Design is to realize.Cartesian coordinate system O-XYZ used by curve surface of raceway as shown in Figure 3 generates.It, can be better by the figure
Understand the generation of antarafacial angular contact roller bearing special surface and the practical significance of parameters.
The typical case environment of the two-way ball-screw anti-reverse-rotation device designed according to the present invention is as shown in Figure 4.Level peace
Determining face 1 can swing up and down around a transverse horizontal axis 2, to realize trim aircraft awing, such as carry according on aircraft
The distribution of load adjusts aspect, to keep the stationarity of flight.In the tail inner side of airframe 8, upper cardan and
Ball nut 3 is connected to a vertical ball-screw 601, and ball-screw 601 is driven by a driving device 5, can be to two
A direction rotates.The aerodynamic loading acted on horizontal stabilizer 1 is transmitted to ball-screw by upper cardan and ball nut 3
On 601.The vertical component that this aerodynamic loading acts on ball-screw may be the downward pressure in direction, it is also possible to direction
Upward pulling force.Since the ball-screw being connected with ball nut is there are lead (thread), the torque in some direction also can be simultaneously
It acts on ball-screw 601.
Torque component to prevent aerodynamic loading from generating drives ball-screw to be freely rotatable, and has used of the present invention
Two-way anti-reverse-rotation device 6, device are mounted on airframe 8 by a lower cardan 7.Anti-reverse-rotation device loses in order to prevent
Effect, can provide the two-stage brake 4 of a routine again to ensure safety.Generally speaking, in the torque component of aerodynamic loading
On the direction for promoting horizontal stabilizer driving, anti-reverse-rotation device provides a biggish brake force；In the torque of aerodynamic loading
Component hinders on the direction of horizontal stabilizer driving, and the brake force that anti-reverse-rotation device provides is smaller.
In addition, no matter the torque component of aerodynamic loading is the driving for promoting or hindering ball-screw, in order to guarantee to drive
The most effective work of unit 5, driving moment needed for driving ball-screw to both direction should be roughly equal.For example, in Fig. 5
In, arrow 9 indicates the direction of motion expected from ball nut 3, and arrow 10 indicates the aerodynamic loading acted on horizontal stabilizer 1,
Arrow 11 indicates that the aerodynamic loading acted on horizontal stabilizer 1 is transmitted to the axial load on ball-screw, and arrow 12 indicates
The aerodynamic loading torque component being transmitted on ball-screw 601, if the torque component 12 uses TLOADIndicate, then to TLOAD
Simulation torque T needed for opposite direction (i.e. the direction of mobile ball nut shown in arrow 9) driving ball-screwMIN(figure
Middle label 13) it is equal to aerodynamic loading torque component TLOADIn addition the moment of resistance T applied by bearingBRAKE(figure label 14), i.e.,：
TMIN=TLOAD+TBRAKE (small)
At this point, antarafacial angular contact roller bearing provides lesser moment of resistance TBRAKE (small)。
Referring to Fig. 6, arrow 11 represents same aerodynamic loading vertical component, therefore aerodynamic loading torque component TLOAD(figure
Middle label 12) also do not change, arrow 9 indicates the direction of motion expected from ball nut, and 14 indicate the moment of resistance T that bearing appliesBRAKE,
T at this timeMIN(figure label 13) on the direction that aerodynamic loading torque component promotes ball-screw driving, i.e., and TLOADDirection
When identical, relational expression is as follows：
TMIN=-TLOAD+TBRAKE (big)
At this point, antarafacial angular contact roller bearing provides biggish moment of resistance TBRAKE (big)。
In order to keep driving moment needed for driving ball-screw toward both direction roughly equal, i.e., in above-mentioned two relational expression
TMINIt is equal in magnitude, it is necessary to meet：
TLOAD+TBRAKE (small)=-TLOAD+TBRAKE (big)
It can be concluded that
TBRAKE (big)-TBRAKE (small)=2TLOAD
From the above equation, we can see that as the larger moment of resistance T of antarafacial angular contact roller bearing offerBRAKE (big)And the difference of smaller resistance square
TBRAKE (small)About aerodynamic loading torque component TLOADTwice when, drive ball screw turns required for driving moment TMIN
It is roughly equal.
In addition, the moment of resistance that anti-reverse-rotation device provides is a function for acting on ball-screw upper pulling force or pressure.Cause
This, there is the relationship of an approximately linear, on the direction that aerodynamic loading torque component hinders ball-screw driving, anti-reverse-rotation device
The lesser moment of resistance is provided, but on the direction that aerodynamic loading torque component promotes ball-screw driving, anti-reverse-rotation device is provided
The biggish moment of resistance, and the moment of resistance is with TLOADIncrease and increase.
From other aspect, the aerodynamic loading axial component that no matter ball-screw is subject to is pressure or pulling force, driving
When ball-screw rotates, driving device mainly needs to overcome on the direction that aerodynamic loading torque component hinders ball-screw driving
The drag torque T that aerodynamic loading generatesLOAD；It is pneumatic to carry on the direction that aerodynamic loading torque component promotes ball-screw driving
Lotus torque component TLOADThe larger moment of resistance that offer power-assisted but driving device need that antarafacial angular contact roller bearing is overcome to provide, in this way
Regardless of which direction to drive ball-screw to, the driving moment that driving device needs to export is roughly the same.
Regardless of the axial load direction acted on the ball-screw 601, has and only one antarafacial is tilting
Roller bearing is in action.Under the action of pressure loading, the interior shaft shoulder 602 drives first bearing inner ring 609 to first end
605 direction of lid is mobile, the roller on the first retainer 613 is pressed on first bearing outer ring 611, at this time first end cover 605
The bearing working of side.Due to the special roller path structure of antarafacial angular contact roller bearing, institute is hindered in the torque component 12 of aerodynamic loading
On the direction for stating the driving of ball-screw 601, the driving of the ball-screw 601 is by the lesser moment of resistance of bearing, but pneumatic
On the direction that the torque component 12 of load promotes the ball-screw 601 to drive, the driving of the ball-screw 601 just needs gram
The larger moment of resistance of bearing offer is provided.When drag load acts on the ball-screw 601, situation is similar；In this feelings
Under condition, the interior shaft shoulder 602 drives second bearing inner ring 610 mobile to 606 direction of second end cover, will be 614 on the second retainer
Roller be pressed on second bearing outer ring 612, the bearing working of 606 side of second end cover at this time.
