Regular 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 fashion, Floating Shaft, and Spacer types. ’s excellent engineering staff make it feasible to support numerous extra coupling forms this kind of since the Brakedrum variety, Sliding Hub form, Shear Pin form, Jordan type, and custom lengths for non regular shaft separations. Additional dimension ranges and models to meet uncommon application needs can also be manufactured by to meet marketplace demands. Material can range from normal steel to alloy steel as well as stainless steel. The excellent simplicity from the coupling layout make this all doable.
Misalignment and End-Float Capability
The basic principle of Sier-Bath C and F sort couplings is just like that of other conventional versatile gear couplings. Whilst it truly is desirable to align shafts as accurately as possible, the goal of any flexible coupling would be to absorb probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings make use of a unique gear tooth geometry produced particularly 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 entirely crowned to supply for any larger get in touch with location and reduced stresses beneath misaligned conditions. The crowned tooth design also eliminates almost all of the finish loading that occurs on straight gear teeth below misalignment.
