Abstract
This rotor for kneading includes a rotor shaft (27) having a tubular shape; a blade part (22) that is provided on an outer peripheral surface of the rotor shaft (27); and a filling body (36) that is provided in a recessed part (28) formed inside the blade part (22) and made from a material having a higher thermal conductivity than a material from which the rotor shaft (27) and the blade part (22) are made.
Claims5
A rotor for kneading comprising:
- a rotor shaft having a tubular shape;
- a blade part that is provided on an outer peripheral surface of the rotor shaft;
- and
- a filling body that is provided in a recessed part formed inside the blade part and made from a material having a higher thermal conductivity than a material from which the rotor shaft and the blade part are made.
A method for manufacturing a rotor for kneading having a rotor shaft that is tubular and has a blade part for kneading provided on an outer peripheral surface thereof, the method comprising:
- a filling body forming step of forming a member made from a material, which has a higher thermal conductivity than the material of the rotor shaft and the blade part, in a predetermined shape;
- a filling body arranging step of arranging the filling body formed in the filling body forming step, inside a mold of the rotor shaft, at a position located further toward a radial inner side of the rotor shaft than an outer peripheral surface of the blade part, at a position where the blade part of the rotor shaft is provided;
- and
- an insert casting step of pouring the material of the rotor shaft into the mold in a state where the filling body is arranged in the filling body arranging step.
A method for manufacturing a rotor for kneading having a rotor shaft that is tubular and has a blade part for kneading provided on an outer peripheral surface thereof, the method comprising:
- a rotor shaft manufacturing step of manufacturing the rotor shaft such that a recessed part is formed in an inner peripheral surface of the rotor shaft at a position where the blade part is provided;
- and
- a filling step of filling a filling material made from a material having a higher thermal conductivity than the material of the rotor shaft and the blade part, into the recessed part from an outer peripheral side of the rotor shaft, to install the filling body.
