The advantage of hydraulic slew drive

Hydraulic slew drive is safe and reliable in braking, good stability and high transmission efficiency. It is widely used in the transmission mechanism of construction engineering, oil field drilling and production machinery. Why do you like to use hydraulic slewing drive ? This is inseparable from its characteristics, what are the specific advantages? This article will tell you.

1.What is hydraulic slewing drive?            

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. The hydraulic slew drive is composed of planetary reducer with various valve groups and can also be driven by transmission gear.

2.Advantages of hydraulic slew drive            

The hydraulic slew drive has the characteristics of small radial size, safe and reliable braking, bidirectional rotation, large radial and axial external force, high starting efficiency, good stability at low speed, high transmission efficiency, low noise and good economy. hydraulic slewing drive can transmit large power and output large force or torque. In the case of transmitting the same power, the hydraulic slew drive has the advantages of small volume, light weight and compact structure.            

Because of its light weight, small inertia, stable operation and small reversing impact, the hydraulic device is easy to realize quick start, braking and high frequency reversing. The number of times per minute of rotary motion is incomparable with other transmission control methods.   

The hydraulic slew drive is easier to realize linear motion than mechanical device, and can realize stepless speed regulation in the process of movement. The speed regulation range is large (the speed regulation ratio can reach 1:2000). The speed adjustment is easy, and the speed regulation performance is good. It can realize overload protection and realize self lubrication, so it has a long service life. The hydraulic slew drive is easy to adjust and operate, and it is easy to realize automation. If combined with electrical control, it can realize sequential action and remote control conveniently. Hydraulic components have been standardized, serialized and generalized, which is convenient for design, manufacture and popularization.

3.Hydraulic slew drive advantages over Mechatronics            

It can realize a wide range of stepless speed regulation in the process of operation. Under the same output power, the hydraulic slewing drive has small volume, light weight, fast reaction speed, can realize seamless transmission, stable movement, and is convenient to realize automatic working cycle and automatic overload protection. Because oil is generally used as transmission medium, which has lubrication effect on hydraulic components, it has a long service life The original parts are standardized series products, which can be purchased directly from the market, which is conducive to the design, manufacture and application of hydraulic system. Large thrust hydraulic cylinder or high torque hydraulic pump can be used to directly drive the load, thus eliminating the intermediate deceleration device and simplifying the transmission.

4.Application scope of hydraulic slew drive            

It can be widely used in the hydraulic slew drive of the coal mine, the hydraulic slew drive can be widely used in the oil field, the hydraulic slewing drive, etc.

Of course, in addition to the above advantages, hydraulic slew drive also has some disadvantages, for example, it is more sensitive to the change of oil temperature, and it is not suitable to work under very high or low temperature conditions. Due to more advantages, it has become the choice of more and more people.
