Speed Regulating Type Hydraulic Coupling Reverse Gear Box Yotfj750/875

Company Profile

Our Advantages

1. Easy installation, diesel engine coupling unit and drilling pump can be respectively integrated lifting.

2. Compared with the traditional single pump group configuration, the belt transmission is cancelled, avoiding the malady of adjusting belt string tightness due to belt stretching.

3. With clutch function. When the diesel engine does not stop, and at any speed, through the coupling of oil filling and oil discharge, can be without any impact and wear, smooth clutch, can replace the air bag clutch, simplify the transmission parts.

4. Prevent power overload. When the output shaft torque increases suddenly, the coupling slip will increase by itself, thus protecting the diesel engine, mud pump and coupling back case from damage.

5. Reliable operation, long service life coupler is a kind of flexible transmission device with mineral oil as the medium, no impact and wear in the operation and clutch process, but also can absorb vibration from diesel engine and mud pump. Therefore, its operation reliability and life are obviously higher than that of mechanical transmission without coupling. The life of diesel engine and transmission system can be increased by 40 ~ 60%, and the amplitude of pump pressure pulsation of mud pump can be reduced by 50%.

6. Bearing gear adopts forced splash lubrication. An oil passage is designed on the box body to lubricate and cool the end face of the gear and the bearing to ensure their normal operation.

7. Oil pressure taper interference fit is used to connect the turboshaft, output shaft and the inner hole of the gear system of the reverse gearbox. Its characteristics are: large transmission torque, long service life, safe and reliable.

8. The shaft ends of the input shaft and output shaft adopt non-contact centrifugal seal, never wear, with a long service life.
