DIN_3962-1-1978

1 Scope The tolerances listed in this Standard apply to the amounts of the deviations defined in DIN 3960. I t contains tolerances for: - profile form deviation ff - profile angle deviation f H ,

- total profile deviation F , - individual pitch deviation fp

- normal base pitch deviation f p e

- pitch error fu - total pitch deviation F , - pitch-span deviation over 1/8 of periphery Fp z/8

- concentricity deviation FI - tooth thickness fluctuation R, 1 )

2 Other relevant Standards DIN 3960 Definitions and parameters for cylindrical gears and cylindrical gear pairs with

involute teeth DIN 3961 Tolerancesfor cylindrical gear teeth; bases DIN 3962 Part 3 Tolerances for cylindrical gear teeth; tolerances for pitch-span deviations DIN 3967 System of gear f i t s ; backlash, tooth thickness allowances and tooth thickness toler-

ances; bases, calculation of tooth thickness allowances, conversion of allowances for the different measuring methods

Explanations When the "Gear tooth tolerances" Sub-committee start- ing revising the DIN Standards on tolerances for cylindrical gear teeth it was faced with the question whether the tolerances contained in I S 0 1328 - 1975 could be taken over complete. After a thorough examination the committee came to the conclusion that this would not be expedient for the purposes of German industry.

The DIN gear tooth tolerance system in use so far, the principles of which have not altered, has for the most part proved itself in practice. Only with regard to a few points was a general redefining of tolerances necessary. This applies particularly to the tolerances for single-flank working deviations, tooth trace deviations and, to some extent, for pitch-span deviations.

Apart from this, it has been shown in practice that for the same module the profile deviations do not become larger with increasing diameter (increasing number of teeth). The profile tolerances therefore remain only module-dependent and no longer diameter-dependent.

A general review of the alterations undertaken is given in the Explanations in DIN 3961.

The terms, designations and symbols have been redefined in accordance with DIN 3960, DIN 3998 and DIN 3999. Newly added parameters are the total profile deviation, pitch-span deviation, tooth trace form deviation and tooth trace total deviation.

The numerical specifying of tolerances derives from the equations in DIN 3961. Additional alterations of the tabulated numerical data result from the fact that the module and diameter ranges have been regraded and from the fact that the values in the old DIN Standards calcu- lated from the tolerance equations had for the most part been rounded upwards, whereas in the new Standards they have been rounded up or down to the nearest pre- ferred number. The diameter range has been enlarged in the upward direction to module m = 70 mm and diameter d = 10 O00 mm. Regardless of whether al l deviations are measurable, the numerical values in the Tables of DIN 3962 Part 1 and DIN 3963 have been listed com- pletely in the interests of future applications. The module range m < 1 mm has been deleted, see in this connection DIN 58405. The arrangement of the tolerance Standards has been altered so that the tooth trace deviations have been grouped with the individual deviations in DIN 3962 Part 2, whilst DIN 3963 contains only working deviations and DIN 3967 only the system of gear fits. In the opinion of German industry, the large tolerances for the two-flank working deviation, concentricity deviation and pitch-span deviation and the large amount of spread in their relationship to the other tolerances, which were features objected to in I S 0 1328 - 1975, are defined more in keeping with practical requirements in DIN 3962 and DIN 3963.
