Description
Technical field
The utility model relates to a kind of large size bearing provisions for disengagement, belong in seawater filtering system, to during maintenance of equipment
Provision for disengagement to super large diameter bearing.
Background technique
There are many seawater filtering system type at present, and drum type filter screen is one of.Drum type filter screen is one and circumferentially fills
There is the rotational circle cylinder of mesh sheet, seawater enters drum net inside from both sides of the face, tiny micro- less than 3mm by wire side filter diameter
After biological and other impurity, circumferentially outer water outlet, crossing drainage includes the cooling water etc. for being supplied to nuclear power system.The equipment needs
Long time running is wanted, once failure, influences the offer of nuclear reactor cooling water, is easy to appear accident.
Drum type filter screen is global facility, and including drum net spindle mounted, spindle mounted is placed on bearing housing by two
Super large bearing support the rotation of entire drum type filter screen, the disassembly in the two super large bearing later periods and the arduous task of maintenance,
It not only dismantles time-consuming and laborious, but also be easy to cause damage of the bearing in disassembly process, directly contribute property loss.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of large size bearing provision for disengagement, large size bearing disassembly dresses
The efficiency for not only improving disassembly bearing is set, but also can guarantee the nondestructive demounting of bearing, saves maintenance cost.
In order to solve the above problem, the specific technical solution of the utility model is as follows: a kind of large size bearing provision for disengagement, in axis
The outer ring excircle held is symmetrical arranged several removal rods, and the length of removal rod is equal to the height of bearing, in one end of removal rod
Equipped with L-type crimp, the surface of L-type crimp is contacted with bearing outer ring end face；It is equipped with and tears open in the bearing housing inner surface of Bearing outer
The corresponding groove in bar position is unloaded, removal rod is completely embedded into groove；Internal screw thread, spiral shell on internal screw thread are equipped in the other end of removal rod
Line connects force rod, and force rod is supported on disassembly frame body, and stress boom end is equipped with nut, and nut will dismantle frame by force rod
Body is pressed on the end face of bearing housing.
The structure of the disassembly frame body is that adding for circumference uniform distribution is arranged in the skirtboard of circumference setting on the end face of skirtboard
Standing screw is arranged in strong plate in stiffening plate, and the end of standing screw is connect with the intrinsic threaded hole in bearing housing end, stress
Bar is pierced by from the stiffening plate of corresponding position, and end attaching nut.
The large size bearing provision for disengagement uses the disassembly rod structure of bearing housing built-in type, and by force rod to removal rod
Apply external force, to guarantee that the disassembly of super large diameter bearing is time saving and energy saving, while also be able to achieve with the whole outer shifting of dynamic bearing
The nondestructive demounting of bearing, protects bearing not to be destroyed.
The structure that frame body uses skirtboard and stiffening plate is dismantled, not only overall structure is simple, and manufacturing cost is low, and maintenance side
Just.
Detailed description of the invention
Fig. 1 is large size bearing provision for disengagement entirety schematic view of the front view.
Fig. 2 is large size bearing provision for disengagement entirety overlooking structure diagram.
Fig. 3 is large size bearing provision for disengagement entirety side structure schematic view.
Specific embodiment
As shown in Figure 1 to Figure 3, a kind of large size bearing provision for disengagement is symmetrical arranged several in the outer ring excircle of bearing
Removal rod 5, the length of removal rod 5 are equal to the height of bearing, are equipped with L-type crimp, the surface of L-type crimp in one end of removal rod 5
It is contacted with bearing outer ring end face；Groove corresponding with 5 position of removal rod, disassembly are equipped in 7 inner surface of bearing housing of Bearing outer
Bar 5 is completely embedded into groove；It is equipped with internal screw thread in the other end of removal rod 5, is threadedly coupled force rod 4, force rod 4 on internal screw thread
It is supported on disassembly frame body, 4 end of force rod is equipped with nut 6, and nut 6 is pressed on bearing housing 7 for frame body is dismantled by force rod 4
End face on.
The structure of the disassembly frame body is that circumference uniform distribution is arranged in the skirtboard 1 of circumference setting on the end face of skirtboard 1
Stiffening plate 2, is arranged standing screw 3 in stiffening plate 2, and the intrinsic threaded hole in end and bearing housing end of standing screw 3 connects
It connects, force rod 4 is pierced by from the stiffening plate 2 of corresponding position, and end attaching nut 6.
The course of work of the large size bearing provision for disengagement are as follows: during maintenance of equipment, when removing bearing if necessary, will fix
Screw rod 3 is fixed on bearing housing 7, and wherein removal rod is embedded between bearing and bearing housing during spindle mounted, after being
The use of phase provides convenient；Then force rod 4 is connect with removal rod 5, by the nut 6 on rotation force rod 4, can be pulled
Removal rod 5, band dynamic bearing moves horizontally outward, until bearing is all detached from bearing housing.Wherein skirtboard, stiffening plate can pass through
The method of machining and welding processing is realized.The device overcomes the puzzlement of the bad disassembly of super large bearing, using simple and effective
Design principle generates transverse shifting, is a kind of special bearing disassembling device by the rotation of screw thread.
