Hunting gear Mechanism

The steering gear system above consists of the telemotor which receives a signal from the bridge wheel. This ats on the hunting gear.

The hunting gear moves displacing a control rod, this rod acts on the pump displacement control gear to alter the delivery from the pump. The delivery from the pump causes the ram to move rotating the rudder stock and hence the rudder. The other end of the hunting gear is mounted on the rudder stock. The rotation of rudder stock moves the hunting gear returning the operating rod for the pump to the neutral position onces the rudder has reached the correct angle.

This mechanism in the steering gear system is the feedback system which transmits the position of rudder to pump control lever through floating lever.

One end of floating lever is connected to hunting lever. Another end connected to telemotor receiver. Mid of the floating lever connected to the pump control lever.

When pump control lever is in “B” position, pump will not discharge.

When the movement is given at bridge, Telemotor receiver moves the floating lever from A to A1. (STBD)

When this happens, pump control lever moves from B to B1.

As it moves from B to any other point, pumps will start pumping the pressurized hydraulic oil to ram cylinders. It will make the rudder to move port direction. ie, from C to C1.

Once the port position is reached, the pump control lever will reach to the position B which stops the pump and there will be no oil supply. Thus, rudder stops at that position. Vice versa for the other direction.
