Background technology
The variable pitch contro l device of screw propeller is under the various duties of engine and aircraft, controls screw propeller and can work under the state of the blade angle of the best, to reach the optimum working efficiency of screw propeller.Because the flight environment of vehicle of aircraft is very complicated, the variable pitch contro l device of research screw propeller, it is made to control blade angle more accurately, the best output efficiency reaching screw propeller is immutable problem, so, to the enforcement monitoring of the propeller blade angle of work, timely collection blade angle, so that research blade angle and revolution speed of propeller, engine capacity relation, and then the variable pitch contro l device studying a kind of better screw propeller necessitates, but current screw propeller all cannot be measured in real time and feed back the angle of its blade in time.
Summary of the invention
Object of the present invention solves the above-mentioned problems in the prior art exactly, and provide one to measure at any time and feed back blade angle in time, blade measurement of angle is accurate, can realize the enforcement monitoring device of the propeller blade angle that on-site maintenance is changed.
For achieving the above object, technical solution of the present invention is: a kind of enforcement monitoring device of propeller blade angle, and it comprises driving gear, follower gear, bearing, angle transducer, end face conducting ring, end face brush box, end face brush box support, processor and display screen; Driving gear is coaxially fixed on the blade root of blade; Bearing is fixed on the sidewall of screw propeller oar shell, and angle transducer is fixed on bearing, and follower gear is fixed on the axle of angle transducer, and follower gear engages with driving gear; End face brush box is fixed on motor body by end face brush box support, and end face conducting ring is fixed on the sidewall of oar shell, and the carbon brush on end face brush box is pressed on end face conducting ring; The information output of angle transducer is fixed on end face conducting ring by wire, and end face brush box is connected to the signal input part of the processor in pilothouse by wire, and the signal output part of processor connects display screen.Angle transducer gathers the rotation number of teeth signal of follower gear, and calculates rotational angle, and be transferred to processor, the signal transacting of reception is blade angle by processor, and carries out storing and export to display screen display.
Driving gear described above is made up of the two halves that can be combined into a full circle, and two halves is clamped on the blade root of blade, is fixed together by screw bolt and nut; Only some circumferentially has tooth to driving gear, when the tooth on this part-circular periphery can ensure blade angle maximum magnitude, engages all the time with the tooth on follower gear.This kind of fixed sturcture is easily installed fixing, and detachable maintaining is changed.
Driving gear described above, follower gear and angle transducer are two groups; Two driving gears are arranged on the blade root of the blade of two of screw propeller respectively, and follower gear and angle transducer are fixed on the position corresponding with driving gear of screw propeller oar shell by bearing; The signal of two angle transducer outputs is all transferred to processor by end face conducting ring and end face brush box.Like this, when one group of driving gear, follower gear and angle transducer work, another group can be for subsequent use, once one group of work goes wrong, another organizes replaceable work, and functional reliability is higher.
Driving gear of the present invention is coaxially fixed on the blade root of blade, rotates with screw propeller, with follower gear geo-stationary; When only having blade angle, driving gear is with blade angle, drive follower gear rotates, angle transducer gathers the rotation number of teeth signal of follower gear, and calculate rotational angle, be transferred to end face conducting ring, then transfer to processor by end face brush box, the signal transacting of reception is blade angle by processor, and carries out storing and export to display screen display.The information stored can be taken out from processor at any time and be done research use.The present invention can measure at any time and feed back blade angle in time, and structure is simple, and reliably, easy installation and removal, blade measurement of angle is accurate, and can realize on-site maintenance and change, maintain and replace cost is low.
