590 drilling rig lifting motor

The 590 crawler hydraulic drilling rig is a fully hydraulic drilling rig. The drilling rig's walking, turning, and lifting actions are executed through walking motors, turning motors, and propulsion motors. The commonly used models for propulsion and lifting motors are 6K-490 and similar models. The design characteristics of this motor are consistent with actual requirements.

590 drilling rig lifting motorThe main features are as follows:

1. Three section design, balance plate wear compensation design, all using fixed rotor components with needle teeth;

2. The motor integrated housing internal oil replenishment check valve is mainly suitable for working conditions with inertial loads;

3. The motors are designed with internal butterfly valves to maintain a housing pressure that is more than ten Bar higher than the return port pressure;

4. Two conical bearings are used for support, effectively ensuring lateral load capacity;

5. It can work in both forward and reverse directions without stopping the machine when reversing.

Additionally, we will focus on introducing Eaton motors

3. End face distribution type cycloidal hydraulic motor

4. *The parameter design of the embedded column fixed rotor has low starting pressure, high efficiency, and smooth low-speed operation

5. *The shaft seal design has a high ability to withstand back pressure

6. *Reliable linkage shaft design ensures long lifespan of the motor

7. *The design of the distribution mechanism has the characteristics of high distribution accuracy and automatic wear compensation

8. Motors are allowed to be used in series and parallel, and when used in series, an oil leakage pipe should be connected

9. Adopting a tapered roller bearing support design, it has a large radial bearing capacity, allowing the motor to directly drive the working mechanism

10. Multiple installation and connection forms for flanges, output shafts, oil ports, etc

13. Intermittent working pressure refers to the maximum allowable pressure at the inlet, while continuous working pressure refers to the working pressure difference.

14. It is not allowed to use the motor at both maximum speed and maximum pressure simultaneously.

15. Under intermittent working conditions, the motor's running time per minute shall not exceed 10%.

16. Recommended oil: anti-wear hydraulic oil, viscosity 37~73cSt, oil cleanliness ISO18/13.

17. The maximum working oil temperature is 80 ° C.

18. This series of motors adopts special imported shaft sealing components, and the maximum allowable back pressure of the motor can reach 7 MPa, but in order to achieve good service life.
