Also there is on anchor ring bar shaped tooth.
Torque amplification 7 is again torque multiplier, can be the torque amplification of known multiple applicable structure；This enforcement
In example, referring specifically to shown in Fig. 3, the preferably torque multiplier of aviation specialty；Torque amplification 7 is coaxially fixed on bracing frame 2
Decompose the end, one end of ring 1 away from assembling, and be set in outside tooth axle 5, the inner ring surface of torque amplification 7 has bar shaped
Tooth.Wherein, torque amplification 7 can be fixed with bracing frame 2 in several ways, is originally in embodiment, bracing frame 2 small-bore
Offering at least one groove on end end face, on torque amplification 7, one end end face near bracing frame 2 is provided with and groove phase
At least one projection joined, realizes torque amplification 7 and bracing frame 2 consolidating in rotation direction by groove with coordinating of projection
Fixed.
It addition, generally torque amplification 7 also has the matched moment size torque spanner that can show (not
Illustrate), in torque amplification 7 side, (top end face of Fig. 1) has the joint portion matched with torque spanner, in conjunction with after pass through power
Square spanner driving torque amplifier 7；Assembling is decomposed the applying of moment of torsion and is realized by torque spanner, can pass through torque spanner
The moment size of display and the moment of torsion amplification of device are assembled decomposition moment of torsion accurately, it is achieved that the assembling to baffle plate divides
The real-time monitoring of the moment of torsion in solution preocess；Meanwhile, the torque value obtained in assembling catabolic process, can design for engine structure
Personnel provide reference, contribute to the Optimized Improvement Design of this structure.
Set tooth group section 8 cylindrically, is arranged between set tooth axle 5 and torque amplification 7, inner ring surface has and set tooth
The bar shaped tooth that on axle 5 other end outer ring surface, bar shaped tooth matches, outer ring surface has and bar shaped tooth on torque amplification 7 inner ring surface
The bar shaped tooth matched.
Axial load nut 9 is arranged on the end, one end decomposing ring 1 away from assembling of axial load pull bar 4, carries out screw thread
It is connected；And axial load nut 9 external diameter is more than set tooth axle 5 internal diameter, and against to set tooth axle 5 end.
The attaching/detaching apparatus of the high-pressure turbine front apron of the present invention, by the amplification to moment of torsion, it is achieved that to front apron
The stable loading of required torque is decomposed in assembling, it is to avoid the damage that parts are caused by shock loading, also eliminates impact simultaneously and carries
The sense of discomfort that operator are caused by the counteracting force effect of lotus.
The attaching/detaching apparatus of the high-pressure turbine front apron of the present invention can also include bearing baffle 21, circular side plate 10 and
Distance rod 11.
Bearing baffle 21 is arranged on one end decomposing ring 1 away from assembling of bracing frame 2, is used for thrust ball bearing 6 at axle
Limit to the displacement in direction, thus add stiff stability.
Side plate 10 is set on the bar shaped tooth of one end outer ring surface decomposing ring 1 away from assembling of tooth axle 5, and side plate 10 is straight
Footpath, more than the internal diameter of torque amplification 7, can add stiff stability equally, and torque amplification 7 plays the limit on axis direction
Position effect.
Distance rod 11 includes at least one, and its one end is fixed on assembling and decomposes on ring 1, the axial line of distance rod 11 and assembling
Decompose ring 1 place plane parallel, and pass perpendicularly through the axial line of assembling decomposition ring 1, for being applied the work of power by distance rod 11
With, prevent assembling from decomposing ring 1 and rotate.In the present embodiment, distance rod 11 is two, and it is right to decompose centered by the center of circle of ring 1 by assembling
Claim distribution.
The attaching/detaching apparatus of the high-pressure turbine front apron of the present invention, mainly by moment of torsion amplification principle, by defeated to stablizing
The moment of torsion entered is amplified, and the moment of torsion after amplifying is respectively acting on front apron and the turbine disk, forms positive twist between
Square and reaction torque effect, it is achieved both relatively rotate, thus reach front apron assembling on the turbine disk and decompose purpose.
The installation of the attaching/detaching apparatus of the high-pressure turbine front apron of the present invention and the process of use approximately as:
First, before connecting fixed part 31 and the high-pressure turbine dish of seat 3, the arc end flank of tooth is attached fixing by bolt,
For the moment of torsion that set tooth axle 5 transmits is passed to high-pressure turbine dish；Run through on the through hole of fixed part 31 and have axial load pull bar
4, in order to produce axial load.
Secondly, assembling is decomposed ring 1, bracing frame 2, set tooth axle 5, thrust ball bearing 6 and bearing baffle 21 to fill successively
Joining, the assembly of formation is lifted into the cooperation position of front apron；Regulation set tooth axle 5 axial location, in order to connect seat 3 and be coupled to
Position；Adjustment assembly decomposes ring 1 circumferential position, it is ensured that fit completely in its side with the boss of front apron.
Again, torque amplification 7 and set tooth group section 8 are installed, during set tooth group section 8 is installed, need suitably to turn
The input of dynamic torque amplifier 7, in order to set tooth group section 8 is installed to overlap between tooth axle 5 and torque amplification 7 smoothly；Then
After checking that each several part installation puts in place, tighten axial load nut 9, and need the axial deformation ensureing front apron boss to meet dress
Partition solution requirement.
During use, first pass through and tighten axial load nut 9 so that axial load pull bar 4 upwards (regards with reference to shown in Fig. 1
Figure direction) move a certain distance, thus drive the connection seat 3 being fixedly connected and high-pressure turbine dish to move axially, now high pressure
Turbine front apron is motionless relative to high-pressure turbine dish under the supporting role of bracing frame 2；Therefore, finally make high-pressure turbine dish with
Produce a displacement between high-pressure turbine front apron in the axial direction, thus produce axial load；Above-mentioned tighten axial load
The main purpose of nut 9 step, is to ensure that the axial deflection of the boss of front apron meets assembling and decomposes requirement.
On the basis of creating axial load between above-mentioned high-pressure turbine dish and high-pressure turbine front apron, moment is utilized to pull
Hands coordinates with torque amplification 7, input action moment, applies moment by distance rod 11 simultaneously, prevents assembling from decomposing ring 1；From
And utilize the moment of torsion after amplification to make high-pressure turbine dish and high-pressure turbine front apron relatively rotate (clockwise or counterclockwise),
Realize the assembling to front apron or decomposition.It addition, need to give much attention to the size of moment in the process, it is to avoid moment transfinites right
Parts and device cause damage, the most also need to record whole during moment variations situation, for follow-up related process and design
Work provides reference.
The above, the only detailed description of the invention of the present invention, but protection scope of the present invention is not limited thereto, and any
Those familiar with the art in the technical scope that the invention discloses, the change that can readily occur in or replacement, all answer
Contain within protection scope of the present invention.Therefore, protection scope of the present invention should be with described scope of the claims
Accurate.
