Common Styles and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which involve C and F common hubs and sleeves, Mill Motor hubs, Vertical fashion, Floating Shaft, and Spacer patterns. ’s excellent engineering employees make it attainable to support many extra coupling forms such as the Brakedrum sort, Sliding Hub sort, Shear Pin sort, Jordan kind, and customized lengths for non standard shaft separations. Supplemental dimension ranges and styles to meet unusual application necessities may also be manufactured by to meet industry demands. Materials can range from common steel to alloy steel as well as stainless steel. The excellent simplicity on the coupling style and design make this all probable.
Misalignment and End-Float Capability
The fundamental principle of Sier-Bath C and F type couplings is much like that of other conventional flexible gear couplings. When it’s desirable to align shafts as accurately as you possibly can, the objective of any versatile coupling is usually to absorb probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings use a one of a kind gear tooth geometry formulated exclusively 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 supply for a more substantial get hold of location and reduce stresses underneath misaligned disorders. The crowned tooth design and style also eliminates the vast majority of the end loading that occurs on straight gear teeth underneath misalignment.
