Where necessary, the data for the statistical actual tolerance limit STA are entered at the bottom of the data field of the fitted splined connection. Subtract and add these values to your nominal value to calculate min and mas value. They determine the design value of the connection diameter.

WN2 – Toothed Shaft Design

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.

The tolerance classes define themanufacturing tolerances. 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. For limits of centring accuracy, see DIN The permissible surface pressures are determined from material properties, so it is possible to use special materials. 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 Table 1: View in Fullscreen Report. The difference between the space width and the tooth thicknessdetermines the rotational backlash.

Close this window and log in. The geometry can be selected conveniently from a data base.

Refer to table 5 for recommended tolerance fields and deviations of the root circle and tipcircle diameters. Refer to table 5 for recommended tolerance fields of the root circle and tip circle diameters. This series of standards has been revised by Technical Committee invooute.

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.

Yes thank you, I know how to calculate the pin size and the measure between them. DIN for all calculations in respect of fitted splined connections. In shafts, the superposition of all individual deviations lead to an effective tooth thickness that is greater than the actual thickness which can be measured.

By joining you are opting in to receive e-mail. In DINI can find the nominal value in the tables, when you are measuring between 2 pins, but i invopute seem to find the formula to calculate to calculate the min and the max values I have seen some earlier posts, where “gearguru” answered a similar question, but he only showed the values, not the calculations Any help would be appreciated.

The statistical actual tolerance limit permits a certain number of measurements to exceed the tolerance limits by a specific value. Imprint Print to Top.

Materials can be selected from the data base. For space widths of hubs and tooth thicknesses of shafts, this standardprovides deviation series and tolerances based on the nominal dimensions, see figure 7.

DIN now contains the nominal dimensions and inspection dimensions for the range of items stated above. All the equations and charts are there for you to calculate the required tolerances. This means that the respective workpiecesmay not be rejected because of individual deviations.

March DIN Splined connections with involute splines based on reference diameters — Part 1: The Eng-Tips staff will check this out and take appropriate action. I just don’t know how to specify the correct tolerance. This standard can also be applied, however, to design diameter-centred connections. As analternative, this can also be done using the deviation factors as described in DIN For details, see DIN5.

DIN For further information, we refer to the relevant standard. A certain amount of experience is needed in selecting the deviations and tolerances suitable for practical applications.
