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 Low speed 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 Low speed cycloidal hydraulic motor manufactor 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.
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.
If the hydraulic system is compared to the human body, then the hydraulic oil is equal to human blood. In the hydraulic system, the hydraulic oil plays a role in energy transmission, system lubrication, and prevention Jilin Low speed cycloidal hydraulic motor The functions of corrosion, rust prevention and cooling, and whether the hydraulic system can work effectively are closely related to the type and selection of hydraulic oil. Coding, composition and characteristics of hydraulic system: high purity general machine tool oil, refined mineral lubricating oil, with good rust resistance and oxidation resistance. High wear resistant hydraulic oil, refined mineral lubricating oil, rust proof, anti-oxidation, anti-wear. High temperature and high pressure hydraulic oil, with the characteristics of rust prevention, oxidation resistance, wear resistance, etc., is refined into mining lubricating oil, and added with viscosifier. Refined mining lubricating oil HG hydraulic guide oil, rust proof, anti-oxidation, anti-wear, anti stick slip. HS synthesis want to buy Low speed cycloidal hydraulic motor Hydrocarbon is a kind of low temperature hydraulic oil, which has the characteristics of anti-oxidation and anti-wear.
In the late 1850s, the original low-speed high torque hydraulic motor was developed from the fixed rotor part of the oil pump, which consists of an internal gear ring and matching teeth Jilin manufactor Wheel or rotor. The inner gear ring is fixedly connected with the housing, and the oil entering from the oil port pushes the rotor to rotate around the center point. This slowly rotating rotor is driven and output by a spline shaft to become a cycloidal hydraulic motor. After the first cycloid motor came out, after decades of evolution, Jinjia hydraulic hydraulic motor delivers high efficiency energy for you. Another concept of motor also began to form. The motor installs the drum in the built-in ring gear. Motors with rollers can provide high starting Low speed cycloidal hydraulic motor manufactor With the running torque, the drum reduces friction and improves efficiency. The low speed output shaft can also produce stable output.
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 Low speed cycloidal hydraulic motor manufactor 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 Low speed 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.
