with Blast Hole Coupling and High Speed Water Swivel .
The chuck is accurately machined to assure perfect alignment. The jaws are held by two large, Allen set screws with countersunk heads in chuck body to make it impossible for them to catch the operator’s clothing while rotating. Successive pairs of. .
Exploded view showing method of jacking rear end plate out of motor housing for changing rotor blades .
The reversible air motor greatly speeds blast hole drilling by allowing rapid unscrewing of rod joints, after breaking joint with a wrench, and allowing for rapidly moving the chuck or blast hole coupling into drilling position. High bit speeds available where. .
The motor consists of a cylinder in which a rotor is mounted eccentrically, six slots in the rotor hold six laminated, phenolic blades which move in and out against the cylinder wall as the rotor revolves. These blades and the rotor are the only rotating parts. Ball bearings,.

To optimize and improve the impact performance of a hydraulic rock drill, it is helpful to test the stress waves of the drill and analyze the impact energy, impact frequency, and energy utilization rate. For this study, a stress wave test bench was designed and built, according to international. .
Percussion drilling is believed to be an efficient way to enhance the drilling performance, compared with the conventional drilling in deep wells, which could be achieved by applying impact loads above the drill bit. The finite simulation is an efficient method to predict the drilling performance.
