Abstract
The utility model provides a locomotive shaft bearing dismounting device, is including moving back board, baffle, screw rod and locate and move back the hydraulic means between board and the baffle and draw the cover, the baffle is connected through the pull rod between the board with moving back, hydraulic means includes cavity plunger pneumatic cylinder, motor -driven pump and defeated oil feed pipe, drawing set one end and shaft terminal surface and passing through bolted connection, screw rod one end set is connected with drawing, and the other end passes the baffle stretches out, cavity plunger hydraulic pressure cylinder liner is outside the screw rod. Because it does not have violent impact between board and the bearing terminal surface to move back, and only mutual extrusion force, consequently can not harm the bearing, after the bearing withdrawed from the shaft totally, the bearing housing was put in drawing, take off draw the cover can be with bearing and shaft clean separation.
Description
Technical field
The utility model bearing disassembling device, especially a kind of locomotive axle bearing disassembling device.
Background technology
The existing mode for dismantling bearing is varied, such as common are the mode of beaing, although this kind of mode is simple, quick, larger to the infringement of bearing.For the bearing of locomotive axle, because its performance directly affects the running of locomotive wheel, the safe operation of relation locomotive, so mode of beaing common is at present worthless for demountor axletree bearing, needs special instrument to dismantle bearing.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of locomotive axle bearing disassembling device, can safe being disassembled from wheel shaft by bearing and do not damage bearing.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of locomotive axle bearing disassembling device, comprise and move back plate, baffle plate, screw rod and be located at the hydraulic means that moves back between plate and baffle plate and draw cover, described baffle plate is connected by pull bar with moving back between plate, described hydraulic means comprises hollow plunger hydraulic cylinder, electrodynamic pump and conveying oil pipe, described draw cover one end and wheel axle end surface be bolted, screw rod one end is connected with drawing to overlap, the other end stretches out through described baffle plate, and described hollow plunger hydraulic cylinder is outside screw rod.The utility model principle: when bearing disassembles from wheel shaft by needs, will move back the inner face of board at bearing; By the end part aligning of the one end and wheel shaft of drawing cover, and cover will be drawn by bolt and link together with wheel axle end surface; Screw rod and hollow plunger hydraulic cylinder are installed, adjust each device location and make hollow plunger hydraulic cylinder, draw cover, wheel shaft on the same line; Start hollow plunger hydraulic cylinder, its piston portion with draw cover and offset, cylinder body and baffle plate offset, cylinder body is constantly to baffle plate applied thrust, baffle plate by pull bar by pull transfer to moving back plate, thus move back plate bearing withdrawn from wheel shaft, there is no fierce impact owing to moving back between plate and bearing face, and be only mutual extruding force, therefore can not damage bearing; After bearing exits wheel shaft completely, bearing holder (housing, cover) is drawing on cover, takes off to draw cover and bearing can be separated completely with wheel shaft.
As improvement, described in move back plate and take the shape of the letter U.
As improvement, described in move back on plate and baffle plate and be equipped with hanger, convenient handling is carried out to provision for disengagement.
As improvement, described in draw cover and be provided with towards one end of hollow plunger hydraulic cylinder and draw sleeve gasket, prevent the piston of hydraulic stem from directly contacting and damage and draw cover with drawing to overlap.
As improvement, described hydraulic means also comprises the dolly for carrying hollow plunger hydraulic cylinder.
The beneficial effect that the utility model is compared with prior art brought is:
There is no fierce impact owing to moving back between plate and bearing face, and be only mutual extruding force, therefore can not damage bearing; After bearing exits wheel shaft completely, bearing holder (housing, cover) is drawing on cover, takes off to draw cover and bearing can be separated completely with wheel shaft.
Accompanying drawing explanation
Fig. 1 is the utility model frock view.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in Figure 1, a kind of locomotive axle bearing disassembling device, comprises moving back plate 3, baffle plate 2, screw rod 10 and being located at the hydraulic means that moves back between plate 3 and baffle plate 2 and drawing cover 7 of U-shaped.Described baffle plate 2 is connected by pull bar 5 with moving back between plate 3, makes the two link.Described hydraulic means comprises hollow plunger hydraulic cylinder 1, electrodynamic pump (sign), conveying oil pipe (sign) and the dolly (sign) for carrying hollow plunger hydraulic cylinder 1, describedly draw cover 7 one end and wheel shaft 8 end face is bolted, the other end is provided with and draws sleeve gasket; Screw rod 10 one end is through drawing sleeve gasket 6 and drawing cover 7 and be connected, and the other end stretches out through described baffle plate 2; Described hollow plunger hydraulic cylinder 1 is enclosed within outside screw rod 10, and is placed in and draws between cover 7 and baffle plate 2.Described moving back on plate 3 and baffle plate 2 is equipped with hanger 9, conveniently carries out handling to provision for disengagement.
The utility model principle: when bearing disassembles from wheel shaft 8 by needs, will move back plate 3 and be stuck in the inner face of bearing; By the end part aligning of the one end and wheel shaft 8 of drawing cover 7, and cover 7 will be drawn by bolt and link together with wheel shaft 8 end face; Screw rod 10 and hollow plunger hydraulic cylinder 1 are installed, adjust that each device location makes hollow plunger hydraulic cylinder 1, draws cover 7, wheel shaft 8 on the same line; Start hollow plunger hydraulic cylinder 1, its piston portion with draw cover 7 and offset, cylinder body and baffle plate 2 offset, cylinder body is constantly to baffle plate 2 applied thrust, baffle plate 2 by pull bar 5 by pull transfer to moving back plate 3, thus move back plate 3 bearing withdrawn from wheel shaft 8, there is no fierce impact owing to moving back between plate 3 and bearing face, and be only mutual extruding force, therefore can not damage bearing; After bearing exits wheel shaft 8 completely, bearing holder (housing, cover) is drawing on cover 7, takes off to draw cover 7 and bearing can be separated completely with wheel shaft 8.
