Abstract
The invention discloses a demagnetization method for rotating along an inner circle or an outer circle of a heavy large bearing ring. The heavy large bearing ring is horizontally placed, the axial end face of the heavy large bearing ring is contacted with a bottom plate, an E-shaped iron core and a coil are reversely buckled on the bottom plate, the upper end face and two lateral surfaces of an enclosure are connected with handles respectively, the enclosure is fixed on two sides of the bottom plate through bolts, the enclosure is connected between two chute rods through fastening screws, the ends of the chute rods are connected with a framework, and a guide wheel is arranged in the framework. During working, the guide wheel rotates for a plurality of circles along the inner circle or the outer circle of the heavy large bearing ring through the handles on the enclosure, the current passes through the coil and the E-shaped iron core to generate an alternating magnetic field under the power-on condition, and the alternating magnetic field is acted on the heavy large bearing ring to form a flux loop to implement demagnetization of residual magnetism of the heavy large bearing ring. The heavy large bearing ring is kept static all the time during demagnetization so as to save hoisting and carrying and save manpower; and the method has good demagnetization effect and is simple and reliable in operation.
Description
Technical field
The invention belongs to bearing demagnetization technology field, refer more particularly to the interior circle of the great profile shaft bearing ring in a kind of edge or the demagnetizing method that cylindrical rotates.
Background technology
Great profile shaft holds and is used on large-size numerical control machine, metallurgical and mining equipment, the wind power plant more.The volume of (lasso or refer to the inner ring that great profile shaft holds, or refer to the outer ring that great profile shaft holds) is bigger because great profile shaft bearing ring, and size is also bigger, makes the unusual difficulty of carrying of great profile shaft bearing ring.
In the production and processing of great profile shaft bearing ring; Particularly in Grinding Process; Some manufacturing procedure usually adopts magnechuck absorption bearing to process; Process the back and on the inside and outside circle of bearing, produce very strong residual magnetism, the existence of residual magnetism can be adsorbed many grinding iron filings, to the detection and the certain influence of next process processing generation of bearing.After the existence of residual magnetism made bearing group dress up finished product, its precision can reduce, and also can reduce useful life.
Because the self structure characteristic of great profile shaft bearing ring; Can not erect after great profile shaft bearing ring machines and deposit; But flat pendulum deposits, in case its warpage and reduce each item precision, and (or claiming demagnetization) work that therefore needs the residual magnetism of counterweight large-scale bearing ring to demagnetize.
The demagnetizing method of medium and small bearing ring has been reported much; Basic principle adopts the iron core winding around of definite shape mostly and under the energising situation, bearing ring is implemented demagnetization (or claiming demagnetization) work; Bearing ring produces in the demagnetization process and moves comparatively speaking; And to the great profile shaft bearing ring that can not arbitrarily move (produce in the demagnetization process and move) or can only keep flat and the great profile shaft bearing ring that can not erect, its demagnetizing method does not also appear in the newspapers.
Summary of the invention
In order to address the above problem; The invention provides the interior circle of the great profile shaft bearing ring in a kind of edge or the demagnetizing method that cylindrical rotates; This demagnetizing method is demagnetizer that can rotate along the interior circle or the cylindrical of great profile shaft bearing ring of design earlier, demagnetizer is placed on the axial end of great profile shaft bearing ring, and demagnetizer rotates through the interior circle or the cylindrical of directive wheel along great profile shaft bearing ring; Can eliminate the residual magnetism of great profile shaft bearing ring effectively, uniformly; Facilitate for assembling finished product great profile shaft holds, hold and have higher running accuracy, prolong the useful life that great profile shaft holds to guarantee great profile shaft.
In order to realize the purpose of foregoing invention, the present invention adopts following technical scheme:
The demagnetizing method that the interior circle of the great profile shaft bearing ring in said edge or cylindrical rotate; Used the one group of coil that is disposed on E sections core and the E sections core; Characteristic of the present invention is: great profile shaft bearing ring horizontal is placed; The axial end of great profile shaft bearing ring contacts with base plate in the demagnetizer; The one group of coil that is disposed on E sections core and the E sections core is arranged at back-off on the base plate; The lead-out wire of coil is arranged on the terminal box in the casing outside, and the casing upper surface and the two sides that are case structure are connected with handle respectively, and casing is through being bolted to the base plate both sides; The both sides of casing are connected between two chute bars through trip bolt and can be along the interior elongated slot direction move left and right of two chute bars with distances between adjustment and the directive wheel; The end of two chute bars connects framework, and two directive wheels are set in the framework, and the handle through different parts on the casing during work makes directive wheel enclose or a few along the interior circle or the cylindrical rotation one of great profile shaft bearing ring; Between electric current under the energising situation is through coil and E sections core, produce alternating magnetic field; Action of alternating magnetic field forms flux circuit and demagnetizes with the residual magnetism of implementing the counterweight large-scale bearing ring on great profile shaft bearing ring, the demagnetization deenergization that finishes takes off the demagnetization work that demagnetizer is promptly accomplished a great profile shaft bearing ring, and said casing, base plate, handle, chute bar, framework, directive wheel, trip bolt, E sections core and coil are included in the demagnetizer.
Owing to adopted technical scheme as stated, the present invention has following superiority:
1, demagnetizer of the present invention can rotate along the interior circle or the cylindrical of great profile shaft bearing ring; Between electric current under the energising situation is through coil and E sections core, produce alternating magnetic field; Action of alternating magnetic field forms flux circuit and demagnetizes with the residual magnetism of implementing the counterweight large-scale bearing ring on great profile shaft bearing ring; Demagnetization effectiveness is good, and operation is simple and reliable.
2, demagnetizing method of the present invention can make great profile shaft bearing ring horizontal place, and that is to say that great profile shaft bearing ring remains transfixion in the demagnetization process, has saved the lifting and the carrying of counterweight large-scale bearing ring, has saved manual work.
