Abstract
The utility model provides a bearing puller structure. By the bearing puller structure, problems in the prior art can be solved, and service life of a bearing can be ensured. The bearing puller structure comprises a supporting frame, wherein puller claws are arranged on the frame and hook an outer end surface of the bearing to be dismounted; and a positioning bolt is arranged in the center of the supporting frame. The bearing puller structure is characterized by also comprising a screw sleeve, wherein one end of the screw sleeve is rotatably connected to the top of the positioning bolt; and the other end of the screw sleeve presses against the end surface of the bearing to be dismounted.
Description
Technical field
The utility model relates to the technical field that bearing and axle are disassembled, and is specially the bearing puller structure.
Background technology
When disassembling bearing and axle, need to use a kind of horse of drawing.The bearing draw bench special structure that prior art adopts, as shown in Figure 1, the center of bracing frame 1 is equipped with bolt 3, the excircle of bracing frame 1 is equipped with and draws horse pawl 2, the end face of bolt 3 is close to the axial end of axle 4 to be disassembled, and draws the pawl end 5 of horse pawl 2 to be close to the outer face away from axial end of bearing inner race 6.There is a drawback in this structure, and the top of the end face of bolt must be withstood axle, bracing frame is moved outward draw horse, and in this process the top axle that will be damaged to, so affected service life of axle.
Summary of the invention
For above-mentioned situation, the utility model provides the bearing puller structure, can solve the problem that present technology exists, and guarantees the service life of axle.
Its technical scheme is such, it comprises bracing frame, draw the horse pawl to be installed on support frame as described above, the described firmly outer face of bearing to be disassembled of horse claw hook of drawing, center at support frame as described above is equipped with bolt, it is characterized in that: it also comprises swivel nut, and an end of described swivel nut is rotatably connected in the top of described bolt, and the other end top of described swivel nut is pressed on the axial end of bearing described to be disassembled.
After the utility model adopts said structure, owing to adopted swivel nut, swivel nut to be rotatably connected in the top of bolt, the other end top of swivel nut is pressed on the axial end at bearing to be disassembled, like this, in implementing drawing process, just avoid being damaged to axle, therefore can guarantee the integrality of axle.
Description of drawings
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
See Fig. 2, the utility model comprises bracing frame 1, draws horse pawl 2, draw horse pawl 2 to be installed on the excircle of bracing frame 1, draw the pawl end 5 of horse pawl 2 to be close to the outer face away from axial end of bearing inner race 6, and hook the outer face 6-1 of bearing, the center of bracing frame 1 is equipped with bolt 3, and the top place of bolt 3 is connected with swivel nut 7, and the end face 7-1 top of swivel nut 7 is pressed in the axial end of the axle 4 of bearing to be disassembled.Shaft strength point is at bearing inner race, bearing ball and outer ring all do not stress when extracting bearing like this, so that bearing when separating with axle bearing ball indeformable, can not scratch the steel bead groove surface, and (putting down) end face top last item end face of swivel nut in drawing process, can not be damaged to axle yet, more guaranteed the complete of axle, can continue to use.
