Embodiment Construction

[0016] The present invention adds "fast" and "slow" adjustment functions to the steering gear. The steering gear speed selection switch S1 is designed. When the steering gear is close to the expected position during the adjustment process, the slow speed adjustment can be selected to increase the adjustment accuracy and improve work efficiency.

[0017] The present invention adds the adjustment functions of "fine adjustment" and "coarse adjustment" to the steering gear. Select a DC voltmeter M1 with a range of -15V to +15V to indicate the feedback voltage value of the servo position, and design a voltage divider circuit so that the feedback voltage value is divided and indicated by the digital display indicator M2. Adopting this voltage division method can more accurately reflect the variation of the feedback voltage value of the steering gear during the adjustment process of the steering gear, realize the coarse adjustment and fine adjustment of the steering gear position, an...

Abstract

The invention belongs to the technical field of helicopter test, and especially relates to a steering engine tester. The series steering engine tester is composed of a power supply circuit, a steering engine position adjustment circuit and a feedback voltage display circuit. The power supply circuit adopts standard 220VAC input, outputs direct-current power after internal conversion, provides working power for the steering engine position adjustment circuit and the feedback voltage display circuit, and provides working power for a to-be-tested series steering engine component. The steering engine position adjustment circuit is used for controlling extension and retraction movement of an output shaft of a series steering engine and adjusting a steering engine installation position. The feedback voltage display circuit is used for monitoring a position feedback voltage value of the serial steering engine in real time during steering engine position adjustment. Continuous position correction on a series steering engine can be effectively realized, and the neutral point and the extension and retraction limit installation positions of the series steering engine can be precisely positioned.

Description

technical field [0001] The invention belongs to the technical field of helicopter testing, in particular to a steering gear tester. Background technique [0002] The tandem steering gear is a continuous working electromechanical device. The output shaft of the tandem steering gear moves linearly in the direction of extension and retraction, and the full stroke is transmitted to the load of the movable part within the limit range. There is a DC electric motor inside the tandem steering gear, which can realize rotation in two directions through the conversion of the power supply polarity, and drive the output shaft to extend and retract; its internal stroke limiter controls the limit stop position of the output shaft of the steering gear; Feedback potentiometer The output shaft position feedback component will give the feedback electrical signal of the output shaft position. [0003] The series steering gear and the parallel steering gear together constitute the actuator of t...
