Specifically, the spherical groove 402 of the spherical surface hill 501 and spacer pad rear end that are oriented on jackscrew matches, so that
Guiding 5 front end of jackscrew can more securely withstand the rear end of spacer pad 4, and the movement of guiding jackscrew 5 is more directly had
It is transmitted to spacer pad 4 to effect and drives spacer pad 4 mobile.
In some optional embodiments, guiding jackscrew 5 includes:
It is provided with externally threaded jackscrew thread segment 502, the conduit wall in channel 302 includes setting internal thread channel screw thread
Section, jackscrew thread segment 502 are threadedly coupled to channel thread segment.
Jackscrew thread segment 502 is threadedly coupled to channel thread segment, so as to establish one between guiding jackscrew 5 and fixed bracket 3
Kind connects each other, generates and is closely threadedly coupled.
In some optional embodiments, it is oriented to jackscrew 5 further include:
The rear end of guiding jackscrew 5 is arranged in, suitable for being clamped by tool with rotary steering jackscrew 5 in six square toes 503.
Six square toes 503 of 5 rear end of jackscrew setting are oriented to, are matched with tools such as such as spanners, so that disassembly personnel can be with
By tools such as spanners come convenient controllably rotation guiding jackscrew 5.
In some optional embodiments, clutch extracting tool further include:
The front end of spacer pad 4 is arranged in detachable protective cap 6, the circular conical surface of the front end for protecting spacer pad 4
Interface thread 3011 on the outer circle wall of protrusion 401 and interface 301.
Since the circular conical surface protrusion 401 of 4 front end of spacer pad needs the circular conical surface with 1 spindle nose end face of combustion engine turbine output shaft
Groove 101 matches, and shape needs complete complementary, higher to workpiece shapes required precision, and manufacture craft is complex, and fixed branch
Interface thread 3011 on the outer circle wall of the interface 301 of 3 front end of frame is also easy to be worn when not in use, therefore does not make
It is protected, is avoided well due to circular conical surface protrusion 401 using dedicated protective cap 6 with when clutch extracting tool
Damage and cause the structural failure of 1 spindle nose of combustion engine wheel output shaft, and as interface thread 3011 damage and caused by backrest
The structural failure for taking turns screw thread 201, protects the structure and performance of combustion engine wheel output shaft 1 and clutch 2.
In some optional embodiments, protective cap 6 further include:
The front end of protective cap 6 is arranged in center conical hole 601, for cooperating the circular conical surface protrusion of 4 front end of spacer pad
401。
Cap thread 602 is protected, is arranged on the inner peripheral wall of 6 rear end of protective cap, mating interface screw thread 3011 is used for.
Specifically, it is cylindrical hole which, which is a half, and half is the combination hole of round taper hole,
So that protective cap 6 is tightened on fixed 3 front end of bracket using protection cap thread, and protective cap 6 covers the front end in spacer pad 4
When, the bottom of circular conical surface protrusion 401 can be stuck on round taper hole, the tip of circular conical surface protrusion 401 can vacantly in cylindrical hole,
Any inner wall of cylindrical hole is not contacted, causes any possibility to avoid tip of the center conical hole 601 to circular conical surface protrusion 401
Damage, preferably protect circular conical surface protrusion 401.
Protective cap 6 is a cylindrical cover shape block, and rear inside periphery is provided with protection cap thread 602, the protective cap spiral shell
Line 602 and the formation of interface thread 3011 are threadedly engaged, when not using clutch extracting tool, by clutch extracting tool from leaning on
It is removed on backgear 2, interface 301 is screwed in protective cap 6 and is screwed, and guiding jackscrew 5 is screwed, so that 4 front end of spacer pad
Circular conical surface protrusion 401 enters in center conical hole 601 and center conical hole 601 is bonded, can be by clutch extracting tool and guarantor
Helmet 6 is whole to be stored to storehouse.
In application, clutch extracting tool provided by the utility model dismantles lower combustion gas from the output shaft 1 of gas turbine
The concrete principle for taking turns the clutch 2 of pusher side is as follows: clutch extracting tool includes fixed bracket 3, spacer pad 4 and guiding jackscrew
5, when guiding jackscrew 5 rotates clockwise or counterclockwise, after withstanding spacer pad 4 due to the front end of guiding jackscrew 5
End, the front end of spacer pad 4 withstands the spindle nose of output shaft 1, so guiding jackscrew 5 and spacer pad 4 and output shaft 1 this three
It keeps opposing stationary, but since what is formed between guiding jackscrew 5 and fixed bracket 3 is threadedly engaged, is oriented to the rotation meeting of jackscrew 5
The reversed fixed bracket 3 of drive is for guiding jackscrew 5 and spacer pad 4 and output shaft 1 along axial direction to far from output shaft 1
Direction it is mobile, and the front end for fixing bracket 3 utilizes interface 301 and clutch 2 to connect, so the movement of fixation bracket 3
It will pull clutch 2 and moved along axial direction to the direction far from output shaft 1, clutch 2 is then made to be detached from output shaft 1.To real
On the basis of the structure to clutch 2 and performance do not generate any influence now, conveniently and efficiently from the output shaft of gas turbine
Upper 1 dismantles the clutch 2 of lower gas turbine side.
The above is merely for convenience of it will be understood by those skilled in the art that the technical solution of the utility model, not to
Limit the utility model.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
