PROBLEM TO BE SOLVED: To secure air-tightness in a housing by a simple means without using a mechanical seal in a biaxial continuous kneader. SOLUTION: In the kneader 1, a magnetic coupling mechanism is formed between a mechanism in the housing 2 including shafts 3 and a carrier 5 disposed outside the housing 2. The magnetic coupling mechanism includes gear parts 3c provided in the shafts 3, a ring gear 4 rotatably supported in the housing 2 and at the outer peripheries of shaft ends of both shafts 3, and the carrier 5 rotatably supported outside the housing and coaxial with the ring gear 4. When the carrier 5 is driven, the ring gear 4 is rotated by magnetic action of magnet parts 4b, 5b, and the shafts 3 rotate by engagement of gear parts 3c, 4a. The inside of the housing can be sealed, thereby securing air-tightness. COPYRIGHT: (C)2012,JPO&INPIT |
