The document you are looking for is the ANSI B92.1-1996 standard, titled "Involute Splines and Inspection" master2000.ru Document Overview
Interchangeability: The internal minimum effective space width and external maximum effective tooth thickness are consistent across all tolerance classes. Fit Types:
This standard provides the design data, tolerances, and inspection requirements for involute splines with pressure angles of 30°, 37.5°, and 45°
ConclusionThe ANSI B92.1-1996 standard is an essential technical resource for mechanical designers and manufacturers. By providing clear guidelines on tooth geometry, tolerance classes, and inspection methods, it enables the reliable production of high-strength, self-centering involute splines. Its emphasis on effective fit and interchangeability makes it a fundamental tool in ensuring the quality and functionality of splined connections in heavy-duty machinery. References
