Positioning and fastening type rudder bearing

Abstract

The invention discloses a positioning and fastening type rudder bearing which comprises a rudder bearing body, a rudderstock, a transverse driving mechanism, an axial driving mechanism and a fastening mechanism. A fastening mechanism is additionally arranged, a fastening screw rod is installed at the upper end of a movable clamping plate, the upper end of the fastening screw rod penetrates through a penetrating channel of a penetrating positioning plate and then extends to a fastening groove, and the upper end of the fastening screw rod is rotationally connected with a fastening nut in a threaded mode; in this way, the fastening nut is rotationally connected to the upper side face of the penetrating connection positioning plate in an abutting-against or separating mode, so that the movable clamping plate is fastened and positioned, and the movable clamping plate more stably abuts against and clamps the abutting-against ring bodies on the outer sides of the periphery of the middle of the rudderstock.

Description

technical field [0001] The invention relates to a positioning fastening type rudder bearing. 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 limit the support of the rudder stock; the...
