Abstract

PURPOSE: To strengthen the water sealing device of a main shaft enough to keep the displacement of the inner circular portion of a shelf plate within the circuit and to make its adequate sealing effect exhibited, by fastening shelf plate divided into the plural number of piece with bolts which are arranged in the neighborhood of the thick plate center of the innermost circular portion of the plates.
CONSTITUTION: A stud 12 is fixed in the neighborhood of the thick plate center of the inner circumference of the divided surface of the one side of a divided shelf plate 8, and a nut 14 fastening the stud 12 is housed. In a hole 13 drilled in the neighborhood of the divided surface of the opposite side. Thereby, as it becomes possible to fasten the divided pieces each other along the circumference in the neighborhood of the innermost circular portion of the shelf plate 8, the shelf plates 8 are regarded as a hollow disk subjected to an equally distributed load and supported freely with bolts 7. Accordingly, even in the case of a machine with its considerably large forced water head, a packing will not inline, and an adequate sealing effect mau be well exhibited.
