External diameter centring 7.

Key1 djn hub3 profile reference line Figure 2: The fit and accuracy of concentricity are determined by the selected ISO tolerance fields of the centringdiameters. DIN Splined connections with involute splines based DIN Figure 1: The calculation formulae, tolerances and deviations contained in Part 1 also apply to the other parts di this series of standards.

Involute splines in accordance with ISO are based on series of modules. These deviations reduce the fit clearance of a fitted splined connection so severely that provision must be made for this reducing effect. 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 free. Published by Guset User DIN covers quality inspections of fitted splined connections.

DIN Table 1: This standard can also be applied, however, to design diameter-centred connections. The object of the revision was to combine the individual parts of this standard in a practical, useful and sensible manner.

They determine the design value of the connection diameter. In hubs, the superposition of all individual deviations leads to an effective space width that is smaller than the actual space that can be measured. For space widths of hubs and tooth thicknesses of shafts, this standardprovides deviation series and tolerances based on the nominal dimensions, see figure 7.


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

Given these values, it is the designer’s task to select the deviations and tolerance classes. Such connections mustalways be given enough backlash in order to prevent over-determination of the centring see figures 4 and 5. In practice, measuring balls or measuring pins are used as measuring circles.

Actual dim 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. For datedreferences, only the edition referred to applies to this standard. This series of standards has been revised by Technical Committee 2.

The machining-method-dependent root circle diameters of shafts created by 14Uncontrolled copy when printed. For a minimum fit clearance of zero, it isbetter to set the effective tolerance limits to the dimension of the nominal space width e2 and the nominal tooththickness s1.

For choosing the tooth numbers, the module, the type of centering and fitting, we are referring to the tables published by the various standardization organizations. There are six deviations, from F to M for hubs and 18 deviations from v to a for shafts. DIN Table 2: The entire series of standards now consists of only four parts instead of the previous sixteen. 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.


DIN Basic rack profileFigure 2 shows the basic rack profile. The increased use of spline connections with involute tooth flanks has brought us to purchase a wide variety of hobbing and tools and this is in accordance with the various standardization systems. Profile of the shaft The form of the slots as indicated above is closely linked to the finish method.

For undated references, the latest edition including all amendments of the publication referred to applies. This is necessary because the fit is created for all left and right flanks of all teeth.

Refer to table 5 for recommended tolerance fields and deviations of the root circle and tipcircle diameters. Refer to clause 10 for the relationship between space width tolerance and idn thickness tolerance, measurement methods, spline mesh quality and backlash. As analternative, this can also be done using the deviation 5840-1 as described in DIN Table 8 shows, as guide values, radial runouts of the referencecircle of external splines relative to a reference axis.
