The fit and accuracy of concentricity are determined by the selected ISO tolerance fields of the centringdiameters. 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.

DIN also contains formulae for calculating dim exact root circle diameters of shafts with cold-rolled splines. Recommended tolerances and deviations for tip and root circle diameters Certain systems are even equipped to use the same milling tools as for normal teeth. The deviation seriespermits the definition of free fits, transitions fits and interference fits.

Create your own flipbook. If very many measurements are taken in different angular positions and measuring planes, it may be useful to apply statistical concepts dih evaluating the actual tolerance limit.

Internal and external spline teeth

Example of a data field in a drawing The tolerances are depending on mounting conditions, shaft I z or tooth flank centering F z. Eight tolerance classes are available for the magnitude of the overall tolerances of hubs and shafts. DIN Table 3: DIN Data to be shown on drawings9.

For datedreferences, only the edition referred to applies to this standard. If a GO gauge does fit, this will in all caseseffectively ensure adherence to the tolerance limit. This standard can also be applied, however, to design diameter-centred connections. A number of teeth expressed as 6 12 indicates six double teeth out of a total of 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.

This applies both to spline connections with involute flanks as for spline connections with straight flanks. If it becomes necessary to change the size ratio, then the actual tolerances 5840-1 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.

Calculation of tolerance limitsSpace width max. This is necessary because the fit is created for all left and right flanks of all teeth. For choosing rin number of keys depending on the diameters and of the load, 5480–1 also for indicating the tolerances according to the desired fit loose, sliding, straining we refer to the tables published by the various standardization organizations: A designfit clearance of zero ensures that the hub can be fitted on the shaft.

DIN For further information, we refer to the relevant standard.

The difference between the space dni and the tooth thicknessdetermines the rotational backlash. The tolerance classes define themanufacturing tolerances.

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

View in Fullscreen Report. The selection of nominal dimensions is essentially determinedby the following condition: DIN Table 2: These are not interchangeable with involute splines as described by the DIN series of standards. DIN can be selected individually for hubs and shafts as shown in table 9.

They determine the magnitude of the overall tolerance as well as the actual and effective individual tolerances. It istherefore recommended that these be indicated in the form of a data field, see figure 6. Bierens at Tilburg NL.
