PURPOSE: A drilling device for an aircraft duct is provided to process a work without deformation of a motor shaft by installing a bearing unit in a motor unit. CONSTITUTION: A drilling device for an aircraft duct comprises a housing(1010), an inner cylindrical bucket, a motor unit(1100) for a drill, a camera unit(1300), and an outer driving unit(1500). A driven gear(1012) is formed on the rear surface of the housing. The inner cylindrical bucket is formed inside the housing and rotates according to rotation of the driven gear by being combined with the driven gear. The inner cylindrical bucket rotates around the center of the housing. The motor unit(1100) for the drill and the camera unit are formed inside the inner cylindrical bucket. The motor unit(1100) for the drill and the camera unit rotate around the center of the housing as the driven gear rotates. The outer driving unit includes a driving gear(1502) engaged with the driven gear. |
