Problems solved by technology

However, due to the unlubricated running of the rotary ring seals which is unavoidable with this type of construction, there is increased leakage due to the suction / pump action of the construction when turning in the second direction caused by the backward movement of the device
Without this construction the maximum leakage required by the specification cannot be ensured in both directions of movement
Dry running of the coolant can lead to damage to the rotary ring seal and thus also to the drive, which is embodied, for example, as an electric motor

Embodiment Construction

[0034] Figure 1a The active surface 2 of the ring of the rotary ring seal is shown schematically in a first operating state in which the ring rotates in a first rotational direction, ie clockwise, which is indicated by the arrow 4 . and Figure 1b Shows the active face 2 of the ring turning counterclockwise in the second direction of rotation, which in Figure 1b Indicated by arrow 6.

[0035] In this case, the annular active surface 2 of the ring is subdivided into two annular regions arranged coaxially with one another, an inner region 8 and an outer region 10 . Each zone, ie the inner zone 8 and the outer zone 10, has a surface with a structure which is respectively provided by a laser or by laser machining and thus structured, where the structure provided for each zone is introduced by means of a laser. into the surface of each zone and is provided therefrom.

[0036] Furthermore, the inner zone 8 is delimited by an inner circle 12 with an inner radius and a middle ci...

Abstract

The present invention relates to a ring for a floating ring seal having an active face (2), wherein the active face (2) has an inner zone (8) with a surface and an outer zone (10) with a surface, wherein the outer zone (10) surrounds the inner zone (8) coaxially, wherein each of the two surfaces has a structure produced with a laser.

Description

technical field [0001] The invention relates to a ring for a rotary / slip ring seal and to a rotary / slip ring seal. Background technique [0002] The rotary ring seal is designed, for example, as part of a drive, in which a coolant is used as the fluid. The surface of the rotary ring seal is structured / textured (Strukturieren) in order to prevent fluid leakage during rotation in the first direction caused by the forward movement of the device driven by the drive device, so the structure / constructed in the surface The textured structure acts as a fluid barrier. However, since this type of construction avoids dry running of the rotating ring seal, there is increased leakage due to the suction / pumping action of the construction when turning in the second direction caused by the backward movement of the device. Without this construction, the maximum leakage required by the specification cannot be ensured in both directions of movement. Dry running of the coolant can lead to da...
