They determine the design value of the connection diameter. For diameter-centring, the tolerance class andthe deviation series are placed in front of the respective data of the tooth flanks.

This is necessary because the fit is created for all left and right flanks of all teeth.

The intention which is the basis of this idea is: Read the Text Version. Compliance with the effective tolerance limit is checked usingfully-splined GO gauges.

Tools The new edition of DIN deals with fundamental principles, the same as its predecessor, 54480-1 now also includes fit dimensions and tolerances, these being formerly contained in DIN DIN covers quality inspections of fitted splined connections.

The deviation seriespermits the definition 5408-1 free fits, transitions fits and interference fits. 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.

DIN also contains formulae for dib the exact root circle diameters of shafts with cold-rolled splines.

Deviations and tolerances Reference diameters Modules Example: Here are the formulas for the calculation of different ddin. In practice, the size of the actual tolerance Tact in relationship to the effective tolerance Teff within the overall tolerance TG varies very strongly.

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. The reasons for this are explained insubclause 7. The manufacturing tolerance should be at least twice the expected tooth thickness variation Rs. The magnitudes of 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 datedreferences, only the edition referred to applies to this standard.

Hereafter, we present the characteristics of the main spline connections. The diameters of the tip and root circles of the shaft differ from the respective diameters of the hub by at least the bottom clearance c see figure 3.

The flanks of the teeth rin used both for transmitting the torque and for centring the hub and shaft relative to one another. Published by Guset User A designfit clearance of zero ensures that the hub can be fitted on the shaft. The tolerances are depending on mounting conditions, shaft I z or tooth flank centering F z.

The deviations Ae and As as well as the tolerances Tact and Teff of the tolerance class are selected as shown in table 7. It istherefore recommended that these be djn in the form of a data field, see figure 6. The symbol z then represents thenew odd number of spaces.

DIN Table 2: Guide values for radial runout Amendments This standard differs from the DIN The difference between the space width and the tooth thicknessdetermines the rotational backlash. These values do not constitute a tolerance, but are used to track down the causeof nonconformities in cases where GO gauges will not fit.

For a minimum fit clearance of 4580-1, it isbetter to set the effective tolerance limits to the dimension of the nominal space width e2 and the nominal tooththickness s1.
