Marine rudder bearing rudder lever connecting structure based on abrasion ring body

Abstract

The invention discloses a marine rudder bearing rudder lever connecting structure based on an abrasion ring body, which comprises a rudder lever, a rudder bearing, an adjusting lever, an elastic floating ring, an abrasion ring body and a sealing ring. The inside of the rudder bearing is provided with an annular cavity; the annular cavity is provided with an abrasive ring body; a sealing ring is arranged between the abrasive ring body and the inner wall of the annular cavity; the abrasive ring is made of polytetrafluoroethylene material; the inner side of the abrasion ring body is provided withan abrasion ring groove. The invention prevents friction between the rudder stem and the rudder carrier.

Description

technical field [0001] The invention relates to a ship rudder support and rudder stock connection structure based on a wear ring body. Background technique [0002] The rudder bearing is an important device in the rudder system of a ship. The rudder bearing bears the axial and radial loads from the rudder stock and rudder blades to ensure that the rudder blades rotate left and right with the rudder stock, thereby changing the course of the ship or keeping the ship sailing in a straight line; The rod refers to the shaft on which the rudder blade rotates, which is used to bear and transmit the force acting on the rudder blade and the force given to the rudder device by the rudder, that is to say, the steering gear rotates the rudder blade through the rudder stock, and the rudder blade bears the force of water on the rudder blade. The reaction force makes the ship turn; the existing rudder bearing is sleeved on the outside of the rudder stock, and the rudder bearing is used to ...

[0002] The rudder bearing is an important device in the rudder system of a ship. The rudder bearing bears the axial and radial loads from the rudder stock and rudder blades to ensure that the rudder blades rotate left and right with the rudder stock, thereby changing the course of the ship or keeping the ship sailing in a straight line; The rod refers to the shaft on which the rudder blade rotates. It is used to bear and transmit the force acting on the rudder blade and the force given to the rudder device by the rudder. The reaction force makes the ship turn; the existing rudder bearing is sleeved on the outside of the rudder stock, and the rudder bearing is used to limit and support the rudder stock; the long-term friction loss between the existing rudder bearing and the rudder stock will cause the connection Instable, and the sealing performance is also reduced
