It should be noted that the description of these examples is for aiding in understanding the present invention, but is not intended to limit the present invention.

Wherein, the aeroengine gear shaft bearing decomposition device forms an axial disassembly channel through the base 100 and the disc type claw 200, when the gear shaft 500 is mounted on the axial disassembly channel, the degree of freedom of the gear shaft 500 is limited and can only slide back and forth along the axial direction, so as to reduce the disturbance of the gear shaft 500 in the process of bearing 600 disassembly, and avoid secondary damage. External equipment is connected with the gear shaft 500 through the core rod 300, so that the gear shaft 500 is driven to slide unidirectionally along the axial direction, meanwhile, the bearing 600 is clamped by the disc-type clamping jaw 200, when the gear shaft 500 slides, the bearing 600 is kept relatively static, and relative movement occurs between the gear shaft 500 and the bearing 600, so that the gear shaft 500 and the bearing 600 are decomposed. In addition, due to the existence of the axial disassembly channel, the gear shaft 500 only slides along the axial direction, compared with the existing disassembly method, the probability of damaging the journal sealing surface of the gear shaft 500 is effectively reduced, and the gear shaft 500 and the bearing 600 are effectively protected.
The base 100 has the functions of circumferential and axial positioning, and meanwhile, the base 100 is provided with a supporting rod 101, and the supporting rod 101 can be used for connecting the disc type clamping jaw 200 and also defines the length of an axial decomposition channel. The disc-type claw 200 is detachably connected to the base 100, namely, the disc-type claw 200 is detachably connected to the supporting rod 101, and the disc-type claw 200 is provided with a bearing 600 which is positioned circumferentially and can be clamped; correspondingly, the inner ring of the bearing 600 is provided with a groove, and the disc-type claw 200 is inserted into the groove. It is easy to understand that when the disc-type claw 200 is mounted to the support rod 101, both ends of the axial decomposition passage are closed so as to perform the decomposition work; when the disk claw 200 is detached from the support rod 101, one end of the axial disassembly passage is opened to facilitate the disassembly and assembly of the gear shaft 500.
Optionally, the inner circumference of the core rod 300 is provided with a clamping groove adapted to the gear shaft 500, and the outer circumference of the core rod 300 is configured to be adapted to a connection surface of an external device, so that the core rod 300 effectively connects the gear shaft 500 with the external device, driving force of the external device can be effectively transmitted to the gear shaft 500, the driving force acts on the gear shaft 500 along the axial direction, dispersion of the driving force is reduced, and the gear shaft 500 and the bearing 600 are effectively protected.
In operation, the disc claw 200 is detached to open the axial disassembly passage, and the gear shaft 500 is inserted through the support rod 101 to be mounted to the base 100; the disc chuck 200 is connected to the support rod 101 so that the axial separation passage is closed, and care should be taken to allow the disc chuck 200 to be engaged with the bearing 600 when the disc chuck 200 is installed. A connecting core rod 300 and an external device are provided at the top of the gear shaft 500, and the external device is activated to drive the gear shaft 500 to move relative to the bearing 600, so as to separate the gear shaft 500 and the bearing 600.
It will be readily understood that, as shown in fig. 1, when one bearing 600 is provided at each end of the gear shaft 500, after one bearing 600 is disassembled according to the above steps, the external device, the core rod 300 and the disk claw 200 are disassembled, the gear shaft 500 is removed from the base 100 and is reversely mounted to the base 100, and then the disk claw 200, the core rod 300 and the external device are sequentially mounted again to disassemble the other bearing 600 on the gear shaft 500.
That is, the decomposing device for the gear shaft bearing of the aero-engine can decompose one bearing 600 at a time, and when a plurality of bearings 600 are arranged on the same gear shaft 500, the decomposing device for the gear shaft bearing of the aero-engine should be repeatedly disassembled and assembled for a plurality of times, so that all the bearings 600 are decomposed.
In this embodiment, the disc chuck 200 includes a disc body 201, a chuck body 202, and a retainer ring 203;
the tray body 201 is annular, the tray body 201 is provided with a first connecting hole 204 and a jaw groove 205, the first connecting hole 204 is provided with a plurality of jaw grooves 205 which are arranged in a one-to-one correspondence with the supporting rods 101, the jaw grooves 205 are provided with a plurality of jaw grooves 205 which are arranged at intervals in the circumferential direction of the tray body 201, two ends of the jaw grooves 205 are respectively communicated with the outside, correspondingly, the jaw bodies 202 are provided with a plurality of jaw grooves 205 which are arranged in a one-to-one correspondence with the jaw grooves 205, and the jaw bodies 202 are movably arranged in the corresponding jaw grooves 205;
the top surface of the tray body 201 is provided with a plurality of fixing grooves 206, the fixing grooves 206 are arranged in a one-to-one correspondence with the jaw grooves 205, and the fixing grooves 206 are communicated with the jaw grooves 205 and the outside; the limiting ring 203 is detachably disposed on the top surface of the tray 201, and the limiting ring 203 is connected to the jaw body 202 through a first connecting rod 207 penetrating through the fixing slot 206.
Based on the above design, the disc 201 is connected with the support rod 101 through the first connection hole 204, that is, the top of the support rod 101 is inserted into the first connection hole 204, so as to limit the circumferential freedom degree, and in view of the fact that the bearing 600 only slides along the axial direction when being disassembled, the circumferential disturbance is small, and the support rod 101 can selectively lock the disc 201. Alternatively, when the supporting rod 101 locks the tray 201, the top of the supporting rod 101 is configured as a screw, and the first connection hole 204 is configured as an adapted screw hole.
The jaw body 202 is used for clamping the bearing 600, so that the bearing 600 is kept relatively static when the gear shaft 500 slides, and the bearing 600 on the gear shaft 500 is disassembled. Since the size of the gear shaft 500 varies from the design value after the engine is manufactured and used, the jaw body 202 is movably disposed on the jaw groove 205. Based on this, the jaw body 202 has a certain adjustment space when mounted, so that the jaw body 202 has a recess on the inner ring of its bearing 600.
The stop ring 203 serves as a location to show where the disc dog 200 is located, helping a worker identify if the disc dog 200 is rotating in place. Meanwhile, the limiting ring 203 is fixed on the disc 201 through the first connecting rod 207, and the first connecting rod 207 passes through the fixing groove 206 and is connected with the jaw body 202, based on this, the first connecting rod 207 is simultaneously used for fixing the jaw body 202, so as to avoid disturbance of the jaw body 202 in the decomposition process, ensure that the bearing 600 is not disturbed, and protect the journal sealing surface of the gear shaft 500.
It is readily understood that the jaw body 202 may be configured in any suitable shape and the first connecting rod 207 includes, but is not limited to, screws, bolts and bolts.
In a possible implementation manner, the plurality of first connecting holes 204 are arranged at equal intervals in the circumferential direction of the disc 201, and the circumference where the first connecting holes 204 are located is located outside the limiting ring 203, and correspondingly, the supporting rod 101 is provided with a plurality of first connecting holes and is arranged at equal intervals in the circumferential direction of the base 100. Based on the above design, the first connecting holes 204 are uniformly distributed on the tray 201, and the supporting rods 101 are uniformly distributed on the base 100, so that the axial decomposition channel is uniform in structure and more balanced in stress when the axial decomposition channel is formed, thereby being beneficial to improving structural stability and service life.
Further, on the basis of ensuring the structural strength, the number of the supporting rods 101 can be arbitrarily increased or decreased, and accordingly, the number of the first connection holes 204 is increased or decreased synchronously.
In one possible implementation, the top surface of the tray 201 is provided with a handle 208 and a weight-reducing groove 209, where the handle 208 is provided in two and opposite positions, and the weight-reducing groove 209 is configured as an arc-shaped groove. Based on the above design, the grip point is increased by the handle 208, so that the disk claw 200 can be conveniently disassembled and assembled by a worker or related equipment; the weight of the tray 201 is reduced by the weight-reducing groove 209 to improve the convenience of movement of the tray claw 200.
In a possible implementation manner, the limiting ring 203 is provided with a plurality of second connecting holes and a grab handle 210, the second connecting holes are arranged in a one-to-one correspondence with the jaw bodies 202, the first connecting rods 207 penetrate through the jaw bodies 202 and the fixing grooves 206 and are connected with the second connecting holes through threads, and correspondingly, the first connecting rods 207 are provided with external threads, and the second connecting holes are configured as threaded holes; the handles 210 are provided in two and oppositely disposed on the top surface of the retainer ring 203.

The grip 210 facilitates movement of the stop collar 203 by a worker or associated equipment to effect disassembly and assembly of the stop collar 203, and alternatively, the grip 210 may be configured in any suitable shape.
In the present embodiment, the base 100 includes a base 102, a top cylinder 103 and an outer cylinder 104, the top cylinder 103 and the outer cylinder 104 are provided in the middle of the base 102, the outer cylinder 104 is coaxial with the top cylinder 103 and is located outside the top cylinder 103, and the height of the top cylinder 103 is greater than the height of the outer cylinder 104.
