Problems solved by technology

The farther the torsional stop is located between the slip ring and / or stationary ring and the elastomer part away from the high load area, the more likely it is to cause an elastic deformation of the torsional stop, in which case the shape is no longer guaranteed. The snap-fit ​​connection then no longer guarantees a torsional lock

Embodiment Construction

[0017] figure 1 The slide ring and / or stationary ring 1 of the transmission seal, which is not further described here, is shown. The slip ring and / or stationary ring, referred to below as slip ring, comprises a radial side 2 and an axial side 3 . A sliding surface 4 is provided on the radial side. The axial side 3 receives an elastomer body 5 designed as a trapezoidal seal.

[0018] The free ends of the axial sides 3 are provided with recesses 6 which, viewed in the tangential direction, form a torsion lock, into which recesses 6 are formed approximately correspondingly formed projections 7 of the sealing body 5 .

[0019] In contrast to the prior art, a corresponding anti-twist lock is provided by means of a corresponding shape of the projection 7 in the vicinity of the highly loaded contact area 8, ie towards the transition from the radial side 2 to the axial side 3 direction. For this purpose, a formation 9 is provided in the transition region between the radial side 2 ...

Abstract

The invention relates to a slide ring seal, in particular a running gear seal, at least comprising an angled slide ring and / or counter ring, the radial limb of which is provided with a sliding surface and the axial arm of which forms a seat for a trapezoidal sealing element, wherein the outer end of the axial limb has recesses in which lugs engage, wherein said lugs are moulded on the sealing element and form anti-turn devices. The transition region from the axial limb to the radial limb of the slide ring and / or counter ring provided beyond the sliding surface has a profiling, in which an approximately correspondingly constructed section of the sealing element engages.

Description

technical field [0001] The invention relates to a slip ring seal forming part of the stated type according to the first claim, in particular a transmission seal. Background technique [0002] Transmission seals using rubber trapezoidal rings have only low holding moments between the elastomer part and the slip ring and / or stationary ring due to the low forces generated by the elastomer part. Already subjected to moderate dirt attack from the outside which increases torsional forces, torsion can develop between the elastomer part and the slip ring and / or the stationary ring. [0003] Increased loads, for example due to dirt damage and corrosion, can lead to increased torques between the slip ring and / or stationary ring and the elastomer part. The relative movement between the slide ring and / or stationary ring and the elastomer part leads to wear of the elastomer and thus subsequent failure of the seal. [0004] A sliding ring seal of the mentioned type with a radial torsion...
