Common Varieties and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which involve C and F normal hubs and sleeves, Mill Motor hubs, Vertical type, Floating Shaft, and Spacer types. ’s exceptional engineering personnel make it possible to assistance lots of added coupling forms such as the Brakedrum form, Sliding Hub form, Shear Pin sort, Jordan form, and customized lengths for non standard shaft separations. More size ranges and patterns to meet uncommon application demands also can be manufactured by to meet market demands. Material can vary from regular steel to alloy steel as well as stainless steel. The outstanding simplicity on the coupling layout make this all achievable.
Misalignment and End-Float Capability
The essential principle of Sier-Bath C and F kind couplings is similar to that of other typical flexible gear couplings. Although it is actually desirable to align shafts as accurately as you possibly can, the goal of any versatile coupling will be to absorb probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings use a unique gear tooth geometry developed 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 fully crowned to supply for any greater contact location and decrease stresses below misaligned problems. The crowned tooth design and style also eliminates the vast majority of the finish loading that takes place on straight gear teeth beneath misalignment.
