Description
Technical field
The utility model belongs in machinery overhaul field, is to be a kind ofly fixed on for outer ring the shaft bearing replacer that the bearing on mechanical part is dismantled.
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.
Summary of the invention
In the same parts of some plant equipment, be provided with duplex bearing, 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.The utility model is in above situation and do not damage under the prerequisite of bearing and equipment, and bearing is disassembled from parts, in the situation that changing less parts, the bearing that Commonly Used Size outer ring is fixing is dismantled.
This utility model has made up existing shaft bearing replacer, and the shortcoming that cannot use under special operation condition is suitable for the applicable operating mode of existing shaft bearing replacer simultaneously too; Tapered sleeve can slide arbitrarily on taper pin, and the applicable multiple internal diameter of each tapered sleeve, by changing two, three groups of taper pins and tapered sleeve, can be dismantled conventional bearing, safe and reliable, does not damage dismounting parts, and simple to operate, flexible, a people can operate.
The utility model comprises support (1), portable stanchion (2,6), adjusting nut (3,7), drawing bar (4), drawing nut (5), crossover sub (8), elastic conical drogue (9) and taper pin (10); Portable stanchion (2,6) can be by mobile in the adjustment tank that is adjusted in support (1) of adjusting nut (3,7), to find the most suitable strong point; Drawing bar (4) lower end is provided with crossover sub (8), can supply the different big or small bearing of dismounting time, changes taper pin (10), and taper pin (10) is connected with crossover sub (8) by screw thread; Elastic conical drogue (9) is divided into three lobes, by being installed on the turn in spring groove, three lobes of elastic conical drogue (9) to be held tightly, when elastic conical drogue (9) is slided to taper pin (10), inner surface and taper pin (10) are fitted completely, and when external diameter becomes large gradually, and unlikely coming off; After bearing removal completes, can rap taper pin (10) bottom, 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.
The utility model is narrow and small for unilateral spatial, from the instrument of a side dismounting inner sleeve bearing; Employing taper pin (10) coordinates with elastic conical drogue (9), can be at stripping attachment homonymy swelling bearing inner race.Between taper pin (10) and drawing bar (4), be connected by crossover sub (8), be convenient to change different model taper pin.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 and Fig. 2 are structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 2, this shaft bearing replacer is by part 1 support, part 2,6 portable stanchions, part 3,7 adjusting nuts, part 4 drawing bars, part 5 drawing nuts, part 8 crossover subs, part 9 elastic conical drogues and part 10 taper pins compositions; Part 2,6 can be by moving in the adjustment tank that is adjusted in part 1 of part 3,7 adjusting nuts, to find the most suitable strong point; Part 4 drawing bar lower ends are provided with part 8 crossover subs, can supply the different big or small bearing of dismounting time, change part 10 taper pins, and part 10 taper pins are connected with part 8 crossover subs by screw thread; Part 9 elastic conical drogues are divided into three lobes, by being installed on the turn in spring groove, three lobes of the elastic conical drogue of part 9 are held tightly, and when part 9 elastic conical drogues are slided to part 10 taper pins, inner surface and part 10 taper pins are fitted completely, and external diameter is while becoming gradually large, and unlikely coming off.After bearing removal completes, can rap part 10 taper pin bottoms, under the elasticity of External Force Acting and turn is assisted, part 9 tapered sleeves are to part 10 taper pin top slide, and bearing is release piece 9 tapered sleeves immediately.(on tapered sleeve and taper pin contact-making surface, needing to carry out pre-lubrication, so that operation).
As Fig. 1, bearing block 12 is embedded with duplex bearing, and bearing 13 need take out from both sides; The direction that the elastic conical drogue of shaft bearing replacer 11 will be taken out from bearing together with taper pin reaches bearing 12 inner rings, adjusts relative position between tapered sleeve and taper pin simultaneously, makes elastic conical drogue distending, slightly outstanding bearing inner race inner side, lower end, and fit completely with bearing inner race; Adjust portable stanchion position, make it in suitable position and bearing height, then fixed adjustment nut; With spanner torsion drawing nut, bearing can be pulled out.
Adopt closely-pitched leading screw, make drawing process more laborsaving, can, according to the different bearing bore diameters that will dismantle, change tapered sleeve, taper pin can be changed; In the time only changing tapered sleeve and can not meet instructions for use, need the crossover sub by being located at drawing bar lower end, (but the while is also subject to the restriction of the turn on tapered sleeve to the taper pin of replacing suitable dimension, because tapered sleeve can slide arbitrarily on taper pin, so the dismounting of the applicable multiple internal diameter bearing of each tapered sleeve).
As the equal narrow space in bearing both sides in dismounting, when support and drawing bar cannot be installed, this shaft bearing replacer is suitable for equally: select suitable taper pin and elastic conical drogue, elastic conical drogue and taper pin are stretched in bearing inner race, utilize the just elastic conical drogue swelling of clamp nut that is installed at taper pin end.The hammer that draws that suitable dimension is installed in taper pin end, can take out bearing by the inertia force that draws hammer.
Through practical application, use span 15 ~ 20mm that external diameter is greater than 50mm tapered sleeve is advisable, and the suitable 5 ~ 10mm of use span that external diameter is less than the tapered sleeve of 50mm is advisable.
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, reach identical technique effect; Use needs as long as meet, all within protection domain of the present utility model.
