Abstract

955,243. Rolling crank-shaft fillets. BRISTOL SIDDELEY ENGINES Ltd. Nov. 28, 1962 No. 45063/62. Headings B3A and B3M. A method of cold-working the fillet radii of a crank-shaft comprises the steps of machining the radii and then cold-rolling them, using one or more rollers, the crosssection of each roller in a plane through its axis of rotation, having a portion of radius approximately equal to that of the fillet radius and an adjacent portion of larger radius, the radii running smoothly into one another and preventing formation of cusps at the edges of the radii during rolling. A typical roller profile is shown in Fig. 5 where a roller 94 is provided with radii r<SP>2</SP> and r<SP>3</SP> and also portions 97 and 101 of infinite radius (straight profiles). A rolling tool comprises arms 2 and 3, hinged at 4, which support holders 8, 9 and 10 on to which are hingedly fixed rollers 69, one at least of the rollers being of the profile described. In operation, the arms are put round a workpiece and a bolt 31 is inserted through a cam assembly 49, lugs 13 and 14, and a sleeve 37, and is held by a spring C-washer 46. A spring 41, acting between a collar 39 and an adjustable nut 42 pinned to the lug 14, exerts a force urging the arms and rolls inwardly. Full working pressure on the rolls is effected by rotating, by means of a tommy bar, a movable wedge member 55 relative to a similar fixed member 53, wedge surfaces on the members urging the two members apart to further compress the spring. Small flattened portions on the wedge surfaces allow the members to remain in this held apart condition. Fig. 8 shows how rolls 130 are supported in relation to a workpiece whose fillets are being rolled.
