Iso 4156-1 Pdf

ISO 4156 primarily governs "side fit" splines. In this configuration, the contact occurs on the flanks of the teeth, leaving a clearance at the major and minor diameters. This is distinct from older "major diameter fit" designs. ISO 4156-1 provides the inspection criteria to ensure that the flank contact is optimal for torque transmission without interference at the roots or crests.

But for a spline to work efficiently—without backlash, stress fractures, or premature wear—it must be manufactured to exacting standards. That standard is , titled "Straight cylindrical involute splines — Metric module, side fit — Part 1: Generalities and definitions." iso 4156-1 pdf

The heart of the document is the massive data tables. For a given nominal size (e.g., module 2 mm, 30 teeth), the PDF provides: ISO 4156 primarily governs "side fit" splines
