Rotary drilling A6VM160HD1D/63W-VAB010 power head motor; generally speaking, hydraulic motor reducer have two to three sets, respectively connected to the reducer through the output shaft of the reducer and reduce the pinion in the power box, and the same gear ring external mesh, gear ring and drill pipe drive sleeve through the positioning pin and bolt fixed as a single unit, to achieve the function of rotary transmission. The drive is a multi-stage sealed closed box, which requires heavy duty gear oil for lubrication
There is a ventilation hole in the upper part of the reducer, the purpose of which is to ensure the balance of pressure inside and outside the reducer during operation, so it is necessary to ensure that the ventilation hole of the reducer is free and clear, and do not set up obstacles around it. When the surrounding environment is sandy and dusty, it should be covered with a screen or replaced with a better air filter. When the vent hole is blocked and not smooth, the internal pressure of the reducer increases, and the lubricant will leak from the oil seal at the input or output end, resulting in a drop in oil level and pollution of the surrounding environment.
Reducer in the work, the output torque is large, and in the shock, vibration environment, the reducer connection bolts and reducer and peripheral system connection bolts are easy to loosen. Therefore, you should check the tightness of the connecting bolts in time (the connecting bolts should be added with elastic pads or take other reliable anti-loosening measures).
