2.1 Generating the turning force
The high hydraulic supplied from a hydraulic pump flows into a cylinder block (8) through valve casing
of motor (22), and valve plate (20).
The high hydraulic is built as flowing on one side of Y-Y line connected by the upper and lower sides of
piston (12).
The high hydraulic can generate the force, F1=P
×
A (P : supplied pressure, A : water pressure area),
like following pictures, working on a piston.
This force, F1, is divided as N1 thrust partial pressure and W1 radial partial pressure, in case of the
plate of a tilt angle,
α
.
W1 generates torque, T=W1+R1, for Y-Y line connected by the upper and lower sides of the piston as
following pictures.
The sum of torque (
Σ
W1
×
R1), generated from each piston (4~5 pieces) on the side of a high
hydraulic, generates the turning force.
This torque transfers the turning force to a cylinder (8) through a piston; because a cylinder is
combined with a turning axis and spline, a turning axis rotates and a turning force is sent.
