Cycloid hydraulic motor working principle
The working principle of the cycloid hydraulic motor is mainly based on the principle of small tooth difference. It is a kind of internal meshing cycloid gear hydraulic motor.
The core components of such a motor include a rotor and a stator, which form a pair of cycloidal needle tooth meshing gears. The rotor has a specific number of teeth (usually 6 or 8 short-amplitude ectrochoidal equidistant line tooth profile), while the stator has a circular arc needle tooth profile with one more tooth than the rotor. This design results in a specific interdental volume between the rotor and the stator, which is divided into a high pressure zone and a low pressure zone, with half of the volume in the high pressure zone and the other half in the low pressure zone.
When hydraulic oil enters the hydraulic motor, it pushes the rotor to move between the teeth of the stator, thereby generating rotational motion. Under the action of the hydraulic torque generated by the pressure oil, the rotor rotates around the center of the stator with the eccentricity as the radius, and rotates at the same time. This rotary motion includes rotation and revolution, the direction of rotation is opposite to the turnover direction of the high-pressure oil chamber, and the revolution is carried out around the center of the stator.
During the rotation of the rotor, the oil inlet and return chambers are constantly changing, but they are always divided into two sides by the connecting line. One side enters oil, and the volume gradually increases; the other side discharges oil, and the volume gradually decreases. In this way, the oil is squeezed out and passes through the oil distribution mechanism, and finally discharged from the output end of the motor, thereby realizing the conversion of liquid pressure energy to mechanical energy.
The cycloid hydraulic motor is characterized by its high efficiency and low noise, as well as the ability to smoothly output low-speed rotation.
