A gear box of a wind power plant rotor, namely a planetary gear box, which is intended for transmission of relatively high power at relatively low rotational velocity, comprises during operation stationary gear rim (2) with inner teeth jointed with a shaft (200), at least three with a slowly rotating and for high power transmission arranged driving shaft (300) jointed planetary gears (3, 3', 3"), which are engaged with the above mentioned gear rim (2) as well as among the planetary gears (3, 3', 3") centrally arranged sun gear (1), which is arranged to mesh with each of them and jointed with a driven shaft (100). In order to avoid micro pitting, each of the gears (1, 2, 3, 3', 3") is equipped with characteristic toothing, where the basic tooth (6) flank profile is defined by a rack (5) flank profile in accordance with equations (I) and (II). |
