Abstract

The invention discloses a built-in conical surface pre-positioning permanent magnet synchronous coupler. The built-in conical surface pre-positioning permanent magnet synchronous coupler comprises aninner rotor and an outer rotor, wherein the inner rotor is provided with a first annular part, and the outer rotor comprises a second annular part and a third annular part which are coaxially arranged. The end surface of the second annular part is located in the third annular part. The first annular part is sleeved with the third annular part. The built-in conical surface pre-positioning permanentmagnet synchronous coupler further comprises a conical positioning sleeve mounted at the inner side wall of the first annular part or the outer side wall of the second annular part in a sliding manner; the conical positioning sleeve is provided with a first conical surface; the rotor without the conical positioning sleeve is provided with a second conical surface; and the first conical surface and the second conical surface are matched with each other to position the two rotors. According to the built-in conical surface pre-positioning permanent magnet synchronous coupler of the invention, the second annular part and the third annular part which have height difference are designed, so that the conical positioning sleeve can be reliably arranged in the inner rotor or the outer rotor; and the two conical surfaces are positioned at the inner side of an inner permanent magnet and are close to the axes of the rotors; and therefore, the conical positioning sleeve is small in size, light inweight and good in operation stability compared with the prior art.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a permanent magnet synchronous coupling with built-in conical surface pre-positioning. Background technique [0002] Since Mr. Li Guokun put forward the "Li's pull-push theory" in 1979, the synchronous permanent magnet coupling has obtained a theoretical basis. After the 1990s, the rapid development of rare earth permanent magnets has provided for the industrial production of synchronous permanent magnetic couplings. possible. Since then, synchronous permanent magnet couplings have been widely used in the chemical industry, mining, and power generation industries due to their advantages of high efficiency, non-contact, and shock isolation. But the fly in the ointment is that due to the strong magnetic force of the rare earth permanent magnet, during the installation process of the synchronous permanent magnet coupling, due to the effect of the magnetic force, it ...
