Common Varieties 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 fashion, Floating Shaft, and Spacer types. ’s fantastic engineering workers make it attainable to assistance many added coupling types such because the Brakedrum kind, Sliding Hub variety, Shear Pin kind, Jordan sort, and customized lengths for non common shaft separations. Added size ranges and models to meet uncommon application specifications also can be manufactured by to meet market demands. Material can range from normal steel to alloy steel and in some cases stainless steel. The exceptional simplicity of the coupling style make this all achievable.
Misalignment and End-Float Capability
The fundamental principle of Sier-Bath C and F style couplings is similar to that of other traditional flexible gear couplings. Although it’s desirable to align shafts as accurately as possible, the goal of any versatile coupling should be to soak up probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings employ a exclusive gear tooth geometry produced especially to resolve problems with shaft misalignment and accommodate from 1/2° to 1-1/2° per gear mesh or flex plane. The hub teeth are completely crowned to provide for any more substantial get hold of spot and lower stresses beneath misaligned situations. The crowned tooth design also eliminates almost all of the finish loading that occurs on straight gear teeth beneath misalignment.
