What is windage and how to reduce it?
Windage is resistance that atmospheric air provides to any rotating body. Since all couplings for safety reasons need to necessarily have coupling guards, it is very important that the coupling guards are properly designed to reduce windage and its related problems like temperature rise, high frequency sound, oil sucking from bearings etc. Apart from the benefits which are derived from proper design of the guards, the Euroflex coupling recognizes the importance of windage related problem and offers certain design solutions on the coupling itself for windage reduction. The figures shown below show the design changes adopted in the form of introducing shrouding and windage plates on high speed couplings. The design modifications given above generally meet most requirements. Should the need arise, Euroflex also offers streamlined designs, which not only offers a smoother surface to the unit, but also eliminates the rapid changes in the coupling profile and hence introduces the best possib
