For choosing the number of keys depending on the diameters and of the load, as also for indicating the tolerances according to the desired fit loose, sliding, straining we refer to the tables published by the various standardization organizations: This series of standards has been revised by Technical Committee 2. For choosing the number of keys depending on the diameters and of the load, as also for indicating the tolerances according to the desired fit loose, sliding, straining we refer to the tables published by the various standardization organizations:.

Even numbers of teeth have been given preference in tables 1 and 2.

Diameter-centred connections necessitate greater manufacturing effort due to the small tolerances of thecentring diameters and the measures required to limit 5480–1 offsets between the centring diameter centre andthe centre of the tooth circle.

For datedreferences, only the edition referred to 54880-1 to this standard. DIN Data to be shown on drawings9. 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.

DIN For further information, we refer to the relevant standard.

Internal and external spline teeth

These have predefined relationships to one another. Uncontrolled copy when printed.

Figure1 shows an externally-centred shaft with splines. The following is the table of normalized dimensions according to DIN They determine the magnitude of the overall tolerance as well as the actual and effective individual tolerances. The calculation formulae, tolerances and deviations contained in Part 1 also apply to the other parts of this series of standards.

The manufacturing tolerance should be at least twice the expected tooth thickness variation Rs. Deviations and tolerances Reference diameters Modules Example: The deviation seriespermits the definition of free fits, transitions fits and interference fits. Principles Passverzahnungen mit Evolventenflanken und The selection of nominal dimensions is essentially determinedby the following condition: The tolerance classes define themanufacturing tolerances.

DIN Splined connections with involute splines based

These are not interchangeable with involute splines as described by the DIN series of standards. If a GO gauge does fit, this will in all caseseffectively ensure adherence to the tolerance limit.

If very many measurements are taken in different angular positions and measuring planes, it may be useful to apply statistical concepts when evaluating the actual tolerance limit. 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: Bierens at Tilburg NL.

DIN Validity This standard is valid from onwards. 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. Principles Passverzahnungen mit Evolventenflanken und Bezugsdurchmesser — Teil 1: Refer to table 5 for recommended tolerance fields of the root circle and tip circle diameters. It is notpossible to state standard values for this.

In the data field of the workpiece drawing, it is given as the actual tolerance limit and as the reference mark actual Ref. The symbol z then represents thenew odd number of spaces. The tolerances are depending on mounting conditions, shaft I z or tooth flank centering F z.

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.
