Abstract
The invention relates to a torque measuring device for a leading wire of a strong-line-force small-load stabilized platform. A rotating shaft of the stabilized platform is fixed to rope disc through a coupler, the rope disc can rotate along with the rotating shaft, one end of a testing rope is fixed in a rope groove in the outer circumference of the rope disc, and the other end of the testing rope is fixed to a pull ring of a tension meter after winding through the rope groove in the outer circumference of the rope disc. The torque measuring device is simple in structure and does not need a strain gauge and a processing circuit, a connector is flexible, and assembly and disassembly are convenient.
Description
Technical field
The invention belongs to stable platform lead-in wire torque measuring device, particularly one large line strength little load stabilization platform lead-in wire torque measuring device.
Background technology
At present, typical stable platform is made up of platform framework, torque motor, angle inductor, rate gyro, control circuit and load etc., and the extraction cable majority of load etc. adopts repeatedly wears axle mode cabling to reduce its lead-in wire moment to the non-linear effects of stable platform tracking performance.When load rotating inertia is very little and load extension line cable strength is very large, cable lead moment will significantly increase the non-linear effects of stable platform tracking performance, reduce cable lead moment and first want quantitative test to go out cable lead moment.
The shortcoming of prior art
Answer: existing torque measuring device utilizes the piezoelectric effect principle of foil gauge mostly, and measured piece pastes foil gauge, measure moment by monolithic full-bridge or group bridge mode treatment circuit.Apparatus structure is complicated, and complex operation, need paste foil gauge on measured piece, and the stickup of foil gauge requires very high, inappropriate stickup will cause zero to waft and the problem such as creep, also need inspection to have bubble-free, warpage, come unstuck after strain gauge adhesion, and measure with or without short circuit, open circuit and resistance sudden change etc.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of large line strength little load stabilization platform lead-in wire torque measuring device.Its structure is simple, without the need to foil gauge and treatment circuit, and interface flexible, easy accessibility.
The present invention solves the technical scheme that its technical matters takes: the rotation axis of stable platform is fixed by shaft coupling and cheese, cheese can rotate with rotation axis, one end of the excircle grooving internal fixtion test rope of cheese, the draw ring of excircle grooving and tautness meter that the other end that test is restricted walks around cheese is fixed.
Structure of the present invention is simple, without the need to foil gauge and treatment circuit, and interface flexible, easy accessibility.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is front view of the present invention;
Fig. 2 is vertical view of the present invention.
Embodiment
As shown in Figure 1, the rotation axis 2 of stable platform 1 is fixed by shaft coupling 3 and cheese 4, cheese 4 can rotate with rotation axis 2, and one end of the excircle grooving internal fixtion test rope 6 of cheese 4, the draw ring of excircle grooving and tautness meter 7 that the other end testing rope 6 walks around cheese 4 is fixed.
Described test rope 6 is fixed by cheese briquetting 8 with cheese 4.
The leaded hole, center of described cheese 4, shaft coupling 3 and rotation axis 2, the extraction cable 5 of stable platform 1 is drawn by fairlead.
Apply pulling force until stable platform rotation axis 2 rotates to test rope 6 by tautness meter 7, read the reading of twice tautness meter, be designated as A, B respectively, and measure and cheese 4 tests rope 6 and be designated as C to the radius distance of rotation axis 2, then the lead-in wire moment of cable drawn by stable platform is (B-A) C.
