Type HK couplings were developed for encoders required to meet stringent demands with regard to precision, backlash-free angular transmission or torsional rigidity. The metal couplings with spring-type compensating elements are extremely robust and suitable for use in extremely harsh operating conditions.
Advantages of metal couplings from Huebner Giessen:
■Couplings HK 5 / HKD 5 made of stainless steel (for deployment in aggressive environments)
■Increase encoder signal quality by minimizing rotational frequency modulation/harmonics
■Compensate to the best possible degree fitting errors such as shaft misalignment, radial eccentricity and axial shaft movements (e.g. thermal expansion)
■Compensate angular offset with low distortion forces (increases service life of bearings)
■Compensate parallel misalignment (drive shaft to encoder shaft) with double-joint coupling
■Type HKI insulated couplings available to protect against bearing/shaft currents
