A shaft current collector for a shaft assembly has a shaft and a machine part surrounding the shaft. The shaft current collector has an electrically conductive ring for arrangement on the shaft so as to electrically contact the same. The ring has an engagement recess which is arranged so as to extend axially relative to the central axis of the ring. A blocking element can be secured on the machine part relative to the shaft. When the shaft current collector is in the installed state, the blocking element engages into the engagement recess of the ring such that, as the shaft rotates, a rotation of the ring is restricted by the blocking element while the ring is electrically conductively contacted by the blocking element. A shaft assembly may have such a shaft current collector.

A sealing device has a sensor system for condition monitoring. The sealing device includes a sealing ring with a dynamic sealing section for dynamically sealing abutment at a sealing surface of a machine part and a pretensioning ring for pretensioning the sealing section against the sealing surface having a first section and a second section. The second section can be deflected in a spring-elastic manner in an axial or radial direction relative to the central axis of the sealing device from a first position relative to the first section. The sensor system includes at least one measuring element arranged in the intermediate space on the pretensioning ring, which responds indirectly or directly to a deflection movement of the first section of the pretensioning ring. A sealing arrangement may have such a sealing device.

A rotary seal seals a high-pressure region from a low-pressure region and has an assembly sleeve made of a rubber elastic material and at least one pressure-activatable rotary seal element with a seal edge. When a specified differential pressure value is exceeded, the seal edge of the rotary seal element rests sealingly against the seal surface of a machine part, thereby directly displacing a support element elastically supported on the rubber elastic assembly sleeve. When the specified differential pressure value is undershot, the support element is moved rearwards axially in the direction of the high-pressure region such that the seal edge of the rotary seal element is moved backwards into the seal edge rest position in which the rotary seal element lies against the seal surface without contact surface pressure or substantially without contact surface pressure or is arranged at a distance from the seal surface.

Abrégé

The invention relates to a seal arrangement (10), comprising: a first machine part (12) and a second machine part (14), which are arranged spaced apart from each other, forming a sealing gap (18), and are movable relative to each other in a rotational manner about a movement axis (16); a radial shaft seal ring (20) for sealing a high pressure side H of the sealing gap (18), to which high pressure side pressure can be applied by means of a fluid, against a low pressure side (N) of the sealing gap, having a base section (22), which is arranged held on a sealing holding structure (24) of the first machine part (12) and having a sealing head (26), which can be deflected flexibly relative to the base section (22) in the axial direction and which contacts the sealing surface (30) of the second machine part (14) in a radial direction in a pre-tensioned and sealing manner. The sealing surface (30) has a first sealing surface section (30a) adjoining the high pressure side H and a second sealing surface section (30b) adjoining the low pressure side N, wherein the first sealing surface section (30a) extends away from the sealing holding structure (24) in the direction of the low pressure side (N) and, together with the movement axis (16), forms an acute angle α, wherein the sealing head (26) contacts the first sealing section (30a) when an operating pressure pw is applied to the high pressure side H, said operating pressure being smaller than a specified limit operating pressure value plimit, and wherein the second sealing surface section (30b) is arranged radially in the direction of the low pressure side N in the direction of the sealing holding structure (24) of the first machine part (12) and forms an axial stop (36) for the sealing head (26), which the sealing head (26) contacts in the axial direction, in a sealing manner, when an operating pressure pw is applied to the high pressure side H, said operating pressure being equal to or greater than the limit operating pressure value plimit.

Abrégé

The invention relates to a seal arrangement (10), comprising: – a first and a second machine part (12, 14) which are arranged spaced apart from one another, forming a sealing gap (18), and which are able to move relative to one another about a movement axis (16); – a seal element (20) having a root section (24) which is arranged retained on a seal retaining structure, in particular in a retaining groove (26), of one of the two machine parts (12, 14), and having a sealing head (28) that bears with a sealing section (30) in a dynamically sealing manner against a sealing face (32) of the respective other machine part (12, 14) so as to seal a high-pressure side (H), that can be charged with pressurized fluid, of the sealing gap (18) with respect to a low-pressure side (N) of the sealing gap (18), wherein the sealing head (28) and the root section (24) are connected to one another by an elastically deformable connection section (34) of the seal element (20), which has at least in certain sections a non-linear cross-sectional profile and multiple regions (48) of weakened material which are arranged spaced apart from one another in sequence, preferably regularly, in the circumferential direction of the seal element (20). The invention also relates to a seal element (20) for an above-mentioned seal arrangement (10).

Abrégé

The invention relates to a seal arrangement (10) comprising: - a first and a second machine part (12, 14) which are arranged spaced apart from one another with the formation of a sealing gap (18) and can be moved relative to one another about a movement axis (16); - a seal element (20) with a base section (24) which is arranged such that it is held on a seal holding structure, in particular a holding groove (26) of one of the two machine parts (12, 14), and having a sealing head (28) which bears in a dynamically sealing manner by way of a sealing section (30) against a sealing surface (32) of the respective other machine part (12, 14), in order to seal a high pressure side H of the sealing gap (18) with respect to a low pressure side N, which high pressure side H can be pressurized by way of a fluid, wherein the seal element (20) is provided on the high pressure side with at least one flow element (66, 68, 92, 94), by way of which a fluid flow is brought about in the case of a relative movement of the two machine parts (12, 14), in such a way that the sealing head (28) is flowed onto by the fluid on the high pressure side in the region of the sealing section (30) of said sealing head (28). Moreover, the invention relates to a seal element (20) for a seal arrangement of this type.
