Working principle and characteristics of cycloid hydraulic motor

As we all know, the cycloid hydraulic motor has a wide range of uses, mainly used in the slewing mechanism of a variety of machinery such as agriculture, fishery, light industry, lifting and transportation, mining, and construction machinery. Because of its superior structure and performance characteristics, it is loved by the majority of users, so how much do you know about it? Do you know the working principle and main features of this device? Next, let's talk about the working principle and characteristics of the cycloid hydraulic motor, hope it will be helpful to everyone.
Cycloidal hydraulic motor is a kind of internal meshing cycloidal gear hydraulic motor made by the principle similar to planetary reducer (less tooth difference principle), referred to as cycloidal motor
►Working principle of cycloid hydraulic motor:
Cycloidal hydraulic motor is a kind of internal meshing cycloidal gear hydraulic motor made by using the principle similar to planetary reducer (less tooth difference principle), referred to as cycloidal motor.
The rotor and the stator are a pair of cycloidal needle-tooth meshing pairs. The rotor has a short-width epicycloid equidistant tooth profile with Zi (Zi=6 or 8) teeth. The stator has a Zi+1 circular arc needle-tooth profile. The rotor and the stator form Zi+1 closed inter-tooth volume. Half of them are in the high pressure zone and half are in the low pressure zone. The stator is fixed, the center of the ring gear is 02, and the center of the rotor is Oi. The hydraulic torque generated by the rotor under the action of the pressure oil makes planetary motion around the stator center 02 with the eccentricity g as the radius. That is, the rotor rotates around its own center Oi on the one hand, and on the other hand its center Oi reverses around the stator center 02. When the rotor is rolling along the stator, its inlet and return oil cavity are constantly changing, but it is always divided into two sides by the connecting center line Oi 02. One side is for oil inlet, and the volume of the cavity gradually increases; the other side is for oil discharge, and the volume Gradually shrink, squeeze out the oil, pass the oil distribution mechanism, and then drain to the oil tank through the oil outlet of the oil motor.
►The cycloidal hydraulic motor is an integral form of the output shaft and the distribution valve. The insert-type stator and rotor pair cycloidal hydraulic motor has main features:
1. Adopting end face flow distribution and axial face flow distribution, the structure is simple and compact, and the flow distribution accuracy is high;
2. Adopting toothed stator and rotor pair, high mechanical efficiency, long service life under high pressure;
3. Adopting double-joint angular ball bearings, which can bear larger radial and axial loads, with low friction and high mechanical efficiency.
4. Good flow distribution mechanism design, with the characteristics of high distribution accuracy and automatic wear compensation.
5. The motors are allowed to be used in series and in parallel, and the external drain port should be connected when used in series.
6. The tapered roller bearing support design has a large radial load capacity, so that the motor can directly drive the working mechanism.
7. A variety of installation and connection forms such as flanges, output shafts, and oil ports.
