Involute splines based on reference diameters - Part 2: Nominal and inspection dimensions
Involute spline shafts manufactured to this standard are used for clearance, sliding and interference connections of shafts and hubs. They contain all characteristics for the transmission of torque, the location and an economic production.*This series of standards deals with involute splines and spline joints within a module range of 0,5 to 10, having a number of teeth ranging from 6 to 82 and with a pressure angle of 30°. The DIN 5480 series of standards is limited to splines with a pressure angle of 30°, since pressure angles of 37,5° and 45° are covered by ISO 4156. Involute splines in accordance with ISO 4156 are based on module series. These are not interchangeable with involute splines conforming to the DIN 5480 series of standards. The DIN 5480 series of standards is based on reference diameters that are independent of the module, allowing an optimal fit to standard ball and roller bearing diameters and reducing the number of different tools required for manufacturing. This series of standards has been revised by Technical Committee 2.1 Passverzahnungen ("Involute splines") of the Mechanical Engineering Standards Committee. The revision was considered necessary since a review of the DIN 5480 series of standards in accordance with DIN 820-4 had shown that the series had structural and editorial weaknesses. The object of the revision was to combine the individual parts of this standard in a practical, sensible manner. The entire series of standards now consists of only four parts instead of the previous sixteen. DIN 5480 Involute splines based on reference diameters now comprises: - Part 1: General - Part 2: Nominal and inspection dimensions - Part 15: Inspection - Part 16: Tools. The new editionof DIN 5480-1 deals with fundamental principles, the same as its predecessor, but now also includes fit dimensions and tolerances, these being formerly contained in DIN 5480-14:1986-03. The calculation formulae, tolerances and deviations contained in Part 1 also apply to the other parts of this series of standards. DIN 5480-2 now contains the nominal dimensions and inspection dimensions for the range of items stated above, and incorporates the contents of the former editions of DIN 5480-2 to DIN 5480-13. DIN 5480-15 covers quality inspections of spline joints. DIN 5480-16 defines the design features of tools for manufacturing involute splines. This standard differs from DIN 5480-1:1991-10 and DIN 5480-14:1986-03 as follows: a) The title has been changed to "Involute splines based on reference diameters". b) The full root radius has been included for shafts. c) Cold-rolling has been included as a manufacturing process for shafts. d) The standard has been editorially revised.
