Definitions
- the invention relates to a bellows for sealing a swivel joint, with a first collar of larger diameter for fixing on an outer joint part of the swivel joint and with a second collar of smaller diameter for fixing on a shaft on an inner joint part of the swivel joint and a half-toroidal, connecting the bundle-shaped wall.
- roller bellows are preferable to the bellows, which are also known, since they are less sensitive to the action of high centrifugal forces and remain dimensionally stable even under the influence of the grease filling of the joint.
- a roller bellows of this type is known from DE 195 44 911 A1.
- a bellows made of thermoplastic elastomer is described in DE 40 37 482 A1.
- the object of the present invention is to provide a rolling bellows which can withstand extreme loads conditions, ie very high flexion angles even at high speeds over the entire joint life with common load spectra.
- the bellows is an injection molded or blow molded product, the bellows consists of a thermoplastic elastomer, the elastomer is irreversibly cross-linked to a degree between 15 and 85%.
- thermoplastic elastomer in injection molding or blow molding and the subsequent irreversible crosslinking of the thermoplastic elastomer used in the range of a degree of crosslinking of between 15 and 85% is essential for the desired dimensional stability even at high speeds and high bending angles.
- a cross-linking chemical nature the elastomer loses its thermoplastic property.
- the irreversible crosslinking provides effective protection against undesired deformations at temporarily high operating temperatures of the rolling bellows.
- the bellows according to the invention can thus be damage-free increased loads, d. H.
- the rolling bellows can be manufactured with increased precision, in particular with a wall thickness that is exactly maintained, so that the influence of unbalance can be significantly reduced. In view of the desired high speeds, this is of particular importance.
- the crosslinking according to the invention is by chemical or thermal processes or in particular by irradiation of the Manufacture injection molded part with ß- or y-rays.
- the crosslinking of polymers and rubber under the influence of high-energy radiation is known as such, for example by G. Schreier, constructing with plastics, Kunststoff, 1972.
- thermoplastic elastomers which have the required strength properties and which can be crosslinked in the desired manner, those based on ester are proposed.
- Values of 45 to 65 ° can be given as particularly preferred ranges of the degree of crosslinking, in which on the one hand the flexibility of the rolling bellows is still sufficiently large, on the other hand the improved properties with regard to mechanical strength and temperature resistance are significantly increased.
- roller bellows according to the invention and suitable methods for its production are mentioned in the subclaims, to which reference is hereby made.
- a quadripode joint 1 with an inserted shaft 2 and a rolling bellows 3 is shown in a longitudinal section.
- the bellows has in the usual way an outer collar 4 which is bead-shaped and which is clamped to a ring part 6 with a retaining ring 5.
- This ring part 6 is in turn clamped on the outer joint part 7 of the quadripode joint 1.
- the outer joint part 7 has a flange 8 for connection to a first connection part.
- a second collar 9 of the rolling bellows is fixed on the shaft 1 by means of a tensioning band 10.
- This shaft 1 is inserted into the inner joint part 11 of the joint 1.
- the first collar 4 and the second collar 9 are substantially uniform over one thick semi-toroidal Baigwand 12 connected to each other, which thus seals the joint on the shaft side.
- the shape of the bellows is essentially the same as that of the prior art.
- the bellows according to the invention is produced in the form shown as an injection molded product.
