Grading design and calculation of gear spindle
Grinding high-precision step wheels requires two inner rails with perfect precision. This spindle should ensure the matching distance of a workpiece hole control. After adding 1 to the same part, the hole diameters are different within the allowable tolerance range. It is recommended to have a side gear spindle to match it to meet the requirement of small spacing. This is in line with the reasonable grading design of the spindle. The following is a set of formulas as a reference for the design of the inner shaft of the graded grinding mill:
) Basic size of the graded core
d s-Po+(t - 1) ×
6) Limit deviation of the graded core
Where: Base size of the lower hole, mm;
41 Filling difference, mm;
1 Mandrel grade number;
· Mandrel grade serial number.
Example: The gear hole grid 3I17 (\.021) milling core is required to be graded. Requirement: Substituting into formula A, we get formula A2:
d1-30+(1 - 1)×
d g0=30+(2 - 1)×
d a20+(3
d sn=30-(4 - 1) x
