Normal Forms and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which incorporate C and F normal hubs and sleeves, Mill Motor hubs, Vertical design, Floating Shaft, and Spacer models. ’s exceptional engineering workers make it achievable to support a lot of additional coupling kinds this kind of as the Brakedrum variety, Sliding Hub kind, Shear Pin sort, Jordan style, and customized lengths for non common shaft separations. Further dimension ranges and types to meet unusual application demands can also be manufactured by to meet market demands. Material can range from typical steel to alloy steel and even stainless steel. The exceptional simplicity from the coupling design and style make this all achievable.
Misalignment and End-Float Capability
The essential principle of Sier-Bath C and F kind couplings is much like that of other conventional flexible gear couplings. Whilst it is desirable to align shafts as accurately as you can, the function of any versatile coupling will be to soak up probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings use a special gear tooth geometry designed specifically to resolve concerns with shaft misalignment and accommodate from 1/2° to 1-1/2° per gear mesh or flex plane. The hub teeth are completely crowned to supply for any more substantial speak to region and reduced stresses below misaligned conditions. The crowned tooth layout also eliminates almost all of the end loading that takes place on straight gear teeth underneath misalignment.
