Steering engine

A rowing machine is an installed shipboard hydraulic machine that serves the ( " put the helm " ) by the helmsman at the setting of rudder angle to reinforce exerted muscle force so that it counteracts the mechanical and hydrodynamic forces are overcome.

The tax effect on the ship is achieved by the set rudder in the driving current and the propeller power. The control forces resulting from the pressure distribution around the rudder, which are now carried out mainly as a wing. It predominantly electro-hydraulic plunger or rotary wing rowing machines are used today. Are prescribed by the classifications two independent rowing machines.

Plunger rowing machine

It consists of an electrically driven hydraulic oil pump ( hydraulic pump ), and the steering apparatus having two differential pistons and four plungers. As pressure oil pump is a piston pump stroke motion is often used. The piston rods of the plunger rowing machine to act straight guidance in a sliding sliding blocks, which act on the tiller. The tiller is positively connected to the rudder, so can be adjusted at the stroke axial piston pump, a hydraulic flow rate. Wherein a path of the piston is formed, which in turn causes a rotation angle of the rudder. At the rudder shaft is a feedback, except for mechanical feedback often a resolver that reflects the actual value of the rudder angle in real time on the bridge on the rudder angle indicator.

Rotary vane steering gear

In the hydraulic rotary vane steering gear a stroke of the axial piston pump causes a rotational movement of the rudder post. The building up in the hydraulic spaces between the mobile with the rudder shaft rotary wings and attached to the housing partitions pressure causes a force and the lever arm a moment. On the suction side of the HydrauliköI flows back into the hydraulic system.
