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 propeller includes a sealed casing 1, an oil tank 2 arranged on the sealed casing, and an input stub shaft 3, a power shaft 4, a mandrel 5, a propeller shaft 6, an input stub shaft 3 and The power shaft 4 is connected by a clutch 7. The power shaft 4 and the mandrel 5, and the mandrel 5 and the propeller shaft 6 are all meshed and driven by the bevel gear 8. The bottom of the oil tank 2 is connected with the sealed housing 1, and the oil tank 2 is provided with There is an overflow pipe 9 extending from the mandrel 5 through the bottom of the oil tank 2 to the top of the oil tank 2. The mandrel 5 is provided with a channel 10 through which the lubricating medium returns to the oil tank 2, and the channel 10 is in communication with the overflow pipe 9. 5 The outer casing is provided with 6 a pumping ring 11 that r...

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, and in particular to a design method of a pumping ring used for lubricating and cooling a rudder propeller. Background technique [0002] Rudder and propeller are the main components of the ship's propulsion system. The rudder can be used to control the direction of the ship's travel, and the propeller is 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 ordinary propellers, and can also change the thrust direction within 360°. It has the functions of rudder and propeller, and can flexibly change the position and heading of the ship. It is widely used in cruise ships, engineering ships, offshore platforms and other occasions that require high mobility or require dynamic positioning. [0003] The rudder propeller includes a sealed shell and a transmission mechanism installed in the sealed shell. The transmi...
