Title (EN) SPIRAL DRIVE FASTENER WITH FRICTION ENGAGEABLE SURFACE
(FR) VIS A EMPREINTE SPIRALE ET A SURFACE D'ENGAGEMENT A FRICTION
Abstract: front page image
(EN)Interference surfaces are constructed on inner transition surfaces between wings of a fastener having a spiral recess. A portion of the transition surface is tapered to provide the interference. A standard driver for a spiral recess will engage the interference surface to create a 'stick fit' engagement. The punch is formed using a wire EDM operation to construct tapered surfaces within the die cavity of a hob. The hob is machined down to obtain the desired depth, which is measured up from a gage spot indicative of the sticking point.
(FR)On forme des surfaces d'interférence sur des surfaces intérieures de transition situées entre les lobes d'une vis à empreinte spirale. Une partie de la surface de transition est conique pour assurer l'interférence. Un tournevis normal pour empreinte spirale entre en contact avec la surface d'interférence pour créer un couplage adhérent. Un poinçon est formé par électroérosion filaire de manière à créer les surfaces coniques de la cavité de la matrice du poinçon, lequel est usiné jusqu'à la profondeur désirée mesurée depuis la graduation d'un calibre indiquant le point d'adhérence.
