Description
Technical field
The utility model relates to structural design and the application of cardan shaft assembly, provides especially a kind of for the aligning cross universal shaft assembly of horizontal tail steering wheel is installed.
Background technique
Crossed universal shaft is a kind of transmitting assemblies, for the power between two concurrent aceses or motion transmission.Due to simple in structure, reliable, working service convenience, and be widely used in all kinds of mechanical transmission.
The crossed universal shaft of application does not possess the function of adjustment axis relative position conventionally at present, in actual installation process, cannot compensate by the error of manufacturing, assembling produces like this.
People urgently wish to obtain a kind of cardan shaft assembly with aligning function.
Model utility content
The purpose of this utility model be to provide a kind of technique effect good for the aligning cross universal shaft assembly of horizontal tail steering wheel is installed.
Described as follows for the aligning crossed universal shaft module composition of horizontal tail steering wheel is installed: cardan shaft 1 and assembled shaft 2; The middle part of described cardan shaft 1 is round and smooth spheroid 11, two ends are the cylindrical structural 12 of axis on same straight line, on described round and smooth spheroid 11, be provided with the through hole I 13 of vertical cylinder body structure 12, described assembled shaft 2 is positioned at through hole 13, described cylindrical structural 12 is provided with orthogonal through hole II 14 vertically and radially, wherein in axial hole II 14, be provided with axle, the central axis Vertical direction distance L of the central axis of described cylindrical structural 12 and through hole I 13 is 1-5mm; Described through hole oil 13 ends are provided with stops up 15; Described aligning cross universal shaft assembly is positioned at horizontal tail steering wheel ear fork 3 and structural member bearing 4, and fixing by bearing (ball) cover 5,
In the middle of described assembled shaft 2 is specially, it is smooth bolt.
Two axles of described cardan shaft are respectively charged in the bearing in housing construction part two ear forks, and fix by bearing (ball) cover.Assembled shaft 2, through ear fork and the universal axis hole of horizontal tail steering wheel, is assembled by fastening pieces such as washer nuts.
In working procedure, horizontal tail steering wheel pressurized strut piston stretches out, regains and drives horizontal tail to rotate around horizontal tail macro-axis.Horizontal tail steering wheel and structure fixed block are by after aligning cardan shaft assembled, make horizontal tail steering wheel can realize the swing in plane of movement, be that horizontal tail steering wheel rotates around cardan shaft axle center together with cardan shaft, horizontal tail steering wheel can rotate around the assembled shaft of cardan shaft simultaneously, can compensate the horizontal tail steering wheel axis augular offset of manufacture, assembling generation, specifically referring to accompanying drawing 5.
But for the deviation between horizontal tail steering wheel two mounting points, cause horizontal tail rudder surface neutral position deviation, cannot regulate.Aligning cardan shaft assembly is one group of two cardan shaft assembly that axle center relative position is different, during assembling, by apolegamy, picks out the cardan shaft that can meet horizontal tail neutral position, installs.
Described simple for the aligning crossed universal shaft modular construction of horizontal tail steering wheel is installed, to manufacture easy for installationly, reliability is high, has good maintainability.Adopt this kind of aligning cardan shaft, horizontal tail steering wheel straight line motion can be converted into and rotate the plane motion combining with straight line motion, can compensate again and manufacture the error producing in assembly process, guarantee neutral position and the control surface deflection angle of horizontal tail.

Embodiment
Embodiment 1
Described as follows for the aligning crossed universal shaft module composition of horizontal tail steering wheel is installed: cardan shaft 1 and assembled shaft 2; The middle part of described cardan shaft 1 is round and smooth spheroid 11, two ends are the cylindrical structural 12 of axis on same straight line, on described round and smooth spheroid 11, be provided with the through hole I 13 of vertical cylinder body structure 12, described assembled shaft 2 is positioned at through hole 13, described cylindrical structural 12 is provided with orthogonal through hole II 14 vertically and radially, wherein in axial hole II 14, be provided with axle, the central axis Vertical direction distance L of the central axis of described cylindrical structural 12 and through hole I 13 is 1-5mm; Described through hole oil 13 ends are provided with stops up 15; Described aligning cross universal shaft assembly is positioned at horizontal tail steering wheel ear fork 3 and structural member bearing 4, and fixing by bearing (ball) cover 5,
In the middle of described assembled shaft 2 is specially, it is smooth bolt.
Two axles of described cardan shaft are respectively charged in the bearing in housing construction part two ear forks, and fix by bearing (ball) cover.Assembled shaft 2, through ear fork and the universal axis hole of horizontal tail steering wheel, is assembled by fastening pieces such as washer nuts.
In working procedure, horizontal tail steering wheel pressurized strut piston stretches out, regains and drives horizontal tail to rotate around horizontal tail macro-axis.Horizontal tail steering wheel and structure fixed block are by after aligning cardan shaft assembled, make horizontal tail steering wheel can realize the swing in plane of movement, be that horizontal tail steering wheel rotates around cardan shaft axle center together with cardan shaft, horizontal tail steering wheel can rotate around the assembled shaft of cardan shaft simultaneously, can compensate the horizontal tail steering wheel axis augular offset of manufacture, assembling generation, specifically referring to accompanying drawing 5.
But for the deviation between horizontal tail steering wheel two mounting points, cause horizontal tail rudder surface neutral position deviation, cannot regulate.Aligning cardan shaft assembly is one group of two cardan shaft assembly that axle center relative position is different, during assembling, by apolegamy, picks out the cardan shaft that can meet horizontal tail neutral position, installs.
Described simple for the aligning crossed universal shaft modular construction of horizontal tail steering wheel is installed, to manufacture easy for installationly, reliability is high, has good maintainability.Adopt this kind of aligning cardan shaft, horizontal tail steering wheel straight line motion can be converted into and rotate the plane motion combining with straight line motion, can compensate again and manufacture the error producing in assembly process, guarantee neutral position and the control surface deflection angle of horizontal tail.
