Background technique
Control-moment gyro is that the long-term running spacecraft such as space station, remote sensing satellite, optical satellite realizes gesture stability
Crucial executing agency, directly affect the pointing accuracy and stability of spacecraft.Since 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 of control-moment gyro, is used to support high speed rotor, and turn for high speed
Minor structure provides sealing, clean vacuum environment.Currently, there are mainly two types of structure types for control-moment gyro frame assembly.One
Kind is with Honywell company, U.S. M50 control-moment gyro and St. Petersburg, Russia commander's instrument research institute 100Nms control
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,
The disadvantage is that cannot achieve assembly precision detection and Precision Balancing test after high speed rotor is packed into frame assembly.Another kind is with state
Border space station is representative with large-scale control-moment gyro, and frame assembly includes integral frame and seal closure, by integral frame
Support 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, influence Overall Power Consumption, the level of vibration of control-moment gyro
And working life.
Therefore, design novel frame modular construction has weight to control-moment gyro reducing power consumption, vibration and noise reducing and long-life
The meaning wanted.
Summary of the invention
Technical problem solved by the present invention is overcome the deficiencies in the prior art, designs a kind of Novel control moment gyro frame
Frame modular construction effectively improves the ability that frame assembly resists atm difference, and instantaneous high heat is to high speed in elimination welding process
The influence 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 middle 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 a mounting ear, there is a taper hole on every two mounting ear, through-hole is used to install clamp-screw, and taper hole is used to pacify
Fill external screw thread taper bolt；The seal closure cushion block is the solid slug of rectangular shape；The architrave is cylindrical shell, cladding
Sealing system in the middle position of seal closure, with seal closure composition inner vacuum；Frame width is 2, uses external screw thread circular cone respectively
Then frame width is fastened on the upper and lower both sides inside architrave by finger setting on the upper and lower both sides inside the architrave with screw, 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, it to be used 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 center line of frame width is not less than 200mm at a distance from sealing welding junction.
Compared with the prior art, the invention has the advantages that:
(1) effect of conventional frame modular construction frame width is bearing high speed rotor and composition sealing system, and frame width is by big
Draught head deformation directly results in high-speed bearing load and changes, and influences high speed rotor working condition, and this patent proposes novel
Frame assembly structure, the structure separated using bearing member and sealing element, forms sealing system by seal closure and architrave to undertake frame
The atm difference of frame component, frame width support high speed rotor, are not influenced by atm difference, can guarantee that the accurate of high-speed bearing adds
It carries, reduce Overall Power Consumption.
(2) the novel frame modular construction of this patent forms sealing system by seal closure and architrave, and in high speed rotor
High speed shafting is supported by frame width, and high speed shafting can eliminate in welding process instantaneous high heat to high speed far from seal closure welding surface
The influence of shafting and lubricating oil.
(3) high speed rotor be packed into frame assembly after, 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 test.State and high speed rotor after high speed rotor loading frame assembly are most
Whole working condition is identical, therefore carries out rotor dynamic balancing in this state, can reach high-grade dynamic balance accuracy, can effectively drop
The micro-vibration of low high speed rotor is horizontal.
