Abstract (en)
The housing has a horizontal joint, upper inner housing parts (10, 11) formed above the horizontal joint, and another two inner housing parts (6, 7) formed below the horizontal joint. The inner housing parts formed below the horizontal joint are formed by a vertical joint, and the inner housing part formed above the horizontal joint exhibits another vertical joint. The housing parts are formed from a nickel-base-material. The inner housing parts are divided in circumferential direction (9) with respect to a rotation axis. An independent claim is also included for a method for manufacturing an inner housing.
