Operating mechanism:

Since the curve of the swing cylinder and the piston always passes through the center of the crankshaft bearing sleeve, the swing cylinder piston has no lateral force. High pressure oil enters the oil distribution plate rotating with the crankshaft from the oil inlet of the oil distribution plate, and then enters the balance chamber at the lower part of the piston through the orifice at the upper part of the piston through the housing flow channel and the swing cylinder trunnion. At this time, the piston with high pressure oil is pushed away from the shaft center by the crankshaft, The piston in the piston cavity is pushed away from the shaft center, and the volume of the piston in the piston cavity decreases. The low-pressure oil is discharged into the oil return port through the low-pressure channel at the swing cylinder ear ring from the housing flow channel. Each piston is connected to the oil return port in turn. At this time, the piston is driven by the crankshaft, Parker cycloid hydraulic motor The piston in the piston is pushed away from the axle center, and the volume of the piston chamber decreases, Danfoss cycloid motor The low-pressure oil flows through the channel at the swing cylinder ear ring, and each piston is discharged into the oil return port. Each high-pressure piston is connected to the oil return port in turn, and the driving torque of each high-pressure piston to the center of the output shaft is consistent. After changing the oil flow direction, if the oil distribution plate is rotated by 180 °, it can be changed Hydraulic motor Steering of.

Assembly can also realize the turnover of hydraulic motor.
