Swinging disc type oil cylinder motor

Abstract

The invention discloses a swinging disc type oil cylinder motor. The swinging disc type oil cylinder motor comprises a crankshaft, a swinging disc, oil cylinders, oil distribution valves, shifting forks, connecting rods and a shell, wherein the swinging disc is mounted on the crankshaft, the oil cylinders are connected with the swinging disc and the oil distribution valves, and the shifting forks are mounted on the oil cylinders; one end of each connecting rod is connected with the corresponding oil distribution valve, and the other end of each connecting rod is connected with the corresponding shifting fork; and the crankshaft, the oil cylinders and the oil distribution valves are all mounted on the shell. According to the swinging disc type oil cylinder motor, the shifting forks and the connecting rods act to make the oil distribution valves conduct oil distribution correspondingly, the multiple oil cylinders are made to make different motions, the swinging disc is pushed to swing accordingly, the crankshaft is made to rotate, and thus a load is driven to move. According to the swinging disc type oil cylinder motor, planar oil distribution through an oil distribution disc is not needed anymore, the structure is simple, the number of rotating components is reduced, oil distribution is accurate, the probability of abrasion and oil leakage during oil distribution can be lowered, the reliability is high, and the service life is long.

Description

technical field [0001] The invention relates to the field of hydraulic component design, in particular to a swing disc oil cylinder motor. Background technique [0002] The hydraulic motor is the actuator in the hydraulic system. It converts the hydraulic pressure energy provided by the hydraulic pump into the mechanical energy of its output shaft, and provides the load with speed and torque. Traditional hydraulic motors mainly include gear motors, vane motors, and plunger motors. The internal structures of these motors are different, but the principle and structure of their oil distribution mechanisms are basically the same. The oil distribution plate, and then relies on the rotation of the crankshaft and other mechanisms to drive the oil distribution plate to rotate for oil distribution. This kind of oil distribution mechanism has a complex structure, high cost, serious oil leakage during oil distribution, and rapid wear, which seriously affects the life of the hydraulic m...
