The calculation formulae, tolerances and deviations contained in Part 1 also apply xin the other parts of this series of standards.

In connections centred on any reference diameter, this condition is met by making the referencediameter equal to the bore of the bearing and then modifying the profiles of the teeth of the hub and the shaftaccordingly. These determine the design dimension of the connection diameters where the chip-cutting manufacturing method is not yet known and the tool run-out spaces are free.

The intention which is the basis of this idea is: DIN Addendum modification nave x 1. In the tables of dimensions given in DINonly the absolute values ofdiameters and inspection dimensions are listed, i. Grundlagen Supersedes DIN In practice, the size of the actual tolerance 54480-1 in relationship to the effective tolerance Teff within dun overall tolerance TG varies very strongly.

The property defining the fit is the fit of the flanks, the backlash.

If very many measurements are taken in different angular positions and measuring planes, it may be useful to apply statistical concepts when evaluating the actual tolerance limit. Dib connections necessitate greater manufacturing effort due to the small tolerances of thecentring diameters and the measures required to limit the offsets dkn the centring diameter centre andthe centre of the tooth circle. The deviations Ae and As as well as the tolerances Tact and Teff of the tolerance class are selected as shown in table 7.

This is necessary because the 54801 is created for all left and right flanks of all teeth. DIN covers quality inspections of fitted splined connections. The reasons for this are explained insubclause 7. The method of calculating the inspection dimensions over and between measuring circles from thedimensions of the space widths and the tooth thicknesses is described in DIN5.

In the case of numbers of teeth which 5480-11 not prime numbers, the centring surfaces can be widened bymultiple teeth on the shaft and multiple spaces in the hub, for instance in order to make diameter-centredconnections stronger or to allow diameter centring with small modules see figure 1.

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.

It is notpossible to state standard values for this.

Compliance with the effective tolerance limit is checked usingfully-splined GO gauges. DIN Validity This standard is valid from onwards.

The dimension over or between measuring circles isthen stated either as the dimension over or between balls or pins, accordingly. Even numbers of teeth have been given preference in tables 1 and 2.

The revision was considered necessary since a review of the DIN series of standards in accordance with DIN had shown that the series had structural and editorial weaknesses. Given these values, it is the designer’s task to select the deviations and tolerance classes.
