The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
The present invention adopts a cover mechanism that steering wheel and air rudder are connected and fixed, and the straight-line motion of steering wheel piston rod drives the rotation of air rudder.This mechanism is comprised of 5 kinds of parts and a kind of gauge member forms.Part is respectively rudderpost, rocking arm, connecting rod, pivot pin and 2 bearing pins, totally 6 parts, and gauge member is bearing.The structure composition of this high precision rudder transmission device sees figures.1.and.2, and respectively their relation and effect is described by function.
Rudderpost is the body element of rudder transmission device, and an end adopts the ears fork configuration, is connected with air rudder, and an end is cylindrical, is arranged on aircraft.The auricle that rudderpost is connected with air rudder has screw mounting hole, and for keeping the aerodynamic configuration of aircraft, a side is the countersunk head pin-and-hole, and opposite side corresponds to tapped through hole.Cylindrical section at rudderpost has a pin-and-hole perpendicular to its axis, is used for installing pivot pin.
The rocking arm main body is annulus, and a protruding journal stirrup has a pin-and-hole to run through perpendicular to the annulus axis.Rocking arm annulus part coordinates with the cylindrical section of rudderpost, and the pin-and-hole diameter is identical with the pin-and-hole diameter of rudderpost cylindrical section, is convenient to pivot pin and passes.Be designed with a pin-and-hole on journal stirrup, be connected with connecting rod.
The connecting rod profile is " work " font, bilateral symmetry, and respectively there is a pin-and-hole at upper shape face two ends, and corresponding position, lower shape face two ends is tapped bore.The connecting rod two ends are connected with the steering wheel piston rod with rocking arm respectively.
Pivot pin is the socket cap pin, and rudderpost and rocking arm are linked together.Bearing pin is the screw pin structure, is arranged on the two ends of connecting rod, respectively connecting rocker arm and steering wheel piston rod.
Bearing carrier ring is connected on rudderpost, is arranged on aircraft together with rudderpost, guarantees that rudderpost can rotate around its axis.
The mounting means of this rudder transmission device is: the first step is connected on bearing carrier ring on rudderpost, and rocking arm and connecting rod are coupled together by bearing pin.Second step is the rocker-arm link assembly to be put into the installed position in aircraft cabin, then with the rudderpost bearing assembly from installing inwards out of my cabin, during installation, the rudderpost cylindrical section passes rocking arm inner hole.The 3rd step was that the pin-and-hole on rocking arm is alignd with pin-and-hole on the rudderpost cylindrical section, passed with pivot pin, and rocking arm and rudderpost are connected and fixed.The 4th step was that steering wheel piston rod and connecting rod are connected and fixed by bearing pin.The 5th step was arranged on air rudder on rudderpost by screw.Whole mechanism is for being rigidly connected, guarantee the steering wheel piston rod in arbitrary displacement situation all to well-determined air rudder corner should be arranged.
Embodiment is with reference to Fig. 3 and Fig. 4.Take certain aircraft as example, require air rudder its ± operating range of 30 ° in maximum error be no more than 0.3 °.Analyze as calculated, the rudderpost of design adopts the semicircle auricle of R60mm, and 6 groups of diameters of the above's processing are the hole that φ 8mm installs air rudder, and the cylindrical section diameter is φ 40mm, and the pin-and-hole diameter on rudderpost is φ 10.Rocking arm annulus opening diameter is φ 40mm, and the pin-and-hole diameter on journal stirrup is φ 8mm, and the pin-and-hole center is 52mm to circle ring center's distance.Connecting rod two ends pin-and-hole width between centers is 40mm, and diameter is φ 8mm, and corresponding tapped bore is M8.The pin section diameter of the screw of bearing pin and installation air rudder is φ 8, and screw thread is M8.Pivot pin length is 55mm, and pin section diameter is φ 10, also is designed with the through hole of φ 1.5mm at its end, is used for the erection insurance device.Bearing adopts the standard rolling bearing of φ 40mm.Whole mechanism calculates through strength and stiffness and checks, and satisfies operating needs.
First rocking arm and connecting rod are coupled together by bearing pin during installation, then bearing carrier ring is installed the rudderpost bearing assembly by the mounting hole on the body of cabin from outside to inside at rudderpost cylindrical section top, and its cylindrical section passes the annulus on the rocking arm that places in advance in the body of cabin.After rudderpost and bearing are in place, mobile rocking arm on the rudderpost cylindrical section makes on pin-and-hole and the rudderpost on the rocking arm annulus pin-and-hole on cylindrical section corresponding, passes pin-and-hole with pivot pin rocking arm is connected with rudderpost, and adopt the insurance measure at the pivot pin end, prevent that in working process, pivot pin is deviate from.Next with bearing pin, steering wheel piston rod and connecting rod are coupled together, and steering wheel is fixed on the body of cabin, at last air rudder is arranged on rudderpost by screw, the installation of whole mechanism.
