Internal and external serrations. Dimensions and tolerances

This standard defines the fundamental dimensions and tolerance specifications for internal and external splined connections. It establishes a comprehensive framework for ensuring interchangeability and proper functioning of splined components across various mechanical applications. The document outlines precise geometric parameters, including tooth profiles, pitch diameters, and keyway configurations, which are critical for the manufacturing and quality control processes. By specifying allowable deviations, it facilitates the production of compatible parts that can be assembled without additional fitting or adjustment. The guidelines provided within this publication support the design of transmission systems and other mechanical assemblies where torque transmission and rotational alignment are essential. It serves as a technical reference for engineers and manufacturers involved in the development of machinery components, ensuring consistency and reliability in the final products. The scope covers both metric and other relevant sizing conventions applicable to splined joints, providing clear definitions for measurement methods and acceptance criteria.
