Abstract
A spline-coupling structure in which at least one of male and female members has a press-fit guide face provided at its end opposed to the other member before press-fitting of the members. The press-fit guide face includes a plurality of guide face portions smoothly interconnecting the end and bottom lands of the spline teeth of the one member to form axially outwardly expanded arcs, a plurality of second guide face portions smoothly interconnecting tooth addendums of the spline teeth and the end to form axially outwardly expanded arcs, and a plurality of third guide face portions smoothly interconnecting tooth flanks of the spline teeth and the second guide face portion to form axially outwardly expanded arcs. The first, second and third guide face portions are connected smoothly to one another. Thus, dragging between the spline teeth of both members is prevented during press-fit coupling, to maximize the function of crownings to reduce press-fitting load and provide a sufficient coupling force, and facilitate disengagement of both members from each other and allow reuse of both members.
