Description

technical field

[0001] The invention relates to a method for installing a main engine shafting system, in particular to a method for installing a main engine shafting system with three main engines and three propellers in a ship. Background technique

[0002] The stern shaft drives the propeller. Its shaft installation is relatively easy. In order to meet the force requirements of large-scale transportation with a concentrated load of more than 500 tons, and to meet the force requirements of uniformly distributed loads of transport trucks, some ships are propelled by three engines and three propellers, and diesel engine power devices arranged in the middle and tail models the design of. The output end of each main engine drives the propeller through couplings, reduction gearboxes, intermediate shafts, stern shafts, etc. The shaft system is equipped with intermediate shaft, intermediate bearing, stern shaft, stern bearing, front and rear sealing devices and manual brake de...
