Rotary pipe hermetical installation structure of fully rotary steering oar

Abstract

The invention relates to a rotary pipe hermetical installation structure of a fully rotary steering oar. According to the technical scheme provided by the invention, the rotary pipe hermetical installation structure of the fully rotary steering oar is characterized in that: a rotary pipe is vertically arranged in a rudder tube of a trunk; the upper end of the rotary pipe is connected to a rotary supporting flange; a bearing is arranged between the rotary pipe and the rudder tube; the rotary pipe and the rudder tube rotate relative to each other; a shaft sleeve is sleeved on the rotary pipe; a sealing socket, an upper sealing transparent cover and a lower sealing transparent cover are sleeved on the shaft sleeve; the sealing socket is fixedly connected to the rudder tube; a watertight seal is arranged between the upper part of the sealing socket and the shaft sleeve; the watertight seal is packaged through the upper sealing transparent cover arranged on the upper end face of the sealing socket; an oil seal is arranged between the lower part of the sealing socket and the shaft sleeve; and the oil seal is packaged through the lower sealing transparent cover arranged on the lower end face of the sealing socket. The rotary pipe hermetical installation structure has the advantages of craft, compact and reasonable structure, capability of guaranteeing flexible and stable rotation of the rotary pipe and very good sealing property.

Description

technical field [0001] The invention relates to an accessory part of a ship propulsion device, in particular to a sealing installation structure of a rotary tube of a full rotary rudder propeller. Background technique [0002] Rudders and oars are the main components of the ship's propulsion system. The rudder is used to control the direction of the ship, and the oars provide the driving force for the ship. In the prior art, the oars and rudders on ships are separated and work in combination. There are several disadvantages in the working process: (1) The angle of rudder rotation cannot be completely in place under certain circumstances, and cannot To obtain the maximum thrust and rudder effect, the maneuverability and maneuverability of the ship are insufficient. (2) The high-power, high-speed rudder propeller power transmission shafting has problems such as torsional vibration, rotary vibration and system heating during operation, which affect the working stability and s...

Problems solved by technology

In the prior art, the oars and rudders on the ship are separated and work in combination. There are several disadvantages in the working process: (1) The angle of rudder rotation cannot be completely in place under certain circumstances, and cannot To obtain the maximum thrust and rudder effect, the maneuverability and maneuverability of the ship are insufficient

(2) The high-power, high-speed rudder propeller power transmission shafting has problems such as torsional vibration, rotary vibration and system heating during operation, which affect the working stability and service life of the transmission shafting

(3) The design and manufacture of high-power, high-strength spiral bevel gears have extremely high requirements, high precision requirements, and expensive manufacturing costs
