Air steering engine rudder piece angle and electrical angle overlapping zeroing execution mechanism

Abstract

The invention discloses an air steering engine rudder piece angle and electrical angle overlapping zeroing execution mechanism. When zeroing is carried out, a rudder piece begins to be in oscillating motion under an acting force, the rudder piece drives a fixed shaft to be in synchronous oscillating motion through a shift fork, a rolling bearing II rolls up and down in a waist-shape groove to force an oscillating bar to oscillate, the oscillating bar drives a rotation shaft to rotate, and meanwhile, drives an angle sensor I to rotate synchronously through an elastic coupler, and thus the angle of the rudder piece is collected. When the oscillating bar stops oscillating, the rudder piece is in the zero position; and at the moment, if error appears between the zero position angle collected by the angle sensor I and the angle of an angle sensor II, a pressing plate II and a screw II on the steering engine are loosened, the angle sensor II is rotated to enable the angle sensor II to be overlapped with the zero position angle of the angle sensor I, and a screw II on the steering engine is then fastened. The execution mechanism is simple in structure, low in cost and convenient to assemble, maintain and debug, and meets the requirement that the overlap degree of the electrically-controlled angle of the steering engine and the mechanical angle of the rudder piece is guaranteed to be in graded precision.

Description

technical field [0001] The invention belongs to the technical field of measurement and control, and more specifically relates to a zero-adjusting executive mechanism for coincidence of rudder plate angle and electrical angle of an air steering gear. Background technique [0002] At present, when the air steering gear is assembled and debugged, the angle sensor of the air steering gear should coincide with the mechanical zero position of the rudder plate on the output shaft of the steering gear and the electrical zero position of the angle sensor, and the method of directly reading the scale angle protractor plus a pointer is adopted. When the angular accuracy of the degree of coincidence between the mechanical zero position of the rudder blade angle and the electrical zero position of the steering gear angle sensor is required to be graded, the above method cannot meet the requirements for the graded angle accuracy. Contents of the invention [0003] In view of the above d...
