Regular Varieties and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which include things like C and F regular hubs and sleeves, Mill Motor hubs, Vertical design, Floating Shaft, and Spacer designs. ’s exceptional engineering staff make it attainable to support numerous additional coupling varieties such because the Brakedrum kind, Sliding Hub sort, Shear Pin variety, Jordan variety, and customized lengths for non standard shaft separations. Further size ranges and patterns to meet uncommon application requirements can also be produced by to meet industry demands. Material can range from typical steel to alloy steel and in many cases stainless steel. The excellent simplicity in the coupling style make this all feasible.
Misalignment and End-Float Capability
The basic principle of Sier-Bath C and F kind couplings is similar to that of other conventional flexible gear couplings. Even though it is desirable to align shafts as accurately as possible, the objective of any flexible coupling would be to absorb probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings use a unique gear tooth geometry designed especially 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 fully crowned to supply to get a larger make contact with spot and reduce stresses below misaligned conditions. The crowned tooth design also eliminates nearly all of the finish loading that takes place on straight gear teeth beneath misalignment.
