Common Kinds and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which incorporate C and F common hubs and sleeves, Mill Motor hubs, Vertical style, Floating Shaft, and Spacer types. ’s superb engineering personnel make it probable to assistance lots of additional coupling types such as the Brakedrum form, Sliding Hub type, Shear Pin variety, Jordan sort, and custom lengths for non common shaft separations. Supplemental size ranges and types to meet unusual application demands can also be produced by to meet industry demands. Materials can range from common steel to alloy steel and in some cases stainless steel. The excellent simplicity on the coupling style make this all achievable.
Misalignment and End-Float Capability
The fundamental principle of Sier-Bath C and F sort couplings is much like that of other typical flexible gear couplings. Whilst it can be desirable to align shafts as accurately as possible, the purpose of any flexible coupling is always to absorb probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings make use of a exceptional gear tooth geometry developed 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 totally crowned to provide for any bigger get in touch with spot and reduced stresses under misaligned situations. The crowned tooth style and design also eliminates the vast majority of the end loading that happens on straight gear teeth underneath misalignment.
