Abstract
The utility model relates to a magnetic steel and particularly relates to a counterbore circular ring neodymium iron boron magnetic steel for a motor. The counterbore circular ring neodymium iron boron magnetic steel comprises a magnetic steel body, wherein a center position of the magnetic steel body is provided with a circular hole, a lower portion of the circular hole is provided with a counterbore, the counterbore and the circular hole are arranged in an integrated mode, a diameter at an upper portion of the counterbore is equal to a diameter of the circular hole, a cross section of the counterbore is in an isosceles trapezoid structure, the magnetic steel body is provided with a displacement emission sensor, a material of the magnetic steel body is the neodymium iron boron magnetic steel, and a surface of the magnetic steel body is coated with a nickel-plating layer. The neodymium iron boron magnetic steel for an oil field motor has a compact structure, improves product performance and prolongs service life.
Description
Technical field
The utility model is a kind of magnet steel, particularly a kind of counterbore annulus Nd-Fe-B magnet steel of motor.
Background technology
Magnet steel of the prior art, complex structure, and also fixed form is insecure, and result of use is not good, causes reduce its useful life.
Chinese patent 201020150678.5, discloses a kind of magnet, particularly a kind of samarium cobalt magnet with cambered surface that is mainly used in microwave communication technology, audio-visual technology, electrical engineering etc.Comprise magnet, described magnet pack is drawn together contour body and square body, and described contour body and square body are integrated, in described magnet, are provided with intermediate layer, and intermediate layer is coated with nickel coating.This structure relative complex, useful life is relatively low.
Summary of the invention
The utility model is mainly to solve the deficiencies in the prior art, compact conformation, and lifting assembly precision greatly promotes the counterbore annulus Nd-Fe-B magnet steel of a kind of motor of serviceability simultaneously.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of counterbore annulus Nd-Fe-B magnet steel of motor, comprise magnet steel, in the centre bit of described magnet steel, be provided with circular hole, the below of described circular hole is provided with the counterbore of mutually integrated distribution with it, the described diameter on counterbore top and the equal diameters of circular hole, the cross section of described counterbore is isosceles trapezoid shape, is provided with displacement emission sensor in described magnet steel, the material of described magnet steel is Nd-Fe-B magnet steel, and the surface of described magnet steel is covered with nickel coating.
Displacement emission sensor: when the displacement occurring in motor when magnet steel exceedes, displacement emission sensor is sent signal to control centre.
As preferably, the angle between the waist limit of the top of described counterbore and counterbore is 45 degree, and the diameter of described circular hole is 4.5mm, and the thickness of described magnet steel is 3.5mm, and the height of described counterbore is 1.5mm, and the diameter of described magnet steel is 15mm.
As preferably, the top of described circular hole and the top of magnet steel are same linearity and distribute, and the bottom of described counterbore and the bottom of magnet steel are same linearity distribution.
As preferably, the outer knuckle of described magnet steel is arc chord angle.
Therefore, the Nd-Fe-B magnet steel for oil field motor that the utility model provides, compact conformation, improving product performance, increases the service life.
