Problems solved by technology
[0003] Most domestic launch vehicle position sensors adopt redundant technology, such as the integrated dual / triple redundant position sensor used on active launch vehicles. It is difficult for this kind of integrated redundant position sensor to meet the miniaturization requirements of the volume
Due to low reliability requirements, the domestic tactical model electric servo mechanism position sensor does not use redundant technology

The invention discloses an electric servo mechanism and a debugging method thereof, which are designed according to the characteristics that a launcher type small-sized servo mechanism is relatively high in requirements on sensitivity of volume and weight as well as feedback reliability. A pair of feedback amplifying devices is arranged at the two sides of an output shaft, each feedback amplifying device comprises a potentiometer, a primary gear, a secondary gear, and the like, wherein the potentiometer adopts a conductive plastic potentiometer, so that the weight and the volume of the electric servo mechanism are greatly reduced; the primary gear and the secondary gear adopt staggered-tooth fit, so that a gap can be eliminated. The debugging method for the electric servo mechanism provided by the invention is a debugging method for the electric servo mechanism based on a dual-position feedback device. By virtue of a mode of testing and screening before mounting the potentiometer, mounting the gear amplifying devices and eliminating the gap in a staggered-tooth mode, the position feedback detecting precision is improved, and the two-path feedback output consistency is guaranteed.
Description
technical field [0001] The invention relates to a debugging method of an electric servo mechanism based on a dual-position feedback device, in particular to an electric servo mechanism and a debugging method thereof. Background technique [0002] The position servo system compares the position feedback signal with the command signal, and then follows the command for action, so as to obtain accurate position, speed and power output. As an important actuator of the launch vehicle, the servo system realizes position tracking by collecting position feedback signals in real time, and drives the rocket engine to swing in both directions. As an important component of the servo system, the position sensor is very important for its reliability. [0003] Most domestic launch vehicle position sensors adopt redundant technology, such as the integrated dual / triple redundant position sensor used on active launch vehicles. It is difficult for this kind of integrated redundant position sen...
