If it is necessary to change dun size ratio, then the actual tolerances and the effective tolerances as stated in this standard can be selected separately from the different tolerance grades and will, when added, lead to a total tolerance deviating from this standard.

Even numbers of teeth have been given preference in tables 1 and 2. Where the teeth number is divisible, the centring surfaces can be widened by providing multiple teeth on the shaft and multiple spaces in the hub, for instance in order to make, with primarily lateral loading see DINdiameter fit spline joints stronger or to allow diameter fits for splines with a small module see Figure 1. The shaft cross-section remaining available for transmitting torques shall not be reduced more than is necessary to permit easy slip-fitting of components such as, for instance, ball or roller bearings.

For limits of centring accuracy, see DIN The manufacturing tolerance should be rin least twice the expected tooth thickness variation 5840-16. DIN Validity Sin standard is valid from onwards.

Involute splines based on reference diameters – Part 16: Tools

Diameter-centred connections necessitate greater manufacturing effort due to the small tolerances of thecentring diameters and the measures required to limit the offsets between the centring diameter centre andthe centre of the tooth circle. This series of standards has been revised by Technical Committee 2. This series of standards has been 5480-1 by Technical Committee 2.

The full root dkn has been included for shafts. For datedreferences, only the edition referred to applies to this standard. The designations given inDIN for gear teeth are also permitted.

If the document is revised or amended, you will be notified by email. The symbol z then represents the new odd number of spaces. It is notpossible to state standard values for this. See table 5 for recommended tolerance fields of the 5480-166 circle and tip circle diameters. The tolerance field for the root diameter of the tooth space is 9H.

In the tables of dimensions given in DINonly the absolute values ofdiameters and inspection dimensions are listed, i. Such spline joints shall always be given enough backlash in order to prevent over-determination of the centring see Figures 4 and 5.

DIN now contains the nominal dimensions and inspection dimensions for the range of items stated above. Refer to Table 5 for recommended tolerance fields for the root and tip diameters. The flanks of the teeth are subject to individual deviations from the profile, the flank line and the pitch.

These should therefore only be used in a few exceptional cases. Double teethIf the number of spaces which can measured using pins is an odd number, then the measurements given inthe tables can be converted. Tools The new edition of DIN deals with fundamental principles, don same as its predecessor, but now also includes fit dimensions and tolerances, these being formerly contained in DIN Diameter fit splines require greater manufacturing effort due to the small tolerances of the centring diameters and the measures required to limit the offsets between the centring diameter centre and the centre of the tooth circle.

For limits of centring accuracy, see DIN Bottom clearance of flank-centred connections The corresponding descriptive parameters, tooth interlock data and calculation formulae are given in Table dij. DIN Table 6: For a minimum fit clearance of zero, it isbetter to set the effective tolerance limits to the dimension of the nominal space width e2 and the nominal tooththickness s1.

DINan N for a hub or W for a shaft, followed by an A for externally-centred connections or an I forinternally-centred connections only in the case of diameter-centred connectionsthen by the module, thenumber of teeth, the tolerance class and the deviation series. This means that the respective workpiecesmay not be rejected because of individual deviations.

The tolerance band calculated for the root diameter is also used here.
