For space widths of hubs and tooth thicknesses vin shafts, this standardprovides deviation series and tolerances based on the nominal dimensions, see figure 7. This standard specifies deviation series and tolerances for space widths of hubs and tooth thicknesses of shafts, which are based on the nominal dimensions, see Figure 7. The tolerance field for the root diameter of the tooth space is 9H. The entire contents of DIN See table 5 for recommended tolerance fields of the root circle and tip circle diameters.

Bottom clearance of flank-centred connections7. This series of standards has been revised by Technical Committee 2.

This is necessary because the fit sin created for all left and right flanks of all teeth. Eight tolerance grades are specified for hubs and shafts, determining the total tolerance as well as the actual and effective individual tolerances.

Table 8 gives guideline values for the radial runout of the pitch diameter of external splines relative to a reference axis.

DIN 5480-1 Splined connections with involute splines based …

These deviations reduce the clearance of spline joints so severely that provision must be made for this effect. In practice, the size of the actual tolerance Tact in relationship to the effective tolerance Teff within the total tolerance TG varies greatly.


Preferred series, reference diameters dB from 6 mm to 58 mm We have no document history for this standard. Subscription pricing is determined by: Need more than one copy?

Calculation of tolerance limits These are not interchangeable with involute splines as described by the DIN series of standards. The selection of nominal dimensions is essentially determinedby the following condition: The symbol z then represents the new odd number of spaces.

The nominal dimension of the centring diameters for diameter fit splines is the reference diameter in the case of major diameter fits and the hub tip diameter for minor diameter fits. Tools The new edition of DIN deals with fundamental principles, the same as its predecessor, but now also includes fit dimensions and tolerances, these being formerly contained in DIN For details, see DIN5.

Calculating spline connections according to DIN with diameter centering

The project provides data for the design of tools hobs, pinion type cutters, broaches for the manufacturing of splines according to DIN Nominal and inspection dimensions Part The DIN series of standards is based on reference diameters that are independent of the module, allowing an optimal fit to standard ball and roller bearing diameters and reducing the number of different tools required for manufacturing.

DIN Basic rack profileFigure 2 shows the basic rack profile. The deviation series permits 5480-166 definition of fit types interference, transition, clearance. The basic rack profile is the same for all pitches, therefore applying a uniform design rule to all profiles.

Internal diameter centring 16Uncontrolled copy when printed. The difference between the space width and the tooth thicknessdetermines the rotational backlash. It lays down the following general characteristics for splines as in this standard: The nominal dimensions of the centring diameters of diameter-centred connections are the referencediameters for ddin diameter centring or of the hub tip circle diameters for internal diameter centring.

In the case of flank-centered connections, the flanks are used for centering and rotational synchronization. For dated references, only the edition cited applies. The method of calculating the inspection dimensions over and between measuring circles from the dimensions of the space widths and the tooth thicknesses is described in DIN5. Nominal dimensions and inspection dimensions DINInvolute splines 55480-16 on reference diameters — Part DIN Figure 1: As analternative, this can also be done using the deviation factors as described in DIN The fit and the centring accuracy are determined by the deviations of the space widths and thicknesses as well as by the tolerances achieved or specified.
