Abstract

The invention provides a method for determining cutter shaft alignment based on a calculation software of ship shaft alignment. According to the technical scheme, basic parameters of the cutter shaftalignment and an auxiliary structure thereof are obtained; an actual shaft is converted into an alignment model parameter table description; a displacement value of each bearing of the cutter shaft alignment under different working conditions is calculated by combining the calculation software of the ship shaft alignment; a calculation model used for calculating and analyzing the cutter shaft alignment is established, and then alignment calculations of a horizontal suspension state and the cutter shaft system under different excavation working conditions are respectively carried out. Accordingto the provided technical scheme, the method for determining the cutter shaft alignment in China is enriched, the alignment calculation of the cutter shaft alignment of a dredger is carried out accurately and reliably, and instructions and advice for the actual installation and verification of the cutter shaft is provided.

Description

technical field [0001] The invention relates to the technical field of marine engineering machinery and equipment, in particular to a method for determining shafting alignment of a reamer based on calculation software for shafting alignment of a ship. Background technique [0002] The cutter suction dredger is in a periodical working state for a long time, and its transmission shafting is subjected to complex stress and load during operation. If the quality of the shafting alignment is not good, the shafting will generate harmful vibrations, resulting in accelerated wear of the bearings and even The fracture of the shaft system directly affects the navigation safety of the ship. Therefore, in order to ensure the long-term normal operation of the shaft system, various factors must be considered comprehensively, a calculation model in line with the actual situation must be established, and the operating state of the shaft system under each working condition is calculated to obt...
