3 Validity This standard is valid from Foreword This series of standards deals with involute splines and spline joints within a module range of 0,5 to 10, having a number of 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 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 s that are independent of the module, allowing an optimal fit to standard ball and roller bearing s 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 Normenauschuss Maschinenbau (Mechanical Engineering Standards Committee). The revision was considered necessary since a review of the DIN 5480 series of standards in accordance with DIN 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 s now comprises: Part 1: General Part 2: and inspection s Part 15: Inspection Part 16: Tools The new edition of DIN deals with fundamental principles, the same as its predecessor, but now also includes fit s and tolerances, these being formerly contained in DIN : The calculation formulae, tolerances and deviations contained in Part 1 also apply to the other parts of this series of standards. DIN now contains the nominal s and inspection s for the range of items stated above, and incorporates the contents of the former editions of DIN to DIN DIN covers quality inspections of spline joints. DIN defines the design features of tools for manufacturing involute splines. 3

5 1 Scope This standard applies to involute splines and spline joints based on reference s for connecting hubs and shafts either with a removable connection, a sliding fit or a permanent fit. It lays down the following general characteristics for splines as in this standard: a) They have a standard pressure angle of 30. b) The basic rack profile is the same for all pitches, therefore applying a uniform design rule to all profiles. c) They have a side fit profile (a fit is permitted in some cases). d) Addendum modification is used in order to achieve specific reference s. e) The fit system includes tolerances for effective form deviations so that the effect of such deviations on backlash is taken into account. The specified range of fundamental deviations and tolerance classes takes due consideration of all requirements. Involute spine joints as in this standard are used for connecting hubs and shafts either with a removable connection, a sliding fit or a permanent fit. They have all the characteristics required for centring the parts and transmitting torques, as well as meeting all the requirements for economical manufacturing. The theoretical root s for hubs and shafts where the dedendum of the basic rack profile, h fp, is 0,55 m. The dedendum depends on the manufacturing method used, and can therefore have various values (see DIN , Table 3). The root s depend on the dedendum. 2 Normative references The following referenced documents are indispensable for the application of this document.
