39、asuring methods Symbols for gear teeth standards and their errors Explanations When the ”Gear tooth tolerances” Sub-committee started revising the DIN Standards on tolerances for cylindrical gear teeth it was faced with the question whether the tolerances contained in IS0 1328 - 1975 could be taken
40、over complete. After a thorough examination the com- mittee 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
41、with regard to a few points was a general redifining 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 shownin practice that for the same module
42、 the profile deviations do not become larger with increasing diameter (increasing number of teeth). The profile tolerances therefore remain only moduledependent and no longer diameterdependent. A general review of the alterations undertaken is given in the Explanations in DIN 3961. The terms, design
43、ations 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 DI
44、N 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 calculated from the tolerance equations had for the most part been rounded upwards, whereas in the new
45、 Standard they have been rounded up or down to the nearest preferred number. The diameter range has been enlarged in the upward direction to module rn = 70 mm and diameter d = 10 O00 mm. Regardless of whether all deviations are measurable, the numerical values in the Tables of DIN 3962 Part 1 and DI
46、N 3963 have been listed com pletely in the interests of future applications. The module range rn 1 has been deleted, see in this connection DIN 58 405. The arrangement of the toler- ance Standards has been altered so that the tooth trace deviations have been grouped with the individual devi- ations
47、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 devi- ation and pitch-span deviation and the large amount of spread in their rela
48、tionship to the pther tolerances, which were features objected to in IS0 1328 - 1975, are defined more in keeping with practical requirements in DIN 3962 and DIN 3963.
