Regular Kinds and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which include things like C and F typical hubs and sleeves, Mill Motor hubs, Vertical type, Floating Shaft, and Spacer styles. ’s superb engineering workers make it probable to assistance a lot of additional coupling types this kind of because the Brakedrum sort, Sliding Hub sort, Shear Pin sort, Jordan variety, and custom lengths for non standard shaft separations. Extra dimension ranges and styles to meet unusual application needs may also be produced by to meet marketplace demands. Materials can range from conventional steel to alloy steel and in some cases stainless steel. The outstanding simplicity in the coupling layout make this all attainable.
Misalignment and End-Float Capability
The fundamental principle of Sier-Bath C and F form couplings is just like that of other traditional versatile gear couplings. Whilst it is desirable to align shafts as accurately as you can, the function of any flexible coupling is usually to absorb probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings make use of a distinctive gear tooth geometry created exclusively to resolve troubles 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 provide for any greater contact location and lower stresses under misaligned conditions. The crowned tooth style also eliminates the majority of the finish loading that occurs on straight gear teeth under misalignment.
