Common Types and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which consist of C and F common hubs and sleeves, Mill Motor hubs, Vertical style, Floating Shaft, and Spacer patterns. ’s superb engineering workers make it probable to assistance lots of additional coupling styles such as the Brakedrum sort, Sliding Hub type, Shear Pin sort, Jordan sort, and custom lengths for non common shaft separations. Supplemental size ranges and styles to meet unusual application demands can also be produced by to meet marketplace demands. Materials can range from regular steel to alloy steel and in some cases stainless steel. The excellent simplicity on the coupling style make this all possible.
Misalignment and End-Float Capability
The basic principle of Sier-Bath C and F type couplings is similar to that of other typical flexible gear couplings. Whilst it really is desirable to align shafts as accurately as possible, the function of any flexible coupling is to absorb probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings utilize a special gear tooth geometry developed especially 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 to get a larger contact region and reduced stresses under misaligned circumstances. The crowned tooth style and design also eliminates the vast majority of the end loading that happens on straight gear teeth underneath misalignment.
