Abstract
The invention provides a puller structure of a bearing. The puller structure of the bearing can solve the problems of the prior art and guarantee the service life of the bearing. The puller structure of the bearing comprises a support frame. A puller claw is installed on the support frame, the puller claw hooks the outer end surface of the bearing to be disassembled, and a positioning bolt is installed at the central position of the support frame. The puller structure of the bearing is characterized by further comprising a threaded sleeve. One end of the threaded sleeve is rotatably connected with the top tip of the positioning bolt, and the other end of the threaded sleeve is jacked up the shaft end surface of the bearing to be disassembled in a pressing mode.
Description
?
Technical field
The present invention relates to the technical field that bearing and axle are disassembled, be specially a kind of 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 pull horse, and in this process the top axle that will be damaged to, therefore affected service life of axle.
Summary of the invention
For above-mentioned situation, the invention provides a kind of bearing puller structure, can solve the problem that present technology exists, guarantee 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 horse claw hook firmly outer face of bearing to be disassembled 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 of described swivel nut pushes up the axial end that is pressed on bearing described to be disassembled.
After the present invention adopted said structure, owing to having adopted swivel nut, swivel nut was rotatably connected in the top of bolt, the other end of swivel nut pushes up the axial end that is pressed at bearing to be disassembled, like this, just avoid being damaged to axle in implementing drawing process, 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 invention.
The specific embodiment
See Fig. 2, the present invention includes bracing frame 1, draw 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 of swivel nut 7 pushes up the axial end of the axle 4 that is pressed in 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, when making bearing separate 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.
Claims (1)
