However, there are many defects in the current rudder stock. The bottom of the rudder stock is soaked in seawater and river water for a long time. Quickly assembling the protective cover has become the primary problem to be solved. In addition, the material properties of forged steel are easy to cause wear on the surface of the rudder stock, which will reduce the efficiency of torque transmission of the rudder stock, scrap the whole, and increase the cost of the enterprise

The invention discloses an easily-split rudderstock for a ship. The easily-split rudderstock comprises an upper rudderstock body, a lower rudderstock body and a protective casing, wherein the upper rudderstock body and the lower rudderstock body are connected end to end; the protective casing is connected to the lower end of the lower rudderstock body in a sleeving manner and further comprises a rotary locking mechanism; the lower rudderstock body comprises a left semi-ring and a right semi-ring; a cross-under bar is arranged on one side of the left semi-ring; a cross-under groove is formed in one side of the right semi-ring and extends downwards from the upper end of the right semi-ring to the middle of the right semi-ring; and the left semi-ring is inserted into the cross-under groove from the upper end of the right semi-ring via the cross-under bar. According to the easily-split rudderstock disclosed by the invention, the upper rudderstock body and the protective casing are of a movably connected structure, detachment and assembly are rapid, only a rotary screw needs to be twisted in the whole motion process, and the operating process is simple and convenient.
Description
technical field [0001] The invention relates to the field of marine accessories, in particular to a marine rudder stock. Background technique [0002] The rudder stock refers to the rotating rod that connects the rudder blade and the steering gear or the tiller, and transmits the rudder torque. As we all know, the rudder stock is one of the most important components in the shipbuilding industry. The current rudder stock is generally a one-piece structure of forged steel. However, there are many defects in the current rudder stock. The bottom of the rudder stock is soaked in seawater and river water for a long time. Quickly assembling the protective cover has become the primary problem to be solved. In addition, the material properties of forged steel are easy to cause wear on the surface of the rudder stock, which will reduce the efficiency of torque transmission of the rudder stock, scrap the whole, and increase the cost of the enterprise.
