Coupling description GEARex® couplings made from steel with grease lubrication and toroidal sealing ring correspond to the international standard. Being flexible shaft connections they are suitable for a positive torque transmission. In addition, they ensure to compensate for axial, radial and angular shaft displacements. GEARex® couplings are used in every range of general engineering requesting for high operating safety and a long service life resulting from the reliable grease lubrication of the crowned spline. The couplings are suitable for horizontal assembly. As special solutions they are suitable for vertical assembly, too. Numerous coupling sizes for a torque transmission from 930 Nm to 135.000 Nm with shaft dimensions up to a maximum of Ø 276 mm are available. The coupling torques may be increased by using special materials. GEARex® couplings are in correspondence with the AGMA standard (American Gear Manufacturer Association). Small dimensions and a low weight along with a small mass moment of inertia result in a wide range of applications of GEARex® couplings.
Operating principle
Explosion protection use
GEARex® couplings are suitable for power transmission in drives in hazardous areas. The couplings are certified and confirmed according to EC standard 94/9/EC (ATEX 95) as units of category 2G/2D and thus suitable for the use in hazardous areas of zone 1, 2, 21 and 22.
