The ability of atm difference, it is ensured that the accuracy of form and position of frame assembly, reduction Overall Power Consumption.
Background technology
Control-moment gyro is that the spacecraft of the longtime runnings such as space station, remote sensing satellite, optical satellite realizes gesture stability
Crucial actuator, directly affect the pointing accuracy and degree of stability of spacecraft.From the sixties in last century, the U.S. and E Luo
Control-moment gyro product is applied successfully to the large-scale space flight such as Mir space station, skylab and international space station by this
On device.
Frame assembly structure is the important component part of control-moment gyro, for supporting high speed rotor, and to turn at a high speed
Minor structure provides sealing, the vacuum environment of cleaning.At present, control-moment gyro frame assembly mainly has two kinds of versions.One
Plant is with U.S.'s Honywell companies M50 control-moment gyros and St. Petersburg, Russia commander's instrument institute 100Nms controls
Moment gyro is representative, and frame assembly is designed to three stage structure, including frame spoke and architrave, supports high speed rotor by frame spoke,
After having the disadvantage that high speed rotor loads frame assembly, it is impossible to realize that assembly precision detection and Precision Balancing are tested.Another kind is with state
The large-scale control-moment gyro in border space station is representative, and frame assembly includes integral frame and seal closure, by integral frame
Supporting high speed rotor.Both frame assembly structures have the shortcomings that common：When frame assembly bears inside and outside atm difference, frame
The stress deformation of frame component can change the stress state of high-speed bearing, affect Overall Power Consumption, the level of vibration of control-moment gyro
And working life.
Therefore, design novel frame modular construction and there is weight to control-moment gyro reducing power consumption, vibration and noise reducing and long-life
The meaning wanted.
The content of the invention
Present invention solves the technical problem that being：Overcome the deficiencies in the prior art, design a kind of Novel control moment gyro frame
Frame modular construction, effectively improves the ability that frame assembly resists atm difference, and in eliminating welding process, instantaneous high heat is at a high speed
The impact of shafting.
The technical scheme is that：A kind of Novel control moment gyro frame assembly structure, including seal closure, frame width,
Seal closure cushion block, architrave and external screw thread taper bolt；
The seal closure is arc thin walled shell；Frame width is eight claw supporting structures, and frame width centre position is a through hole, is used for
Support high speed rotor；External screw thread taper bolt one end is circular cone, and the other end is external thread structure；8 mounting ears are arranged at frame width bottom, often
There is 1 through hole on individual mounting ear, on each two mounting ear, have a taper hole, through hole is used for installing clamp-screw, and taper hole is used for pacifying
Dress external screw thread taper bolt；Solid slug of the described seal closure cushion block for rectangular shape；Described architrave is cylindrical shell, is coated
In the centre position of seal closure, the sealing system of inner vacuum is constituted with seal closure；Frame width is 2, uses external screw thread circular cone respectively
Then finger setting is fastened at frame width on the upper and lower both sides inside architrave with screw on the upper and lower both sides inside architrave, high
After fast rotor is assembled to frame assembly structure, is positioned and supported by the frame width on the upper and lower both sides of architrave；Seal closure cushion block
With screws tighten in the upper and lower ends of architrave, for location sealing housing.
The quantity of external screw thread taper bolt is 8, and the quantity of seal closure cushion block is 16.
The axis hole centrage of frame width is not less than 200mm with the distance of seal weld junction.
Compared with the prior art, the invention has the advantages that：
(1) effect of conventional frame modular construction frame width is supporting high speed rotor and composition sealing system, and frame width is subject to big
Draught head deformation directly results in high-speed bearing loading and changes, and affects high speed rotor working condition, and it is new that this patent is proposed
Frame assembly structure, using bearing member and the detached structure of sealing member, is made up of sealing system to undertake frame seal closure and architrave
The atm difference of frame component, frame width supporting high speed rotor, is not affected by atm difference, can guarantee that the accurate of high-speed bearing adds
Carry, reduce Overall Power Consumption.
(2) the novel frame modular construction of this patent, constitutes sealing system by seal closure and architrave, and in high speed rotor
High speed shafting is supported by frame width, and, away from seal closure solder side, in eliminating welding process, instantaneous high heat is at a high speed for high speed shafting
The impact of shafting and lubricating oil.
(3), after high speed rotor loads frame assembly, before seal closure sealing welding, the loss of weight between frame width bearing claw can be passed through
Hole carries out assembly precision detection and Precision Balancing is tested.State after high speed rotor loading frame assembly is with high speed rotor most
Whole working condition is identical, therefore carries out rotor dynamic balancing in this condition, can reach high-grade dynamic balance accuracy, effectively can drop
The micro-vibration level of low high speed rotor.
