Abstract

PURPOSE:To simply repair and replace a rotor main body without losing both end support function by dividing the rotor main body and a drive shaft and driving the rotor main body by the drive shaft through a spline fitting part. CONSTITUTION:When a kneader is operated, torque is transmitted to a rotor main body 13 from a drive shaft 9 through a spline fitting part 14 to rotate the rotor main body 13 around on its axis. At this time, bending load is applied to the rotor main body 13 but received by the straight fitting parts 15, 16 on both sides of the spline fitting part 14. Therefore, a rotor 6 can be certainly supported by bearings 11, 12. When the rotor main body 13 is repaired and replaced, the connection of a cylinder main body 1 and a bearing box 4 due to a lock member 31 is released to separate the cylinder main body 1 and the bearing box 4. At this time, since the rotor main body 13 and the drive shaft 9 are divided, it is unnecessary to disassemble the bearing part of the bearing box 4 and the rotor can be simply replaced.

(Problems to be Solved by the Invention) In the case of the rotor 6 having the kneading blades 8 as described above, bending stress is generated in the rotor 6 during kneading. However, this bending load cannot be applied by contact between the rotor 6 and the inner wall of the cylinder body 1, and this is the fate of a two-screw kneader using this type of rotor 6.

After opening the kneading chamber 2 and completely exposing the rotor 6,
It is necessary to remove the bearing poncus 4, which is divided into two halves, while keeping the bearing 11 attached. Therefore, the work itself is very difficult and requires a high level of skill in centering the coupling 32 and the like.

(Means for Solving the Problems) In the present invention, a drive shaft 9 at one end of a rotor 6 arranged in parallel in a kneading chamber 2 of a cylinder body 1 is mounted on a bearing box 4 attached to a bearing box 4 attached to the cylinder body 1. In a two-shaft kneading machine in which the other end of the rotor 6 is rotatably supported on the cylinder body 1 side via a bearing 12, each rotor 6 is connected to the rotor body 13 and the drive shaft 9. A spline fitting portion 14 is provided on the opposite ends of the rotor body 13 and the drive shaft 9 and is spline fitted to each other.
and straight fitting portions 15 and 16 on both sides of the spline fitting portion 14 in the axial direction.

In addition, since there are straight fitting parts 15 and 16 on both sides of the spline fitting part 14 in the axial direction, even though the rotor body 13 and the drive shaft 9 are separated, the bending load applied to the rotor is absorbed by the straight fitting. Since the parts 15 and 16 can support and transmit the information, support at both ends of the rotor 6 can also be ensured.
