摘要:
Displacement sensors (19) are configured so as to be capable of measuring relative displacement along the axial direction of an outer ring-fixing member (17), which is for fixing the outer ring (16) of one end of a bearing (6), or a casing (18) with respect to an inner ring-fixing member (20), which is for fixing the inner ring (13) of the one end of the bearing (6), or the rotor (5). A load-calculating unit calculates the thrust load acting on the rotor (5) by multiplying the relative displacement measured by the displacement sensors (19) by a conversion coefficient.
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.

A kneading rotor, in which the length L4 of a long blade in the direction of rotation of a rotor section is greater than one half of the total length L5 of a rotor section main body in the direction of rotation, and the long blades are arranged in such a manner that, in a case where a pair of the rotor sections are arranged mutually in parallel inside the chamber of the closed kneading machine and are rotated in mutually opposite directions, an end section on the rearward side in the direction of rotation of the rotor section, of the long blade of one of the rotor sections, and an end section on the forward side in the direction of rotation of the rotor section, of the long blade of the other one of the rotor sections, alternately repeat mutually an approaching action and a separating action, and in the state of approach, the end section on the forward side and the end section on the rearward side oppose each other in the direction of rotation of the rotor sections on a line which links the respective central axes of the pair of rotor sections, in one cross-section perpendicular to the axial direction of the rotor section.

The invention relates to the processing, in a closed mixer (1), of polymer-based mixtures and compounds for the manufacture of tyres or components thereof. To improve the dispersion of the ingredients in the polymer base, the pressing ram (8) is lowered to the working condition controlling the position thereof over time, in order to compress the ingredients within the mixing chamber (4). The invention is particularly suitable for the dispersion of reinforcing fillers such as silica or carbon black in the polymer base and the incorporation of said fillers in the latter.

Innenmischer zur Verarbeitung von Kautschuk- oder kautschukähnlichen Kunststoffmischungen,
mit einer von einem Kammergehäuse begrenzten Mischkammer, mit zwei in der Mischkammer im wesentlichen parallel zueinander ausgerichteten Rotorwellen, mit einer im Kammergehäuse im wesentlichen oberhalb mittig zwischen den Rotorwellen ausgebildeten Einfüllöffnung (5), mit in der Einfüllöffnung verschiebbar ausgebildetem Stempel (8) zum Öffnen und Schließen der Einfüllöffnung (5), mit unterhalb der Rotoren im wesentlichen mittig zwischen den Rotoren ausgebildeten zum Öffnen und Schließen des Kammergehäuses bewegbarem Auslaßsattel (17), wobei die Kontur (46) des Sattels in einer Schnittfläche im wesentlichen senkrecht zu den Drehachsen der Rotoren in Schließstellung des Sattels an der zur Kammer weisenden Stirnfläche des Sattels (17) derart ausgebildet ist, daß sie von den beiden Rändern der Stirnfläche zur Sattelmitte hin jeweils einen von der Kammer wegweisenden konkavern Verlauf einnimmt und an den Rändern der Stirnfläche einen Winkel β größer oder gleich 0° zur Verbindungsgeraden der beiden Ränder einschließt.
摘要:
An internal mixer is of the type which comprises a mixing chamber (11) having one or more mixing rotors (12), and a floating weight (15) which is movable between an upper lifted position when charging material into the mixing chamber and a lower pressing position for applying pressure to material in the mixing chamber during a mixing stage. In accordance with the invention, the lift means (23-25) for lifting the floating weight (15) up to its lifted position is a fluid-operated piston-cylinder mechanism (23-25) in which the cylinder (25) is formed internally of the floating weight.
摘要:
Innenmischer mit symmetrisch um den Füllschacht (2) herum angeordneten Hydraulikzylindern (31 bis 34). Der Stempel (20) wird über ein bewegbares Querhaupt (22) und eine Stempelstange (21) angetrieben. Es wird eine niedrige Bauweise des Innenmischers erzielt. In der Mischbetriebsstellung des Stempels (20) stehen die oberen Kolbenräume (41) mit einem ersten Druckspeicher (64) und die unteren Kolbenräume (42) mit einem zweiten Druckspeicher (78) in Verbindung, so daß die hydraulische Betätigungseinrichtung (30) eine federnde Einspannung der Kolben (40) und damit des Stempels (20) bewirkt, der deshalb in der Mischbetriebsstellung gegenüber dem Mischgut federnd zurückweichen kann.
