Straight cylindrical involute splines -- Metric module, side fit -- Part 2: Dimensions
This standard was last reviewed and confirmed in 2015. Therefore this version remains current.
ISO 4156-2:2005 specifies geometry and inspection dimensions for the design and manufacture of straight (non-helical) side-fitting cylindrical involute splines.
The specified diameters for external splines in the geometry tables and the values in the inspection dimension tables are only valid for fundamental deviation h.
For fundamental deviations other than h, diameters and tooth thicknesses are calculated for external splines according to the formulae in ISO 4156-1:2005 and inspection dimensions according to the formulae in ISO 4156-3:2005.
