PURPOSE:To perform precise centering control of a casing by projecting supporting arms from the upper half part of an inner casing and aligning arms from the lower half part thereof so as to fit with each other up and down at both left and right sides of the inner casing. CONSTITUTION:Supporting arms 23 and aligning arms 24 are projected from the forward and rear parts of the inner casing 2 to the left and right sides so as to overlap up and down each other. A jack bolt 5 is screwed in a clearance hole 27 to force the inner casing 2 upwards to a slight extent thereby allowing easy insert of a liner 3. Centering control of a casing through a range from large scale machines to small ones may be thereby precisely performed. |
