The oil distribution sleeve is synchronized with the rotor, so that the rotor rotates once, and the seven oil distribution holes on the housing are closed 840 times by the twelve diaphragms of the oil distribution sleeve, while the rotor and stator form the largest and smallest closed cavities respectively 1420 times, collectively referred to as the seal cavity. In the circle of the oil distribution hole of the closed housing, the oil inlet and outlet of the rotor have three chambers respectively, one Hefei Cycloid hydraulic motor The cavity is closed. When the rotor is transferred from the smallest enclosed cavity to the next largest enclosed cavity, before the rotor is transferred from the largest enclosed cavity to the next smallest enclosed cavity, oil is supplied to four cavities and three cavities special-purpose Cycloid hydraulic motor Drain the oil.
Its basic types are gear type, screw type, vane type and axial plunger type. Its main characteristics are high speed, small moment of inertia, convenient starting and braking, adjustment (speed adjustment and special-purpose Cycloid hydraulic motor Reversing) High sensitivity. As the output torque of high-speed hydraulic motor is generally small, it is also called high-speed small torque hydraulic motor. Its basic type is radial plunger type, in addition, there are axial plunger, vane type, gear type and other structural types. Low speed hydraulic motors are mainly characterized by large displacement, large volume and low speed (sometimes Cycloid hydraulic motor Manufacturer It can rotate a few revolutions per minute or even a few revolutions per minute), so it can be directly connected to the working mechanism; It does not need a speed reducer, greatly simplifying the transmission mechanism. Usually, the output torque of low-speed hydraulic motor is large, so it is also called low-speed high torque hydraulic motor.
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 Cycloid hydraulic 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 Hefei 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.
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 Hefei 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 Cycloid hydraulic motor Soft, which can form a complex system that is difficult to form by other methods.
System for fixed equipment. This hydraulic system is mostly an open cycle system, including machine tools (workpiece clamping, worktable feeding, direction exchange, spindle drive), presses (pressing, blank holder, direction exchange, workpiece ejection), die-casting machines and injection molding machines (mold closing, demoulding, preforming, injection mechanisms), medical devices, garbage compression and other mechanical devices Hefei special-purpose System of standby and working devices. The hydraulic system for traveling equipment includes both open circulation system and closed circulation system, including vehicle driving (traveling drive, steering, braking and working equipment Cycloid hydraulic motor Manufacturer ), material conveying, loading, unloading and conveying equipment (conveying mechanism, transposition mechanism), various systems of aviation, space and navigation engineering.
