ActiveStraight cylindrical involute splines - Metric module, side fit - Part 8: 45°pressure angle M and W values
圆柱直齿渐开线花键 （米制模数 齿侧配合） 第8部分：45°压力角 M值和W值
Application Summary AI generated
This standard specifies the M values (measurements over pins) and W values (measurements over teeth) for straight cylindrical involute splines with a 45° pressure angle and metric module side fit. It is applied in the design, manufacturing, and quality inspection of mechanical transmission systems, particularly in automotive, aerospace, and industrial machinery where precise spline dimension verification is required for proper fit and load distribution.
