Abstract

The invention relates to a storage device (2) for storing energy in the form of potential energy, comprising at least one potential energy store (4) for receiving, storing, and dispensing energy, at least one guide means (6) for guiding the potential energy store (4) along a guide path (8), wherein the guide path (8) is arranged within a shaft (10) arranged in the ground vertically relative to the Earth's surface, and the potential energy store (4) obtains the stored potential energy by converting kinetic energy into potential energy and dispenses the potential energy by converting same into kinetic energy. The kinetic energy results from a movement of the potential energy store (4) along the guide path (8), and the potential energy store (4) is constructed in the form of a continuous weight which extends over the length of the guide path (8).

Abstract

The invention relates to a planetary gearing mechanism for a wind turbine, comprising at least one planetary stage (1, 2) that has a planet carrier (3, 4) on which a plurality of planetary gears (5, 6) are arranged, each planetary gear (5, 6) being mounted by a planetary gear bearing (7, 8) and meshing with both a sun gear (11, 12) and a ring gear (9, 10) that is rigidly connected to a gearing housing (30), said gearing mechanism also comprising means for supplying a lubricant to the planetary gear bearings (7, 8), a central distributor (20) being provided, as said means, which extends inside the gearing housing (30) and which is in the form of a closed annular channel (21) with at least one inlet point (22) and one outlet point (23a, b). The lubricant can be introduced into the annular channel (21) via the inlet point (22), and conveyed out of the annular channel (21) to the planetary gear bearings (7, 8) via the outlet point (23a, b).
