STRUCTURE FOR FITTING AND SUPPORTING KILN TIRE

摘要

PROBLEM TO BE SOLVED: To reduce the abrasion of washers and a tire, to prevent a shell from having ovality and to lessen the impairment of lining bricks by making it possible to follow the thermal expansion of the shell without causing a thermal stress and to support the shell to rotate by the tire without leaving no space between them, while keeping the shell in a state of a perfect circle. ;SOLUTION: This structure has a plurality of main washers 12 which are fitted to a shell 1a of a kiln, spaced from each other in the circumferential direction, and are urged outward radially, a plurality of auxiliary washers 14 which are fitted to the shell 1a at the circumferential middle positions of the adjacent main washers 12 and urged inward radially and a plurality of connecting washers 16 which are fitted movably in the circumferential direction between the main washers 12 and the auxiliary washers 14. The main washers 12 and the auxiliary washers 14 have respectively taper surfaces 12a and 14a narrowing inward radially, at the opposite ends in the circumferential direction, while the connecting washers 16 have taper surfaces 16a and 16b widening inward radially and sliding on the taper surfaces 12a and 14a mutually, at the opposite ends in the circumferential direction.;COPYRIGHT: (C)2000,JPO
