Normal Kinds and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which include C and F normal hubs and sleeves, Mill Motor hubs, Vertical design, Floating Shaft, and Spacer models. ’s excellent engineering staff make it achievable to help quite a few extra coupling kinds this kind of as the Brakedrum sort, Sliding Hub variety, Shear Pin sort, Jordan style, and custom lengths for non standard shaft separations. Additional size ranges and types to meet uncommon application prerequisites also can be produced by to meet market place demands. Material can range from regular steel to alloy steel and even stainless steel. The outstanding simplicity with the coupling layout make this all achievable.
Misalignment and End-Float Capability
The basic principle of Sier-Bath C and F type couplings is much like that of other typical flexible gear couplings. Although it’s desirable to align shafts as accurately as is possible, the purpose of any versatile coupling will be to absorb probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings make use of a exclusive gear tooth geometry developed especially to resolve issues with shaft misalignment and accommodate from 1/2° to 1-1/2° per gear mesh or flex plane. The hub teeth are entirely crowned to supply to get a more substantial contact area and reduce stresses under misaligned problems. The crowned tooth style also eliminates nearly all of the finish loading that happens on straight gear teeth beneath misalignment.
