Along the revolution direction of the rotor, the volume of the tooth cavity at the front side of the connection between the rotor and the stator becomes smaller, which is an oil discharge cavity, and the volume at the rear side becomes larger. When the connecting line passes through the two tooth roots of the rotor, the oil inlet ends and the largest tooth cavity appears. When the connecting line passes through the two tooth tops of the rotor, the oil drainage ends and the smallest tooth cavity appears. In order to ensure the continuous rotation of the rotor, it is necessary to have the same regular oil distribution mechanism to cooperate with it, so that the tooth cavity at the front side of the connecting pipeline is always connected with the oil drain port, and the rear side is connected with the oil inlet port. As mentioned above, the oil distribution mechanism consists of a housing and an oil distribution sleeve. The 12 longitudinal grooves (x) on the oil distribution sleeve and the 12 intervals formed by the oil distribution groove face the root and top of the rotor through the positioning device, which proves that when the largest and smallest cavities occur, the oil distribution hole of the housing can be closed, thus separating the oil inlet groove and oil outlet groove of the oil distribution sleeve.

In the middle opening system, the main reversing valve of the middle opening system is in the middle position, through which the hydraulic pump is unloaded, and the liquid returns to the oil tank under low pressure. This kind of system generally uses constant displacement pump as oil source; When the reversing valve is in the middle position, the energy transmission starts with a low value that is basically zero, and the energy rises after changing, so that the pressure liquid enters special-purpose Hydraulic cycloid motor The actuator acts on the load; When the reversing valve is in the middle position, the internal leakage is very small. Generally, when the same function is achieved, the energy consumption of the intermediate open circuit is smaller. in Qinghai special-purpose Open system is mostly used for working conditions requiring intermittent movement or supporting load, such as prime movers that do not want to start and stop frequently. The system has high efficiency, and needs to use makeup oil pump and flushing valve for oil makeup and heat exchange.

Cycloidal hydraulic motor, as a kind of construction machinery equipment with small price increase and light weight, is also widely used in daily life. Cycloidal hydraulic motor is a kind of motor, which is essential for some equipment. In fact, the operation of all hydraulic systems is almost the same. This cycloidal hydraulic motor is widely used Qinghai special-purpose It is used in construction, manufacturing, mining and other industries, so pay attention to daily maintenance when using the motor to ensure the service life of the cycloidal hydraulic motor. In order to keep the whole system in a stable state, it is necessary to ensure that the motor function has a constant pressure, ensure that the hydraulic system is normal, and ensure that the pressure in the system is not Hydraulic cycloid motor Price leak.

Most of its hydraulic system uses working medium, such as hydraulic oil with continuous fluidity, which converts the mechanical energy of the prime mover driving the pump into the pressure energy of the liquid through the hydraulic pump, and sends it to the actuator (hydraulic cylinder, hydraulic motor or swing hydraulic motor) through various control valves, such as pressure, flow, direction, etc., to convert it into mechanical energy to drive the load. This hydraulic system is generally composed of the following parts: power source, actuator, control valve, hydraulic auxiliary device and hydraulic working medium, which play their respective roles: power source: prime mover (motor or internal combustion engine) and hydraulic pump, whose role is to convert the mechanical energy generated by the prime mover into the pressure energy of liquid, and output oil with a certain pressure;

As a kind of hydraulic transmission device, hydraulic motor has been widely used in many places. In fact, I have seen it on many occasions. The main application fields are. 1. The hydraulic motor has convenient speed regulation, which can be adjusted infinitely from 0 to the maximum speed according to the adjustment of the hydraulic valve. The motor itself does not need special design and has low cost. This is much cheaper than motor+reducer, or variable frequency motor and servo motor. 2. The hydraulic system has strong anti overload capacity and relies on the overflow valve for protection, allowing a long time special-purpose Hydraulic cycloid motor (Relatively) Frequent overload, easy to recover under overload, no damage to equipment, no restart of equipment. 3. The hydraulic system is characterized by high energy density. For motors of the same power, hydraulic motors are much smaller than motors Hydraulic cycloid motor Price , much lighter. And it is easy to apply to mobile devices. 4. The hydraulic motor is totally enclosed and can be safely used in dusty, wet (even underwater) and flammable environments, which is much more reliable than explosion-proof (flameproof) motors.
