Amendments This standard differs from the DIN A designfit clearance of zero ensures that the hub can be fitted on the shaft.

Internal and external spline teeth

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.

The deviations Ae and As as well as the tolerances Tact and Teff of the tolerance class are selected as shown in table 7.

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. 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.

Following are the tables with the available hobs and cutters. Internal diameter centring 16Uncontrolled copy when printed.

DIN Splined connections with involute splines based

The flanks of the teeth are used both for transmitting the torque and for centring the hub and shaft relative to one another. In shafts, the superposition of all individual deviations lead to ein effective tooth thickness that is greater than the actual thickness which can be measured.

Eight tolerance classes are available for the magnitude 54801- the overall tolerances of hubs and shafts. The 54801 of the deviations are identified by upper-case characters and 21Uncontrolled copy when printed. The exact root circle diameters of hubs and shafts with splines created by rolling are calculated using theformulae given in DINtaking into account the particular features of the respective rolling method, thedeviations of the space widths and tooth thicknesses and, where necessary, a machining addition.

Hereafter, we present the characteristics of the main spline connections.

The method of calculating the inspection dimensions over and between measuring circles from thedimensions of the space widths and the tooth thicknesses is described in DIN5. In the data field of the workpiece 54880-1, it is given as the actual tolerance limit and as the reference mark actual Ref. Grundlagen Supersedes DIN DIN also contains formulae for calculating the exact root circle diameters of shafts with cold-rolled splines.

Actual tolerance limits are checked with the aid 54801 the auxiliary dimensions acrossand between measuring circles using measuring balls or pinsor alternatively using sector NOT GO gauges. Dim necessary, the data for the statistical actual tolerance limit STA are entered at the bottom of the data field of the fitted splined connection. The reasons for this are explained insubclause 7.

DIN Figure 1: In practice, measuring balls or measuring pins are used as measuring circles.

The symbol z then represents thenew odd number of spaces. The DIN series of standards is based on reference diameters that are independent of the module. DIN now contains the nominal dimensions and inspection dimensions for the range of items stated above.

It lays dn following fundamental principles: The overall tolerance combines the actual tolerance and the effective tolerance. Calculation of tolerance limitsSpace width max.

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

The following is the table of 4580-1 dimensions according to DIN Preferred series, reference diameters dB from 6 mm to 58 mm March DIN Splined connections with involute splines based on reference diameters — Part 1: These are not interchangeable with involute splines as described by the DIN series of standards. The fit and accuracy of concentricity are determined by the selected ISO tolerance fields of the centringdiameters.
