Waste lubricating grease collecting structure of wind driven generator spindle bearing

Abstract

The invention discloses a waste lubricating grease collecting structure of a wind driven generator spindle bearing. The waste lubricating grease collecting structure of the wind driven generator spindle bearing has the advantages that a first grease collecting bottle is fixed to a turntable through a first grease delivery pipe and is communicated with a roller moving cavity through the first grease delivery pipe and a first grease outlet in the turntable, and a second grease collecting bottle is fixed to a rotor through a second grease delivery pipe and communicated with the roller moving cavity through the second grease delivery pipe and a second grease outlet in the rotor. A grease collecting pipeline is shortened, air in the grease collecting bottles is easily exhausted and can produce certain suction force under the effect of centrifugal force due to the fact that the first grease collecting bottle and the second grease collecting bottle are installed on the turntable and the rotor respectively, waste lubricating grease can timely flow into the grease collecting bottles, and accordingly when a grease supply device supplies new lubricating grease, the new lubricating grease can well extrude the waste lubricating grease, and the waste lubricating grease can be fully replaced by the new lubricating grease.

Description

technical field [0001] The invention relates to a recovery device for waste lubricating grease, in particular to a collection structure for waste lubricating grease of a main shaft bearing of a wind power generator. Background technique [0002] In the early 1970s, due to the "oil crisis", there was a problem of energy shortage. People realized the instability and limitation of conventional mineral energy supply, so the search for clean and renewable energy has become an important issue in the modern world. Wind energy as Renewable, pollution-free natural energy has attracted people's attention. [0003] A wind turbine is a power machine that converts wind energy into mechanical work. Existing wind power generators mainly include a generator, wind blades and a main shaft. The rotating disk of the wind blades and the rotor of the generator are fixed to the main shaft through bearings. The first sealing structure of the turntable and the inner ring of the bearing on one sid...

AI Technical Summary

Problems solved by technology

Among them, the waste oil recovery device is generally an oil collection bottle fixed on the main shaft, but since the oil collection bottle is in a static state and the recovery oil path between the oil collection bottle and the movable cavity of the bearing roller will be relatively long, so in the automatic supply When the oil device supplies new lubricating grease to the movable cavity of the bearing roller, the waste lubricating grease in the movable cavity of the bearing roller has not been recovered in time, resulting in insufficient replacement of new lubricating grease and waste lubricating grease. The accumulation of waste lubricating grease will cause excessive oil pressure to form an impact on the skeleton sealing ring, resulting in failure of the oil seal, causing waste lubricating grease to overflow from the sealing structure, causing pollution to the wind turbine, and in serious cases, the overflowing waste lubricating grease will be ignited resulting in fires and significant economic losses
