Abstract
A force-transmitting, cone-shaped press-fit connection of metallic materials is provided between a shaft, an axle, or a pin and a hub, a disk, a wheel, or the like. An integral joint is formed with an anaerobic adhesive disposed in the residual roughness intermediate spaces of a joint slot adjoining a pressed-in conical seat having an oversize. The axial securing of the cone press-fit connection against loosening is performed predominantly via the integral joint formation.

A force-transmitting, funnel-shaped press-fit connection comprising
- a shaft member having an outer conical rotation-symmetrical surface, thus forming a rotation-symmetrical seat;
- a hub member having an inner conical rotation-symmetrical surface matched to the outer rotation-symmetrical surface of the shaft member, wherein the hub member and the shaft member are placed into a mutually engaged position thereby forming an intermediate space of a joint slot;
- an anaerobic adhesive disposed in residual roughness present at the intermediate space of the joint slot adjoining the pressed-in rotation-symmetrical seat having an oversize thereby forming an integral joint between the shaft member and the hub member.

A method for producing a force-transmitting, funnel-shaped press-fit connection comprising
- machining a shaft member having an outer rotation-symmetrical conical surface thus forming a rotation-symmetrical seat;
- machining a hub member having an inner rotation-symmetrical conical surface matched to the outer rotation-symmetrical surface of the shaft member;
- disposing an anaerobic adhesive on one of the rotation symmetrical surfaces;
- placing the hub member and the shaft member into a mutually engaged position thereby forming an intermediate space of a joint slot;
- pressing the hub member and the shaft member together in an axial direction thereby forcing the anaerobic adhesive into residual roughness present at the intermediate space of the joint slot adjoining the pressed-in rotation-symmetrical seat having an oversize thereby forming an integral joint between the shaft member and the hub member.
