Abstract

The invention relates to a drive mechanism (1) for a wind power installation, which comprises at least one gear (2), which is supported on a shaft (5), wherein between the gear (2) and the shaft (5) there is arranged a gear (2) comprising: The bearing portion of the sliding bearing (4), and the shaft (5) is formed with a gap for supplying lubricant to the sliding bearing (4). In the region of the contact surfaces of the sliding bearings (4), grooves (18) are formed in the gears (2) or gaps (7) are formed between the sliding bearings (4), said grooves or recesses passing through at least the gears (2). A connecting channel (16) is connected to the ambient atmosphere, the connecting channel (16) being formed in the shaft (5).

Description

technical field [0001] The invention relates to a transmission for a wind power plant, comprising at least one gear, which is supported on a shaft, wherein a bearing point comprising a sliding bearing is arranged between the gear and the shaft, and in the shaft is formed a supply Lubricant to plain bearing clearance. Furthermore, the invention relates to a wind power plant gear comprising at least one gear, which is mounted on a shaft, wherein a bearing point comprising a plurality of sliding bearings is arranged between the gear and the shaft, the sliding bearings extending along the shaft. The directions are spaced apart from each other forming a gap, and a recess is formed in the shaft for supplying lubricant to the slide bearing. Background technique [0002] Gears are used in wind power installations to convert the relatively slow rotational movement of a wind rotor into a higher rotational speed in order thereby to operate a generator for generating electricity. Roll...
