Description
Technical field
The utility model belongs to disassembling fixture technical field, more particularly to a kind of bearing dismounting tool.
Background technology
At present, electronic drawing horse is applied to rail truck maintenance, mechanical erection, mine maintenance, the support of architectural engineering and one
As weight raising decline and be used outer, still dismantle the round shape workpiece such as belt pulley in various plant equipment, gear, bearing, it is existing
Technology is present because triangle draws the centering of horse to require higher, when dismantling bearing, easily causes bias, bearing is stuck in set
Problem.
The content of the invention
The utility model provides a kind of bearing dismounting tool, exists to solve to propose prior art in above-mentioned background technology
Because triangle draws the centering of horse to require higher, when dismantling bearing, bias is easily caused, the problem of making bearing be stuck in set.
The technical problem that the utility model solves is realized using following technical scheme：A kind of bearing dismounting tool, bag
The snap ring for being connected in cylindrical bearing outer ring is included, the snap ring is connected axially to arm-tie, and the arm-tie is connected to pull bar one end, described
The other end of pull bar is connected to hydraulic pump head one end through special bolt axially across hydraulic pump head, and the hydraulic pump head other end connects
Support one end is connected to, the support other end is fixed on bearing block end face.
Further, the cylindrical bearing is embedded in bearing block end face.
Further, the cooperation of step of the snap ring through its external peripheral surface and cylindrical bearing outer ring bottom face is connected in circle
Axis of a cylinder bearing outer-ring.
Advantageous effects：
1st, this patent is connected axially to arm-tie using the snap ring, and the arm-tie is connected to pull bar one end, the pull bar
The other end is connected to hydraulic pump head one end through special bolt axially across hydraulic pump head, and the hydraulic pump head other end is connected to branch
Frame one end, the support other end are fixed on bearing block end face, because cylindrical bearing outer ring disassembling fixture is mainly by snap ring, drawing
Plate, pull bar, support and the part of special bolt 5 composition, process the screwed hole of installation pull bar, in both sides respectively symmetrically at arm-tie center
Two U-shaped through holes are processed, to ensure that both ends snap ring can move radially adjustment position, carriage center machined through hole, to ensure
Pull bar can pass through on support and be uniformly distributed 4 legs, and support foot hight is more than bearing width and arm-tie thickness sum, snap ring, drawing
Plate, pull bar, support and special bolt are process with high strength steel, snap ring be to after full symmetric overall processing in
Wire cutting forms, it is ensured that two snap ring neck circular arc degrees and machining accuracy is consistent.
2nd, this patent is using step of the snap ring through its external peripheral surface and the cooperation card of cylindrical bearing outer ring bottom face
Cylindrical bearing outer ring is connected to, due to passing through reverse fastening structure so that the snapping of snap ring and bearing is more firm, therefore, is more convenient for
By extraction of the bearing out of bearing block.
3rd, this patent uses hydraulic pump head, and because the hydraulic pressure strength of hydraulic pump head is high, pulling force is big, improves the driving of pulling force
Power.
4th, this patent is simple, practical, suitable for dismounting various bearings.
Brief description of the drawings
Fig. 1 is a kind of structural representation of bearing dismounting tool of the utility model.
Embodiment
The utility model is described further below in conjunction with accompanying drawing：
In figure：
1- cylindrical bearings, 2- snap rings, 3- arm-ties, 4- pull bars, 5- special bolts, 6- hydraulic pump heads, 7- supports, 8- bearings
Seat, 9- steps.
Embodiment：
The present embodiment：As shown in figure 1, a kind of bearing dismounting tool, including it is connected in the snap ring 2 of the outer ring of cylindrical bearing 1, institute
State snap ring 2 and be connected axially to arm-tie 3, the arm-tie 3 is connected to the one end of pull bar 4, and the other end of the pull bar 4 is through special bolt 5
The one end of hydraulic pump head 6 is connected to axially across hydraulic pump head 6, the other end of hydraulic pump head 6 is connected to the one end of support 7, described
The other end of support 7 is fixed on the end face of bearing block 8.
The cylindrical bearing 1 is embedded in the end face of bearing block 8.
The cooperation of step 9 of the snap ring 2 through its external peripheral surface and the outer ring bottom face of cylindrical bearing 1 is connected in cylinder axis
Hold 1 outer ring.
Operation principle：
This patent is connected axially to arm-tie by the snap ring, and the arm-tie is connected to pull bar one end, the pull bar it is another
One end is connected to hydraulic pump head one end through special bolt axially across hydraulic pump head, and the hydraulic pump head other end is connected to support
One end, the support other end are fixed on bearing block end face, due to cylindrical bearing outer ring disassembling fixture mainly by snap ring, arm-tie,
Pull bar, support and the part of special bolt 5 composition, process the screwed hole of installation pull bar at arm-tie center, respectively symmetrically add in both sides
Two U-shaped through holes of work, to ensure that both ends snap ring can move radially adjustment position, carriage center machined through hole, to ensure to draw
Bar can pass through on support and be uniformly distributed 4 legs, and support foot hight is more than bearing width and arm-tie thickness sum, snap ring, arm-tie,
Pull bar, support and special bolt are process with high strength steel, snap ring be to after full symmetric overall processing along center line
Cutting forms, and the utility model solves prior art and existed because triangle draws the centering requirement of horse higher, when dismantling bearing,
Easily cause bias, the problem of making bearing be stuck in set, have alignment degree is good, snapping more firmly, the driving force of pulling force it is big, applicable
In the advantageous effects for dismounting various bearings.
Using the technical solution of the utility model, or those skilled in the art is in the inspiration of technical solutions of the utility model
Under, similar technical scheme is designed, and reach above-mentioned technique effect, it is to fall into the scope of protection of the utility model.
