AbolishedStraight cylindrical involute splines--30°pressurengle M and W values
圆柱直齿渐开线花键 30°压力角 M值和W值
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 30° pressure angle. It is applied in the design, manufacturing, and inspection of mechanical transmission systems, such as automotive drivetrains, machine tools, and aerospace components, to ensure correct gear tooth geometry and fit. Engineers and quality control personnel use these values to verify spline dimensions during production and assembly.
