Typical Styles and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which contain C and F standard hubs and sleeves, Mill Motor hubs, Vertical design, Floating Shaft, and Spacer models. ’s exceptional engineering workers make it probable to support lots of added coupling varieties such because the Brakedrum variety, Sliding Hub kind, Shear Pin type, Jordan kind, and customized lengths for non normal shaft separations. Additional size ranges and patterns to meet uncommon application needs could also be manufactured by to meet market place demands. Materials can vary from normal steel to alloy steel and in some cases stainless steel. The outstanding simplicity in the coupling layout make this all probable.
Misalignment and End-Float Capability
The fundamental principle of Sier-Bath C and F variety couplings is similar to that of other conventional versatile gear couplings. Though it’s desirable to align shafts as accurately as you possibly can, the purpose of any flexible coupling would be to absorb probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings employ a exclusive gear tooth geometry produced particularly 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 thoroughly crowned to provide to get a larger contact area and reduce stresses below misaligned problems. The crowned tooth design also eliminates most of the end loading that happens on straight gear teeth below misalignment.
