Abstract

PURPOSE: To prevent the entry of water and powdery dust into a revolving chamber, by a method wherein a toroidal sliding plate is mounted on a frame of a lower running object, and a seal ring, installed at a under surface of a frame of an upper revolving object, is pressed against said sliding plate.
CONSTITUTION: A partition 19, partitioning a revolving gear chamber 16, is positioned at a lower turning object 3, and a toroidal sliding plate 23 is placed on an upper plate 22 of the partition plate at the upper end of the partition plate 19 through the medium of a knock pin 24. Meanwhile, a toroidal recess 25 is formed in a frame 1a of an upper revolving object 1, a seal ring 26 is inserted into said recess 25, and is pressed against said sliding plate 23 by means of a toroidal plate spring 33. Seal parts 29 and 30 in the seal ring 26 are filled with greases 31 and 33. So constituted seal enables preventing of the entry of water and powdery dust into the revolving gear chamber 16.
