G) Depending upon the pitch of the spline, the minimum chamfer on the major diameter may not clear the internal form diameter.
Internal splines made to the 19 standards had the same dimensions as shown for the major diameter fit splines in this standard.ī) For 15 teeth or less, the minor diameter of the internal spline, unless chamfered, will interfere with the form diameter of the external spline.Ĭ) For 9 teeth or less, the minor diameter of the internal spline, unless chamfered, will interfere with form diameter of the external spline.ĭ) The internal minor diameter, unless chamfered, will interfere with the external form diameter.Į) The internal minor diameter, unless chamfered, will interfere with the external form diameter.į) For 10 teeth or less, the minimum chamfer on the major diameter of the external spline may not clear the internal form diameter. They have a splined hub on one side and a keyed hub on the other. A) The external major diameter, unless chamfered or reduced, may interfere with the internal form diameter on flat root side fit splines. These couplings are commonly used to connect hydraulic pumps, compressors, and other heavy duty equipment, which often have splined shafts, to electric motors and other components that often have keyed shafts.
