Typical Types and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which incorporate C and F standard hubs and sleeves, Mill Motor hubs, Vertical fashion, Floating Shaft, and Spacer models. ’s excellent engineering workers make it attainable to help a lot of additional coupling forms this kind of as the Brakedrum style, Sliding Hub kind, Shear Pin variety, Jordan form, and customized lengths for non conventional shaft separations. Additional dimension ranges and patterns to meet unusual application requirements also can be produced by to meet market demands. Material can range from typical steel to alloy steel and in some cases stainless steel. The excellent simplicity with the coupling layout make this all achievable.
Misalignment and End-Float Capability
The fundamental principle of Sier-Bath C and F form couplings is similar to that of other traditional versatile gear couplings. Though it can be desirable to align shafts as accurately as you can, the goal of any flexible coupling is usually to absorb probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings utilize a exceptional gear tooth geometry designed specifically to resolve difficulties 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 for a more substantial speak to location and reduced stresses under misaligned circumstances. The crowned tooth design and style also eliminates the vast majority of the end loading that takes place on straight gear teeth below misalignment.
