Technical field
The utility model is related to used in space shuttle horizontal tail, can be realized for aircraft stabilizer torque tube compensation elevator and swing fortune
Dynamic bearing, is specifically related to a kind of Self-aligning both sides band block wing needle roller combination bearing.
Background technology
Aircraft horizontal tail is very important part for controlling the pitching of aircraft, and horizontal tail has two effects, with gentle adjustment
Full machine focus, the wing focus of general aircraft before center of gravity, but Center of Pressure after center of gravity so horizontal tail is to provide negative lift,
Do not worked as horizontal tail breaks down, aircraft will bow, and can not fly.With speed, power, prestowage change, pitching balance
It can not stop to change, it is also desirable to the control of horizontal tail.
From the point of view of domestic air mail development situation, the development and large-scale production of aircraft self-contained bearing are imperative.Therefore, it is possible to
To develop flight control system bearing, the effect such as carrying, pitching, transmission is played, the realization to each systemic-function is played to pass
Important effect, it is indispensable.
The content of the invention
In order to make up above-mentioned technological deficiency, solve technical problem, the utility model provides a kind of Self-aligning both sides
Band block wing needle roller combination bearing, the combination designed by Internal and external cycle special construction meets the performance of flight control system bearing, energy
The fault rate of enough effectively control aircraft horizontal tails in operation.
To achieve these goals, the technical scheme that the utility model is used is：A kind of Self-aligning both sides band block wing is rolled
Pin combination bearing, including aligning outer ring, inner ring, needle roller, self-aligning seat washer, the flank back-up ring for being arranged on inner ring both sides；The aligning
Symmetrical two dovetail grooves in seat ring side, it is ensured that aligning outer ring loads not scratch surface；Aligning outer ring external diameter surface and aligning
Race interior surface is contacted, and needle roller is completely loaded between aligning outer ring and inner ring；Inner ring both sides are provided with flank back-up ring, a whole set of bearing of control
Amplitude of fluctuation, and limit the play space of needle roller；Aligning outer ring external diameter center is provided with oil groove.
Described aligning outer ring, inner ring and self-aligning seat washer is overall lasso；
Described aligning outer ring external diameter surface and self-aligning seat washer inner surface are spherical friction surface；
Described inner ring two ends are designed to V-groove structure；
Copper backing is additionally provided between described V-groove and flank back-up ring, check ring, V-type are provided with one end of copper backing
Groove is fastenedly connected by copper backing with flank back-up ring；
Described V-groove is 72；
Described V-groove angle is identical with the angle of flank back-up ring.
Slope of the described flank back-up ring close to the side design and horizontal direction 20 of bearing face.
The utility model beneficial effect is：The combination of Internal and external cycle special construction design, being capable of automatic aligning；Inner ring block wing
Design, the amplitude of fluctuation and the accuracy of swing angle of a whole set of bearing of control, and limit the play space of needle roller；Overall lasso knot
Structure, improves bearing rigidity and running accuracy；The dovetail groove design of self-aligning seat washer, it is ensured that outer ring, which easily loads, does not scratch friction table
Face；Light-weight design makes bearing arrangement realize high-mechanic, long-life.
