Repair is unloaded to replace.
Driving gear, driven gear and angle transducer described above is two groups；Two driving gears are separately mounted to spiral shell
On the blade root for revolving two blades of paddle, driven gear and angle transducer are fixed on propeller paddle shell by bearing and driving gear
Corresponding position；The signal of two angle transducers output is all transferred to processor by end face conducting ring and end face brush box.This
Sample, when one group of driving gear, driven gear and angle transducer work, another group can be spare, once one group of work is asked
Topic, another group alternatively works, functional reliability higher.
The driving gear of the present invention is coaxially fixed on the blade root of blade, is rotated with propeller, with driven gear phase
To static；Only blade angle when, driving gear drives driven gear rotation, angle transducer to acquire driven tooth with blade angle
The rotation number of teeth signal of wheel, and rotational angle is calculated, it is transferred to end face conducting ring, then processing is transmitted to by end face brush box
Device, received signal processing is blade angle by processor, and is stored and exported and shown to display screen.The information of storage can
The use that makes a search is gone to be taken out from processor at any time.The present invention can measure and timely feedback blade angle at any time, simple in structure,
Reliably, easy for assemble or unload, blade angle measurement is accurate, can realize that field maintenance is replaced, maintenance replacement cost is low.
