A hydraulic motor is a device that converts hydraulic energy into mechanical energy, which uses the pressure energy of a liquid to generate power and drive the actuator to work. The hydraulic motor is mainly composed of the following parts:
Housing: The outer frame of a hydraulic motor, usually made of metal material, to support and protect the internal parts.
Rotor: A key component in a hydraulic motor, it produces rotational motion through the pressure of a liquid. The rotor has sealed cavities inside the rotor that the liquid enters and pushes the rotor to rotate under pressure.
Oil Distribution Mechanism: The oil distribution mechanism is responsible for distributing the liquid into the various cavities of the rotor to ensure that the rotor can rotate smoothly. The oil distribution mechanism is usually composed of oil distribution pan, oil distribution shaft and other parts.
Bearings: Bearings are used to support the rotor and stator, reducing friction and wear between them.
Seals: Seals for hydraulic motors are used to ensure tightness between the various cavities and prevent liquid leakage.
Transmission mechanism: The transmission mechanism is used to transmit the rotary motion of the rotor to an external actuator, such as hydraulic cylinders, hydraulic motors, etc.
The working principle of a hydraulic motor is based on Pascal's principle, which states that the pressure on a liquid inside a closed container is equal in all directions. When the liquid enters the cavity of the hydraulic motor, it is subjected to pressure that pushes the rotor to rotate. By varying the flow and pressure of the liquid, the speed and torque of the hydraulic motor can be controlled.
Hydraulic motors have many advantages, such as compact structure, small size, light weight, reliable work, etc. It can work in harsh environments, is insensitive to oil contamination, and is easy to achieve stepless speed change and forward and reverse control. Therefore, hydraulic motors are widely used in various mechanical equipment, such as injection molding machinery, ships, construction machinery, construction machinery, etc.
It should be noted that the hydraulic motor needs regular maintenance and maintenance during use to ensure that it works properly. At the same time, when choosing a hydraulic motor, it is necessary to choose according to the actual working requirements and conditions to ensure that it can meet the requirements of use.
