the rolling members being guided in grooves in both coupling parts

Full Title

Yielding couplings, i.e. with means permitting movement between the connected parts during the drive > Universal joints in which flexibility is produced by means of pivots or sliding or rolling connecting parts > one coupling part entering a sleeve of the other coupling part and connected thereto by sliding or rolling members > the rolling members being balls, rollers, or the like, guided in grooves or sockets in both coupling parts > the rolling members being guided in grooves in both coupling parts

• F16D 3/2233 where the track is made up of two curves with a point of inflexion in between, i.e. S-track joints
• F16D 3/2237 where the grooves are composed of radii and adjoining straight lines, i.e. undercut free [UF] type joints
• F16D 3/224 the groove centre-lines of each coupling part lying on a sphere
• F16D 3/226 the groove centre-lines of each coupling part lying on a cylinder co-axial with the respective coupling part
• F16D 3/229 Prismatic coupling parts having each groove centre-line lying on planes parallel to the axis of the respective coupling part
