Abstract
A planetary transmission with a planetary gearset (RS1), having a satellite carrier with planetary gearwheels (11, 14), mounted bolts (12, 15) attached to the satellite carrier. The satellite carrier comprises a web plate (17) via which lubricant is fed to the planetary gearwheels (11, 14) through lubricant bores in the bolts (12, 15) of the planetary gearwheels (11, 14). A structural element adjacent to the web plate (17) has no rotation speed relative to the web plate (17). A static-seal element (18) is arranged between the web plate (17) and the structural element adjacent to the web plate (17) above the bolts (12, 15) so that a lubricant chamber (109) is formed between the web plate (17) and the structural element adjacent to the web plate (17). Lubricant flows into this chamber (109), accumulates therein, and passes from the chamber (109) into the lubricant bores of the bolts (12, 15) of the planetary gearwheels (11, 14).
