Double teethIf the 54480-1 of spaces which can measured using pins is an odd number, then the measurements given inthe tables can be converted. Example of a data field in a drawingIf the method of measurement has to be specified, it is also possible to state a measuring ball or measuringpin diameter instead of the measuring circle diameter.

In the data field of the fin drawing, it is given as the actual tolerance limit and as the reference mark actual Ref. This standard can also be applied, however, to design diameter-centred connections. DIN Data to be shown on drawings9. Bierens at Tilburg NL. Key1 shaft2 hub3 profile reference line Figure 2: The object of the revision was to combine the individual parts of this standard in a practical, useful and sensible manner.

Preferred series, reference diameters dB from 6 mm to 58 mm Recommended tolerances and deviations for tip and root circle diameters There are six deviations, from F to M for hubs and 18 deviations from v to a for shafts. Hereafter, we present the characteristics of the main spline connections.


B DIN — B 6x28x32 Spline connections with dln flanks The increased use of spline connections with involute tooth flanks has brought us to purchase a wide variety of hobbing and tools and this is in accordance with the various standardization systems. This means that the respective workpiecesmay not be rejected because of individual deviations.

It dun recommended that these be indicated in the form of a data field, see ein 6.

DIN Splined connections with involute splines based

Spline connections with straight flanks: For datedreferences, only the edition referred to applies to this standard. Figure1 shows an externally-centred shaft with splines. These values do not constitute a tolerance, but are used to track down the causeof nonconformities in cases where GO gauges will not fit. If it becomes necessary to change the size ratio, then the actual tolerances and the effective tolerances as stated in this standard can be selected separately from the different tolerance classes and will, when added, lead to an overall tolerance deviating from this standard.

If a GO gauge does fit, this will in all caseseffectively ensure adherence to the tolerance limit.

DIN Splined connections with involute splines based The fit and accuracy of concentricity are determined by the selected ISO tolerance fields of the centringdiameters. These lead to negative signs for all hub diametersand dimensions see DIN In practice, the size of the actual tolerance Tact in relationship dij the effective tolerance Teff within the overall tolerance TG varies very strongly.


The magnitudes of the deviations are identified by upper-case characters and 21Uncontrolled copy when printed DIN can be selected individually for hubs and shafts as shown in table 9. DIN Table 5: The deviations Ae and As as well as the tolerances Tact and Teff of the tolerance class are selected as shown in table 7.

DIN also contains formulae for calculating the exact root circle diameters of shafts with cold-rolled splines. Such connections mustalways be given enough backlash in order to prevent over-determination of the centring see figures 4 and 5.

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. 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.

DIN Addendum modification nave x 1. The dimension over or between measuring circles isthen stated either djn the dimension over or between balls or pins, accordingly. DIN Table 1: Actual tolerance limits are checked with the aid of the auxiliary dimensions acrossand between measuring circles using measuring balls or pinsor alternatively using sector NOT GO gauges.
