Marine Rudder Stock
The marine rudder stock is the shaft of the rudder blade rotation, and is used to bear and transfer the force acting on the rudder blade, and the force given by the rudder to the steering device. The lower part is connected with the rudder blade, and the upper part is connected with the steering device. It is typically made from high-strength steel or stainless steel to withstand corrosion and mechanical stress. It usually also require effective sealing apparatus to prevent water ingress into the steering system, which otherwise could lead to corrosion and operational issues.
Overview
In order to facilitate the assembly of the rudder, the top of the upper rudder stock is equipped with a sling ring, and the lower end is equipped with a flange joint connected with the flange on the rudder blade. The connection includes vertical flange connection, vertical embedded connection and other forms of connection. The horizontal flange joint is commonly used at present.
When the rudder stock and rudder blade are turned to the maximum rudder angle of the opposite side, there is a gap of 30mm between the upper and lower flange edges, and the rudder can be removed without removing the rudder stock. A bushing should be installed at the friction area of the rudder pole to prevent wear. The bushing is usually made from bronze or other copper material.
