摘要:
Die Erfindung geht aus von einem Elastomerinnenmischer mit einer Mischkammer, einem oder zwei hierin befindlichen Rotoren mit die Wandung des Gehäuses durchsetzenden Wellen und mit einer oben gelegenen, verschliessbaren Einfüllöffnung für das Mischgut und einem unten gelegenen Sattel an der Austrittsöffnung, wobei dem Mischer Anschlüsse an eine Sauglufteinrichtung zur Beeinflussung der Druckes innerhalb der Mischkammer zugeordnet sind. Um mit einfachen Mitteln grosse Unterdrücke in der Mischkammer erreichen zu können, sind aufgrund der Erfindung die aussen gelegenen Wanddurchbrüche für die Wellen von einer praktisch luftdichten Wandung umschlossen, die einen oder mehrere Anschlüsse für die Sauglufteinrichtung aufweisen.
摘要:
The relative displacement in the axial direction between an outer ring fixing member (17) or casing (18) and an inner ring fixing member (20) or rotor (5) is determined, said outer ring fixing member (17) being a member for affixing an outer ring (16) of a bearing (6) on one side, and said inner ring fixing member (20) being a member for affixing an inner ring (13) of the bearing (6) on the one end side. When calculating a thrust load acting on the rotor (5) by multiplying the determined relative displacement by a conversion coefficient, an axial force measuring bolt (26) is used as a tightening bolt for affixing the bearing (6) on the one end side, said axial force measuring bolt (26) enabling measurement of a load acting in the axial direction. The axial force measured by the axial force measuring bolt (26) and the relative displacement during measurement of the axial force are used to calibrate the conversion coefficient.

The invention provides a method for producing a fluororubber composition that is able to give a crosslinked article that exhibits not only heat resistance, but also excellent mechanical properties at high temperatures. A method for producing a fluororubber composition includes: a step (1-1) of mixing a fluororubber (A) and a carbon black (B) by means of an internal mixer until the maximum temperature reaches 80 to 220°C so as to obtain an intermediate composition; a step (1-2) of cooling the intermediate composition to a temperature of less than 50°C; and a step (2-1) of mixing the cooled intermediate composition until the maximum temperature reaches not lower than 10°C but lower than 80°C so as to obtain a fluororubber composition.

The invention relates to a kneader for carrying out mechanical, chemical and/or thermal processes, comprising at least two shafts (5, 6), which rotate in a manner that is parallel to the axis and which are situated inside a housing having an inner wall (31). Kneading bars (24), which follow one another in a direction of rotation and in an axial direction of the shafts (5, 6) and which extend along the inner wall (31) of the housing and in the direction of the shafts (5, 6) or diagonal thereto, are located on said shafts (5, 6) while being mounted on a supporting element (22.1, 22.2, 23.1, 23.2). The paths of the kneading bars (24) on both shafts (5, 6) overlap at least partially and, during rotation, the kneading bars (24) on one shaft engage between the supporting elements (22.1, 22.2, 23.1, 23.2) on the other shaft. To this end, supporting elements (22.1, 22.2 or 23.1, 23.2) of different thicknesses are arranged in succession and in a direction of rotation (X) on the shaft (5, 6) while being situated on and/or in a radial plane (E).
