Nominal dimensions and inspection 5480-1 DINInvolute splines based on reference diameters — Part For diameter fit splines, the tolerance class and fundamental deviation shall be placed in front of the respective data of the tooth flanks. Double teethIf the number of spaces which can measured using pins is an dinn number, then the measurements given inthe tables can be converted.
Involute splines in accordance with ISO are based on module series. The minimum form clearance cFmin values given in Table 4 provide an adequate excess length of the root involute so that disturbance-free contact between the involute flanks of the hub and shaft is ensured even when there are eccentricities in the motion of the interacting tip circle.
The definitive fit parameter is that for the flanks, the backlash. 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.
Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. The fit system includes tolerances for effective form deviations so that the effect of such deviations on backlash is taken into account.

Refer to table 5 for recommended tolerance fields of the root circle and tip circle diameters. These have predefined relationships to one another.
It is notpossible to state standard values for this. If a GO gauge does fit, this will in effect ensure adherence to the tolerance limit. 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 corresponding descriptive parameters, tooth interlock data andcalculation formulae are given in table 3. There are six deviations, from F to M for hubs and 18 deviations from v to a for shafts. Involute splines in accordance with ISO are based on series of modules. Uncontrolled copy when printed.

5480-61 Need more than one copy? DIN now contains the nominal dimensions and 5480-1 dimensions for the range of items stated above, and incorporates the contents of the former editions of DIN to DIN DIN Splined connections with involute splines based The reasons for this are explained in subclause 7. The deviations Ae and As as well as the tolerances Tact and Teff of the tolerance class are selected as shown in table 7.
Where the teeth number is divisible, the centring surfaces can be widened by providing multiple teeth on the shaft and multiple spaces in the hub, for instance in order to make, with primarily lateral loading see DINdiameter fit spline joints stronger or to allow diameter fits for splines with a small module see Figure 1. The project provides data for the design of tools hobs, pinion type cutters, broaches for the manufacturing of splines according to DIN The flanks of the teeth are subject to individual deviations due to the profile, the helix and the pitch.
Your Alert Profile lists the documents that will be monitored.
Grundlagen Supersedes DIN DINan N for a hub or W for a shaft, followed by an A for major diameter fit or an I for minor diameter fit only in the case of diameter fittingthen by the reference diameter, the module, the number of teeth, the tolerance class and the fundamental deviation.
This is necessary because the fit is created for all left and right flanks of all teeth. In the case of 5480-116 of teeth which are 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.

Actual tolerance limits shall be checked with the aid of the auxiliary dimensions over and between measuring circles using measuring 54480-16 or pinsor alternatively using sector NO GO gauges. Eight tolerance grades are specified for hubs and shafts, determining the total tolerance as well as the actual and effective individual tolerances.
