Diaphragm couplings

Highest torques are safely and reliable transmitted at the highest speed via a contoured single diaphragm. Power ranges of up to 150 MW can be easily accommodated to match our high-speed gear units. The unique contoured diaphragm and its flexibility allow the compensation of axial, radial and angular misalignments.

Our diaphragm couplings are maintenance-free and stand out for their extremely long service life along with maximum availability. Plus, the basic version consists of just a few components, which simplifies assembly and handling significantly for the user.

High Performance Diaphragm Couplings

Diaphragm Couplings allow the transmission of torque. They can handle misalignment, based on the thickness distribution (or profile) of the diaphragm. Unlike competing designs, we use a single stainless steel diaphragm. This eliminates the need for extra bolts, rivets, splines and filler rings.

It also greatly simplifies the task of shaping the perfect diaphragm, since we need only one diaphragm per end. We use a modified profile based on extensive FEA. The thickness of the diaphragm varies so stress is distributed evenly when the diaphragm flexes. This happens under the simultaneous effects of torque, speed, axial misalignment and angular misalignment.
