Problems solved by technology

In order to ensure energy transmission efficiency, the gap between the permanent magnet rotor and the conductor rotor is generally small, but if the permanent magnet rotor and the conductor rotor are displaced due to load or motor shaft shifting, friction may be formed and debris may fly out. In the first form, there will be safety hazards, and on the other hand, external debris will easily enter the gap and cause wear and tear.
For the second form, the conductor rotors on both sides are connected by bolts and fully sealed. However, in actual use, this structure is not conducive to heat dissipation of the equipment, especially when there is a large speed difference between the motor and the equipment. High heat will be generated on the transmission mechanism, which will reduce the magnetism of the magnetic steel, and is not conducive to the observation and maintenance inside the transmission mechanism

Abstract

The invention relates to a permanent magnet transmission mechanism which comprises a conductor rotor and a permanent magnet rotor. The conductor rotor comprises a pair of rotor plates which are fixedly connected through bolts, and the permanent magnet rotor is arranged between the rotor plates. The permanent magnet transmission mechanism is characterized in that each rotor plate comprises a substrate and a conductor disk arranged on the substrate, a shield is arranged on the periphery of each substrate, wind wings are arranged on each shield, each shield at least includes two arc-shaped shields, and the permanent magnet rotor comprises a permanent magnet disk and magnetic steel blocks arranged on two surfaces of the permanent magnet disk. The permanent magnet transmission mechanism has the advantages that safety can be ensured, and the permanent magnet transmission mechanism has a fine cooling effect.

Description

technical field [0001] The invention relates to the technical field of permanent magnet transmission, in particular to a permanent magnet transmission mechanism. Background technique [0002] At present, the permanent magnet coupling transmission mechanism has been widely used in industrial sites, such as fans and water pumps using permanent magnet transmission, especially for high-power loads. Due to the high reliability and low failure rate of the permanent magnet transmission mechanism, it can adapt to various harsh environments. In mining equipment, a transmission mechanism with a permanent magnet rotor in the middle and conductor rotors on both sides is mostly used. The conductor rotors on both sides are connected by bolts. Generally, there are two forms around the conductor rotor. One is that the conductor rotor is open around the periphery, and the other is The species is completely enclosed. In order to ensure energy transmission efficiency, the gap between the...
