AUGER DRIVING DEVICE OF A DRILL CAPABLE OF ENHANCING THE LIFE OF A DRIVING DEVICE BY ABSORBING AN IMPACT TRANSFERRED FROM THE LEADING END OF A DRILL ROD

摘要

PURPOSE: An auger driving device of a drill is provided to enable a hydraulic generator to control torque and prevent a driving device from becoming damaged by an impact when boring is made.;CONSTITUTION: An auger driving device of a drill comprises a rotating shaft(100), a housing(110), a hydraulic motor(120), and an impact absorber(130). A rotating gear(102) is spline-coupled to the rotating shaft. The rotating gear is held in the housing, and the rotating shaft is coupled passing through the central part in the thickness direction. The hydraulic motor is formed on both sides of the upper surface of the housing and a pinion gear(126) is arranged on one end of the hydraulic motor. The pinion gear is meshed with the rotating gear. One end of the impact absorber is coupled to one end of the rotating shaft, and the drill rod is connected to the other end of the impact absorber.;COPYRIGHT KIPO 2012
