粉砕ローラの製造方法及び昇温装置

Japanese Patent JP7102270

B2

This method is for manufacturing a grinding roller that is provided with: a journal housing that is rotatably supported with respect to the housing of a grinder; and an annular roller (24) that has an annular base (25) and a hardened part (26), which is provided on the outer circumferential surface of the base (25) and has a smaller coefficient of thermal expansion than the base (25). This method for manufacturing the grinding roller comprises: a heating step for heating the roller (24) from the outer circumferential surface with the roller (24) disposed so that the central axis line (C1) thereof is orthogonal to the floor and the inner circumferential surface is open to outside air; a placement step for placing the journal housing and the roller (24), the temperature of which has been raised by the heating step, so that the inner circumferential surface of the roller (24) and the outer circumferential surface of the journal housing face or contact each other; and a fitting step for cooling the roller (24), which has been placed in the placement step, and fitting the journal housing together with the roller (24).
