Typical Styles and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which include things like C and F normal hubs and sleeves, Mill Motor hubs, Vertical design, Floating Shaft, and Spacer patterns. ’s excellent engineering workers make it possible to support numerous supplemental coupling types such because the Brakedrum sort, Sliding Hub variety, Shear Pin sort, Jordan style, and custom lengths for non standard shaft separations. More size ranges and patterns to meet uncommon application needs may also be produced by to meet industry demands. Material can vary from standard steel to alloy steel and even stainless steel. The outstanding simplicity with the coupling style and design make this all attainable.
Misalignment and End-Float Capability
The essential principle of Sier-Bath C and F variety couplings is just like that of other standard versatile gear couplings. Whilst it truly is desirable to align shafts as accurately as you possibly can, the function of any flexible coupling should be to soak up probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings employ a one of a kind gear tooth geometry formulated specifically 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 make contact with region and decrease stresses underneath misaligned problems. The crowned tooth layout also eliminates most of the end loading that occurs on straight gear teeth beneath misalignment.
