Standard – Involute splines based on reference diameters – Part Tools DIN –
For limits of centring accuracy, see DIN Principles Passverzahnungen mit Evolventenflanken und Bezugsdurchmesser — Teil 1: Table 4 — Minimum dinn clearance Minimum form clearance cFmin? The designations given in DIN for gear teeth are also permitted. When created by hobbing they can be calculated by subtracting 0,1?
The calculation formulae, tolerances and deviations contained in Part 1 also apply to the other parts of this series of standards.

These deviations reduce the fit clearance of a fitted splined connection so severely that provision must be made for this reducing effect.
Ae and TG in series 9H see 7. As the voice of the U. The teeth merely serve to transmit the forces. 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.
Table 8 shows, as guide values, radial runouts of the referencecircle dim external splines relative to a reference axis.
The fit and centring accuracy are determined by deviation in space width and tooth thickness, and by the tolerances achieved or specified. The magnitudes of the deviations are identified by upper-case characters and 21Uncontrolled copy when printed.
The tip and root diameters of the shaft differ from the respective diameters of the hub by at least the bottom clearance c see Figure 3. DIN Table 2: Preferred series, reference diameters dB from 60 mm to mm 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 details, see DIN5. The entire series of standards now consists of only four parts instead of the previous sixteen.
The tolerance band calculated for the root diameter is also used here. The root diameters of shafts are dependent on the machining method used: In practice, the size of the actual tolerance Tact in relationship to the effective tolerance Teff within the overall tolerance TG varies very strongly.
External diameter centring 7. In the case of numbers 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.
The corresponding descriptive parameters, tooth interlock data and calculation formulae are given in Table 3. This standard is not included in any packages. The tolerance classes define themanufacturing tolerances. The deviations for hubs are designated by upper case letters and those for shafts are designated by lower case letters; see Table 9.
The following values apply for flank-centered splines: Figure 3 — Bottom clearance of side-fit splines 7. The flanks of the teeth are subject to individual deviations due to the profile, the helix and the pitch.
The flanks of the teeth are used both 55480-16 transmitting the torque and for centring the hub and shaft relative to one another.
Addendum modification is used in order to achieve specific reference diameters. If the document is revised or amended, you will be notified by email. The number of teeth shall be selected in such a way that the addendum modification necessitated 55480-16 the reference diameter is kept within the range x1? These deviations reduce the clearance of spline joints so severely that provision must be made for this effect.
This don can also be applied, however, to design splines with a diameter fit.
Example of a data field in a drawingIf the method of measurement has to be specified, it is also possible to state a measuring ball or measuringpin diameter instead of the measuring circle diameter. This standard is also available to be included in Standards Subscriptions. This avoids excessive reject rates, which would not occur if fewer measurements were to be taken.
Recommended tolerances and deviations for tip and root circle diameters 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. Basic rack profile 12Uncontrolled copy when printed. Please first log in with a verified email before subscribing to alerts. There are six deviations, from F to M for hubs and 18 deviations from v to a for shafts.
We have no document history for this standard. This is necessary because the fit is generated over all left and right flanks of all teeth.
For diameter fit splines, the tolerance class dun fundamental deviation shall be placed in front of the respective data of the tooth flanks. These values do not constitute a tolerance, but can be used to determine the cause of nonconformities in cases where GO gauges will diin fit.
