Abstract

1499946 Making crank-shafts DRESSER INDUSTRIES Inc 30 March 1976 [21 April 1975] 12772/76 Heading B3A [Also in Division F2] A method of forming a crank-shaft having one or more eccentric journals thereon comprises a shaft 11, forming one or more journal discs 17a, 17b, 17c and fitting the discs on the shaft. The discs are a press-fit on shoulders on the shaft and are welded to the shoulders. Alternatively the shaft may have no shoulders, and/or the discs may be keyed to the shaft. A gear plate 22 may also be fitted on the shaft. After the discs have been pressed on shaft 11, it is preferable that the shaft is heated to 500‹ F., the welding done at this temperature, and afterwards the shaft and discs heated to 600‹ F. and slowly cooled, then stress relieved by heating to 1200‹ F. and held there for 8 hours. Shaft 11 may be cut from bar stock or may be cast or forged. The discs may be cut from plate or large diameter rod. The crankshaft assembled for a triplex pump is shown in Fig. 5 (and Fig. 6, not shown). Shaft 11 is supported at its ends in roller bearings in the pump housing, is driven by a gear 30 fastened to plate 22 and drives by means of eccentric journals 17 connecting rods located by roller bearings thereon, and connected to pump pistons.
