Abstract

The invention discloses a propulsion module zero calibration method. The propulsion module zero calibration method comprises the following steps that step S100, a cross center line of a steering module is determined on a ground sample; step S200, a propulsion module is installed on the steering module; step S300, a front center point and a rear center point of the propulsion module are marked at the bottom of the propulsion module; and step S400, the propulsion module is corrected by a laser device, and the steering module is rotated to enable the connecting line of the front center point andthe rear center point of the propulsion module to be parallel to the front and rear center lines of the cross center line. By rotating the steering module in the calibration process, the connecting line between the front center point and the rear center point of the propulsion module is parallel to the cross center line, zero setting of the steering module and the propulsion module is realized, and at this time, the propulsion module and the steering module are in the zero position.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a zero calibration method for a propulsion module. Background technique [0002] During the installation of the ship's propulsion module, it is necessary to zero-align the propulsion module and the rudder steering module to ensure the correctness of the installation and commissioning of the ship's propulsion module. In existing practice, the propulsion module of the propulsion device has no center mark, and the shaft of the propulsion module is located inside the propulsion module. Traditional craftsmanship can't find zero. This results in large errors when calibrating the rudder angle indicator. Contents of the invention [0003] An object of the embodiments of the present invention is to provide a method for zero calibration of a propulsion module, which can conveniently realize zero calibration of the propulsion module. [0004] For reaching above-mentioned purpose,...
