The described portable demagnetizer that is used for great profile shaft bearing ring, magnetic pole unit comprises E sections core and coil, and described E sections in-core disposes one group of coil, and the lead-out wire of coil is arranged on the terminal box of casing, and E sections core tips upside down on the base plate center.
The described portable demagnetizer that is used for great profile shaft bearing ring, casing is case structure, is connected with handle respectively at the upper end and the left and right sides end face of casing.
The described portable demagnetizer that is used for great profile shaft bearing ring, guiding mechanism comprises chute bar, framework and directive wheel, connect framework between two chute boom ends, be provided with elongated slot in each chute bar, the trip bolt of casing both sides configuration passes described elongated slot casing is fixed on chute bar both sides, is connected with two directive wheels in framework.
Owing to adopted technical scheme as described below, the utility model produces following effect:
1, the utility model is a kind of whole moving body demagnetizer, can relatively move around the radial end face of great profile shaft bearing ring and it be demagnetized, and has improved the running accuracy that great profile shaft holds, and has prolonged useful life.
When 2, using portable demagnetizer of the present utility model, bearing ring will keep flat.Two chute bars can be adjusted relative position between directive wheel and the casing by trip bolt, that is to say that two chute bars can make casing obtain telescopic adjustment, can make base plate cover on the axial end of bearing ring all the time according to the radius of curvature and the width of great profile shaft bearing ring like this, and two directive wheels are close to radially (circumference) end face at bearing ring all the time, pull handle makes portable demagnetizer rotate a circle around bearing ring radial outer end face or inner face, under the coil electricity situation, portable demagnetizer is implemented the demagnetization work to bearing ring.
But, make demagnetization work evenly, steadily clocklike carry out 3, by means of the translational speed and the direction of the portable demagnetizers of three handle Artificial Control that are provided with on the casing
4, simple in structure, the dependable performance of the utility model, processing ease, respond well.
