Abstract
A kind of draw bench special component, including fixed cover, claw, screw rod, claw uses symmetrical split type structure, claw is put together by upper clipping claw and lower claw two parts, a stepped hole is axially formed between upper clipping claw and lower claw after split, small stair hole is adapted with screw rod, and big stepped hole is adapted with bearing inner race external diameter to be removed；Described fixed cover is the hollow cylinder of one, and fixed cover is enclosed on outside claw.Described upper clipping claw and lower claw pawl heart alignment axial centre, described fixed cover are enclosed on the pawl end of upper clipping claw and lower claw.The utility model small volume, accurate positioning is simple in construction, is adapted to use at narrow and small position, and effectively raises the service life of instrument, greatly reduces the time of the maintenance of electric hydraulic pump, reduces the cost for reducing maintenance, improve operating efficiency.
Description
Technical field
Originally it is new to be related to a kind of puller component, more particularly to one kind is exclusively used in the bearing inner race of A320 electric hydraulic pumps 887477
The puller component of dismounting.
Background technology
Horse is drawn to be widely used in the various shaft couplings of dismounting, gear, bearing, the isometric upper fastenings of belt pulley, bearing is machinery
In fixed member.
Rolling bearing is typically made up of inner ring, outer ring, rolling element and retainer, and the effect of wherein inner ring is matched with axle
Close, and rotate together with the axis, outer ring effect is engaged with bearing block, is played a supportive role, in use, the major function of bearing is
Rotary shaft or other movable bodies are supported, rotation or moving movement is guided and bears the load being transmitted to by axle or parts on shaft
Lotus.Therefore, bearing is typically subjected to larger pressure, and when pressure is excessive, easily generation is broken or de- for outer ring and rolling element
Fall, and inner ring is still sleeved on axle, electric hydraulic pump 887477 is when repairing, it is necessary to dismantle in the bearing being tightly attached on axle
Circle, but the position is relatively narrow and small, common to draw horse to have no way of doing it, dismounting of bearing inner race relied on and uses manufacturer at this in the past
The specific purpose tool of ETON companies, and tool life do not grow, wasted time and energy in unloading process, delay production, and easily
Axle is caused to damage, produces economic loss.
The content of the invention
To solve above-mentioned technological deficiency, the utility model provides a kind of drawing horse group for being exclusively used in dismantling bearing inner race
Part, the contact area of draw bench special and bearing inner ring is effectively increased, saves maintenance time, while save maintenance
Cost.
Technical scheme is used by the utility model solves its technical problem：A kind of draw bench special component, its feature exist
In：Including fixed cover, claw, screw rod, claw uses symmetrical split type structure, and claw is by upper clipping claw and lower claw two parts split
Form, a stepped hole is axially formed between the upper clipping claw and lower claw after split, small stair hole is adapted with screw rod, big platform
Rank hole is adapted with bearing inner race external diameter to be removed；Described fixed cover is the hollow cylinder of one, and fixed cover is enclosed on claw
Outside.
Described upper clipping claw and lower claw pawl heart alignment axial centre.
Described to be fixed with internal thread, there is the external screw thread being adapted to fixed cover internal thread at the pawl end of upper clipping claw and lower claw,
Fixed cover is threaded in the pawl end of upper clipping claw and lower claw.
Cross section after described upper clipping claw and the lower claw split is the loop configuration of closure.
The beneficial effects of the utility model are：
（1）Increase contact area, effectively can disassemble the inner ring of bearing;
（2）Tool life is improved, reduces maintenance cost;
（3）The time of maintenance is reduced, improves production efficiency；
（4）The workload of maintenance mans is reduced, makes maintenance enhanced convenience；
（5）The utility model part small volume, accurate positioning is simple in construction, is adapted to use at narrow and small position.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model draw bench special component.
In figure：1st, fixed cover；2nd, upper clipping claw；3rd, lower claw；4th, screw rod；5th, small stair hole；6th, big stepped hole.
Embodiment
The technical scheme in the embodiment of the utility model is clearly and completely described presently in connection with accompanying drawing, this figure is
Simplified schematic diagram, only illustrate basic structure of the present utility model in a schematic way.
Shown in Fig. 1, a kind of draw bench special component of the present utility model, including fixed cover 1, claw and screw rod 4, claw is by upper
Claw 2 and the two parts of lower claw 3 are put together, and a step is axially formed between the upper clipping claw 2 and lower claw 3 after split
Hole, small stair hole 5 are adapted with screw rod 4, and big stepped hole 6 is adapted with bearing inner race external diameter to be removed；The described He of upper clipping claw 2
Lower claw 3 can first be machined and be integrally formed, and split and form along central axis.Described upper clipping claw 2 and the alignment of the pawl heart of lower claw 3
Axial centre, described fixed cover 1 are enclosed on the pawl end of upper clipping claw 2 and lower claw 3, shape between described upper clipping claw 2 and lower claw 3
Into a stepped hole, aperture is adapted with screw rod 4, and macropore is adapted with bearing inner race.
Claw is stuck on bearing inner race in use, upper clipping claw 2 and lower claw 3 first are respectively penetrated into housing, then with fix
The outstanding female connector of set 1 lives claw 2 and lower claw 3, fixedly positioning it, then screw rod 4 will be screwed into the axle center screw thread of combination rear claw
It is interior, finally pull out bearing inner race.
