Note
Elastomer dog coupling consisting of two hubs and an elastomer coupling spider. They are suitable for compensating axial, radial and angular misalignments and for cushioning vibrations and torque shocks.
The polyurethane coupling spiders are available in various hardness grades. As the hardness of the coupling spider increases, the torque and stiffness transmitted increases, and as the hardness decreases, the displacement capacity and cushioning increases.
Pre-tensioning of the spiders in the coupling hubs make this variant play-free.
Supplied unassembled.

Assembly
Les accouplements à griffes en élastomère présentent un ajustement H7. Le jeu d'ajustement recommandé est de 0,02 mm - 0,05 mm. Ce jeu d'ajustement et le graissage des tourillons d'arbre facilitent le montage et le démontage.
Au moment du montage, les moyeux de l'accouplement à griffes en élastomère sont enfilés sur les arbres et fixés à l'aide de moyeux de serrage.
