Oil filling process sequence: shell oil filler → oil filling sleeve groove → oil filling sleeve groove → shell oil filling hole → diaphragm → stator. Oil drainage process sequence: rotating stator → diaphragm M+S cycloidal motor Manufacturer → Shell oil distribution hole → oil distribution jacket longitudinal groove → oil distribution jacket groove → shell oil return port. The rotating motion of the rotor includes rotation (rotation in the direction of expanding the high-pressure cavity around the center of the rotor) and revolution (rotation in the direction of deviation from the radius around the center of the stator). The rotation of the rotor is opposite to the revolution direction, and the rotation is transmitted to the output shaft through the linkage shaft. Rotor rotates for 1 cycle special-purpose M+S cycloidal motor The rotor is driven by 42 pressure oil with the maximum volume for 6 revolutions, so the motor has a large emissions.
The manufacturer of the hydraulic motor has explained to us the relevant knowledge about the speed and low-speed stability of the hydraulic motor. The speed of the hydraulic motor depends on the flow of the supply fluid q and the discharge of the hydraulic motor itself v. The hydraulic motor has internal leakage. Not all the liquid entering the motor drives the hydraulic motor to work. Some of the liquid is lost due to leakage, and the actual speed of the motor is lower than the ideal situation. When the working speed of the hydraulic motor is too low, it cannot maintain a uniform speed, and it stops when entering Urumqi M+S cycloidal motor The unstable state is a creeping phenomenon. The high-speed hydraulic motor is required to work at a speed below 10r/min and the low-speed high torque hydraulic motor is required to work at a speed below 3r/min. All hydraulic motors can meet the requirements. Generally speaking, the low-speed stability of low-speed large torque hydraulic motors is better than that of high-speed motors. Due to the large emissions and size of the low-speed high torque motor, the sliding speed of the friction pair will not be too low even if the rotation speed is low special-purpose M+S cycloidal motor Large emissions, relatively small impact of leakage, large rotation inertia of the motor itself, easy to obtain good low-speed stability.
The radial piston hydraulic motor uses a cam ring with a special curve to make each plunger reciprocate several times within one cycle of cylinder block rotation, which is called multi action special-purpose M+S cycloidal motor Internal curve radial plunger hydraulic motor (referred to as internal curve motor) is used. The internal curve motor has the advantages of small size, light weight, radial force balance, small torque ripple, high starting efficiency, stable operation at very low speed, etc. It has been widely used M+S cycloidal motor Manufacturer In marine machinery. Working principle of inner curve motor: the inner wall of the cam ring (housing) is composed of x evenly distributed curved surfaces with the same shape. Each curved surface with the same shape can be divided into two symmetrical sides. The side that allows the plunger set to extend outward is the working section (oil inlet section), and the opposite side is called the oil return section. The number of reciprocating times of each plunger per revolution of the hydraulic motor is equal to the number of curved surfaces of the cam ring x (x is called the number of times of action of the motor).
The valve control system controls the flow by changing the opening of the valve throttle, thus controlling the speed of the actuator. Usually, the reason for low efficiency is the existence of throttling and overflow losses. Almost all mechanical equipment adopts valve control system. The pump control system can realize the stepless control of speed by changing the displacement of variable displacement pump, or control the flow through the combination of multiple constant displacement pumps to achieve the stepwise control of speed. The reason for high efficiency is that there is no throttling or overflow loss. It is widely used in high power hydraulic devices such as pressure processing machinery and plastic machinery. The actuator control system controls the flow by changing the variable hydraulic motor flow of the actuator, or through the joint work of multiple quantitative hydraulic motors, or by changing the action area of the composite hydraulic cylinder. Similar to the pump control system, this system has high efficiency because it has no throttling and overflow losses. It is suitable for traveling machinery, press and other hydraulic equipment.
The weight per unit of electricity is very light. Statistics show that the weight of hydraulic pump and hydraulic motor per unit power is only the generator. 1/10 of the motor, hydraulic pump and hydraulic motor can be as small as 0.0025N/W, and the generator and motor with the same power can be about 0.03N/W. As for size, the former is about 12%~13% of the latter. In terms of output force, it is easy to get extremely high pressure hydraulic fluid with a pump, which will produce great force after being delivered to the hydraulic cylinder. Therefore, hydraulic technology has the advantages of light weight Urumqi Manufacturer The outstanding characteristics of small size and large output are conducive to the miniaturization and miniaturization of mechanical equipment and its control system for high-power operation. Flexible and convenient layout. The configuration of hydraulic components is not restricted by the strict space position, and it is easy to pass according to the needs of the machine. The connection of all parts of the system is realized through pipes, and the layout setting has great flexibility special-purpose M+S cycloidal motor Soft, which can form a complex system that is difficult to form by other methods.
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.
