GB/T 10081-1988

This standard specifies the preferred length series for straight-sided internal splines, providing a range of standardized lengths to ensure interchangeability and compatibility in mechanical assemblies. It is applied in the design and manufacturing of mechanical transmission systems, such as automotive drivetrains, machine tools, and industrial gearboxes, where splined shafts and hubs must mate precisely. The standard is used by engineers and procurement professionals to select appropriate spline lengths for production and quality control.
