1. A planetary gearbox, comprising a shaft having a channel structure for conducting a lubricant, comprising a channel opening on the outer face of the shaft, a planetary carrier, at least two planetary pins which are arranged on the planetary carrier and on which one planetary gear each is mounted, wherein each planetary pin has a channel structure for conducting the lubricant to a bearing of the planetary gear, and a lubricant-collecting tray which has a collection space, for collecting the lubricant supplied via the shaft-side channel, comprising at least two hollow feed ports which each open into a planetary pin-side channel structure for conducting the lubricant into the respective channel structure, wherein a feed port which is positioned, viewed in the circumferential direction, closer to the opening of the channel has a smaller opening cross-section (Q1) than a feed port which is positioned further away.
