ASSEMBLING STRUCTURE BETWEEN INNER RACE OF BEARING AND JOURNAL, RACE AND JOURNAL SUITABLE FOR SUCH STRUCTURE, AND TURBO MACHINE EQUIPPED WITH THEM

摘要

PPROBLEM TO BE SOLVED: To provide an assembling structure between an inner race and a journal, which assembling structure does not cause conventional troubles. PSOLUTION: The assembling structure between the inner race 6 of a bearing and the journal 2 to be rotatably supported in the bearing comprises an annular groove 36 of the journal and an annular groove 26 of the inner race which grooves mutually operate so as to form an annular channel 52 when the bearing and the journal are arranged so as to face to each other, a stopper ring 40 which is arranged in the annular channel 52 so as to prevent a translational relative movement between the journal 2 and the inner race 6, and at least one recessed portion 38 of the journal 2 and at least one tooth 32 of the inner race 6, which recessed portion 38 and tooth 32 mutually operate so as to prevent a rotational relative movement between the journal 2 and the inner race 6.
