Technical informationDesign tips

There is a linear ratio, between the transmittable torqueand the tightening torque for the screw, for ETP-EXPRESSand ETP-TECHNO.The torque can be roughly selected forwhen the connection slips, by proper choice of hub/shafttolerances and tightening torque.The connection can thenbe used as an overload protection with limited slipping. Long thin professional rollers subjected to high bending torque, can befastened to stub industrial shafts with ETP-HYLOC.To decrease theelastic deformation of the roller and make it easier to takeup the bending torque, the inner part of the hub and thestub shaft can be designed with conical support surfaces.ETP-HYLOC gives good concentricity and fast changes. ETP-HYCON S is a hydro-mechanical shaft-shaft couplingfor high torque and rigidity.The mounting is done, as forETP-HYLOC, with an external pumping.The design is typeapproved by for example DNV for use in the drive line forships.Other important applications are in the steel-, paper-and other heavy industry, where the requirements are forhigh torque, low weight, high rigidity and short down time. ETP-OCTOPUS is a connection where the pressure settingis done with an external pressure source.Suitable applicationsare when repositioning of parts are to be done frequently,fast and precise.Several connections can be clamped/loosened simultaneously.
