Geometry-Fine Sizing for 4 gears

Center distances cannot be changed in the fine sizing process. The center distances entered in the Basic data tab are used in this calculation.

However, if gear 4 is an internal toothing, you can also select the "double planetary stage" option. If you select the "double planetary stage" option, the internal gear's V-circle and the required output reduction z3/z2 are checked. In this case, all center distances are varied automatically, and all possible solutions are displayed. Values for αM213, clearance13 and clearance24 are displayed in the results.
