Seat is supportted, two support bases are separately positioned on the front and rear sides of propeller hub component, supporting guide, propeller hub are provided on each support base
The support shaft of component front and rear sides is ridden over respectively on two supporting guides；The indicating mechanism includes dial and pointer, scale
Disk and pointer are arranged on the end face of support shaft, and dial is rotated with support shaft, and the direction of pointer remains unchanged.
Preferably, long arc-shaped holes are provided on the dial, dial is matched by the end face of long arc-shaped holes and support shaft
It closes.
Preferably, the pointer is arranged on the end face of support shaft by bearing, and bearing is located at the center of dial, scale
The center of disk is additionally provided with the avoid holes of evacuation bearing.
Preferably, V-shaped groove is provided at the top of the support base, supporting guide is cylindrical-shaped structure, and supporting guide is fixed
It is arranged on the V-shaped groove of support base.
Due to the application of the above technical scheme, the utility model has the advantage that compared with prior art
The tuning for Controllable Pitch Propeller static balance extension of the utility model, which retries, tests drift angle indicating mechanism, a set of in support axial end installation
Indicating mechanism makes tuning for Controllable Pitch Propeller during progress static balance extension is retried and tested, directly can read α's by pointer and dial
Specific value improves test efficiency, and the accuracy of guarantee test result.
Detailed description of the invention
