With a brand-new structure designed, the bearing extractor can be used to carry out quick disassembly on a bearing installed on a large-sized motor, and is suitable for bears with different standards.
Description
Technical field
The present invention relates to power engineering technical equipment field, specifically, be related to a kind of bearing extractor and
Method.
Background technology
Electronic machine overhauling is one of working contents of electrical overhaul work, especially Large Copacity high-tension motor, by
Difficult point in work difficulty is big, in technical requirements high always electrical overhaul work and emphasis, why high-voltage motor maintenance is examined
Repair difficulty greatly in addition to technological layer also have one important the reason be just a lack of suitable, practical reliable specific purpose tool.
On the output shaft of motor, it is usually mounted with bearing, when bearing damage, need to its dismounting and change.Existing skill
In art, usually rely on and draw horse or dependence manually to strike and pound bearing removal.But during dismounting, force direction is more difficult
With precise control, so the power acting on bearing can be generally divided into parallel to the removal force of electrical axis and perpendicular to motor
The component of axis.And the presence of component can make electric machine main shaft be subject to improper damage.
Meanwhile, when bearing to be removed is located at drive end axle head, existing horse is drawn cannot to use because motor-shaft extending is longer.
Content of the invention
The purpose of the present invention is for overcoming above-mentioned the deficiencies in the prior art, providing a kind of bearing extractor.The present invention is led to
Cross and design brand-new structure so as to can dismantle to the bearing being installed on high capacity motor.
In order to reach above-mentioned purpose, the present invention adopts the following technical scheme that：
A kind of bearing extractor, including：
There is the back timber of translot, the side of this back timber is fixedly connected with jack；
The both sides of described jack are respectively arranged with hook, and hook has multiple and described vertical the determining of axis
Position hole；
At least one positioning in the hole on arbitrary hook is provided with keeper.
Preferably, described back timber is also fixedly connected with suspension ring.
Preferably, described keeper is bolts and nuts.
Preferably, described location hole is screwed hole, and location hole and bolt form screw thread cooperation.
Preferably, described hook has hook part, and the inner side of hook part is had for putting down of being contacted with bearing internal external circle
Face.
While providing said structure scheme, present invention also offers a kind of utilization said apparatus dismantle the side of bearing
Method, mainly comprises the steps：
A, hang suspension ring using lifting device, this device is moved to the side of bearing to be removed；
B, the hook part of hook is adjacent to bearing side, and keeper is installed in location hole；
C, make the piston rod of jack align electric machine main shaft, then make piston rod stretch out, with electric machine main shaft end contact；
D, persistently make piston rod extend, then move after back timber and hook synchronization, bearing is disassembled.
It is preferred that before not carrying out step B after completing step A, heat treated is carried out to bearing in above-mentioned method.
In above-mentioned method it is preferred that in stepb, keeper is hex bolts and hex nut, and described hexagonal
Bolt is contacted with back timber with the pane of hex nut.
The invention has the beneficial effects as follows：
(1) hook spacing can adjust in translot consistent as bearing width.Make this device for different-diameter
All applicable for bearing.
(2) hook has planar portions, can fit tightly with the planar portions of bearing internal external circle it is ensured that hook dismounting before axis
Parallel with electrical axis so that hook in moving process, bearing is not applied other directions in addition to axial thrust force point
Power is it is ensured that electric machine main shaft is not damaged by.

Specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
Embodiment：A kind of bearing extractor, its structure as Figure 1-3, including：
There is the back timber 1 of translot 3, the centre of back timber 1 is forced section 7, and forced section 7 is fixedly connected with jack 4, forced section
7 outside has suspension ring 3.The both sides of jack 4 are respectively arranged with hook 2, and the upper end of each hook 2 has multiple location holes 9,
The active length of claw hook 2 is made to possess adjustability.And the upper end of described hook 9 protrudes from back timber 1 through after translot 8.
Wherein, described hook 2 has hook part, and the inner side of this hook part is plane 10.
As a kind of structure, location hole 9 is preferably screwed hole, so ensures that securing member is easy for installation.
The method dismantling bearing using this device is as follows：
A, hang suspension ring 3 using lifting device, this device is moved to the side of bearing 6 to be removed；
B, using roasting, bearing 6 is heated so as to flatulence of heat type；
C, the plane 10 of hook 2 is adjacent to the lower surface of bearing 6, and hex bolts is installed in location hole, use hexagonal
Nut fastens, and guarantees that the side of bolt and nut is contacted with forced section 7 simultaneously；
D, the piston rod of jack 4 is made to align electric machine main shaft it is ensured that the axis weight of the axis of jack 4 and electric machine main shaft 5
Close, then make piston rod stretch out, with electric machine main shaft end contact；
E, piston rod is persistently made to extend, it is motionless that motor maintains static then electric machine main shaft, and moves after back timber 1 and hook 2 synchronization,
Bearing 6 is just disassembled.
After employing said structure, using this device rely on 1-2 people can within half an hour will and bearing removal.With respect to
For artificial unloading, greatly save manpower and improve work efficiency.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.
