Description
Technical Field
[0001] The utility model relates to the technical field of a zero-position calibration device for a steering propeller, in particular to a zero-position calibration device for a steering propeller. Background Art
[0002] The zero-position calibration of the prior art is an important task in the production of rudder propellers. The zero-position calibration is to make the angle between the input axis of the rudder propeller and the output axis of the rudder propeller in the top-view direction zero degree, and calibrate this position so that when the rudder propeller is installed on the ship, it can be used to identify the positive propulsion direction of the rudder propeller relative to the hull. The usual practice is to use a positioning pin. When it is in the zero position, the pin is inserted into the pre-punched zero position hole to determine whether the rudder propeller is in the zero position.
[0003] A zero-position calibration device for a rudder propeller is disclosed in the publication number CN213566426U. Although the zero-position calibration device of the utility model has the advantages of easy installation, safety and reliability, and high calibration accuracy.
[0004] However, the zero-position calibration device for the steering propeller has the following disadvantages:
[0005] (1) When it is necessary to observe whether the axis angle reaches zero, personnel are often required to observe with the naked eye, which will result in a certain deviation and affect the accuracy of the axis angle zero;
[0006] (2) When installing and fixing the zero position calibration, the operation is rather complicated and cannot be installed quickly, which affects work efficiency.
[0007] In view of this, the present utility model is proposed. Utility Model Content
