Abstract
PURPOSE: To improve the sealing capability by a method wherein an axial sealing cylindrical body and a shaft are fitted through a screw shaped uneven surface of a fitted surface, and oil drops, etc. are pressed into the fitted surface positively.
CONSTITUTION: An axially sealing cylindrical body 5 is arranged inside a stuffing box 4, and a screw shaped unevenness 7 is mounted to an inner surface opposing to a shaft 3. The screw shaped unevenness 7 functions as the extrusion of a fluid to the outside A of the device. A bevelled section 5A introducing oil mists into axial sealing space is installed to an end surface at the outside of the device of the axially cylindrical body 5. The oil mists supplied to a bearing 2 from a lubricating passage 9 enter a clearance between the shaft 3 and the axial sealing cylindrical body 5 from the bevelled section 5A. Thus, the concentration of the oil mists in sealing space increases, and the transfer force of the fluid by means of the screw shaped unevenness 7 is augmented.
