The utility model content
The technical problem that the utility model will solve is the above-mentioned defective that how to overcome existing bearing removal technology, and a kind of bearing extractor is provided--the bearing outer ring puller.
For solving the problems of the technologies described above, this bearing outer ring puller comprises outer ring fixed mechanism and exhaustion mechanism, and wherein the outer ring fixed mechanism comprises expand pin and expansion sleeve; Wherein the expansion sleeve bottom is divided into many lobes, and its outside is provided with and the corresponding convexity of bearing outer ring groove, and can insert in the bearing outer ring; Said bloated pin is arranged in the expansion sleeve, and the pin bottom of expanding is truncated cone, and expose outside the expansion sleeve on the pin top of expanding; Pulling is expanded and is sold, and the pin bottom of expanding is clamp-oned in the expansion sleeve, with the expansion sleeve distending; Convexity on the expansion sleeve is snapped in the groove of bearing outer ring, and exhaustion mechanism can be pulled out together with bearing outer ring the outer ring fixed mechanism from bearing block.During use, earlier the outer ring fixed mechanism is fixed on the bearing outer ring, then, with exhaustion mechanism the outer ring fixed mechanism is pulled out from bearing block together with bearing outer ring and to get final product.So design, the not fragile distortion of bearing outer ring after the dismounting, also can continue assembling and use.
As optimization, said bloated pin top is screw rod, is furnished with clamp nut on this screw rod.So design through clamp nut, just possibly drawn in expansion sleeve with the pin that expands, and then the outer ring fixed mechanism firmly is fixed on the bearing outer ring, removes fixing also very convenient.
As optimization, the bearing block outside is provided with cushion block, and this cushion block has centre bore, and expansion sleeve passes this centre bore, and its exposed parts matches with exhaustion mechanism.So design, not fragile bearing block.
As optimization, said exhaustion mechanism comprises the hydraulically extensible cylinder, and the cylinder body of this hydraulically extensible cylinder is fixed, and its expansion link front end links to each other with expansion sleeve top.So design, hydraulic operation, convenient.
As optimization, said exhaustion mechanism comprises screw, and said expansion sleeve top excircle is provided with the external screw thread that matches with this screw, and the screw screw thread is opposite with the clamp nut screw thread.So design, simple in structure, exhaustion mechanism strength is big.
As optimization, said exhaustion mechanism comprises lever, and this lever one end acts directly on the bearing block as fulcrum; Expansion sleeve top links to each other with the lever stage casing as stress point; The lever other end is the point of application.So design is easy to operate, rapid.
As optimization, said exhaustion mechanism comprises lever, and this lever one end acts on the cushion block as fulcrum; Expansion sleeve top links to each other with the lever stage casing as stress point; The lever other end is the point of application.So design is difficult for damaging by pressure bearing block.
This bearing outer ring puller has advantage simple in structure, easy to use, during this bearing outer ring puller dismounting bearing outer ring, can not damage bearing outer ring and bearing block, also can continue to assemble usefulness, and assembling is used when extensively being suitable for machine tooling.
