Straight cylindrical involute splines
(Metric series of teeth with the side)
Part 2. 30 ° pressure angle dimension table
1 Scope
This part of GB/T 3478 specifies a 30 ° standard pressure angle flat tooth root and round tooth root (hereinafter referred to as 30 ° flat tooth root and 30 ° round root)
All the splines required for involute splines of cylindrical straight teeth.
This part applies to GB/T 3478.1-2008 standard in the provisions of the pressure angle of 30 °, the modulus of 0.5mm ~ 10mm,
The involute spline.
The size of this part of the table is according to GB/T 3478.1-2008 Table 3 formula and the tooth side with H/h, and the use of basic test methods
Compiled.

3 size table
3.1 30 ° flat tooth root and 30 ° round tooth root, the modulus of 0.5mm ~ 10mm, the tolerance level of 4,5,6 and 7 of the spline size table, see Table 1 ~
Table 28.
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 8 ~ Table 21.
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.
