Common Varieties and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which contain C and F common hubs and sleeves, Mill Motor hubs, Vertical type, Floating Shaft, and Spacer styles. ’s exceptional engineering employees make it attainable to support lots of added coupling sorts such because the Brakedrum form, Sliding Hub form, Shear Pin variety, Jordan kind, and custom lengths for non normal shaft separations. Further size ranges and models to meet unusual application specifications could also be manufactured by to meet market demands. Material can range from normal steel to alloy steel as well as stainless steel. The excellent simplicity of the coupling style and design make this all attainable.
Misalignment and End-Float Capability
The basic principle of Sier-Bath C and F kind couplings is just like that of other standard flexible gear couplings. Even though it truly is desirable to align shafts as accurately as possible, the objective of any versatile coupling should be to absorb probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings use a one of a kind gear tooth geometry produced exclusively to resolve concerns with shaft misalignment and accommodate from 1/2° to 1-1/2° per gear mesh or flex plane. The hub teeth are absolutely crowned to provide for any larger make contact with region and reduced stresses below misaligned ailments. The crowned tooth design and style also eliminates almost all of the finish loading that takes place on straight gear teeth underneath misalignment.
