Description
Technical field
The utility model belongs to the taking-up instrument of middle (center) bearing outer ring, a kind of hole.
Background technology
In maintenance of equipment, change bearing and often encounter, complete bearing is easily dismantled usually; The dismounting of the bearing damage especially in hole does not have general instrument, and particularly when bearing damage is serious, only surplus bearing outer ring stays the situation in bearing block, dismantles more difficult; The indigenous method often used is exactly a welding stull in the middle of bearing outer ring, then prizes with crowbar; If a reinforcing bar can be stretched when coming in the other side of bearing block, just withstand stull with reinforcing bar, by hammering reinforcing bar outer end, bearing outer ring is pounded out, does not in addition have instrument to use.Do like this, although can reach the object of removal hole middle (center) bearing outer ring, operation inconvenience, also can damage bearing block.
Summary of the invention
The purpose of this utility model is the taking-up instrument of openly middle (center) bearing outer ring, a kind of hole, to solve the difficult problem dismantled after hole middle (center) bearing damages.
Technical scheme:
The taking-up instrument of middle (center) bearing outer ring, hole, comprises support, pull pin bar and drag hook; Be set with hammer of pulling pin pulling pin on bar, the lower end of bar of pulling pin is spirally connected support, and at the two ends of support with bearing pin one and bearing pin two, with rotating manner, two drag hooks are housed respectively, the middle part of a drag hook wherein has adjustment screw, and be spirally connected an adjusting screw(rod).
H-shaped made by support, and the draw-in groove wall of left end has left pin shaft hole, and the draw-in groove wall of right-hand member has right pin shaft hole, and two pin shaft holes are all perpendicular to draw-in groove inner chamber.Moving pin rod screw in middle part, pulls pin bar screw and draw-in groove on isoplanar.
The lower end of drag hook one and drag hook two is outwards bent with hook card, and the front of their upper ends all has pin shaft hole.With left pin shaft hole or the right pin shaft hole of bearing pin one or bearing pin two and correspondence, drag hook one or drag hook two are rotatably connected in the draw-in groove of support both sides.
The pull pin outer end of bar is manufactured with boss, for stoping hammer of pulling pin to skid off, and the impulsive force that hammer of pulling pin produces being passed on the hook card of drag hook, forming the power of bearing outer ring of choosing.Bar bottom of pulling pin is manufactured with screw thread, is spirally connected with the bar screw of pulling pin on support.
Namely the taking-up instrument of middle (center) bearing outer ring, a hole is made in the manner described above, during use, two drag hooks are extend in axis hole, rotates adjusting screw(rod), make two of lower end hook cards hold out against pocket at bearing outer ring, then hammer of pulling pin is slided fast, resist the boss of bar outer end of pulling pin, utilize the impulsive force that this produces instantaneously, repeated multiple times, loosened by bearing outer ring gradually, it is extracted the most at last.
The utility model structure is simple, and easily manufacture, the operation of extraction hole middle (center) bearing outer ring is safe, manual operation, does not need by other power, remarkably productive, does not injure bearing block.Avoid employing to knock, cause bearing outer ring and break, then the mode that block-by-block prizes bearing outer ring from hole, to the infringement of bearing block.
Accompanying drawing explanation
Fig. 1 is the taking-up tool construction figure of middle (center) bearing outer ring, hole.
Fig. 2 is the support shape figure installing drag hook and bar of pulling pin.
Fig. 3 is drag hook shape figure.
Fig. 4 is occupation mode schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, as embodiment, technical scheme is further illustrated.
With reference to Fig. 1,2,3, support 4 is drag hook one 2a, the connector of drag hook two 2b and bar 6 of pulling pin.
Hammer 5 of pulling pin is slidably socketed is pulling pin on bar 6, and the outer end of bar 6 of pulling pin makes boss 7, and screw thread is made in bar lower end of pulling pin, and is screwed onto to pull pin in bar screw 4.2 in the middle part of support 4, namely completes the installation of pull pin bar and support.
With the pin shaft hole 2.3 that bearing pin one 1a and bearing pin two 1b is corresponding with on two drag hooks, the left pin shaft hole 4.3 on the draw-in groove of support 4 both sides and the position of right pin shaft hole 4.1, install drag hook one 2a and drag hook two 2b respectively.Like this, left and right two drag hook all with the bearing pin of position for rotating shaft, can rotate in draw-in groove.
In order to the bearing outer ring making the hook card 2.1 of two drag hook lower ends adapt to take out different pore size, and can firm be tightened in bearing outer ring, select the middle part of one of them drag hook to open and regulate screw 2.2, in adjusting screw(rod) 3 advances through hole, adjusting screw(rod) 3 can be held out against on another corresponding drag hook.
The hook card 2.1 of the lower end of drag hook one 2a and drag hook two 2b is made into the form be bent into laterally close to right angle, and its size is unsuitable long, but fineness degree is wanted to bear when taking out bearing outer ring, the power produced when hammer 5 of pulling pin clashes into boss 7 and unlikely damage.
With reference to Fig. 4, bearing outer ring 8 is clamped in the bearing bore 11 of axis hole 10 outer end of bearing block 9 with tight fit form, bearing card jail in bearing bore 11 after, cannot lever up with lever, also the limit, lower end of bearing outer ring 8 can't be pushed up from axis hole 10 lower end, so can only be taken out from top with metal bar.Utilize two drag hooks on the taking-up instrument of middle (center) bearing outer ring, hole, extend in the inner chamber of bearing outer ring 8, with adjusting screw(rod) 3, the lower end of two drag hooks is strutted, make two hook cards 2.1 push up tightly jail on the internal chamber wall of bearing outer ring 8 in recess; Slide near support 4 with hand hammer 5 of pulling pin, firmly boss 7 accelerated slip of hammer 5 to bar 6 outer end of pulling pin of pulling pin, produces one moment impact, bearing outer ring 8 repeatedly can be allowed several times loosening with the combination of bearing block 9, can conveniently take out afterwards.In just using, when conditions permit, allow bearing bore 11 downward as far as possible, making to pull pin to hammer into shape produces stronger instant impact.
Middle (center) bearing outer ring, the hole puller made like this, improves operating efficiency when bearing is changed in maintenance of equipment.
