Description
Technical field
The utility model relates to bearing removal field, is specifically related to a kind of bearing demounting appliance.
Background technology
At present in the middle of plant equipment maintenance, usually adopt for bearing removal and draw horse to carry out drawing operation, but adopt this dismounting mode easily to damage bearing and motor shaft, impact reuses.
Fig. 1 is the utility model patent " bearing disassembling device " of Jiangyin Bo Feng specific type of electric machine Co., Ltd application on December 25th, 2013, the patent No.: ZL201320859229.1, this bearing disassembling device comprises chuck 1, screw rod 2 and gripper shoe 3, chuck 1 has a gap 1.1, and chuck 1 is provided with two chuck screws 1.2, gripper shoe 3 is provided with two gripper shoe screws 3.1, screw rod 2 is provided with two, one end of screw rod 2 is spun in chuck screw 1.2, and the other end is spun in gripper shoe screw 3.1.During use, be placed on motor shaft by chuck 1 by gap 1.1, utilize jack one end to withstand on motor shaft, the other end withstands in gripper shoe 3 and is pulled out by bearing, and bearing adopts face to contact with chuck 1, uniform force, reduces damage during dismounting.
Because chuck 1 entirety is in horse-hof shape, when utilizing jack to be pulled out by bearing, be easy to occur discontinuity, motor shaft axle center is departed from chuck 1 position, finally causes chuck 1 to come off, bearing cannot be departed from from motor shaft.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of bearing demounting appliance, and its structure is simple, easy to operate, stability is high.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of bearing demounting appliance, comprise chuck, screw rod and gripper shoe, described chuck is two, chuck has a gap, and on chuck, is evenly provided with three chuck screws, described gripper shoe is provided with four gripper shoe screws, chuck screw one_to_one corresponding on the chuck that described four gripper shoe screws are oppositely overlapping with two, described screw rod is four, and one end of this screw rod is spun in chuck screw, and the other end is spun in corresponding gripper shoe screw.
Also be respectively equipped with four fixing threaded holes at described two reverse laps of chuck, this fixing threaded hole is provided with the bolt of coupling.
The groove mated with jack top is provided with in the middle of described gripper shoe.
Utility model works principle: during dismounting bearing, two chucks are oppositely placed on motor shaft by gap, now two chucks are oppositely overlapping, bolt is spun in fixing threaded hole, chuck is fixed each other, four screw rod two ends are spun in chuck screw and gripper shoe screw again, finally utilize jack one end to withstand on motor shaft, the other end withstands in gripper shoe groove and is pulled out by bearing.
The beneficial effects of the utility model are:
1) by arranging two chucks, can better be fixed on motor shaft after reverse overlap, preventing from departing from and come off, after adopting four screw rods, reduce the load of screw rod in background technology, make stressed evenly;
2) gripper shoe is provided with groove, can better fix jack position, prevent application point from departing from, affect bearing removal and carry out.
Accompanying drawing explanation
Fig. 1 is background technology middle (center) bearing provision for disengagement structural representation;
Fig. 2 is the utility model structural representation;
Fig. 3 is the utility model chuck structure schematic diagram.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 2,3, a kind of bearing demounting appliance, comprise chuck 1, screw rod 2 and gripper shoe 3, chuck 1 is two, and chuck 1 has a gap 11, and on chuck 1, be evenly provided with three chuck screws 12, gripper shoe 3 is provided with chuck screw 12 one_to_one corresponding on four gripper shoe screws, 31, four gripper shoe screws 31 chuck 1 oppositely overlapping with two, screw rod 2 is four, one end of this screw rod 2 is spun in chuck screw 12, and the other end is spun in corresponding gripper shoe screw 31.
Also be respectively equipped with four fixing threaded holes 13 at the reverse lap of two chucks 1, this fixing threaded hole 13 is provided with the bolt 14 of coupling.
The groove 4 mated with jack top is provided with in the middle of gripper shoe 3.
During dismounting bearing, two chucks 1 are oppositely placed on motor shaft by gap 11, now two chucks 1 are oppositely overlapping, bolt 14 is spun in fixing threaded hole 13, chuck 1 is fixed each other, four screw rod 2 two ends are spun in chuck screw 12 and gripper shoe screw 31 again, finally utilize jack one end to withstand on motor shaft, the other end withstands in gripper shoe 3 groove 4 and is pulled out by bearing.
More than show and describe general principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
