摘要:
Bei einem Schwenkmotor mit Flüssigkeitsantrieb ist die Nelle (6) in dem Motorgehäuse (1), das mit einem diese kontentrisch umgebenden ringförmigen Raum (18) versehen ist, gelagert. Der Raum (18) ist durch zwei Flügel (19, 20) in zwei Um den Herstellungsaufwand gering zu halten und eine gute Abdichtung des Motors zu schaffen, trägt die Welle (6) eine radiale Scheibe (13), die mit einer diese konzentrisch umgebenden, im Querschnitt halbkreisförmigen Nut (15) versehen ist. Die Scheibe (13) liegt mit ihrer mit der Nut (15) versehenen ebenen Stirnfläche plan auf einer radialen ebenen Bodenfläche des Gehäuses (2) auf, die eine entsprechende umlaufende, im Querschnitt halbkreisförmige Nut (16) aufweist, die mit der Nut (15) der Scheibe (13) einen mittig geteilten torusförmigen Ringraum (18) bildet. In der Nut (15) der Scheibe sowie in der gehäuseseitigen Nut (16) sind je ein torusektorförmiger Flügel (19,20), dessen kreisförmiger Querschnitt einen Radius aufweist, der dem Radius der Nuten (15, 16) entspricht, befestigt. Eine gute Abdichtung wird dadurch erreicht, daß die an die ringförmigen Nuten (15, 16) angrenzenden ebenen Flächen der Scheibe (13) und des Gehäuses (1) dichtend gegeneinander gepreßt werden.

A bearing arrangement for a unit that is mutually turnable around a centre of rotation (R) comprising an external part (1) and an internal part (7), which, with the aid of high hydraulically acting pressure, is arranged to achieve a reciprocating rotary motion, or that is arranged to achieve a high hydraulic pressure from an applied torque from a reciprocating motion, whereby the external part (1) is provided with side walls arranged to axially surround at least a part of the internal part (7), and whereby the external part (1) comprises a radially inwardly arranged and essentially surrounding cavity (11, 12, 13, 14) in which the internal part (7) is arranged such that it can be rotated, which cavity (11, 12, 13, 14) is limited in the circumferential direction by at least one wing (3, 4) that protrudes inwards from the external part (1) and also limited by at least one wing (9, 10) that protrudes radially outwards from the internal part (7), which wings (3, 4, 9, 10) limit at least two chambers or compartments (11, 12, 13, 14) between the external part (1) and the internal part (7). At least one of the side walls of the external part is fixed connected with the, at least one, wing (3, 4) that protrudes radially inwards towards the internal part (7), which wing demonstrates a surface that faces radially inwards and that has a circular concave curvature for connection with an outwardly facing circular convex contact surface (8) at the internal part (7).

The sealing system for oscillating-piston engines, comprising at least two oscillating pistons (15) which revolve together in a spherical housing (24) about an axis (45) of revolution provided in the housing centre and which each have two opposite piston arms, which, when revolving, perform reciprocating oscillating movements in opposite directions about an oscillation axis (46) perpendicular to the axis (45) of revolution, wherein guide members (47) are provided on at least two pistons, said guide members (47) engaging in at least one guide groove (39) formed in the housing (24) for controlling the oscillating movements, has sealing elements (1, 2, 12, 14, 26, 33) on or in the vicinity of all moving edges surrounding the working chambers (17) and prechambers (30), which sealing elements (1, 2, 12, 14, 26, 33) close in a sealing manner all the gap regions present between machine parts displaced relative to one another by revolving and/or oscillating movements and not in direct contact, and has additional sealing elements (60) which prevent the excessive penetration of lubricating fluid into inlet (40) and outlet openings (41) in the housing (24).
摘要:
Disclosed herein is an oscillating vane type pump actuator. The pump actuator of the present invention provides a method of preventing fretting corrosion from being caused on joined surfaces of elements. A cylinder (3c) has a comparatively low radial strength, and each of side covers (1c) and (2c) has a high radial strength. A cylindrical portion (1c-c), (2c-c) is provided on each side cover. Thus, when high pressure of work oil distorts the cylinder into a shape in which the cross-section of the cylinder becomes an ellipse-like shape, the cylindrical portions of the side covers act such that they are distorted in the same shape as that of the cylinder. Further, a passage that always communicates with a low-pressure side working chamber is formed in the contact surfaces between a fixed vane that is fixed to the cylinder and the side covers.
