599,843. Shaft couplings. RELIEPHOGRAPHIE, SOC. POUR L'EXPLOITATION DES PROCEDES DE PHOTOGRAPHIE EN RELIEF M. BONNET. Aug. 25, 1945, No. 21862. Convention date, Feb. 6, 1943. [Class 80(ii)] [Also in Group XXII] A bent shaft is straightened by applying a permanent bending force producing a deflection equal and opposite to the amount of bend. A shaft 1 carrying a work-piece 2 is mounted on bearings 3, 4 and has a flange 5 by which it is coupled to a co-axial driving shaft 6 by three studs 8 engaging clearance holes 9 in a flange 7 secured to the driving shaft, which is supported by a bearing near the flange. The flange 5 also carries a driving dog 10 co-operating with a screw 11 in the flange 7 and the flanges are spaced apart by a cone-shaped centre 12 on the shaft 1 engaging a recess 13 in the shaft 6. By tightening the nut on the appropriate stud, a bending force may be applied to the shaft 1 through the flange 5 to produce a deflection equal and opposite to the amount of bend in the shaft. The shaft may have zones of reduced crosssection in which the deflection restoring straightness of the shaft is localised. The centre 12 may be on one of the flanges, or may be replaced by a ball. |
