Damage.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is present invention heating bearing status diagram；
Fig. 2 is that the present invention extrudes lower side bearing schematic diagram；
Fig. 3 is bearing arrangement schematic diagram of the present invention.
Specific embodiment
In order to illustrate more clearly of technical solution of the present invention, attached drawing needed in description will be made below simple
Ground introduction, it should be apparent that, drawings in the following description are only some embodiments of the invention, for ordinary skill
For personnel, without creative efforts, it can also be obtained according to these attached drawings other embodiments.
It is as shown in Figure 1, Figure 2, Figure 3 shows:
Present embodiment includes dismantlement work platform, hydraulic package, coil heats equipment, disassembly Anchor plate kit, tooling
Backing plate etc..
Dismantlement work platform is made of tooling top plate 5, tool base plate 9, tooling cushion block 8, long bolt 3, nut 4.Long bolt 3 divides
Other spiral shell, which is set, to be fixedly attached on tooling top plate 5 and tool base plate 9；The quantity of long bolt 3 at least there are four, tooling top plate 5 uses position
Nut 4 in top is screwed down contact and fixes；A frame structure is formed in this way.Tooling cushion block 8 is placed in tool base plate 9,
Notch 81 is placed in upward in tool base plate 9, and the diameter of notch 81 is greater than the diameter of bearing 10 and is less than planetary gear outer diameter, tooling
The notch 81 of cushion block 8 is used to receive the bearing 10 under disassembly.
Hydraulic package includes fixed housing 6, bolt 1, nut 2, hydraulic cylinder 15 and hydraulic pump unit (not embodying in attached drawing).
Fixed housing 6 is located at 5 lower section of tooling top plate, after connected bolt 1 passes through the through-hole of tooling top plate 5, with 5 top of tooling top plate
Nut 2 screw and be fixedly attached on tooling top plate 5.Hydraulic cylinder 15 is connected on fixed housing 6 by holding screw 7.Institute
It states hydraulic cylinder 15 and carries eyenut 17, there is self-locking function, load safer.The connector and hydraulic pump unit of hydraulic cylinder 15 connect
It connects.In this way, completing the assembly of whole dismounting workbench and hydraulic package.
Upside bearing inner ring a, the roller b of planetary gear 14 and the cone spacer d of centre are taken out, planetary gear 14 is placed in tooling
81 top of notch of cushion block 8.
Coil 16 is intensively wrapped in outside planetary gear 14, is heated and is gone using coil heats controller (not embodied in attached drawing)
Star-wheel 14 removes coil 16 after the completion of heating.
Dismantling Anchor plate kit includes subdivision pressing plate 11, double threaded screw 12.Double threaded screw 12 respectively with two subdivision pressing plates 11
Spiral shell is set in the screw hole of two subdivision pressing plates 11 of two sides respectively at the both ends of assembling namely double threaded screw 12, and can be adjusted
The centers of two subdivision pressing plates 11 is saved away from disassembly Anchor plate kit is contracted to minimum dimension.When installing and dismounting Anchor plate kit, double end
12 both sides screw thread of screw rod it is oppositely oriented, need to be corresponding with the screw hole rotation direction of subdivision pressing plate 11, the identical ability of rotation direction is mountable.
Then two subdivision pressing plates 11 are pressed respectively against on the outer ring of lower side bearing 10 of planetary gear 14.
Subdivision pressing plate 11 has step structure towards the direction of lower side bearing 10, and step structure is fastened on lower side bearing 10
The top edge of inner ring, the top of step structure are pressed on lower side bearing 10, and the inner ring and and inner ring of lower side bearing 10 are inserted into lower part
Cooperation, so that subdivision pressing plate 11 can be by the support of lower 10 inner ring of side bearing when two subdivision pressing plates 11 are under pressure, it can
It is destroyed to avoid being bent downwardly from the centre of two subdivision pressing plates 11.
When hydraulic cylinder travel is inadequate, since hydraulic cylinder 15 cannot directly work on disassembly component, for different
NNCF series planet wheel bearing 10, the centre for the Anchor plate kit that can be formed in hydraulic cylinder 15 and subdivision pressing plate 11, double threaded screw 12
Mounting tool backing plate 13.
It can need to be multiple according to the stroke accommodating tool backing plate 13 of hydraulic cylinder 15, the quantity of tooling backing plate 13.
After all toolings install, start hydraulic pump unit, 15 stress of hydraulic cylinder moves downward, and passes through 13 He of tooling backing plate
Downward power is transmitted on the outer ring of lower side bearing 10 by disassembly Anchor plate kit, thus side bearing 10 under safe and reliable extrusion.
Lower side bearing 10 is fallen into notch 81.
Upside bearing outer ring c need to overturn planetary gear 14 when dismantling, also with hydraulic cylinder 15 and disassembling fixture component, downwards
Extrude bearing outer ring c.
So far, planet wheel bearing can be extruded all.It should be noted that after heating planetary gear 14 with coil 16, Ying He
In due course interior installing and dismounting Anchor plate kit and tooling backing plate 13, to guarantee in bearing hole expanded by heating but bearing outer ring is not heated
When, bearing is extruded using hydraulic cylinder safety and nondestructive.
Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other
The difference of embodiment, the same or similar parts in each embodiment may refer to each other.To the upper of the disclosed embodiments
It states bright, enables those skilled in the art to implement or use the present invention.Various modifications to these embodiments are to ability
Will be apparent for the professional technician in domain, the general principles defined herein can not depart from it is of the invention
In the case where spirit or scope, realize in other embodiments.Therefore, the present invention be not intended to be limited to it is shown in this article these
Embodiment, and it is to fit to the widest scope consistent with the principles and novel features disclosed herein.
