Embodiment Construction

[0008] The present invention will be further described below in conjunction with the accompanying drawings: the bearing adopts NdFeB to make ring-shaped closed magnets of the same level as the contact surface of the inner and outer rings, so that the inner and outer rings repel each other, that is, the inner ring contact surface and the outer ring contact surface are made With the same magnetic pole, the inner surface of the inner ring and the outer surface of the outer ring are made into another magnetic pole. There are also multiple fixed bayonets on both sides of the inner ring, which are made of NdFeB, and are connected to the outer surface of the outer ring. Similarly, the outer edge of the bayonet is stuck on the outer surface of the outer ring, and it is fixed by the method of homopolar repulsion.

[0009] Applying the present invention to a mechanical system utilizes the principle of homopolar repulsion of magnetic materials, and applies it to bearings, so that the inne...

Abstract

The invention provides a magnetic suspension bearing comprising an inner ring, an outer ring and a retainer, wherein a annular closed magnet is made of neodymium iron boron to form the mutual repulsion between the inner ring and the outer ring, the contact faces of annular closed magnet and the inner ring and the outer ring are homopolar, a plurality of fixed bayonets are also arranged on both sides of the inner ring, are made of magnetic metal and have the same magnetic poles with the outer surface of the outer ring, and the outer edges of the bayonets are clamped on the outer surface of the outer ring and fix the outer ring. The magnetic suspension bearing has the advantages that by utilizing the principle of homopolar repulsion of a magnetic material, the magnetic material is applied to the bearing so that the inner ring and the outer ring of the bearing generate mutual repulsion to generate the function of suspension, and therefore, the magnetic suspension bearing greatly reduces the contact rolling friction force between members and enhances the rotating speed.

Description

technical field [0001] The invention relates to a bearing, in particular to a magnetic suspension bearing. Background technique [0002] Bearings are fixed parts in machinery. When other parts move relative to each other on the shaft, the parts used to maintain the center position of the shaft and control the movement are called bearings. [0003] In terms of its function, it should be a support, that is, it is used to support the shaft literally, but this is only part of its function. The essence of support is to be able to bear radial loads. It can also be understood that it is used to fix the shaft. It is to fix the shaft so that it can only achieve rotation, while controlling its axial and radial movement. The consequence of a motor without bearings is that it cannot work at all. Because the shaft may move in any direction, and the motor is required to only rotate when it is working. Theoretically speaking, it is impossible to achieve the function of transmission. N...
