3 size table

3.1 45 ° round tooth root, the modulus of 0.25mm ~ 2.5mm, the tolerance level of 4,5,6 and 7 of the spline size table, see Table 1 ~ Table 18. 3.2 The limit deviation of the inner spline diameter Di and the tolerance of the outer spline diameter Dee See GB/T 3478.1-2008. 3.3 Internal spline diameter Dei and outer spline diameter Die tolerance, from GB/T 1800.1 standard tolerances IT12, IT13 or IT14 Select. 3.4 When the inner and outer splines are machined, the radius of the tooth root is changed. This part gives the minimum radius of curvature of the tooth root arc. GB/T 3478.1-2008 Table 26. 3.5 When the selected test method is not the basic method, its role in the maximum cogging width, the actual maximum tooth width, the minimum tooth thickness and The actual maximum tooth thickness is calculated as follows. The maximum tooth width of the role of Evmax = Emax-λ; The actual tooth width is the minimum value Emin = Evmin + λ; The minimum tooth thickness Svmin = Smin + λ; The actual maximum tooth thickness Smax = Svmax - λ. 3.6 When the spline tooth side with the category is not H/h, the size of the size of the spline in the size table should be calculated according to the following formula. The maximum tooth thickness Svmax = S + esv; Actual tooth thickness minimum value Smin = Svmax- (T + λ). Where. Esv --- on the role of tooth thickness on the deviation, see GB/T 3478.1-2008 Table 23; (T + λ) --- total tolerance, see GB/T 3478.1-2008 Table 7 to Table 15. See page 24 for details on the large diameter of the large splines and trails. 3.7 Size table Chinese and foreign splines involute start circle diameter maximum value DFemax value is based on the principle of the principle of tooth-type tool derivation of the formula Calculated. When the spline tooth side with the category is not H/h, DFemax can be calculated according to the formula in Table 3 of GB/T 3478.1-2008.
