Profiled contour for gearwheel teeth has base profile pitch function fulfilling certain conditions whereby start value on root profile start is smaller than end value on tip profile end

摘要

The profiled contour for the teeth of gearwheels has an active contour progression from a starting value (24) on the root profile start to an end value (26) on the tip profile end for an associated rotational angle parameter range (psi ) with a basic profile pitch function (22). The base profile pitch function for the aforesaid range fulfills certain conditions whereby the start value (alpha AP) is smaller than the end value (alpha EP), and the pitch of the base profile pitch function is constantly smaller in the overall range (psi ).
