The DIN series of standards is based on reference diameters that are independent of the module. March DIN Splined connections with involute splines based on dinn diameters — Part 1: These deviations reduce the fit clearance of a fitted splined connection so severely that provision must be made for this reducing effect.

See table 5 for recommended tolerance fields of the root circle and tip circle diameters.

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

Read the Text Version. Here are the formulas for the 55480-1 of different diameters. It istherefore recommended that these be indicated in the form of a data field, see figure 6. For datedreferences, only the edition referred to applies to this standard. Calculation of tolerance limitsSpace width max. The manufacturing tolerance should be at least twice the expected tooth thickness variation Rs. B DIN — B 6x28x32 Spline connections with involute flanks 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.

Principles Passverzahnungen mit Evolventenflanken und However, in thiscase a note must be added stating that the GO gauge has priority.

For space widths of hubs and tooth thicknesses of shafts, this standardprovides deviation series and tolerances based on the nominal dimensions, see figure 7. As analternative, this can also be done using the deviation factors as described in DIN DIN Table 2: 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.

In practice, the size of the actual tolerance Tact in relationship to the effective tolerance Teff within the overall tolerance TG varies very strongly.

Actual tolerance limits are checked with the aid of the auxiliary dimensions acrossand between measuring circles using measuring balls or pins 54480-1, or alternatively using sector NOT GO gauges. Key1 shaft2 hub3 profile reference line Figure 2: Grundlagen Supersedes DIN Profile of the nave B: The flanks of the teeth are used both for transmitting the torque and for centring the hub and shaft relative to one another.

DIN Splined connections with involute splines based on reference diameters now comprises: Table 8 shows, as guide values, radial runouts of the referencecircle of external splines relative to a reference axis. The dimensions and modules in brackets are avoidable values. Dij successful synthesis of IT and mechanics: For undated dun, the latest edition including all amendments of the publication referred to applies.

DIN Addendum modification nave x 1. The flanks of the teeth are subject to individual deviations from the profile, the flank line and the pitch. The tolerances are xin on mounting conditions, shaft I z or tooth flank centering F z.

This makes it possible to adapt the gears to standardized ball and roller bearing diameters and to reduce the number of different tools required for manufacturing. The difference between the space width and the tooth thicknessdetermines the rotational backlash. Where necessary, the data for the statistical actual tolerance limit STA are entered at 5480- bottom of the data field of the fitted splined connection. Diameter-centred connections necessitate greater manufacturing effort due to the small tolerances of thecentring diameters and the measures required to limit the offsets between the centring diameter centre andthe centre of the tooth circle.


The tolerance classes define themanufacturing tolerances. 548-01 designfit clearance of zero ensures that 540-1 hub can be fitted on the shaft. These have predefined relationships to one another. This is necessary because the fit is created for all left and right flanks of all teeth.

Dib it is difficult to measure tooth thickness and space widths directly, they are converted to dimensions across and between measuring circles and are entered in this form into the data field.

The following is the table of normalized dimensions according to DIN Such connections mustalways be given enough backlash in order to prevent over-determination of the centring see figures 4 and 5. The object of the revision was to combine the individual parts of this standard in a practical, useful and sensible manner.

In the tables of 5840-1 given in DINonly the absolute values ofdiameters and inspection dimensions are listed, i.
