Application Summary AI generated

This standard specifies the M (span measurement over pins) and W (span measurement over teeth) values for straight cylindrical involute splines with a 45° pressure angle. It is applied in the design, manufacturing, and inspection of mechanical transmission systems, particularly in automotive, aerospace, and industrial machinery where precise spline fit and load distribution are critical. The standard ensures consistent measurement methods for quality control and interchangeability of splined components.
