摘要：In pressure forming splines or teeth in the axially-extending sleeve of a clutchhub having a cylindrical oil seal surface adjacent the sleeve, a pair of special tooth-forming racks adapted to intermesh with a toothed mandrel with the sleeve

therebetween and a pair of special support racks adapted to contact the oil seal surfaceare used. Each tooth-forming rack includes a first working surface with a plurality oftoothed sections interrupted and spaced apart by toothless sections in an alternatingsequence and each further includes a second working surface with uninterrupted toothedsections. Each support rack includes a first working surface with raised support sectionsinterrupted and spaced apart by lower non-supporting sections in a proper alternatingsequence and configuration to insure that the raised sections support the oil seal surfacewhen the interrupted toothed rack sections of the tooth-forming racks deform thesleeve. A second working surface of the support racks includes a raised support sectionsimilarly adapted to support the oil seal surface during initial contact of theuninterrupted rack teeth of the tooth-forming racks with the sleeve. A clutch hub isthereby manufactured having a splined sleeve roundness within 0.025 inch and oil sealsurface roundness within 0.006 inch.
