Dispersion locking type rudderstock structure

Abstract

The invention discloses a decentralized locking type rudderstock structure. The decentralized locking type rudderstock structure comprises a decentralized locking mechanism; a dispersed locking mechanism is additionally arranged, a lower linkage screw rod is mounted on the outer side of the lower end of each radial abutting plate, the outer end of each lower linkage screw rod extends into a locking groove through a connecting channel, and meanwhile, a screwing nut is screwed to the outer end of each lower linkage screw rod in a threaded mode; in this way, the screwing nut is rotationally connected to the end face of the inner side of the locking groove in an abutting mode, the radial structural stability of the floating protruding blocks is improved, each floating protruding block is provided with an independent locking structure, the locking structures are evenly dispersed, and therefore even if the radial structures of the individual floating protruding blocks are loosened towards the inner side, the floating protruding blocks can be locked. And the radial stability of the whole structure is not influenced.

Description

technical field [0001] The invention relates to a decentralized locking rudder stock structure. Background technique [0002] The rudder stock 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 by the rudder to the rudder device. Its reaction force enables the ship to turn; generally, the upper end of the rudder stock is connected to the rudder handle, and the lower end of the rudder stock is connected to the rudder blade. In the existing assembly process, the rudder stock is generally installed in the middle of the rudder bearing by rotation There is generally a rotating ring on the outside of the rudder stock, and an annular slot around the middle of the rudder bearing. During the assembly process, due to the different sizes, the radial position and axial position of the rotating ring must be highly matched and limited with the position of the annular slot, which makes the asse...

[0002] The rudder stock 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 by the rudder to the rudder device. Its reaction force enables the ship to turn; generally, the upper end of the rudder stock is connected to the rudder handle, and the lower end of the rudder stock is connected to the rudder blade. In the existing assembly process, the rudder stock is generally installed in the middle of the rudder bearing by rotation There is generally a rotating ring on the outside of the rudder stock, and an annular slot around the middle of the rudder bearing. During the assembly process, due to the different sizes, the radial position and axial position of the rotating ring must be highly matched and limited with the position of the annular slot, which makes the assembly of the rudder stock inflexible and makes the scope of use strictly restricted. restrictions, and the processing accuracy requirements are relatively strict, and the stability of the structure needs to be improved
