shown, this embodiment is basically the same as Embodiment 1, the only difference is that the electromagnetic adsorption components 4 in this embodiment are divided into two groups and are respectively arranged on both sides of the two groups of supporting components 3, and the two groups of electromagnetic adsorption components 4 are driven The member 9 and the baffle 321 drive the supporting assembly 3 to slide axially.

[0042] Specifically, the two sets of support assemblies 3 are installed axially side by side on the inner peripheral surface of the frame 6 through the ball sleeves 7, without the need for an end cover. There is no need to set an extension between the two support positioning parts 32 of the two groups of support assemblies 3, and there are installation grooves on the opposite two surfaces of the two support positioning parts 32, and the two ends of the elastic member 5 are respectively placed in the two installation grooves In...

Abstract

The invention relates to a magnetic suspension bearing system, in particular to an electromagnetic adsorption clamping type protection bearing device. The device comprises a double-conical-surface sleeve, supporting assemblies and a electromagnetic adsorption assembly; the outer surface of the double-conical-surface sleeve is provided with two conical surfaces, and the double-conical-surface sleeve sleeves a rotor; the two supporting assemblies are assembled on the outer periphery of the double-conical-surface sleeve in an axial sliding mode, the two supporting assemblies are arranged corresponding to the two conical surfaces, and the inner surfaces, facing the double-conical-surface sleeve, of the supporting assemblies are conical surfaces matched with the corresponding conical surfaces of the sleeve; and the two supporting assemblies slide towards each other under the action of the electromagnetic adsorption assembly, the conical surfaces of the two supporting assemblies are connected with the two conical surfaces of the double-conical-surface sleeve, and the double-conical-surface sleeve is clamped. According to the device, the technical problems that in the prior art, under thecondition of power failure, overload and the like, falling of the rotor can cause impact and vibration to the magnetic suspension bearing system, so that the damage is caused are solved.

Description

technical field [0001] The invention relates to a magnetic suspension bearing system, in particular to an electromagnetic adsorption clamping protection bearing device. Background technique [0002] The magnetic suspension bearing system will lose the bearing capacity of the rotor in the case of power failure, overload, etc., so it is necessary to install a protective bearing device to provide temporary support for the rotor that loses support, so as to prevent the high-speed rotating rotor from falling on the stator and ensure the entire The safety of the magnetic levitation system. At present, the protective bearings used in the magnetic levitation system mostly adopt traditional rolling bearings, but in order to make the magnetic levitation system work normally, there is a fixed gap between the rotor and the inner ring of the rolling bearing. Therefore, when the rotor falls, since the gap between the rotor and the bearing cannot be eliminated, the bearing will be greatly...
