Problems solved by technology

[0003] At this stage, NdFeB magnets need to be realized due to work requirements when NdFeB magnets are used. Long-term movement is easy to cause damage to NdFeB magnets, affecting the magnetic properties of NdFeB magnets, making them unable to complete work requirements, and causing waste of resources. , so we propose a NdFeB magnet with better wear resistance to solve this problem

Abstract

The invention discloses a neodymium iron boron magnet with good wear resistance. The magnet is provided with a positioning block, and a placement hole is formed in the positioning block. Symmetrical positioning plates are arranged in the placement hole. Fixing grooves which are arranged at equal intervals are formed in the upper surface of the positioning plate. Balls are arranged in the fixing grooves in a sleeving manner, and a neodymium iron boron magnet is arranged in the placement hole in a sleeving manner. Symmetrical cavities are formed in the positioning block, and moving plates are arranged in the cavities. Push rods are fixedly connected to the side faces, away from each other, of the moving plates, and penetrating pipes are fixedly inlaid in the upper surface of the positioningblock and the bottom face of the positioning block, and the ends, away from the moving plates, of the push rods penetrate through the penetrating pipes and extend out of the penetrating pipes. The magnet is reasonable in design structure, can avoid the backflow phenomenon of lubricating oil, avoids the waste of the lubricating oil, further reduces the friction between the ball and the magnet, improves the wear-resisting effect, and prolongs the service life.

Description

technical field [0001] The invention relates to the technical field of neodymium-iron-boron magnets, in particular to a neodymium-iron-boron magnet with good wear resistance. Background technique [0002] NdFeB magnets can be divided into bonded NdFeB magnets and sintered NdFeB magnets. Bonding is actually injection molding, while sintering is vacuumized and formed by high temperature heating. The permanent magnet with the strongest magnetic force is expected to have no magnetic material to replace NdFeB magnets in the next two decades. The main raw materials for the production of NdFeB magnets include rare earth metal neodymium, rare earth metal praseodymium, pure iron, aluminum, Ferro-boron alloy and other rare earth raw materials. [0003] At this stage, NdFeB magnets need to be realized due to work requirements when NdFeB magnets are used. Long-term movement is easy to cause damage to NdFeB magnets, affecting the magnetic properties of NdFeB magnets, making them unable ...
