Abstract
The utility model provides a hydraulic bearing dismounting tool which is simple in structure and convenient to use, and a locating sleeve and a bearing do not need to be damaged. The hydraulic bearing dismounting tool comprises a pressing plate and is characterized in that a hydraulic cylinder is arranged in the middle of the pressing plate, a piston is arranged in the hydraulic cylinder, a support is arranged on the pressing plate and located on the outer side of the hydraulic cylinder, and an annular plate is arranged on the end portion of the support.
Description
Technical field
The utility model relates to a kind of bearing hydraulic withdrawal tool.
Background technology
Bearing is installed on the axle sleeve that usually adopts interference fit on axle.
In traditional assembly technology, between bearing and axle, need to position with the bearing positioning sleeve of interference fit.Reach use a period of time after installation after, as dismantled bearing and positioning sleeve, will be a job of wasting time and energy, and need a large amount of manpowers to be dismantled, very inconvenient.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of simple in structure, easy to use, without the hydraulic withdrawal tool that destroys positioning sleeve and bearing.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, and the utility model comprises pressure strip, it is characterized in that: the pressure strip middle part is provided with hydraulic cylinder, in hydraulic cylinder, is piston; The arranged outside that is positioned at hydraulic cylinder on described pressure strip has support, and the end of support is provided with annular slab.
As a kind of preferred version of the present utility model, described annular slab is set to semi-circular.
As another kind of preferred version of the present utility model, be provided with the reinforcement screw rod between described clamping sleeve and annular slab.
As the third preferred version of the present utility model, the outer end of described piston is provided with connected unit, is provided with connecting hole on connected unit.
The beneficial effects of the utility model: 1, the utility model is by the Hydraulic Cylinder piston movement, the reaction force acts that piston produces by impeller-hub is to pressure strip, and pressure strip passes to annular slab to power by support again, and annular slab can be pulled out the positioning sleeve on axle, time saving and energy saving, easy to use.
2, the utility model annular slab is set to semi-circular, applicable to irregular bent axle; In addition, it is also easy to install, and without annular slab is unloaded, can directly the utility model be placed in to the end of axle.
3, the utility model arranges the reinforcement screw rod, can increase the utility model bulk strength, avoids pressure strip or annular slab bad by the hydraulic cylinder support.
4, the utility model is provided with connected unit at pistons end, is provided with connecting hole on connected unit; During use, can piston and axle be fixed as one by bolt, stable connection, safe and reliable.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is side view of the present utility model.
In accompanying drawing, 1 is that axle, 2 is that positioning sleeve, 3 is that pressure strip, 4 is that hydraulic cylinder, 5 is that piston, 6 is that connected unit, 7 is that reinforcement screw rod, 8 is that annular slab, 9 is that support, 10 is suspension ring.
The specific embodiment
The utility model comprises pressure strip 3, it is characterized in that: pressure strip 3 middle parts are provided with hydraulic cylinder 4, in hydraulic cylinder 4, are piston 5; The arranged outside that is positioned at hydraulic cylinder 4 on described pressure strip 3 has support 9, and the end of support 9 is provided with annular slab 8.
As a kind of preferred version of the present utility model, described annular slab 8 is set to semi-circular.
As another kind of preferred version of the present utility model, be provided with between described clamping sleeve and annular slab 8 and strengthen screw rod 7.
As the third preferred version of the present utility model, the outer end of described piston 5 is provided with connected unit 6, on connected unit 6, is provided with connecting hole.
Be provided with suspension ring 10 on described support 9, be convenient to lifting of the present utility model and carrying.
Below in conjunction with accompanying drawing, use procedure of the present utility model is described: at first, piston 5 and 4 of hydraulic cylinders are incorporated on the end face of axle 1, then semiorbicular annular slab 8 are placed in to axle 1 end and block positioning sleeve 2; After pressure strip 3 is fixing with hydraulic cylinder 4, installs between annular slab 8 and pressure strip 3 and strengthen screw rod 7; Finally, pressure source is connected on hydraulic cylinder 4, piston 5 outwards pushes up pressure strip 3 under the effect of hydraulic oil, and pressure strip 3 drives annular slabs 8 by support 9 and reinforcement screw rod 7 and outwards moves; Annular slab 8 ejects positioning sleeve 2, completes the dismantlement work of positioning sleeve 2.
Be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model not is limited to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as meet, all within protection domain of the present utility model.
