Abstract
The utility model discloses a device for disassembling a conical bearing seal assembly, comprising an air cylinder, wherein a rise arm seat (6) is arranged at the upper part of the air cylinder (7), a spotting spindle (11) is arranged at the bottom of the air cylinder (7), a steel wire rope (8) is connected on the rise arm seat (6) and the steel wire rope (8) is connected with a drag hook (9). The trying results show that the utility model has convenient operation, short use time and high efficiency, greatly enhances the production efficiency and plays important role of enhancing the quality of railway bearings. Therefore, in mass production or overhaul of conical railway bearings with seal assemblies, the utility model not only can enhance the production efficiency but also can shorten the production cycle of the bearings.
Description
Technical field
The utility model belongs to the bearing seal assembly extracting tool, relates generally to the provision for disengagement of a kind of conical bearing black box.
Background technology
The circular cone railway bearing dismounting black box that black box is arranged there are following three kinds of situations
1. before using to the client, the client will carry out 2% acceptance inspeciton.Need bearing is decomposed, acceptance(check) finishes, and the acceptance sampling product with 2% is returned original production producer and re-assemblied, and in this case, needs bearing is decomposed, must the dismounting black box.
2. in ordinary production, when press-fiting black box, because of pressure worker's technology of pressure mounting level, the operating mode of forcing press etc. cause black box to press-fit not in place or overvoltage, make product defective, must the dismounting black box.
Because of bearing in real-world operation, reach certain useful life, must return Production of bearing producer and carry out large repairs.Like this, also must the dismounting black box.
According to LL oil sealing dismounting requirement, as shown in Figure 1, existing provision for disengagement has the circular cone railway bearing of black box and vertically places vertically, after will extracting bar 2, nut 3 and being installed together successively with sleeve 5, screw screw 4 by hand, to extract bar 2 is fixed together with sleeve 5, insertion LL oil sealing moves back and unloads in the groove, take off sleeve 5, bracing frame 1 is contained in extracts on the bar, after, unload down up to the LL oil sealing is moved back from bearing with spanner rotating nut 3, the upset bearing moves back with same procedure and to unload opposite side LL oil sealing.
Present method for dismounting efficient is low and the time is longer, and in each dismounting, inserting the circular cone railway bearing LL oil sealing that has black box after must will extracting bar and sleeve and being installed together respectively moves back in 3 hole slots that unload groove, taking off sleeve more successively is contained in bracing frame and extracts on the bar, after screwing nut by hand, up to being moved back from bearing, oil sealing unloads down with the spanner rotating nut; These have all directly prolonged the process time of bearing, the consumption of manpower.
Summary of the invention
The purpose of this utility model provides a kind of easy to operate, the conical bearing black box provision for disengagement that can effectively enhance productivity.
The purpose of this utility model can realize by the following technical solutions: it comprises cylinder, has been provided with arm seat on cylinder top, and cylinder bottom is provided with apotting spindle, is connected with steel wire rope on an arm seat, is connected with drag hook on the steel wire rope.
The outer setting of described cylinder has protective cover.
Described cylinder block is provided with control button.
The utility model is mainly according to the action principle of cylinder, apply it to the moving back in the work of unloading of bearing enclosure assembly, unload in the groove by manual steel drag hook insertion LL oil sealing is moved back, the startup cylinder has driven arm seat and has moved, finish the work of unloading of moving back of LL oil sealing. the utility model has strengthened moving back stability when unloading because apotting spindle is housed in the cylinder bottom. install protective cover additional in the cylinder outside, make cylinder and external isolation, keep cylinder to clean, prolonging the service life of cylinder. the utility model is through on probation, easy to operate, the used time is short, and the efficient height has improved production efficiency greatly, the railway bearing quality is promoted the important effect of having played. like this, when the production in enormous quantities overhaul has the circular cone railway bearing of black box, can enhance productivity later on, can shorten the production cycle of bearing again.
Description of drawings
Accompanying drawing 1 is existing bearing LL oil sealing provision for disengagement structural representation.
Accompanying drawing 2 is structural representations of the present utility model.
Among the figure: 1, bracing frame, 2, extract bar, 3, nut, 4, screw, 5, sleeve, 6, play arm seat, 7, cylinder, 8, steel wire rope, 9, drag hook, 10, protective cover, 11, apotting spindle, 12, air inlet, 13, control button.
The specific embodiment
In conjunction with the accompanying drawings, specific embodiment of the utility model is described.
As shown in Figure 2: the utility model comprises cylinder 7, and the piston rod on cylinder 7 tops has been provided with arm seat 6, and cylinder bottom is provided with apotting spindle 11, is connected with steel wire rope 8 on an arm seat, is connected with drag hook 9 on the steel wire rope 8.Outer setting at cylinder has protective cover 10.Cylinder block be provided with control button 13.Cylinder 7 is provided with the air inlet 12 that is connected with outside tracheae.
At first, withdrawal device is placed on the bearing during use, apotting spindle 11 is installed on the bearing, insert moving back of LL oil sealing and unload in the groove the steel drag hook is manual then, at this moment, start-up control button 13 by cylinder action, is finished the LL oil sealing and is moved back and unload action.
Claims (3)
1. conical bearing black box provision for disengagement, comprise cylinder, it is characterized in that: be provided with arm seat (6) on cylinder (7) top, cylinder (7) bottom is provided with apotting spindle (11), on an arm seat (6), be connected with steel wire rope (8), be connected with drag hook (9) on the steel wire rope (8).
