Currently, removing load limiting type of constant filling fluid coupling usually using dismantling screw, that is, utilize load limiting type of constant filling fluid coupling main shaft
Swivel nut ad hoc on end is dismantled, top is screwed in by dismantling screw and arrives motor shaft or speed reducer shaft end, by load limiting type of constant filling fluid coupling
Under being pushed up from motor shaft or reductor shaft.But exist first is that the high difficulty of processing of swivel nut accuracy of screw machining requirement is big, quality is difficult
Guarantee, swivel nut, dismantling screw are threadedly engaged that precision is not high, and frictional resistance is larger, and the intensity of screw thread is inadequate, easily lead to screw thread damage
It is bad；Second is that disassembly is inconvenient, for fixed motor shaft or reductor shaft, electric motor fan shield need to be first removed, then remove fan leaf
Piece.
When no swivel nut or damage, old load limiting type of constant filling fluid coupling can not be removed, disassembly can only be damaged, cannot overhauled multiple
With not only causing certain economic loss, more seriously delay normal production.
Summary of the invention
The purpose of the utility model is to provide a kind of load limiting type of constant filling fluid coupling main shafts to dismantle distance-limiting type liquid of the end without swivel nut
Couple clutch provision for disengagement.
The utility model, which adopts the following technical scheme that, realizes its goal of the invention, a kind of load limiting type of constant filling fluid coupling disassembly
Device, it includes hydraulic cylinder, and hydraulic cylinder is equipped with the expansion mechanism for including swelling relief valve, swelling piston, swelling pawl, packet
Include the ejecting mechanism of ejection relief valve, ejection piston, mandril；The swelling pawl is mounted on hydraulic cylinder, outside swelling piston
Coupled between surface and the inner surface of swelling pawl by being segmented wedge-shaped conical surface Tenon, mandril passes through swelling piston, ejection piston simultaneously
It is connect with ejection piston thread.
The frictional force of end inner hole inner wall, the outer surface processing of the utility model swelling pawl are dismantled to increase swelling pawl and main shaft
There is anti-skidding stria.
When to prevent operation, hydraulic cylinder slides from load limiting type of constant filling fluid coupling, connects on the utility model hydraulic cylinder
It is connected to safety rope.
Due to the adoption of the above technical scheme, the utility model preferably realizes goal of the invention, and structure is simple, and operation makes
With convenient, and pulling force is big, to load limiting type of constant filling fluid coupling when realizing load limiting type of constant filling fluid coupling main shaft disassembly end without swivel nut
Disassembly.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the prior art；
Fig. 2 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and embodiments.
As shown in Figure 1, currently, removing load limiting type of constant filling fluid coupling 2 usually using dismantling screw 5, that is, distance-limiting type liquid is utilized
2 main shaft of couple clutch dismantles swivel nut 3 ad hoc on end, screws in top by dismantling screw 5 and arrives motor shaft 1 or speed reducer shaft end, will
Under load limiting type of constant filling fluid coupling 2 is pushed up from motor shaft 1 or reductor shaft.But exist first is that 3 accuracy of screw machining requirement of swivel nut
High difficulty of processing is big, and quality is difficult to guarantee, and swivel nut 3, dismantling screw 5 are threadedly engaged that precision is not high, and frictional resistance is larger, screw thread
Intensity is inadequate, easily leads to thread damage；Second is that disassembly is inconvenient, for fixed motor shaft 1 or reductor shaft, motor wind need to be first removed
Fan protective cover, then remove fan blade.
When no swivel nut 3 or damage, old load limiting type of constant filling fluid coupling 2 can not be removed, disassembly can only be damaged, cannot be overhauled
Multiplexing, not only causes certain economic loss, more seriously delays normal production.
As shown in Figure 2, a kind of load limiting type of constant filling fluid coupling provision for disengagement, it includes hydraulic cylinder 9, is set on hydraulic cylinder 9
Have including swelling relief valve 11, swelling piston 7, swelling pawl 6 expansion mechanism, including ejection relief valve 14, ejection piston 13, top
The ejecting mechanism of bar 10；The swelling pawl 6 is mounted on hydraulic cylinder 9, the outer surface of swelling piston 7 and the interior table of swelling pawl 6
By being segmented wedge-shaped conical surface Tenon connection between face, mandril 10 pass through swelling piston 7, ejection piston 13 and with ejection 13 spiral shell of piston
Line connection.
The frictional force of 4 inner wall of end inner hole, the outer surface of the utility model swelling pawl 6 are dismantled to increase swelling pawl 6 and main shaft
It is machined with anti-skidding stria 8.
When to prevent operation, hydraulic cylinder 9 slides from load limiting type of constant filling fluid coupling 2, the utility model moment-limited hydraulic
Safety rope 12 is connected between coupling device 2, hydraulic cylinder 9.
When being applied to the disassembly of load limiting type of constant filling fluid coupling, it includes the following steps: the utility model
(1) select the swelling pawl 6 to match with the main shaft of load limiting type of constant filling fluid coupling 2 disassembly end inner hole 4, by swelling pawl 6 with it is swollen
Tight piston 7 protrudes into main shaft disassembly end inner hole 4, passes through segmentation wedge shape between the outer surface of swelling piston 7 and the inner surface of swelling pawl 6
The connection of conical surface Tenon；Hydraulic tube is connected to swelling piston end, is pressurizeed by hydraulic hand-pump, and swelling piston 7 is mobile, makes swelling pawl 6
Provision for disengagement including hydraulic cylinder 9 is mounted on load limiting type of constant filling fluid coupling 2 by outside swelling；To increase swelling pawl 6 and master
Axis dismantles the frictional force of 4 inner wall of end inner hole, and the outer surface of the utility model swelling pawl 6 is machined with anti-skidding stria 8；Again by hydraulic cylinder
Body 9 is fixed on 2 flange bolt of load limiting type of constant filling fluid coupling by safety rope 12, prevents hydraulic cylinder 9 from moment-limited hydraulic idol
It is slid in clutch 2.
(2) swelling relief valve 11 is closed, its pressure is kept；Mandril 10 is screwed in into top to electricity by ejection 13 internal screw thread of piston
Then hydraulic tube is connected to ejection piston end, is pressurizeed by hydraulic hand-pump by machine or speed reducer shaft end, ejection piston 13 and top
Bar 10 is mobile, moves backward load limiting type of constant filling fluid coupling 2, when reaching ejection 13 stroke of piston, unclamps ejection relief valve 14,
So that ejection piston 13 is returned to initial position, then mandril 10 is screwed in, makes the top to motor or speed reducer shaft end of mandril 10；Again plus
Pressure, reciprocating operation, until load limiting type of constant filling fluid coupling 2 is removed from motor or reductor shaft；Ejection relief valve 14 is unclamped, is made
Ejection piston 13 returns to initial position；Safety rope 12 is unlocked again.
(3) hydraulic tube is connected to swelling piston end, 11 pressure release of swelling relief valve makes swelling piston 7 return to initial position；It is swollen
Tight pawl 6 unclamps, and removes the provision for disengagement including hydraulic cylinder 9, completes the dismantlement work of load limiting type of constant filling fluid coupling 2.
The provision for disengagement structure of the utility model is simple, easy for operation, and pulling force is big, realizes moment-limited hydraulic idol
