The lower beam center and the upper beam center which are connected with each other through the double-screw bolt is moved mutually upward and downward along the double-screw bolt, and two ends of the double-screw bolt are locked by the screw nuts. The shaft bearing replacer of the utility model has the advantages of simple structure and easy operation. An inner ring and an outer ring of the shaft bearing are conveniently pulled out, the inner pulling hook and the outer pulling hook are movably connected with the upper beam and the lower beam with an adjustable position, thereby the utility model is applicable in multiple sizes of the shaft bearing, and the application scope is wide.

Description

Omnipotent shaft bearing replacer

Technical field

The utility model relates to the provision for disengagement of dismantling bearing, especially can pull out the omnipotent shaft bearing replacer of bearing inner race and outer ring.

Background technology

Bearing is mechanical field a kind of parts commonly used, is mainly used in the support at power transmission shaft two ends, makes power transmission shaft transferring power under bearings of rotation.In long-term, at a high speed use, if damage of bearings or destroyed just need be taken bearing apart, mainly be that bearing inner race and outer ring are disassembled, be convenient to maintenance, replacing etc.Because the special construction of bearing disassembles usually effort, time-consuming, very inconvenient with bearing inner race and outer ring.In the prior art, known shaft bearing replacer structure is the three-jaw hook, and it is by propping up the utensil end face, utilizes three claw hooks to live bearing inner race and will rise and extract.This utensil structure is complicated and only can pull out bearing inner race, and bearing outer ring is not had corresponding dismounting apparatus.

Summary of the invention

Can not dismantle the deficiency of bearing outer ring in order to overcome three-jaw hook of the prior art, the utility model provides a kind of shaft bearing replacer, and this stripping attachment can not only be dismantled bearing inner race, can also dismantle bearing outer ring, and structure is simple relatively.

The technical scheme that its technical problem that solves the utility model adopts is:

Omnipotent shaft bearing replacer, it is characterized in that: comprise nut, studs, entablature, sill, outward pull out hook, in pull out hook, pull out outward hook and in pull out hook and respectively have two, the upper end of pulling out hook outward flexibly connects by connector and entablature, in pull out the upper end of hook by connector and sill flexible connection; The lower end of pulling out hook outside is provided with outer gib head, is provided with interior gib head in interior lower end of pulling out hook; Sill is connected by studs with the entablature center, can move up and down along studs mutually, and the studs two ends are pinned by nut;

Further be characterised in that: two are pulled out distance between the hook outward greater than interior distance of pulling out between the hook, and the direction of outer gib head is inside, and the direction of interior gib head is outside.

Shaft bearing replacer of the present utility model with respect to prior art, has following characteristics:

1, simple in structure, easy operating; Can extract the inner ring and the outer ring of bearing more easily.

2, pull out hook in, pull out hook outward and all be movably connected on entablature and the sill, the position is adjustable, can adapt to the bearing of plurality of specifications, and the scope of application is extensive.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the structural representation of this shaft bearing replacer.

Among the figure: 1-nut, 2-studs, 3-entablature, 4-connector, 5-sill, 6-pull out outward hook, 7-in pull out hook, 8-outer gib head, 9-interior gib head, 10-chute.

The specific embodiment

As shown in drawings, this shaft bearing replacer comprises nut 1, studs 2, entablature 3, connector 4, sill 5, pull out hook 6 outward, in pull out hook 7, outer gib head 8 and interior gib head 9, pull out outward hook 6 and in pull out hook 7 and respectively have two, the upper end of pulling out hook 6 outward flexibly connects by connector 4 and entablature 3, in pull out hook 7 the upper end flexibly connect by connector 4 and sill 5, pull out outward hook 6 and in pull out hook 7 can be by the size of bearing and disassembly direction around connector 4 axial rotation, two are pulled out distance between the hook 6 outward greater than interior distance of pulling out between the hook 7, pull out the outer ring that hook 6 is used to pull out bearing outward, in pull out the inner ring that hook 7 is used to pull out bearing.The lower end of pulling out hook 6 outside is provided with outer gib head 8, gib head 9 in interior lower end of pulling out hook 7 is provided with, and in this shaft bearing replacer when work,, outer gib head 8 and interior gib head 9 contact with the outer ring of bearing or inner ring respectively and hook, and firmly it are pulled up.The direction of outer gib head 8 is inside, and the direction of interior gib head 9 is outside, can hook the outer ring or the inner ring of bearing respectively.Sill 5 is connected by studs 2 with entablature 3 centers, can move up and down along studs 2 mutually, and studs 2 two ends are pinned by nut 1.

Connector 4 can be the parts that are rotatably connected such as axle, pin, with connector 4 will pull out outward hook 6 and in pull out hook 7 and be connected on entablature 3 or the sill 5, make outer pull out hook 6 and in pull out hook 7 can be by the size of bearing and disassembly direction around connector 4 axial rotation.Pull out outward hook 6 with in pull out the connector 4 that hook 7 is connected to entablature 3 or sill 5 can be identical, also difference can be arranged.

Simultaneously,, on entablature 3 and/or sill 5, chute 10 is set as further improvement of the utility model, pull out outward hook 6 and in pull out hook 7 and be connected on the chute 10 through connector 4; Chute 10 has certain length, thus outer pull out hook 6 and in pull out hook 7 and can move along chute 10, more can conveniently adjust two and pull out the distance of pulling out in hook 6 or two between the hook 7 outward, to adapt to the bearing of different-diameter, enlarge its scope of application.Entablature 3 can be identical with chute 10 on the sill 5, also difference can be arranged.

The course of work of the utility model stripping attachment: during use,, adjust two and pull out the distance of pulling out in hook 6 or two between the hook 7 outward at first according to the diameter of bearing; When needs pull out the outer ring, utilize the outer outer ring that the outer gib head 8 on the hook 6 hooks bearing of pulling out, pull out hook 7 as supporting in utilizing simultaneously, it is against axial end, with the hands hold entablature 3 and sill 5, extract the outer ring by lever principle; When needs pulled out inner ring, the interior gib head 9 that pulls out in the utilization on the hook 7 hooked bearing inner race, utilized its outer hook 6 that pulls out to be supported on the outer wall of bearing simultaneously, with the hands held entablature 3 and sill 5, can extract inner ring by lever principle.
