Problems solved by technology

The power-off zero-adjustment method includes the voltage balance method and the resistance balance method. In the voltage balance method, the potentiometer of the steering gear needs to be powered. Compared with the power-on zero-adjustment method, the entire operation process has been greatly simplified, but the measured physical quantity It is the converted voltage value instead of directly measuring the resistance change of the potentiometer, which is easy to introduce external interference

Abstract

The invention discloses a method for quickly zeroing an electric steering gear. The method comprises the steps that the steering gear is connected with a first tester and a second tester through connecting lines separately; one end of an output shaft is connected with the steering gear and fixed through bolts; a fixing device is placed on a special platform, the other end of the output shaft is placed in jaws of the fixing device, the output shaft is clamped through rotating bolts of the fixing device, and a current state is determined as a mechanical zero position of the steering gear; the first tester and the second tester are adjusted to ohm ranges respectively, and display values of the first tester and second tester are observed and recorded; when it is determined that the display values of the first tester and second tester are equal, it is determined that an electrical zero position coincides with the mechanical zero position, and zeroing ends. The method for quickly zeroing theelectric steering gear has the advantages that the operation is simple, the zeroing precision is high, digital display can be achieved, and the zeroing efficiency of the steering gear is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of electric servo, and in particular relates to a method for quickly zeroing an electric steering gear. Background technique [0002] As a servo actuator, the electric steering gear is more and more widely used in unmanned aerial vehicles, guided bombs and spacecraft. The fast zeroing method of the electric steering gear is a practical method to realize high-precision and fast zeroing of the steering gear. [0003] At present, the commonly used steering gear zeroing methods include power-on zero-adjustment and power-off zero-adjustment of the steering gear. The zero-adjustment device required in the power-on zero-adjustment method includes auxiliary equipment such as level blocks and feeler gauges. During debugging, the steering gear needs to be powered on to make the product work. The process is complicated and there is a risk of steering gear deviation. The zeroing process takes a long time and is risky, ...
