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
The present invention relates to a kind of retracting device of waste lubricating oil fat, especially relate to a kind of mainshaft bearing of wind-driven generator and give up
The collection structure of lubricant grease.
Background technology
At the initial stage seventies, due to " oil crisis ", occur in that energy-intensive problem, people recognize conventional fossil energy
The unstability of supply and finiteness, the regenerative resource then seeking to clean becomes an important topic of Modern World then,
Wind energy causes people as reproducible, free of contamination natural energy resources and payes attention to.
Wind-driven generator is exactly a kind of dynamic power machine that wind energy is converted to mechanical work.Existing wind-driven generator mainly wraps
Include generator, fan blade and main shaft, the rotating disk of fan blade and the rotor of generator are fixed with main shaft by bearing, for ensureing the suitable of bearing
Smooth work, need bearing roller activity cavity oil sealing, generally comprise that to be located at bearing side rotating disk close with the first of bearing inner ring
Seal structure and the second seals structure being located at the rotor of bearing opposite side and bearing inner ring or main shaft, sealing structure is mainly by skeleton
Sealing ring forms；It is additionally provided with the automatic oil supplying device for supplying new oil fat and for collecting the useless of waste lubricating oil fat simultaneously
Oil recovery apparatus, automatic oil supplying device and drain oil recovery equipment are incorporated on main shaft, and the supply oil circuit of automatic oil supplying device passes through
Fuel feed hole on bearing inner ring is connected with bearing roller activity cavity, and bearing roller activity cavity is passed through fuel-displaced on bearing inner ring
Hole is connected with the recovery oil circuit of drain oil recovery equipment, and automatic oil supplying device supplements new oil according to intervals to bearing
Fat, waste lubricating oil fat then enters back drain oil recovery equipment by recovery oil circuit.Wherein, drain oil recovery equipment is generally fixed on master
Oil-collecting bottle on axle, but because oil-collecting bottle remains static and the oil recovery between oil-collecting bottle and bearing roller activity cavity
Road can be long, and therefore in automatic oil supplying device when supplementing new oil fat to bearing roller activity cavity, bearing roller is lived
Waste lubricating oil fat in dynamic cavity does not also reclaim in time, leads to new oil fat and the replacement of waste lubricating oil fat also not to be filled
Point, new oil fat and the collection party of waste lubricating oil fat simultaneously leads to excessive backbone sealing ring is formed of oil pressure to be impacted, and leads to oil
Envelope lost efficacy so that waste lubricating oil fat overflows at sealing structure, wind-driven generator was polluted, the useless lubrication overflowed when serious
Grease can be ignited thus initiation fire, causes heavy economic losses.
Content of the invention
The technical problem to be solved is that a kind of oil recovery of offer is short out, and new oil fat is filled with waste lubricating oil fat
Point replace, the collection structure of mainshaft bearing of wind-driven generator waste lubricating oil fat that waste lubricating oil fat can reclaim in time.
The present invention solves the technical scheme that adopted of above-mentioned technical problem：A kind of mainshaft bearing of wind-driven generator gives up and lubricates
The collection structure of grease, including the first sealing structure between the rotating disk being arranged on bearing side and bearing inner ring, is arranged on axle
Hold the second seals structure between the rotor of opposite side and bearing inner ring and be arranged on bearing inner ring and connect fueller and rolling
The fuel feed hole of subactivity cavity, described first sealing structure and second seals structure coordinate for by the roller activity cavity of bearing
Oil sealing；Also include the first receipts oil assembly and second and receive oily assembly；Described first receipts oil assembly includes the first oil-collecting bottle and first and leads to
