Given these values, it is the designer’s task to select the deviations and tolerance classes. Bottom clearance of flank-centred connections7.

Calculation of tolerance limitsSpace width max. 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. This standard can also be applied, however, to design splines with a diameter fit. A number of teeth expressed as 6 12 indicates six double teeth out of a total of This means that the respective workpiecesmay not be rejected because of individual deviations.

These values do not constitute a tolerance, but can be used to determine the cause of nonconformities in cases where GO gauges will not fit. DIN defines the design features of tools for manufacturing items with involute splines.

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.

The exact root circle diameters of hubs and shafts with splines created by rolling are calculated using theformulae given in DINtaking into account the particular features of the respective rolling method, thedeviations of the space widths and tooth thicknesses and, where necessary, a machining addition. The teeth merely serve to transmit the forces. The tolerance band calculated for the root diameter is also used here.

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. Such connections mustalways be given enough backlash in order to prevent over-determination of the centring see figures 4 and 5.

DIN – European Standards

The basic rack profile is the same for all pitches, therefore applying a uniform design rule to all profiles. These determine the design dimension of the spline diameters where the chip-cutting manufacturing method is not yet known and the tool run-out spaces are free. The flanks of the teeth are subject to individual deviations from the profile, the flank line and the pitch.

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. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

540-16 following values apply for flank-centered splines: As an alternative, this can also be done using the deviation factors as described in DIN DIN covers quality inspections of spline joints. When the root circle tolerances are calculated according to the basic standard DIN table 5the root form diameter is calculated as specified by the formulae on page The number of teeth shall be selected in such a way that the addendum modification necessitated by the reference diameter is kept within the range x1?

Eight tolerance grades are specified for hubs and shafts, determining the total tolerance as well as the actual and effective individual tolerances.

The flanks of the teeth are used both for transmitting the torque and for centring the hub and shaft relative to one another. DIN Table 6: The full root radius has been included for shafts. The tolerance classes define the manufacturing tolerances. The magnitudes ein 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.

For dated references, only the vin cited applies. DIN Basic rack profileFigure 2 shows the basic rack profile. Root diameters of shafts with cold-rolled splines are calculated by subtracting 0,58?

The deviations Ae and As as well as the tolerances Tact and Teff for the relevant tolerance grade are to be taken from Table 7. These deviations reduce the fit clearance of a fitted splined connection so severely that provision must be made for this reducing effect.

The symbol z then represents the new odd number of spaces. The flanks of the teeth are used both for transmitting the torque and for centring the hub and shaft relative to one another. 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. The entire series of standards now consists of only four parts instead of the previous sixteen.

The object of the revision was to combine the individual parts of this standard in a practical, sensible manner. If the document is revised or amended, you will be notified by email.

The standard has been editorially revised. All reference profiles without the note Major diameter fit or Minor diameter fit are for flank-centered splined joints. In practice, the size of the actual tolerance Tact in relationship to the effective tolerance 54801-6 within the total tolerance TG varies greatly.
