Abstract
The utility model belongs to the technical field of rocket servo mechanisms and particularly relates to a single-knuckle-bearing connecting rod rocker arm transmission mechanism for a servo mechanism. The problem of transmission connecting of a straight line output type servo mechanism and a rudderpost is solved, and space coordination between two moving bodies can be adapted. The single-knuckle-bearing connecting rod rocker arm transmission mechanism comprises an actuating rod (1), a knuckle bearing (2), a connecting rod (3), a back pin (4), a rocker arm (5), a front pin (6) and a rudderpost (7). The outer circle of the knuckle bearing (2) is arranged on the connecting rod (3), the inner circle of the knuckle bearing (2) penetrates through the front pin (6) and then is connected with the end of the actuating rod (1), the other end of the connecting rod (3) is connected with the rocker arm (5) through the back pin (4), and the rocker arm (5) is fixedly connected with the rudderpost (7).
Description
Technical field
The invention belongs to rocket servomechanism technical field, be specifically related to simple joint bearing connecting rod rocking-arm driving mechanism for a kind of servomechanism.
Background technology
To be China control the general designation of actuating unit subsystem to flights such as carrier rockets to servomechanism, comprises air rudder servomechanism, driving engine waves servomechanism, gas rudder servomechanism.And servomechanism is conventionally according to several types such as the difference Organic Electricity servomechanism of its energy, electro-hydraulic servomechanism, combustion gas hydraulic servo mechanism, air-powered servoes, no matter which type of servomechanism is finally to realize the swing of controlled object to control.
The present invention proposes a kind of transmission device of connecting rod rocking arm of simple joint bearing, the straight-line motion of realizing servomechanism actuator is converted into rotatablely moving of rudder system, the transmission device of the connecting rod rocking arm of simple joint bearing comprises connecting rod, rocking arm, oscillating bearing, connecting pin etc., the structure of employing simple joint bearing had both been guaranteed the harmony of transmission campaign, can greatly improve transmission stiffness again, when rudder system zero-bit, the design not in 90 ° of rocking arm and operating bar has greatly reduced non-linearity, improved symmetry, finally reach scantling of structure less, transmission stiffness is higher, the better target of transmission accuracy.
The present invention will be described below.
Summary of the invention
Object of the present invention, not enough for prior art, a kind of problem that is in transmission connection that solves straight line output type servomechanism and rudderpost is provided, adapt to the simple joint bearing connecting rod rocking-arm driving mechanism for a kind of servomechanism of the reconciling spatial scale problem between two movable bodies.
Technical scheme of the present invention is:
A simple joint bearing connecting rod rocking-arm driving mechanism for servomechanism, comprising: operating bar, oscillating bearing, connecting rod, rear pin, rocking arm, front pin and rudderpost; The outer ring of oscillating bearing is arranged on connecting rod, and inner ring links together with the end of operating bar through after front pin; The other end of connecting rod is connected with rocking arm by rear pin, and rocking arm and rudderpost are fixed together.
Rudderpost is in the time of 0 °, and the angle of Rocker arm 5 and operating bar is 85 °.
The invention has the beneficial effects as follows:
1. servomechanism connecting rod rocking-arm driving mechanism is generally doublejointed bearing mode, and this project is used an oscillating bearing to realize above-mentioned functions, in one end of connecting rod, an oscillating bearing is installed, and the size of connecting rod can be short as far as possible, shortens servomechanism zero-bit length;
2. in transmission device, only use an oscillating bearing, both well adapt to the motion that the space three-dimensional installation error of knowing clearly causes inharmonious, reduced again oscillating bearing quantity, improve rigidity, reduce drive gap;
3. between servomechanism and rocking arm, adopt pin to be connected, install simple and easyly, simplify interface coordination;
4. rocking arm and the operating bar very big non-linearity that reduced not in 90 ° during zero-bit, has improved symmetry.
This technical scheme is compared with existing domestic and international existing scheme, reduced oscillating bearing quantity, improved rigidity, reduced volume, optimized linearity and the symmetry of transmission, and supporting technology is more ripe, easily realizes.
Accompanying drawing explanation
Fig. 1 is simple joint bearing connecting rod rocking-arm driving structural scheme of mechanism for a kind of servomechanism.
1. operating bar, 2. oscillating bearing, 3. connecting rod, 4. rear pin, 5. rocking arm, 6. front pin, 7. rudderpost.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, a kind of servomechanism of the present invention's proposition is further introduced with simple joint bearing connecting rod rocking-arm driving mechanism:
A simple joint bearing connecting rod rocking-arm driving mechanism for servomechanism, comprising: operating bar 1, oscillating bearing 2, connecting rod 3, rear pin 4, Rocker arm 5, front pin 6 and rudderpost 7; The outer ring of oscillating bearing 2 is arranged on connecting rod 3, and inner ring links together through front pin 6 end rear and operating bar 1; The other end of connecting rod 3 is connected with Rocker arm 5 by rear pin 4, and Rocker arm 5 and rudderpost 7 are fixed together.
Rudderpost 7 is in the time of 0 °, and the angle of Rocker arm 5 and operating bar is 85 °.
Fig. 1 is the principle outside drawing of this invention, operating bar 1, connecting rod 3 link together by oscillating bearing 2 and front pin 6, operating bar 1 is made upper and lower straight-line motion in direction as shown, the outer ring of oscillating bearing 2 is arranged on connecting rod 3, inner ring links together with the end of operating bar 1 through after pin, due to the space drive characteristic of oscillating bearing 2, connecting rod 3 can adapt to the reconciling spatial scale in certain limit, has therefore just allowed the not repeatability of operating bar 1 plane of movement and Rocker arm 5 plane of movement.In the present invention, the other end of connecting rod 3 is connected with Rocker arm 5 by rear pin 4, and Rocker arm 5 and rudderpost 7 are fixed together, and the swing of Rocker arm 5 is converted into the rotation of rudderpost 7, and the motion of the swing of Rocker arm 5 by connecting rod 2 realizes.
In the present invention, when rudderpost 7 is during in 0 °, the angle of Rocker arm 5 and operating bar is 85 °, rather than traditionally 90 °, adopts after measure of the present invention, and the linear corresponding relation of the straight-line displacement of operating bar 1 and the displacement of rudderpost pendulum angle is more excellent, and transmission accuracy is higher.
The present invention uses the structure of simple joint bearing, saves the space on operating bar 1 sense of motion, adapted to the sports coordination of two bodies, and transmission stiffness is greatly improved.
When the present invention installs, only the plug of pin be need carry out, installation procedure and operation easier simplified.
The present invention is only comprised of 6 parts, and structure is small and exquisite simple, with low cost.
