Description
Technical field
The invention belongs to aero-engine mounting technology fields, and in particular to a kind of aero-engine spline housing gear coupling
Assemble device and method.
Background technology
Spline housing gear coupling structure is widely used in the industry because number of parts is few, structural reliability is high, light-weight.
But the assembly and disassembly of the structure is always in industry a technological difficulties.Because it needs to make spring during assembly and disassembly
[6] compressive state is constantly in, shaft end nut [4] detaches, while use large torque rotates with the mesh splines of neck bush [5] at this time
Shaft end nut [4] is tightened or is unscrewed.By taking the engine of medium thrust as an example, the torque generally 1000Nm~
Between 3000Nm.It is now more in industry that shaft end spiral shell is realized using device of the front end shown in Fig. 3 with spline and boss
The assembling and decomposition of female [4].The device is to realize that shaft end nut [4] engages flower with neck bush [5] by conducting oneself with dignity come compressed spring
The separation of key.But to detach reliability with the mesh splines of neck bush [5] not high for shaft end nut [4] in rotation process, is filling
With the quality accident that the destruction of spline housing gear coupling structure often occurs in decomposable process.Engine overhaul factory, engine manufacture
Enterprise is per the case that the several structural failures can occur every year.Because Aeroengine Industries have small, the spare part system of production batch
Make the features such as of high cost, the process-cycle is long, spare part storage is few, once recurring structure damage by greatly increase engine assembling,
Decompose the period.For in-service ordnance engine, serviceability rate that the extension of overhaul life will seriously affect military hardware, directly
Connect the fighting capacity for influencing the aviation arm of the services.In addition, existing method in assembling process because it cannot be seen that the circumferential direction of shaft end nut [4]
Position need to repeatedly attempt just make the spline of neck bush [5] smoothly to be popped up from shaft end nut [4] internal spline, therefore assemble effect
Rate is relatively low.
Spline housing gear coupling is the typical torsion pass structure of aero-engine, because its is simple in structure, safe and reliable, is used extensively
In the transmission of rotor torque.Fig. 2 is the spline housing gear coupling structure diagram of certain h type engine h, and rotor passes through inside and outside spline engagement
Torsion pass is carried out, axial limiting is carried out by the nut [4] of shaft end, passes through the interior of the external splines of neck bush [5] and shaft end nut [4]
Spline engagement is realized locking.Reliably make neck bush [5] under the action of spring [6] compression reaction power during engine work
With shaft end nut [4] always in meshing state, simple and reliable realizes torsion pass locking functions.
Invention content
The purpose of the present invention is：For the deficiency of existing aero-engine spline housing gear coupling mounting technology, the present invention
It is proposed the assembling device and process of a kind of brand new, it is ensured that structure shaft end nut in decomposable process is assembled

There is a cylinder latch structure in bolt component [3] tail portion, which installs into the groove of drive component [1],
Bolt component [3] can be free to slide along groove；Bolt component [3] head is mounted in the radial directed hole on housing unit [2],
Achievable bolt component reliably radially moves.
Contained in the housing unit [2] one can angles of display pointer, can show housing unit [2] rotation angle
Degree, and it is mounted remotely from one end of bolt component [3].
The spline structure close to bolt component [3] one end is further included, the spline structure passes through the flower on shaft end nut [4]
Key is engaged.Realize the function of assembly and disassembly shaft end nut [4].
A kind of aero-engine spline housing gear coupling assembly method, includes the following steps；
Step 1：Driving drive component [1] makes bolt component [3] positioned at least displacement state.
Step 2：It installs in the present apparatus to the shaft end nut [4] of engine, makes spline and shaft end spiral shell on housing unit [2]
Spline engagement on female [4].
Step 3：Neck bush [5] is compressed to least displacement state, and driving drive component [1] makes bolt component [3] positioned at most
Big displacement state, the angle value for recording pointer at this time are α.
Step 4：The present apparatus is rotated by the screw-down torque range that shaft end nut [4] gives, treats the angle value of pointerWhen, the shaft end nut that stops operating [4], wherein N is positive integer, and Z is the number of teeth of neck bush [5] spline.
Step 5：Driving drive component [1] makes bolt component [3] positioned at least displacement state.
Step 6：The lower device is decomposed from engine, neck bush [5] external splines is popped up from shaft end nut [4] internal spline
