Unlike standard gears, spline teeth are generally cut shallower (often half the depth of a standard gear tooth). Academia.edu 2. Core Technical Specifications
ANSI B92.1 defines tooth sizing using a fraction system known as , denoted as (e.g., 8/16, 10/20, 16/32): ANSI B92.1-1996 - INVOLUTE SPLINES AND INSPECTION ansi b 92.1 pdf 38
) : The theoretical diameter where the tooth thickness equals the space width. : The diameter from which the involute curve is generated. Major Diameter ( Docap D sub o ) : The outside diameter of the external spline. Minor Diameter ( Dicap D sub i ) : The root diameter of the internal spline. 3. Circular Tooth Thickness and Space Width Unlike standard gears, spline teeth are generally cut
Involute Splines and Inspection (formerly ANSI B92.1-1970, re-affirmed 1993, and updated in 1996). : The diameter from which the involute curve is generated
Flat root side fit, fillet root side fit, and major diameter fit. Locating "38" in the Standard Context
Able to handle higher torsional loads than traditional keys. Finding the Standard (ANSI B92.1 PDF)
Deleting the term "involute serration," incorporating 45-degree splines into the main standard. 2. Key Components of ANSI B92.1
