Description
Technical field
The utility model relates to a kind of extracting tool more particularly to a kind of bearing dismounting tools.
Background technique
There are many existing bearing assembling-disassembling tools, but it is difficult to there is disassembly for the bearing of some major diameters, or dismounts
Tool is complicated, seriously affects the efficiency of dismounting bearing.For example the bearing assembling-disassembling tools of SKF are primarily adapted for use in rolling bearing and internal diameter
Less than being just relatively applicable in for 30mm, for the bearing but not good dismounting method of major diameter, the tradition such as hammering method are generallyd use
Mode is removed, and dismantling device on the market is little for specific equipment effectiveness.
Chinese patent notification number is CN205968845U, is disclosed on 2 22nd, 2017 a kind of for main shaft bearing disassembly
Pushing meanss, including main shaft, bearing, the shaft shoulder and top power disk；Bearing is installed, bearing is adjacent with the shaft shoulder, shaft shoulder position on main shaft
The mating surface of installation top power disk, top power disk and bearing inner race end face is equipped with tapped through hole, when dismantling bearing, installs on the power disk of top
Bolt corresponding with tapped through hole, screws in bolt, and bolt can eject bearing demolition.Main shaft bearing is dismantled using fixation
Main shaft support does not influence the operating accuracy of main shaft after guaranteeing disassembly bearing；Above-mentioned patent is directly to withstand bearing using bolt,
Bearing is dismantled using the pressure on top surface of bolt, since bearing acts directly on bearing, the acting surface of bolt and bearing is smaller,
There is the possibility of damage in disassembly process to bearing.
Utility model content
In order to overcome the drawbacks of the prior art, the utility model provides a kind of bearing dismounting tool, and the purpose is to the works
During disassembly bearing, it not will cause the damage of bearing, effectively improve working efficiency.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of bearing dismounting tool, it is characterised in that: including ring flange, opposite opened flange and bolt, the ring flange with
The setting of opposite opened parallel flange, reserves the gap for accommodating bearing, ring flange and opposite opened method between ring flange and opposite opened flange
It is bolted between orchid, rotation bolt adjusts the distance between ring flange and opposite opened flange；The aperture of ring flange is less than
The aperture of bearing；Opposite opened flange aperture is greater than the aperture of bearing, and is less than the inner ring outer diameter of bearing；When dismantling bearing, flange
Disk and opposite opened flange are separately mounted to the two sides of bearing, and fastening bolt removes bearing.
The opposite opened flange is made of two pieces of flange valves, and flange valve described in every piece is that central angle is less than greater than 90 degree
180 degree is recessed into step under one end of flange valve, and the step on two pieces of flange valves is cooperatively connected composition circular flange disk, i.e.,
Step on two pieces of flange valves is mutually chimeric, forms a standard flange.
The flange valve is that the central angle of central angle is 135 degree, and the central angle of step is 45 degree, the flange valve and flange
Disk is equipped with screw hole, and bolt passes through screw hole mounting flange and opposite opened flange.
The utility model has the advantage that
1, the utility model is for the bearing connect on main shaft that rises, when needing to dismantle, by two methods of opposite opened flange
Blue valve is fastened on the main shaft of bearing side (main shaft is fixed on machine pedestal, generally multi-diameter shaft), ring flange peace
Mounted in the other side of bearing, spindle nose (because its aperture is less than the aperture of bearing) can be withstood on, or is mounted on multi-diameter shaft, it is split
Formula flange and ring flange are connected with stay bolt, and the inner hole of opposite opened flange is slightly larger than the internal diameter of bearing, and the inner hole of ring flange is less than
It is used after only needing to be assembled two parts flange before and after flange in disassembly using the tooling of the design in the aperture of bearing
Suitable spanner fastening bolt can will need the bearing removed to remove, and not will cause the damage of bearing, effectively
Improve working efficiency.
2, the utility model open type flange is made of two pieces of flange valves, and flange valve described in every piece is that central angle is greater than 90 degree
Less than 180 degree, step is recessed under one end of flange valve, the step on two pieces of flange valves, which is cooperatively connected, forms circular flange
Disk, i.e. step on two pieces of flange valves is mutually chimeric, forms a standard flange.For firm on lathe or workbench main shaft
Bearing and dismantled using fastening bolt convenient for flange is arranged in the two sides of bearing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the flange valve in the utility model；
Fig. 3 is the side view of Fig. 2；
Marked in the figure: 1, ring flange, 2, opposite opened flange, 2.1, flange valve, 2.2, step, 3, bolt, 4, bearing, 5, master
Axis.
Specific embodiment
The utility model is further elaborated with reference to the accompanying drawing, but the utility model is not limited to following embodiment,
The method is conventional method unless otherwise instructed, and the material can be gotten from open business unless otherwise instructed.
As shown in Figure 1, Figure 2 and Figure 3, a kind of bearing dismounting tool, including ring flange 1, opposite opened flange 2 and bolt 3, institute
It states ring flange 1 to be arranged in parallel with opposite opened flange 2, the logical center line of the two is on same line, ring flange 1 and opposite opened flange 3
Between preset clearance, when dismantling bearing 3, bearing 3 is between ring flange 1 and opposite opened flange 2, i.e. 3, bearing in the gap
In in the gap.It is connected between ring flange 1 and opposite opened flange 2 by bolt 3, rotation bolt 3 adjusts ring flange 1 and opposite opened
The distance between flange 2；The aperture of ring flange 1 is less than the aperture of bearing 4；2 aperture of opposite opened flange is greater than the aperture of bearing 4,
And it is less than the outer diameter of bearing 4；When dismantling bearing, ring flange is separately mounted to the two sides of bearing, fastening bolt with opposite opened flange
Remove bearing.
Opposite opened flange 2 is made of two pieces of flange valves 2.1, and flange valve described in every piece is 2.1 central angles greater than 90 degree small
In 180 degree, i.e., it is a large semicircle that flange valve, which is 2.1, and step 2.2(such as Fig. 2, Fig. 3 institute is recessed under one end of flange valve 2.1
Show), the step 2.2 on two pieces of flange valves 2.1 is cooperatively connected composition circular flange disk, i.e. step phase on two pieces of flange valves
It is mutually chimeric, form a standard flange.
Further, it is 135 degree that flange valve, which is the central angle of central angle, and the central angle of step is 45 degree, the flange valve
It is equipped with screw hole with ring flange, bolt passes through screw hole mounting flange and opposite opened flange.
Utilize the detailed process of tooling disassembly bearing are as follows: (main shaft 5 is general as shown in Figure 1, bearing 4 rises and connects on main shaft 5
It is to fix mechanically, or do not need to remove on main shaft 5), by 2.1 sets of two pieces of flange valves of opposite opened flange 2 on main shaft 5,
And be located on the main shaft of mechanical side, i.e., opposite opened flange 2 is located between 4 machinery of bearing, and ring flange 1 withstands on the end of main shaft 5
(or on rank of ladder main shaft) is then generally stay bolt using more bolt 3(, and specific length is according to the size and axis of bearing
Length determine) ring flange 1 is connect with opposite opened flange 2, can will need to remove with suitable spanner fastening bolt
Bearing remove, and not will cause the damage of bearing.
