Jakob Antriebstechnik introduces new elastomer coupling
The elastomer couplings from Jakob have been expanded by a new series. With the new EKM-VA, the tried-and-tested EKM type has a stainless steel version. One of the strengths of the material is its resistance to chemicals, such as those used for cleaning in the food industry.
Elastomer couplings are pluggable, backlash-free and flexible shaft couplings for all small and medium torques up to 2000 Nm. The connecting and compensating element is a plastic star with involute-shaped teeth and a high Shore hardness. This is inserted in a form-fitting manner with a slight preload in two high-precision hubs with claw-shaped cams. The flexible star coupling can compensate for minor shaft misalignments, is electrically isolating and has good vibration damping properties.
There are several standard variants with a backlash-free, non-positive shaft-hub connection to choose from, which ensure reliable torque transmission even without an additional feather key. The series EKM, ESM-A, EKH and EKS with expansion cone are available in the standard range, individual solutions are also possible on request.
