What is hydraulic slew drive？

Hydraulic slew drive device is composed of hydraulic motor, reducer, gear end and other structures, which can make the production efficiency become higher and the range of use is constantly improved. The hydraulic slew drive device is easy to install and maintain, and has many advantages, which is loved by more and more people. What is the hydraulic slewing drive device? This article gives you a comprehensive explanation.

1.Concept of hydraulic slew drive device            

Hydraulic slew drive device is composed of hydraulic motor, brake, reducer, valve group and gear end structure. It is modular design. It is transmitted to gearbox through hydraulic motor to increase torque and reduce speed, so as to realize the requirement of low speed and high torque. Due to the high integration of hydraulic slew drive device, the user does not have to purchase and process each part of the rotary device one by one. To a certain extent, it also reduces the preparation process at the beginning of production, thus greatly improving the labor productivity.

2.How to distinguish the model of hydraulic slewing drive device?

Hydraulic actuator is one of the five basic components of hydraulic system. Hydraulic actuator (hydraulic actuator) refers to the device that converts hydraulic energy into mechanical energy, so as to realize reciprocating linear motion or swing of actuator and output force or torque. Hydraulic actuator can be divided into hydraulic motor and hydraulic cylinder.

Wk hydraulic slew drive is allowed to work under high back pressure. In continuous operation, the back pressure is 10MPa. The maximum allowable pressure of shell is 0.3MPa. If you have special requirements, please contact the manufacturer. Hydraulic oil: it is recommended to use high quality, anti foam and anti oxidation mineral based hydraulic oil. The ideal working oil temperature is 30 -50 C, and the oil temperature is -20 to 80 C. When the oil temperature is below 10 C, the low pour point hydraulic oil must be used. The viscosity of the hydraulic oil is 40~60 centigrade, and the allowable rate is 5~300 centigrade. The filtering accuracy of the liquid oil is recommended as 25um or higher filtration precision. The hydraulic transmission device can rotate in both directions.

Oil drain pipe positioning: wk hydraulic slewing drive device is allowed to be installed in any direction: in order to ensure the lubrication of the moving pairs in the motor, it is required to fill the madar with hydraulic oil before operation, and the location of oil drain port must ensure that the shell is full of hydraulic oil during operation. Oil inlet and outlet direction of distributor: the oil inlet and outlet direction of the distributor is allowed to rotate at 72 ° interval according to the contour installation connection position, but the sealing function of plane O-ring cannot be damaged when the screw is loosened and rotated.

Hydraulic slew drive device can be used in any situation that requires full circle rotation and speed change requirements. It has the advantages of simple structure, convenient manufacturing and maintenance, and strong practicability. It is widely used in aerial vehicles, photovoltaic power generation, wind power generation and engineering machinery claw.
