Abstract
The utility model relates to a detacher tool and especially relates to a bearing detacher device. A rack of the bearing detacher device is connected with a drawing rod; a drawing nut is connected to the drawing rod; a first movable stand column (I) and a second movable stand column (II) can move on an adjusting channel of the rack and are respectively fixedly connected with each other via a first adjusting nut (I) and a second adjusting nut (II); the lower end of the drawing rod is provided with a conversion joint; the conversion joint is connected with a taper pin; an elastic taper pin sleeve sleeves the taper pin; the elastic taper pin sleeve is divided into three petals; and the three petals of the elastic taper pin are tightly held by the elastic taper pin via a spring ring, so the internal surface of the elastic taper pin is tightly applied to the taper pin and does not fall off the bottom with a size the same as the diameter of the taper pin. By the use of the bearing detacher device, double bearings can be relatively taken out with a small detaching distance; the bearing detacher device possesses simple and flexible operation, safety and reliability; and a deficiency that a present bearing detacher cannot detach double bearings with a small distance in a relative way is overcome via the bearing detacher device.
Description
Technical field:
The utility model relates to a kind of extracting tool, particularly a kind of bearing removal apparatus.
Background technology:
Dismantle for the bearing that outer ring is fixing, existing extracting tool generally has two kinds, one is " support-board type ", be about to pass from bearing is wanted the opposite side inner ring of removing direction with the stretching bar of supporting plate, supporting plate is stuck in bearing one end, in modes such as threaded screw rod, hydraulic pressure, worm and gears for the other end, bearing is extracted; The second is " three-jaw pull hook formula ", and the direction that will take out from bearing after closing up by elastic three-jaw reaches the bearing other end, and three-jaw pull hook is stuck on bearing inner race, in modes such as threaded screw rod, hydraulic pressure, worm and gears for the other end, bearing is extracted.But be provided with duplex bearing in the same parts of part plant equipment, and two distance between bearings are little, and two bearings will could take out in opposite directions, and existing shaft bearing replacer cannot take out bearing.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of bearing removal apparatus, this device realized can dismantling bay apart from duplex bearing little and that will take out in opposite directions, simple to operate flexibly, safe and reliable.Overcome existing shaft bearing replacer cannot dismantling bay apart from deficiency little and duplex bearing that will take out in opposite directions.
Technical solution adopted in the utility model is: a kind of bearing removal apparatus, comprises support; On support, connect drawing bar, on drawing bar, connect drawing nut, portable stanchion I and portable stanchion II can move and be connected and fixed by adjusting nut I and adjusting nut II respectively on the adjustment passage of support, drawing bar lower end is provided with crossover sub, crossover sub connects taper pin, elastic conical drogue is sleeved on taper pin, elastic conical drogue is divided into three lobes, elastic conical drogue is held three lobes of elastic conical drogue tightly by turn, elastic conical drogue inner surface and taper pin is fitted tightly and can not come off from the large bottom of taper pin diameter.
The beneficial effects of the utility model are: the utility model is owing to having adopted elastic conical drogue and taper pin, thus have can dismantling bay apart from function little and duplex bearing that will take out in opposite directions, simple to operate flexibly, safe and reliable.
Accompanying drawing explanation:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
The specific embodiment:
As shown in Figure 1 and Figure 2, a kind of bearing removal apparatus, comprises support 1, on support 1, connect drawing bar 4, on drawing bar 4, connect drawing nut 5, portable stanchion I 2 and portable stanchion II 6 can move and be connected and fixed by adjusting nut I 3 and adjusting nut II 7 respectively on the adjustment passage of support 1, drawing bar 4 lower ends are provided with crossover sub 8, can supply the different big or small bearing of dismounting time, change taper pin 10, crossover sub 8 connects taper pin 10, elastic conical drogue 9 is sleeved on taper pin 10, elastic conical drogue 9 is divided into three lobes, elastic conical drogue 9 is held three lobes of elastic conical drogue 9 tightly by turn, elastic conical drogue 9 inner surfaces and taper pin 10 are fitted tightly and can not come off from the large bottom of taper pin 10 diameters.When elastic conical drogue 9 slides to taper pin 10, inner surface and taper pin 10 are fitted completely, and taper pin 10 external diameters are while becoming gradually large, come off and elastic conical drogue 9 is unlikely.After bearing removal completes, can rap taper pin 10 bottoms, under the elasticity of External Force Acting and turn is assisted, elastic conical drogue 9 is to taper pin 10 top slide, and bearing departs from elastic conical drogue 9 immediately.
When use, the direction that elastic conical drogue 9 will be taken out from bearing together with taper pin 10 reaches bearing inner race, adjusts relative position between elastic conical drogue 9 and taper pin 10 simultaneously, makes elastic conical drogue 9 distendings, slightly outstanding bearing inner race inner side, lower end, and fit completely with bearing inner race.The position of adjusting portable stanchion I 2 and portable stanchion II 6, makes it in suitable position and bearing height, then fixed adjustment nut I 3 and adjusting nut II 7.With spanner torsion drawing nut 5, bearing can be pulled out.
Be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model is not 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.
