Embodiment

[0060] The embodiment of the present invention provides a design method for lubricating and cooling the pumping ring of the rudder propeller, see figure 1, the rudder paddle includes a sealed housing 1, an oil tank 2 arranged on the sealed housing, and an input short shaft 3, a power shaft 4, a core shaft 5, a propeller shaft 6 arranged in the sealed housing 1, the input short shaft 3 and The power shaft 4 is connected through the clutch 7, and the transmission between the power shaft 4 and the mandrel 5, and between the mandrel 5 and the propeller shaft 6 is through the meshing transmission of the bevel gear 8. There is an overflow pipe 9 extending from the bottom of the mandrel 5 through the oil tank 2 to the top of the oil tank 2. The mandrel 5 is provided with a channel 10 for the lubricating medium to return to the oil tank 2. The channel 10 communicates with the overflow pipe 9. The mandrel 5 is provided with a pumping ring 11 that rotates synchronously with the mandrel ...

Abstract

The invention discloses a design method of a pumping ring for lubricating and cooling an azimuth thruster, and belongs to the technical field of ship propulsion. The design method comprises the following steps that the target flow of a lubricating medium is determined according to the cooling requirement of the azimuth thruster; the design parameters of the pumping ring are selected, and comprise one or more of the external diameter of the pumping ring, the internal diameter of the pumping ring, the axial thickness of the pumping ring, and the lead angle, the width and the depth of the thread in the pumping ring; the driving flow and the leakage flow are calculated on the basis of the selected design parameters, wherein the driving flow is the flow of the lubricating medium under the driving action of the pumping ring, and the leakage flow is the leakage rate of the lubricating medium; and when the difference between the driving flow and the leakage flow is equal to the target flow, the pumping ring is designed according to the selected design parameters. The design method can achieve the purpose of lubricating and cooling the azimuth thruster by the pumping ring meeting the cooling requirement of the azimuth thruster.

Description

technical field [0001] The invention relates to the technical field of ship propulsion, in particular to a design method for a pumping ring used for lubricating and cooling 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 a sealed casing and a transmission mechanism installed in the sealed casing. The transmission mechanism includes an input short shaft and a power shaft arranged horizontally on the upper part, a mandrel a...
