Normal Styles and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which incorporate C and F conventional hubs and sleeves, Mill Motor hubs, Vertical design, Floating Shaft, and Spacer types. ’s excellent engineering personnel make it probable to help numerous additional coupling sorts such because the Brakedrum sort, Sliding Hub kind, Shear Pin sort, Jordan form, and custom lengths for non common shaft separations. Extra size ranges and models to meet uncommon application needs may also be manufactured by to meet marketplace demands. Materials can vary from normal steel to alloy steel and even stainless steel. The exceptional simplicity from the coupling style make this all achievable.
Misalignment and End-Float Capability
The essential principle of Sier-Bath C and F style couplings is similar to that of other traditional versatile gear couplings. Though it’s desirable to align shafts as accurately as you possibly can, the objective of any flexible coupling is usually to soak up probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings employ a special gear tooth geometry developed specifically 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 fully crowned to provide to get a bigger contact region and decrease stresses underneath misaligned situations. The crowned tooth design and style also eliminates almost all of the end loading that takes place on straight gear teeth below misalignment.
