Description
Technical field
The utility model belongs to the machinery overhaul field, relates to a kind of simple and easy bearing driver-extractor that is used to dismantle small size bearing.
Background technology
Existing bearing driver-extractor is generally the tube structure that the cylindric arc pulling claw of two halves constitutes; With cuff the cylindric pulling claw of two halves is waled the closed cylindrical shell of formation during use; One end of two arc pulling claws is connected with nut, and rotation under external force withstands on the hot candied bar that rises on the arbor end face then, makes nut do counter motion; Drive the arc pulling claw and on bearing, produce outside pulling force, at last bearing is pulled down.
The deficiency of existing driver-extractor is, needs during use pulling claw, nut, cuff are assembled, be awkward and parts complicated.
The utility model content
The purpose of the utility model is to the problem that exists in the prior art a kind of simple and easy bearing driver-extractor simple in structure to be provided.
For this reason, the utility model adopts following technical scheme:
A kind of simple and easy bearing driver-extractor has comprised and has pulled out case, plays hot candied bar, and wherein, said is pulled out the case bottom for uncovered, rises to pull out case one end and be provided with the U-shaped opening, and the other end is provided with perforate, and said tapping is provided with and said the nut that hot candied bar is suitable.
Be the friction between minimizing and arbor, said leading screw termination is spherical in shape.
For being convenient for carrying, said top of pulling out case is provided with handle.
The simple and easy bearing driver-extractor that the utility model provides is simple in structure, easy to use, need not suit and is convenient for carrying.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the left view of the utility model;
Fig. 3 is the fundamental diagram of the utility model.
The specific embodiment
Like Fig. 1, Fig. 2, shown in Figure 3, a kind of simple and easy bearing driver-extractor has comprised and has pulled out case 1, plays hot candied bar 2, and wherein, it is uncovered rising and pulling out case 1 bottom, rises to pull out case one end and be provided with U-shaped opening 3, and the other end is provided with perforate 4; Perforate 4 places are provided with nut 6, and it is suitable with nut 6 to play hot candied bar 2.Leading screw 2 ends are spherical in shape.Work the top of pulling out case 1 and be provided with handle 5.
During use, will rise and pull out case 1 opening end down, and make U-shaped opening 3 pass arbor 8; Arbor 8 and bearing 7 covered on pulled out in the case 1, made and pulled out the end end face that case 1 has U-shaped opening 3 and be close to bearing 7 end faces, tightened after will playing hot candied bar 2 aligning arbors 8 centers; Use monkey wrench and afterburning sleeve pipe tightly to move hot candied bar 2 then; Make nut 6 produce counter motions with this, driven and pulled out case 1 and on bearing 7, produce outside active force, gradually bearing 7 is disassembled at last.
