Why Face-Gear Serrated Flanges Outperform Flat Flanges in SWC315BH Industrial Cardan Shafts
Introduction In high-torque industrial drivetrains—such as primary roll stands in steel mills, paper mill presses, and heavy shredder drives—traditional flat friction flanges can experience micro-slippage when subjected to rapid torque reversals and heavy shock loads. Over time, this slippage shears mounting bolts and causes unplanned production downtime.
The SWC315BH Face-Gear Flange Cardan Shaft eliminates friction dependency by incorporating precision 60-tooth radial face serrations across its connection faces.
1. The Mechanical Advantage of 60-Tooth Hirth Face Serrations Unlike smooth-faced flanges that rely entirely on bolt clamping force to transfer torque via surface friction, face-gear flanges utilize intermeshing triangular or trapezoidal teeth.
Zero Angular Slippage: The 60-tooth serration transfers torsional load directly throughtooth flanks.
Reduced Shear Strain on Fasteners: Bolt hole centers are positioned in line with toothroots (grooves), ensuring the 12 mounting bolts (M23 size) operate primarily under axialtension rather than destructive shear forces.
Self-Centering Accuracy: Radial tooth geometry provides automatic self-centeringduring flange bolt tightening.
2. Engineering Specification Verification Checklist Before ordering replacement cardan assemblies for existing mill stands, plant engineers must verify the key physical dimensions of the SWC315BH:
3.
