As far as energy conversion is concerned, the hydraulic pump and hydraulic motor are connected as reversible hydraulic components, and the working fluid can be input into any kind of hydraulic pump to make it become a hydraulic motor; On the contrary, when the main shaft of the hydraulic motor rotates under the action of external force High torque cycloidal hydraulic motor Price It can also become a hydraulic pump. Because they all have the same basic structural elements, namely sealed and recyclable volume and corresponding distribution mechanism. However, the working environment of hydraulic motor and hydraulic pump is different want to buy High torque cycloidal hydraulic motor The performance requirements are also different. Therefore, there are many differences between the hydraulic motor and the hydraulic pump of the same model. The first hydraulic motor should be positive and negative, so its internal structure should be symmetrical; The speed range of the motor must be large enough, especially its minimum stable speed must have certain requirements.

At present, the system used in series by multiple cycloidal motors (see Figure 1) is applied to sweepers, trenchless drills and airport luggage carts. The output shaft of the hydraulic motor often leaks oil during use, so it is useless to replace the dynamic seal of the output shaft. In series application, the problem of casing oil leakage pressure is ignored. The oil leakage pressure of the housing refers to the maximum pressure that the motor shaft seal can bear after the hydraulic motor is fully lubricated inside; If the hydraulic motor is applied want to buy High torque cycloidal hydraulic motor Improper. After the machine has been working continuously for a period of time, due to various factors, the oil in the housing will not be released, resulting in higher and higher pressure in the housing of the hydraulic motor, which first leads to the failure of the shaft seal. The casing leakage pressure mentioned here is not the bursting pressure of the casing, but the pressure that the motor output shaft dynamic seal can bear. In the motor samples of some manufacturers, only the back pressure is mentioned. Actually, back pressure refers to electricity High torque cycloidal hydraulic motor Price The return oil pressure of the engine, not the oil discharge pressure of the casing. During operation, the requirements for the oil discharge pressure of the cycloidal motor housing are as follows. Eaton is the world's first cycloid motor manufacturer. In China's domestic cycloidal motor manufacturing industry, Jining Jinjia Hydraulic Co., Ltd. uses Eaton technology to produce cycloidal motors. Its output shaft dynamic seal has better bearing capacity, that is, the unique internal oil circuit design of the company's products enables internal oil drainage not only to lubricate parts, but also to discharge excess oil while maintaining a certain housing oil drainage pressure.

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 Fushun High torque cycloidal hydraulic 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 want to buy High torque cycloidal hydraulic motor Large emissions, relatively small impact of leakage, large rotation inertia of the motor itself, easy to obtain good low-speed stability.

Cycloidal hydraulic motor structure: the internal meshing gear pair consisting of rotor and stator, cycloidal needle wheel, as the meshing pair, has a torque generating part. The stator, together with the spacer and the rear cover, is fixed on the housing to form seven cavities that are only connected with the oil holes on the housing one by one. A distribution mechanism consisting of an oil distribution sleeve and a housing. Two oil distribution sleeves Fushun High torque cycloidal hydraulic motor The ring groove is respectively connected with the oil inlet and return ports of the housing, and its longitudinal groove has twelve oil ports, High torque cycloidal hydraulic motor Price Six oil ports and the oil distribution hole of the housing form the oil distribution link. The splines at both ends of the linkage shaft are respectively connected with the rotor and the output shaft, which is used to transmit torque and ensure that the oil sleeve is synchronized with the output shaft. The function of the output shaft is to output the torque generated by the rotor through the linkage shaft and drive the oil distribution device to rotate synchronously.

The hydraulic motor is usually put into operation Fushun want to buy Clean before use. The purpose of cleaning is to remove the pollutants, metal chips, fiber compounds and iron cores left in Madai. In the first two hours of operation, even if the motor is not completely damaged, there will be a series of failures. Therefore, the hydraulic motor oil circuit should be cleaned as follows: 1. Clean the oil tank with easy drying cleaning solvent, and then remove the solvent residue with filtered air. 2. Clean all pipes of hydraulic motor. In some cases, it may be necessary to impregnate pipes and joints. 3. Install an oil filter on the pipeline to protect the oil supply pipeline and pressure pipeline of the valve. four want to buy High torque cycloidal hydraulic motor Install a flushing plate on the collector to replace precision valves, such as electro-hydraulic servo valve. 5. Check whether all pipes are of proper size and connected correctly.

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 High torque cycloidal hydraulic motor Price → 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 want to buy High torque cycloidal hydraulic motor The rotor is driven by 42 pressure oil with the maximum volume for 6 revolutions, so the motor has a large emissions.
