Description
Technical field
The utility model embodiment relates to a kind of bearing extractor, is specifically related to a kind of bearing extractor of dismantling indivisible bearing.
Background technology
In flight-line maintenance industry, often need to dismantle bearing.Part bearing (such as thrust bearing etc.), inner ring, outer ring and ball three parts are disassembled, dismounting more for convenience, is used the common in the market horse (drawing horse is the extracting tool that bearing and axle are separated) of drawing inner ring can be disassembled.But such as, for indivisible bearing (deep groove ball bearing etc.), major part draws horse to be difficult to be anchored on inner ring, if dismantle bearing by the mode of drawing outer ring, tend to bearing to cause the destruction of unrepairable, cannot use by secondary, especially for the comparatively expensive bearing of the price such as import, precision, affect larger.
Patent CN201120553594.0, a kind of bearing extractor is disclosed, it comprises: an abutment means, comprise at least two push pieces and a branch of circle, those push pieces are mutually against being also arranged as circlewise tubulose, define the lateral surface of a tubulose and the medial surface of a tubulose, respectively this push piece is formed with a top of radially protruding, arrange circlewise along this lateral surface those tops, this bundle snare is located at those push pieces, this bundle circle has elasticity, make those push pieces have to the central beam of this lateral surface close and mutually against trend; One fore-set, its outer peripheral face has a large footpath section, a path Duan Yuyi cascaded surface, and the diameter of this path section is greater than the diameter of this medial surface, and this path section is removably inserted in this medial surface, makes those push pieces by the radially outwards pushing and pressing of this path section.The advantage of this bearing is that structure simplifies to be beneficial to and carries, but this bearing extractor is five go-devil bearings tool special for dismounting, does not possess versatility.
Patent 201120248946.1 discloses a kind of hydraulic tool of dismantling deep groove ball bearings in permanent magnet motor, comprise the power transmission that produces the cylinder device of power and cylinder device the is produced axis of guide to magneto rotating shaft, the rotating shaft of the axis of guide and magneto is fixed, hydraulic tool also includes the pulling claw for the deep groove ball bearing that is installed, pulling claw is fixed by pulling claw seat and cylinder device, and pulling claw seat is pressed in permanent magnet machine rotor end supporting cylinder system.But this bearing extractor structure is comparatively complicated, is mainly made up of hydraulic system and pulling claw two large divisions mechanism, and part is more, installs and uses inconvenience, and meanwhile, the pulling claw spacing in this patent is non-adjustable, can only dismantles and formulate big or small bearing; And pulling claw is still buckled on bearing outer ring, in dismounting bearing process, can cause infringement to a certain degree to bearing arrangement.
Patent 200620032271.6 discloses a kind of thin wall zanjon ball bearing removing device, comprise: forcing press, pressure flat, assembling ball-distributer and bearing fixing device, wherein, described assembling ball-distributer is identical with the dimensions of this bearing plug-in type retainer, and the pocket hole of assembling ball-distributer is straight mouthful of pocket hole; On described bearing fixing device, have the bearing fixing groove of a circle, the below of described bearing fixing groove also has a circle and bearing fixing groove concentrically ringed circular dead slot each other; Assembling ball-distributer pocket hole opening is aimed to retainer pocket hole opening and be placed on retainer, on ball-distributer, press and put pressure flat, forcing press is exerted pressure to flat board downwards, makes plug-in type retainer exit bearing, falls in this circle dead slot.While adopting this device to tear cover open to bearing finished products, retainer is stressed evenly, ensures to tear open the reset condition of the rear each part of cover.But this bearing extractor is for specific bearing (thin-walled deep groove ball bearing) is disintegrated; make retainer indeformable before and after dismounting; realize to greatest extent the protection to retainer, be beneficial to this parameter of bearing frictional torque to analyze.
