Specific embodiment
The embodiments described below with reference to the accompanying drawings are exemplary, for explaining only the invention, and cannot be construed to
Limitation of the present invention.
As shown in Figures 1 to 4, the embodiment provides one kind for disassembling gearbox shafting rear end L-type needle roller
The disassembling apparatus of bearing insert, comprising:
The top of pressure head 1, the pressure head 1 is connect with pressing piece, and the type of pressing piece not limits in the present embodiment, can
The various ways such as mo(u)ldenpress, handpress or manpower are selected, as long as can apply continual and steady lower pressure makes L-type bushing
14 can be detached from from axis.
Cylinder 2, the top of the cylinder 2 are connect with the bottom end of the pressure head 1, successively shape from top to bottom in the cylinder 2
At having the first slot section 3 and the second slot section 4 that are connected, the internal diameter of the first slot section 3 is greater than the internal diameter of the second slot section 4,
The second slot section 4 runs through the bottom end of the cylinder 2, and tapered roller bearing 15 is accommodated in the first slot section 3, the bottom of cylinder 2
End end face be ring structure, press on L-type bushing 14, pressure head 1 with by the pressure conduction of pressing piece to cylinder 2, thus by L-type
Bushing 14 is deviate from.
The cylinder 2 is by symmetrically arranged left semicircle plate 5 and right semi-circle plate 6 is detachable is spliced, and is installing in this way
When this disassembling apparatus, 15 outer ring of tapered roller bearing of shaft end can be avoided open.
Before being disassembled, first cylinder 2 is dismantled as 6 two parts of left semicircle plate 5 and right semi-circle plate, by left semicircle plate 5
It is assemblied on axis with right semi-circle plate 6, tapered roller bearing 15 is accommodated in 3 part of the first slot section, at this time left semicircle plate 5 and right half
The bottom end face of plectane 6 is resisted against the upper surface of L-type bushing 14, and left semicircle plate 5 and right semi-circle plate 6 surround to form the cylinder 2,
Pressure head 1 is connect with cylinder 2 again, if cylinder 2 is not designed as detachable structure, 15 outer ring of tapered roller bearing will be formed
Interference.
Above-described embodiment can not only avoid the gear teeth tips on axis in dismantling while can avoid the circular cone of end
15 outer ring of roller bearing solves L-type bushing 14 in the prior art and is located at what shafting end can not be disassembled by shifting gear
Technical problem.
Further, the pressure head 1 includes pressing plate 7 and the button 10 that is fixed on the pressing plate 7, button 10 be used for
Press connection, the pressing plate 7 are kidney-shaped structure, and the diameter at the major diameter end of the pressing plate 7 and the top end diameter of the cylinder 2 are mutually fitted
It answers, the stability of cylinder 2 when improving press fitting can be preferably by the pressure conduction of press to cylinder 2, the minor axis of the pressing plate 7
Stepped groove 8 is symmetrically arranged on end.
There are two symmetrically arranged fixture block 9, the left sides for the equal projection in top surface of the left semicircle plate 5 and the right semi-circle plate 6
Two fixture blocks 9 on semi-circular plate 5 fit in two fixture blocks 9 on the right semi-circle plate 6 respectively, and the fixture block 9 is
Inverted l-shaped structure, 8 inlay card of stepped groove is between the fixture block 9 and the cylinder 2, so that pressure head 1 be connect with cylinder 2, fills
It with convenient, and is readily disassembled, when disassembly, only need to exert oneself for left semicircle plate 5 and right semi-circle plate 6 to be pulled horizontally off.
The cooperation of fixture block 9 and stepped groove 8 is avoided causes cylinder 2 to be flown by pressure in press fitting due to installation or pressure deflection
Safety problem, the binding effect of disassembling apparatus is when further increasing press fitting to improve the stability of disassembling apparatus.So that press fitting
When the mutual constraint by structure of left semicircle plate 5 and right semi-circle plate 6.
Further, during to improve dismantling, pressure head 1 can it is reliable and stable by pressure transmission to cylinder 2, avoid cylinder
2 pressures fly, and the first slot section 3 runs through the top of the cylinder 2, and the bottom surface of the pressing plate 7 is convexly equipped with pillar 11, the pillar 11
Outer diameter and the first slot section 3 internal diameter be adapted, pillar 11 play limit and improve stability action.
Further, jagged 12 are opened up on the side wall of the left semicircle plate 5, there are two the notch 12 is set, two institutes
It states notch 12 to be symmetrically set on the both ends side wall of the left semicircle plate 5, is convexly equipped on the side wall of the right semi-circle plate 6 and is lacked with described
Mouth 12 forms the protrusion 13 of inlay cards cooperation, and corresponding raised 13 also are provided with two, and protrusion 13 and notch 12 are used cooperatively, can
To prevent due to processing and manufacturing error and wear after being used for a long time the decline for leading to the restriction ability of 2 junction of pressure head 1 and cylinder,
Structure, feature and effect of the invention, the above institute are described in detail based on the embodiments shown in the drawings
Only presently preferred embodiments of the present invention is stated, but the present invention does not limit the scope of implementation as shown in the drawings, it is all according to structure of the invention
