Embodiment

[0054] The embodiment of the present invention provides a manufacturing method of the rotary unit in the rudder oar, which can be applied to the telescopic full-rotation rudder oar device, and is especially suitable for the manufacture of the rotary unit in the rudder oar of the 300-lift pipe-laying ship.

[0055]Specifically, the rudder oar includes a propulsion unit and a rotary unit. The propulsion unit includes an input shaft, a transmission shaft, a propeller shaft, an upper bevel gearbox with an upper bevel gear inside, a lower bevel gearbox with a lower bevel gear inside, the input shaft and the transmission shaft are driven through the upper bevel gear, and the transmission shaft It is engaged with the propeller shaft through the lower bevel gear. The slewing unit includes a slewing motor, a slewing bearing, an upper slewing flange, a slewing tube, and a lower slewing flange. The slewing motor and slewing bearing are arranged on the upper bevel gearbox. The flange and...

Abstract

The invention discloses a manufacturing method of a rotary unit in a steering oar, and belongs to the technical field of ship propulsion. The manufacturing method comprises the steps that a plurality of stainless steel cylinders coating a rotary pipe and two stainless steel semi-circular rings coating a circular ring are manufactured, and a plurality of plug welding holes are formed in the stainless steel semi-circular rings; the plug welding holes are welded in a plug welding manner, the two stainless steel semi-circular rings are fixed to the circular ring, and a butt weld of the two stainless steel semi-circular rings is welded; surfacing is carried out on two rotary bodies; a rotary flange is assembled on the rotary pipe; and the multiple stainless steel cylinders are arranged on the rotary pipe in a sleeving manner through the shrinkage fit process. The rotary flange is coated with a stainless steel layer through the welding technology, and the problems which cannot be solved by the shrinkage fit technology and the problems about the electroplating technology cost and the period are solved.

Description

technical field [0001] The invention relates to the technical field of ship propulsion, in particular to a method for manufacturing a rotary unit in a rudder propeller. Background technique [0002] Rudders and oars are the main components of a ship's propulsion system. The rudder can be used to control the direction of the ship, and the oars are used to provide propulsion for the ship's travel. The rudder propeller is a new type of ship propulsion device. It can generate thrust like a common propeller, and can also change the thrust direction within a range of 360°. Widely used in cruise ships, engineering ships, offshore platforms and other occasions that require high maneuverability or require dynamic positioning. [0003] The rudder oar includes propulsion unit, slewing unit and so on. The propulsion unit includes an input shaft arranged horizontally on the upper part, a transmission shaft arranged vertically in the middle, and a propeller shaft arranged horizontally o...
