Standard Types and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which include C and F typical hubs and sleeves, Mill Motor hubs, Vertical design, Floating Shaft, and Spacer models. ’s excellent engineering workers make it attainable to help many additional coupling styles such since the Brakedrum variety, Sliding Hub kind, Shear Pin style, Jordan style, and custom lengths for non conventional shaft separations. Supplemental size ranges and patterns to meet uncommon application requirements could also be produced by to meet market demands. Materials can vary from standard steel to alloy steel and in some cases stainless steel. The exceptional simplicity with the coupling style and design make this all feasible.
Misalignment and End-Float Capability
The essential principle of Sier-Bath C and F type couplings is just like that of other standard flexible gear couplings. When it is desirable to align shafts as accurately as you can, the objective of any flexible coupling is usually to soak up probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings utilize a exclusive gear tooth geometry created especially to resolve challenges with shaft misalignment and accommodate from 1/2° to 1-1/2° per gear mesh or flex plane. The hub teeth are absolutely crowned to provide to get a larger make contact with spot and decrease stresses beneath misaligned conditions. The crowned tooth style also eliminates the majority of the end loading that happens on straight gear teeth underneath misalignment.
