Problems solved by technology
[0004] In the prior art, the connection between the coupling and the shaft is a hard connection, that is, the coupling and the shaft are in contact, so that there will be friction between them, which is easy to generate noise, and after a long time of use, it is very likely to The two shafts are not concentric and affect the normal operation of the two shafts, which in turn affects the service life of the motor
In particular, the two shafts in the magnetic suspension centrifugal blower or air suspension centrifugal blower must be concentric, otherwise it will directly cause the magnetic suspension centrifugal blower or air suspension centrifugal blower to not work normally, and even damage the magnetic suspension centrifugal blower and air suspension centrifugal blower

Embodiment Construction
[0022] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.
[0023] See Figure 1-6 As shown, it is a high-speed non-contact magnetic levitation coupling for a suspension blower, which includes a coupling body 1 and a first shaft body 2 and a second shaft body that are sleeved on both sides of the coupling body 1 and can rotate synchronously. Two shafts 3, a plurality of magnets are arranged at the connection between the first shaft 2 and the main body of the coupling 1, and the repulsive magnetic force formed by the opposite poles of the magnets makes the first shaft 2 and the coupling A gap is formed between the main bodies 1; a plurality of magnets are arranged at the junction between the second shaft body 3 and the coupling main body 1, and the first shaft body 2 and the A gap is formed between the coupling bodies 1 . In the present invention, a plurality of magnets are arranged at the joint between th...

The invention discloses a high-speed non-contact magnetic suspension coupling for a suspension blower. The high-speed non-contact magnetic suspension coupling comprises a coupling main body, and a first shaft body and a second shaft body which respectively sleeve two sides of the coupling main body, wherein a plurality of magnets are arranged at the joint of the first shaft body and the coupling main body, and a gap is formed between the first shaft body and the coupling main body through repulsive magnetic force formed by opposite like poles of the magnets; and a plurality of magnets are arranged at the joint of the second shaft body and the coupling main body, and a gap is formed between the second shaft body and the coupling main body through repulsive magnetic force formed by opposite like poles of the magnets. The coupling main body and the first shaft body as well as the coupling main body and the second shaft body are connected in a non-contact mode, so that friction and noise are basically not generated between the coupling main body and the first shaft body as well as between the coupling main body and the second shaft body, and even after long-time use, the phenomenon that normal work of the two shafts is affected due to the fact that the two shafts are not concentric can be avoided, and further, the service life of a motor is guaranteed.
Description
Technical field: [0001] The invention relates to the technical field of couplings, in particular to a high-speed non-contact magnetic suspension coupling for a suspension blower. Background technique: [0002] Coupling, also known as coupling, is a mechanical component used to firmly connect the driving shaft and driven shaft in different mechanisms to rotate together and transmit motion and torque. It does not disengage under normal conditions. device. Sometimes it is also used to connect shafts and other parts (such as gears, pulleys, etc.). [0003] Couplings are frequently used components in the power transmission process of mechanical systems, and are widely used in petrochemical, power industry, mining and shipping, aerospace, steel industry, papermaking and other industries. With the continuous development of science and technology, the application field of couplings has been continuously expanded, and the technology has also been continuously developed, and new pro...
