[0016] At the same time, it should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
[0017] Next, a detailed description of the specific embodiments of the present utility model will be given in conjunction with the drawings.
[0018] As Figure 1 shown, a magnetic levitation bearing with a wire coil 4 skeleton structure, the magnetic levitation bearing includes a bearing body 1 and a plurality of bearing cores 2 integrally arranged on the bearing body 1, the bearing cores 2 are located on the inner diameter of the bearing body 1 and extend towards the inside of the bearing body 1. Among them, there are 12 - 18 bearing cores 2, and all are made of silicon steel sheet materials.
[0019] Currently, when the wire coil 4 is installed on the magnetic levitation bearing, it is necessary to wind the wire coil 4 on the skeleton first and then fix the skeleton on the bearing core 2, which will affect the magnetic permeability of the bearing and reduce the drive power density.
[0020] In the magnetic levitation bearing of this patent, by removing the skeleton and wrapping the outer surfaces of the bearing body 1 and the bearing iron core 2 with insulating tape 3, the wire coil 4 is fixed to the bearing iron core 2 through the front plate 6, the rear plate 7 and the baffle plate 5. This can improve the magnetic permeability, reduce the iron loss and copper loss, enhance the operating efficiency, and increase the output power of the magnetic bearing.
[0021] Working principle: The thickness of the insulating tape 3 is thinner than that of the skeleton. The coil can be closer to the iron core, and the isolation gap between the winding wire coil 4 and the bearing iron core 2 is small. The fixed installation method of the front and rear plates 7 of the wire coil 4 plus the baffle plate 5 of the wire coil 4 obtains a better fastening fit. During operation, it is not easy to have electromagnetic sound due to the turbulence between the coils, saving copper wire and reducing costs.
[0022] Regarding the specific positional relationship of the above structure: The bearing iron core 2 provided with the insulating tape 3 is provided with a wire coil 4, a baffle plate 5, a front plate 6 and a rear plate 7. The front plate 6 is inserted at the connection between the bearing iron core 2 and the bearing body 1, and the rear plate 7 is inserted at one end of the bearing iron core 2 away from the bearing body 1. The wire coil 4 is wound around the bearing iron core 2 and is located between the front plate 6 and the rear plate 7. One end of the wire coil 4 abuts against the front plate 6, and the other end abuts against the rear plate 7. The baffle plate 5 is arranged on the rear plate 7 and is connected to an adjacent rear plate 7.
[0023] As Figure 1 shown, the magnetic levitation bearing further includes an insulating pressing plate 8 having the same shape and size as the bearing body 1 and the bearing iron core 2. The insulating pressing plate 8 is arranged on the front and back sides of the bearing body 1 and the bearing iron core 2 before the insulating tape 3 wraps the bearing body 1 and the bearing iron core 2, and the insulating tape 3 simultaneously wraps the bearing iron core 2 and the insulating pressing plate 8 on the bearing iron core 2.
[0024] Since there will be sharp edges at the corners of the bearing iron core 2, simply winding the insulating tape 3 will cause the insulating tape 3 to be damaged. By adding insulating pressing plates 8 on both sides, the above situation can be prevented.
[0025] To ensure the safe and normal operation of this structural patent, it is necessary to ensure that the width of the insulating tape 3 is greater than the width of the wire coil 4.
[0026] The above is the description of the embodiments of the present invention. Through the above description of the disclosed embodiments, those skilled in the art can implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel points disclosed herein.
