This utility model is intended being achieved by the following technical solutions: this utility model by ring-type sintered NdFeB Magnet and Ring-shaped plastics shell forms, and ring-type sintered NdFeB magnet surface is ambrose alloy nickel coating, its outer circumference face and upper plane intersection For chamfering；Ring-shaped plastics shell includes housing and base plate, and housing is the most identical with the inside and outside footpath of base plate and thickness, injection mo(u)lding in advance, Hull outside periphery and upper plane intersection are also molded into a chamfering, complete with the chamfering outside ring-type sintered NdFeB Magnet Full laminating；Ring-type sintered NdFeB Magnet is positioned on ring-shaped plastics base plate, then with ring-shaped plastics housing by ring-type sintering neodymium Ferrum boron magnets is coated with, together with the above close contact of the bottom of ring-shaped plastics housing and ring-shaped plastics base plate good bond, Ring-type sintered NdFeB Magnet is fully sealed, forms a complete ring-type sintered NdFeB magnet assemblies.

Preferably 1: the external diameter of ring-type sintered NdFeB Magnet is 33.8-34.2mm, and internal diameter is 23.8- 24.1mm, height is 9.8-10.2mm；The external diameter of associated ring-shaped plastics housing and ring-shaped plastics base plate is 35.3- 35.7mm, internal diameter is 22.2-22.6mm, and height is 11.3-11.8mm.

Preferably 2: the external diameter of ring-type sintered NdFeB magnet assemblies is 36.8-37.2mm, and internal diameter is 21- 21.3mm, height is 12.8-13.2mm；The external diameter of associated ring-shaped plastics shell is 38.3-38.7mm, and internal diameter is 19.5- 19.8mm, height is 14.3-14.8mm.

In two schemes, ring-type sintered NdFeB Magnet outer circumference face is 1.4-1.6mm with the chamfering of upper plane intersection ×45°；Ring-shaped plastics hull outside periphery is 2.2-2.6mm × 45 ° with the chamfering of upper plane intersection, ring-shaped plastics housing Being 1.48-1.52mm with the thickness of ring-shaped plastics base plate, plastic material is POM.

Compared with prior art, owing to sintered NdFeB Magnet matrix outer has ambrose alloy nickel coating, whole ring-type sintering Ndfeb magnet is coated with ring-type POM plastic shell again so that it is have the most high temperature resistant, the performance of high humidity, have simultaneously intensity big, Rigidity height, good springiness, anticorrosive, the feature of anti-attrition excellent in abrasion resistance.

Detailed description of the invention

Combine accompanying drawing by the following examples this utility model is described in further detail.

Embodiment 1:

First, the surface of sintered NdFeB Magnet matrix 1 carrying out spraying plating, coating 3 is ambrose alloy nickel, selects POM plastic to make For covering material, it is 35.5mm that POM plastic is molded into external diameter respectively, and internal diameter is 20.9mm, and height is 11.5mm, plastic housing 5 The ring-type POM plastic housing 5 that wall thickness is 1.5mm and POM plastic base plate 7, then will have the sintered NdFeB of ambrose alloy nickel coating 3 Magnet matrix 1 close-packed arrays is placed on ring-shaped plastics base plate, forms ring-type sintered NdFeB magnet assemblies, ring-type sintering neodymium ferrum The external diameter of boron magnets assembly is 34mm, and internal diameter is 22.4mm, and height is 10mm.Circle outside ring-type sintered NdFeB magnet assemblies 4 All end faces are 1.5mm × 45 ° with the chamfering 2 of intersection above.Then the outside appeared in ring-type sintered NdFeB magnet assemblies All it is coated with ring-type POM plastic housing 5.The outer circumference end face of ring-type POM plastic housing 5 and the chamfering of upper plane intersection For 2.4mm × 45 °, fit completely with the chamfering of ring-type sintered NdFeB magnet assemblies.The bottom of ring-type POM plastic housing 5 with Ring-type sintered NdFeB magnet assemblies 4, is sealed by the above close contact of ring-type POM plastic base plate 7 good bond together In it (as shown in Figure 1 and Figure 2).Plastic complete after more ring-type sintered NdFeB magnet assemblies is magnetized.
