TORQUE CONVERTER.
a. The Torque Converter (Figure 1-53) is a device which multiplies the torque or twisting force of the diesel
engine. This increased torque is used to drive the anchor winch.
b. A Torque Converter consists of three basic parts. The impeller or pump is driven by the engine. The impeller
is a ring of metal blades which turn in oil. The turbine is made up of three rings of blades and is connected to the anchor
winch shaft. The stator or housing contains two sets of stationary blades.
c. When the impeller turns in oil the first ring in the turbine moves. The fluid is then directed to the first set of
blades in the stator. The stator directs the fluid to the second ring in the turbine. The fluid is then directed through two
sets of blades of the stator and turbine rings.
d. Normally, the action of the impeller-causes the turbine to move freely. The fluid passes through the converter
easily and quickly, striking each stator blade at a slight angle. But, when a load is present, the turbine slows down. The
fluid strikes the blades at a greater angle. The torque relayed through the turbine will increase to five times the input
torque. This increased torque moves the anchor winch cable drum.
