Abstract
1298630 Rolling gears TELEDYNE Inc 21 Dec 1970 [12 Jan 1970] 60689/70 Heading B3M Apparatus for roll-forming a toothed gear W comprises a single toothed tool 38 acting on gear discs 44 and 46 between which the gear W is clamped, and backing rollers 84, 88 which bear on the discs. The two discs are urged towards each other by hydraulic cylinders 64 and 66, the disc 44 having a central stem which passes through the gear and co-operates with a recess in the disc 46 (Fig. 3, not shown). Each disc is acted on by two backing rollers 86 and 84 or 90 and 88 (Fig. 4), the rollers being mounted on a support 98. To position a gear W ready for rolling, the support 98 is lowered by a ram 21, and is then shifted laterally by a toggle lever 110. The gear is positioned between the discs and is supported by the backing rollers. When the gear and rollers are moved back by the toggle lever, the discs are urged together by the cylinders 64 and 66. A stop associated with the cylinder 64 (which is of higher power than the cylinder 66) determines the axial location of the gear. The ram 21 finally urges the gear into rolling contact with the tool 38, the gear being freely rotatable and the tool being driven by an hydraulic motor 36.
