Description
Technical field
The utility model relates to a kind of draw-off gear of Model For The Bush-axle Type Parts.
Background technology
The current Model For The Bush-axle Type Parts for interference fit such as bearings, when field stripping, need special tooling, the general Three-claw pull-horse that uses pulls out Model For The Bush-axle Type Parts at present, and the middle part of arm-tie is provided with push rod, and push rod withstands the end of axle, the position of claw card is the outer ring of bearing, realize Model For The Bush-axle Type Parts pull-out by tightening push rod, this Three-claw pull-horse easily causes damage to the retainer of bearing, and load capacity is not strong, sometimes firmly excessive, cause claw fracture.
Particularly when changing double-fed wind power generator bearing, also must first pull down the collector ring being positioned at before bearing, collector ring needs again special draw-off gear, and the frock that need carry when maintenance is numerous and diverse.
Utility model content
The purpose of this utility model is to overcome above defect, provide a kind of load capacity strong, have certain versatility the draw-off gear of Model For The Bush-axle Type Parts.
The technical solution of the utility model is, a kind of draw-off gear of Model For The Bush-axle Type Parts, it comprises arm-tie, pull bar, also comprise interior draw ring, outer draw ring, double threaded screw, described interior draw ring is divided into two lobes, the inner circle of interior draw ring is provided with boss, lug boss position with treat that pulling shaft cover parts matches, the outer nose circle of described interior draw ring is provided with heavy stand along Model For The Bush-axle Type Parts axial direction to be removed, outer draw ring is placed in the heavy stand of interior draw ring external diameter end, arm-tie is placed in the end of axle, is provided with push rod in the centre of arm-tie, and stud links together interior draw ring, outer draw ring and arm-tie.
In order to be beneficial to the little little Model For The Bush-axle Type Parts of drawing Model For The Bush-axle Type Parts internal diameter more to be removed, also comprise backing plate, described backing plate is located between interior draw ring boss and little Model For The Bush-axle Type Parts, and described backing plate is divided into two lobes, together with interior draw ring is bolted on backing plate.
Useful technique effect of the present utility model is, the inner circle of interior draw ring is provided with boss, strengthened and the lifting surface area of Model For The Bush-axle Type Parts to be removed, so draw-off gear load capacity is strong, can not cause secondary injury to Model For The Bush-axle Type Parts to be removed.Between interior draw ring boss and other Model For The Bush-axle Type Parts, be provided with backing plate, thereby make this draw-off gear be applicable to the more Model For The Bush-axle Type Parts of minor diameter, applicability is wide, easy to carry, has reduced frock kind.
