GB/T 10919-2021 Gauges for straight-sided splines
1 Scope
This document specifies the types and design principles, tolerances, requirements, verification methods, marking and packaging of the gauges for straight-sided splines used for verifying the straight-sided splines for cylindrical shafts with minor diameter centering.
This document is applicable to the design, production and use of the gauges for straight-sided splines used for verifying straight-sided splines specified in GB/T 1144-2001 (nominal minor diameter: 11 mm ~ 112 mm, nominal major diameter: 14 mm ~ 125 mm and spline width/spline space width: 3 mm ~ 18mm).
