Problems solved by technology

The structure of the device is complex and the operation is cumbersome. It is necessary to paste the strain gauge on the measured piece, and the sticking of the strain gauge is very demanding. Improper sticking will cause problems such as zero drift and creep. After the strain gauge is pasted, it is necessary to check whether there are air bubbles. , warpage, degumming, and measure whether there are short circuits, open circuits, and sudden changes in resistance, etc.

Embodiment Construction

[0011] Such as figure 1 As shown, the rotating shaft 2 of the stable platform 1 is fixed with the rope reel 4 through the coupling 3, and the rope reel 4 can rotate with the rotating shaft 2, and one end of the test rope 6 is fixed in the outer circumference rope groove of the rope reel 4, and the test rope 6 The other end walks around the outer circumferential rope groove of the rope reel 4 and fixes with the pull ring of the tension gauge 7.

[0012] The test rope 6 and the rope reel 4 are fixed by the rope reel pressing block 8 .

[0013] The centers of the rope reel 4, the shaft coupling 3 and the rotating shaft 2 have lead holes through which the lead cables 5 of the stable platform 1 are drawn.

[0014] Apply tension to the test rope 6 through the tension meter 7 until the rotating shaft 2 of the stable platform rotates, read the readings of the tension meter twice, and record them as A and B respectively, and measure the radial distance from the test rope 6 on the rope...

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 [0001] The invention belongs to a lead moment measuring device for a stable platform, in particular to a lead moment measuring device for a stable platform with large wire strength and small load. Background technique [0002] At present, a typical stable platform is composed of a platform frame, torque motor, angle sensor, rate gyroscope, control circuit and load, etc. Most of the lead-out cables of the load are routed through the shaft multiple times to reduce the lead torque of the load. Nonlinear effects on platform tracking performance. When the moment of inertia of the load is small and the force of the cable leading out from the load is large, the nonlinear influence of the cable lead moment on the tracking performance of the stable platform will increase significantly. To reduce the cable lead moment, the first step is to quantitatively test the cable lead moment . [0003] Disadvantages of existing technology [0004] Answer: Most of the existing ...
