Common Forms and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which include things like C and F common hubs and sleeves, Mill Motor hubs, Vertical type, Floating Shaft, and Spacer styles. ’s excellent engineering employees make it possible to support numerous added coupling forms this kind of because the Brakedrum type, Sliding Hub sort, Shear Pin kind, Jordan style, and customized lengths for non common shaft separations. Supplemental dimension ranges and types to meet uncommon application necessities may also be produced by to meet market demands. Material can vary from conventional steel to alloy steel and even stainless steel. The excellent simplicity of the coupling layout make this all possible.
Misalignment and End-Float Capability
The fundamental principle of Sier-Bath C and F style couplings is much like that of other traditional versatile gear couplings. Though it truly is desirable to align shafts as accurately as possible, the function of any versatile coupling is to absorb probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings utilize a exclusive gear tooth geometry formulated exclusively 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 totally crowned to supply to get a larger contact spot and decrease stresses below misaligned situations. The crowned tooth style also eliminates the vast majority of the finish loading that takes place on straight gear teeth beneath misalignment.
