Aanhaalmoment versus klembelasting

Voorgestelde startwaarden

De hieronder geschatte koppelberekeningen worden alleen als richtlijn aangeboden. Het gebruik van de inhoud door iedereen is de exclusieve verantwoordelijkheid van die persoon en zij nemen alle risico's.

 

Vanwege de vele variabelen die van invloed zijn op de koppel-spanningrelatie, zoals menselijke fouten, oppervlaktestructuur en smering, is de enige manier om het juiste koppel te bepalen, door te experimenteren onder werkelijke verbindings- en montageomstandigheden.
