For undated references, the latest edition of the referenced document including any amendments applies.
We have no document history for this standard. Your Alert Profile lists the documents that will be monitored. It istherefore recommended that these be indicated in the form of a data field, see figure 6. These are not interchangeable with involute splines conforming to the DIN series of standards.
Refer to Table 5 for recommended tolerance fields and deviations for the root and tip diameters. 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 DIN series of standards is based on reference diameters that are independent of the module, allowing an optimal fit to standard ball and roller bearing diameters and reducing the number of different tools required for manufacturing. DIN covers quality inspections of fitted splined connections.
If either the reference diameter or the module lie outside of the defined range, the adjacent edge value in the table is used as cFmin. The definitive fit parameter is that for the flanks, the backlash. In the data field of the workpiece drawing, it is given as the actual tolerance limit and as the reference mark actual Ref. The statistical actual tolerance limit permits a certain number of measurements to exceed the tolerance limits by a specific value.
The symbol z then represents thenew odd number of spaces. This avoids excessive reject rates, which would not occur if fewer measurements were to be taken.
The flanks of the teeth are subject to individual deviations from the profile, the flank line and the pitch. The difference between the space width and the tooth thicknessdetermines the rotational backlash.
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. The standard has been editorially revised.
Calculating spline connections according to DIN with diameter centering
Involute splines in accordance with ISO are based on module series. The method of calculating the inspection dimensions over and between measuring circles from thedimensions of the space widths and dn tooth thicknesses is described in DIN5.
Already Subscribed to this document. When the root circle tolerances are calculated according to the basic standard DIN table 5the root form diameter is calculated as specified by the formulae on page These should therefore only be 5480-6 in a few exceptional cases. The entire series of standards now consists of only four parts instead of the previous sixteen.
