HKK CURVE JAW COUPINGS HITEX COUPINGS
CURVE JAW COUPINGS Coupling selection The HKK jaw coupling selection shoul be mae accoring to IN 740-2. Proper imensioning of the coupling shoul be one to ensure that the permissible coupling loa never is exceee in any operating conition. Verify the rate torque of the application (T N ) by the following formula: T N = 9550 P (kw) n (rpm) Specifications b Torque range 0 7.500 Nm b Torsionally flexible b Failsafe b Vibration reucing b Axial plug-in The nominal torque of the coupling (T KN ) shoul be equal or higher to the application torque taking the ambient tempature in consieration. T KN T N S t The maximum torque of the coupling (T KNmax ) shoul be equal or higher to the peak torque (T S ) multiplie by the servicefactors for temperature (S t ), starting frequency (S Z ) an shocks (S U ). T Kmax T S S t S Z S U The vibratory torque which the coupling (T KW ) can bear shoul be equal or higher to the vibratory torque of the application(t W ) multiplie by the Servicefactor for temperature S t. T KW T W S t Servicefactors Servicefactor for starting frequency S Z Starting frequency per hour 00 200 400 800 S Z,0,2,4,6 Servicefactor for temperature S t Tempature range -30 C +30 C +40 C +60 C +80 C S t,0,2,4,6 Servicefactor for shocks S U Gentle shock loa,5 Meium shock loa,8 Heavy shock loa 2,5 Shaft-hub connection The shaft-hub connection shoul always be verifie by the customer. The maximum torque of the rive shoul always be lower than the torque which the shaft-hub connection can bear. In case of keyway connection it is recommene to verify the permissible surface pressure of the coupling hub. 2
