HYDRAULIC MOTOR OPERATION
1. Hydraulic Motor operation.
The high pressure oil from the hydraulic pump goes to the cylinder block (104) through the rear
flange (101) of the motor and the brake valve device and the timing plate (109). This high
pressure oil acts only on the single side of the line Y1-Y2 which connects the bottom dead
center and the top dead center of the piston (105) stroke. The oil, after flowing into the side of
the cylinder block (104), exerts force on each piston (4 or S pieces) and generates force F (p kg/
cm x A cm
2 ). The force F is exerted on the swash plate (103): as the swash plate (103) is tilted
with respect to the driving shaft (102) by a degrees, the force F is divided into two resultant
forces F2 and F3. Among these forces, radial force F3 develops torque T (F3 x ri) with respect
to each Yl-Y2 line. The combined torque T(Z(F3 x ri)), which is a rotation force, rotates the
cylinder block through pistons (105). The cylinder block is coupled with the driving shaft by a
spline, and the driving torque is transferred to the shaft.
