Shaft-hub connections INKOMA-Shaft-hub connection components provide a cost saving. standardised range of machine components without compromise on The various designs provide simple, yet secure and reliable methods, for the transmission of torque and rotation. Since the beginning of the last century patents have existed for the manufacture of a near triangular form. Several decades were to pass before economic manufacture of Polygon profiles was Polygon profiles are mainly for the transmission of torque. They are a complete replacement for other profiles, splined, keyed etc. Compared with most traditional forms there is no notching effect and hence no influence The Polygon profile has more than 30% greater fatigue resistance than similarly sized alternative profiles. The complete product range has ready-to-assemble Polygon shafts, hubs, clamprings and sliding naves. INKOMA- GROUP

Shaft-hub connections P3G-Polygon profile to DIN 32711 Splines similar to ISO 14 INKOMA-P3G-Polygon profiles have the following properties: A new way of saving costs without compromising quality. 1. The P3G-Polygon profile is designed for use where stable shafthub connections exist. It is unsuitable for applications having axial sliding under load 2. Self centering 3. Compared with Splined profiles INKOMA-P3G-Polygon profiles have aproximately 30% higher fatigue resistance 4. The shaft profile is produced by grinding 5. Both broaching and grinding are used for the manufacture of hub components...
