Regular Types and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which include C and F regular hubs and sleeves, Mill Motor hubs, Vertical design, Floating Shaft, and Spacer models. ’s excellent engineering staff make it feasible to help a lot of extra coupling kinds this kind of as the Brakedrum kind, Sliding Hub sort, Shear Pin kind, Jordan style, and custom lengths for non standard shaft separations. Additional size ranges and patterns to meet uncommon application prerequisites may also be produced by to meet industry demands. Materials can range from standard steel to alloy steel and in many cases stainless steel. The outstanding simplicity with the coupling design and style make this all feasible.
Misalignment and End-Float Capability
The essential principle of Sier-Bath C and F style couplings is much like that of other typical flexible gear couplings. Whilst it’s desirable to align shafts as accurately as is possible, the purpose of any versatile coupling is usually to absorb probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings make use of a exclusive gear tooth geometry developed particularly to resolve issues 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 to get a more substantial contact place and reduce stresses under misaligned situations. The crowned tooth design also eliminates the majority of the end loading that happens on straight gear teeth beneath misalignment.
