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 special-purpose Sweeper 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 Sweeper cycloidal hydraulic motor Manufacturer 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 device that can be converted into rotary motion is called motor. The hydraulic motor is a device that can convert the pressure energy of liquid medium into rotary motion. It converts the hydraulic energy provided by the hydraulic pump into mechanical energy. At the same power output, the weight and size of the hydraulic motor is only 5% - 20% of that of the DC motor, and the relative weight is very light, so the moment of inertia is small, the starting, braking and reversing are fast, the low speed stability is good, and the inorganic speed regulation can be easily realized. how special-purpose Sweeper cycloidal hydraulic motor Select the hydraulic motor suitable for yourself: the main parameters of the hydraulic motor include pressure, flow, displacement and output power; The choice of the ideal hydraulic motor mainly depends on your desired power and Mount Huangshan Manufacturer The hydraulic pump you are using now matches. You can also see the selection of displacement. The displacement V is obtained by dividing the system flow Q by the required motor speed n. Select the model according to the displacement and check the prototype to see whether the motor torque meets the requirements.

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 Sweeper cycloidal hydraulic motor Manufacturer 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 special-purpose Sweeper 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.

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 Mount Huangshan Manufacturer 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 Sweeper cycloidal hydraulic motor Manufacturer With the running torque, the drum reduces friction and improves efficiency. The low speed output shaft can also produce stable output.

Actuator: hydraulic cylinder, hydraulic motor and swing hydraulic motor. Function: convert the pressure energy of liquid into mechanical energy, which is used to drive the working mechanism to do work and realize reciprocating straight special-purpose Sweeper cycloidal hydraulic motor Linear motion, continuous rotation or swing; Governor: pressure, flow, direction control valve and other control elements. Function: control the oil pressure, flow and direction from the pump to the actuator in the hydraulic system, so as to control the force (torque) and speed output by the actuator Mount Huangshan Sweeper cycloidal hydraulic motor Degree (speed) and direction, to ensure that the main engine working mechanism driven by the actuator can complete the predetermined motion law; Hydraulic auxiliary device: oil tank, pipe fittings, filter, heat exchanger, accumulator, indicating instrument, etc.

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 Sweeper cycloidal hydraulic 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 Sweeper 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.
