Abstract

PURPOSE: To extend the life of the packing and to obtain excellent sealing characteristics by press-welding a multi number of packing pieces with fine clearances with each other in the peripheral direction on the rotary shaft by the packing gland and the garter spring.
CONSTITUTION: The sealing surfaces 11c of the packing pieces 111W11n arranged in circle around the main shaft 1 is pressure-welded on the outer surface of the main shaft 1 through the packing gland 6 by the spring force of the garter spring 7. Initially, the packing pieces 111W11n keep the fine clearances g in the peripheral direction, but the clearances g gradually become smaller as the sealing surface 11c is worn away, until there are no clearances g. From then on, the packing pieces 111W11n do not shift. As the packing pieces 111W11n are thus constituted so that the fine clearances are gradually decreased, the life of the packing can be extended and the sealing characteristics can be maintained for a long time.
