The flanks of the teeth are used both for transmitting the torque and for centring the hub and shaft relative to one another.

All reference profiles without the note Major diameter fit or Minor diameter fit are for flank-centered splined joints. In shafts, the superposition of all individual deviations lead to an effective tooth thickness that is greater than the actual thickness which can be measured.

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. For dated references, only the edition cited applies. 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.

Where necessary, the data for the statistical actual tolerance 548-16 STA are to be entered at the 5480-116 of the data field.

DIN 5480-16

Since it is difficult to measure tooth thickness and space widths directly, they shall be converted to dimensions across and between 54480-16 circles and are entered in this form into the data field.


The total tolerance combines the actual tolerance and the effective tolerance. The tolerance band calculated for the root diameter is also used here. The manufacturing tolerance should be at least twice the expected tooth thickness variation Rs.

Standard – Involute splines based on reference diameters – Part Tools DIN –

A designfit clearance of zero ensures that the hub can be fitted on the shaft. This series of standards has been revised by Technical Committee 2. This series of standards has been revised by Technical Committee 2. Compliance with the effective tolerance limit is checked usingfully-splined GO gauges.

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. Standards Subsctiption may be the perfect solution. DIN now contains the nominal dimensions and inspection dimensions for the range of items stated above, and incorporates the contents of the former editions of DIN to DIN In practice, the size of the actual tolerance Tact vin relationship to the effective tolerance Teff within the total tolerance TG varies greatly.

The teeth merely serve to transmit the forces. Refer to Table 5 for recommended tolerance fields for the root and tip diameters.

Refer to table 5 54800-16 recommended tolerance fields and deviations of the root circle and tipcircle diameters. DIN Splined connections with involute splines based on reference diameters now comprises: If either the reference diameter or the module lie outside of the defined range, the adjacent edge value in the table is used as cFmin.


Figure1 shows an externally-centred shaft with splines. In the Tables of dimensions given in DINonly the absolute values of diameters and inspection dimensions are given, i.

These have a predefined interrelationship. The project provides data for the design of tools hobs, pinion type cutters, broaches for the manufacturing of splines according to DIN The symbol z then represents the new odd number of spaces.

The overall tolerance combines the actual tolerance and the effective tolerance. The flanks of the teeth are subject to individual deviations due to the profile, the helix and the pitch. The tip and root diameters of the shaft differ from the respective diameters of the hub by at least the bottom clearance c see Figure 3. They determine the design value of the connection diameter. This is necessary because the fit is created for all left and right flanks of all teeth.

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 dln. The specified range of fundamental deviations and tolerance classes takes due consideration of all requirements.
