The present invention relates to a drilling device. Said device can be installed on drilling machine or CNC machine for achieving the purpose for drilling an inner hole. The said drilling device includes a base. Two notches are installed on the axial of said base. A screw is passed through one of said notches. According to said device, said base can be installed on drilling machine or CNC machine for achieving the purpose for drilling an inner hole. In addition, an oil passage is installed on the bottom of said base. Said oil passage is connected with driving gear. Thus, when drive gear drives gears to be rotated, the lubricant oil can be transported to each gear for achieving the purpose of lubrication.
Drive assembly, for underground mining equipment, has a gearing and an overload clutch with a common oil sump for the gear lubrication circuit and the clutch switch circuit
