Regular Kinds and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which contain C and F conventional hubs and sleeves, Mill Motor hubs, Vertical design, Floating Shaft, and Spacer designs. ’s excellent engineering staff make it possible to assistance a lot of further coupling types this kind of since the Brakedrum style, Sliding Hub type, Shear Pin form, Jordan variety, and customized lengths for non normal shaft separations. Supplemental dimension ranges and models to meet uncommon application requirements could also be manufactured by to meet market place demands. Material can range from standard steel to alloy steel and in many cases stainless steel. The exceptional simplicity of the coupling style and design make this all feasible.
Misalignment and End-Float Capability
The fundamental principle of Sier-Bath C and F type couplings is similar to that of other typical versatile gear couplings. While it really is desirable to align shafts as accurately as you can, the purpose of any versatile coupling should be to soak up probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings employ a distinctive gear tooth geometry developed specifically 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 totally crowned to provide to get a larger make contact with spot and reduced stresses underneath misaligned disorders. The crowned tooth design also eliminates nearly all of the finish loading that takes place on straight gear teeth underneath misalignment.
