Large-bore shaft collars and rigid couplings for drive train applications in wind power generation systems are available from Stafford Mfg. Corp.
The collars and couplings are engineered for applications up to 16 and 8 in. ID, respectively, and come in one- and two-piece configurations that can be modified to meet special requirements. They can be precision-balanced and incorporate steel targets that can be read from both the face and OD to add speed-sensing capability to shafts.
The products can be machined from aluminum, steel, stainless steels, titanium, brass, and other alloys with dimensional tolerances of less than 0.001 in. and runout and concentricity tolerances of less than 0.001-in. TIR, depending on the part configuration. Modifications can include keyways, slots, cam surfaces, and special threads.
