TH149140B - Blade angle measuring tool - Google Patents

Abstract

The propeller angle gauge is fabricated. Used as a tool for setting the angle of torque of the impeller in Piston engine And can also set the torque angle of the propeller to be the same in all blades of the propeller There is a working principle with a set of angle measurements (1) connected to the contact of the impeller hub. To be vertical with the blade angle measuring tool User can twist Adjust the angle with the shaft torsion angle of the propeller (3) to set the torsion angle on the blade. In the manner of attaching the shaft axis Measure the torsional angle of the impeller to the propeller. When the propeller has the desired degree The shaft torsion angle of the impeller is attached to the propeller to have Light emanating The user can set the propeller torsion angle from the propeller torsion angle indicator (4) and the propeller torsion angle gauge (2). Tighten the fixing axis (5) to fix the shaft torsion angle of the impeller that can be rotated and rotated. And then turn it around to set the angle of the propeller to another propeller

Claims (1)

1.Mechanism of the propeller angle gauge The principle of operation is that the angle measuring unit base (1) is connected to the axle to measure the torsion angle of the impeller (3). To the contact of the hub of the impeller When the user wants to adjust the torsion angle of the propeller, the angle of the propeller can be adjusted by adjusting the angle of the shaft to measure the torsional angle of the impeller so that the propeller There is a desired torque angle and no light emanating between the impeller torsion shaft axis and the impeller contact, where the user can set the torsion angle from the impeller.
