As machines rotate, they lose alignment
. Wear and tear also cause deviation. The Phase Adjusting Hub is a precision device used to fine-tune timing adjustments. It also acts as a tooth wear sprocket and for chain elongation adjustments. It achieves a 24-degree adjustment calibrated with a plus or minus 12-degree change.A Phase Adjusting Hub has four components; the Adjusting Ring, Flexspline, and two Hubs
; the S and D. These components work seamlessly under the harmonic drive principle. The adjusting ring has an ellipse-like hole where the Flexspline is inserted. Also, the Flexspline has teeth or grooves on the inner side that connect with the two hubs whose teeth are found on the outside.In its normal state, the Phase Adjusting Hub remains intact and acts as a coupling. However, every manual rotation of the Adjusting Ring triggers micro-adjustment, where the two hubs and the Flexspline work in harmony to rectify the deviation.Get the right phase adjusting hub for your specific application. We stock a wide assortment of hubs to suit any task.
