Normal Forms and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which incorporate C and F typical hubs and sleeves, Mill Motor hubs, Vertical style, Floating Shaft, and Spacer designs. ’s exceptional engineering workers make it feasible to help quite a few supplemental coupling forms such because the Brakedrum variety, Sliding Hub variety, Shear Pin variety, Jordan type, and custom lengths for non normal shaft separations. Supplemental size ranges and designs to meet unusual application demands also can be manufactured by to meet market place demands. Material can range from typical steel to alloy steel and also stainless steel. The outstanding simplicity of your coupling style make this all achievable.
Misalignment and End-Float Capability
The essential principle of Sier-Bath C and F form couplings is much like that of other traditional flexible gear couplings. While it truly is desirable to align shafts as accurately as is possible, the purpose of any versatile coupling should be to soak up probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings utilize a special gear tooth geometry formulated particularly 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 completely crowned to supply to get a more substantial speak to place and decrease stresses underneath misaligned conditions. The crowned tooth design and style also eliminates almost all of the finish loading that takes place on straight gear teeth under misalignment.
