Abstract
The utility model discloses a kind of semi-direct driving wind electrical gearbox, the fuel feed pump including cabinet, setting surface outside the enclosure；The exit of fuel feed pump is provided with the spray bar one of insertion case intracorporal ring gear tooth root lower part side, and the opening of the spray bar one has the lengthening of spray distance, the diffusion effect of fluid is more preferable towards ring gear tooth root top and opening oil spout from bottom to top；Neighbouring more flank of tooth can be lubricated, sufficient lubrication are obtained when engaging gear, to guarantee the service life of gear.
Description
Technical field
The utility model relates to gear-boxes, are related to a kind of semi-direct driving wind electrical gearbox.
Background technique
Wind energy is one of the most abundant renewable energy in the world.Blower rotates under the promotion of wind energy, continuously
Export electric energy.This reproducible using energy source mode has all obtained rapidly developing in the whole world in the past few years.Drive generator
The wind turbine gearbox of operating can be described as the heart of gear drive type blower, due to the normal operation to whole system to Guan Chong
It wants.For wind turbine gearbox, lubricating system is most important, and wind turbine gearbox is able to maintain wind power gear under lubricant environment
Case works normally, and when due to wind turbine gearbox work, generates very big torque, once therefore gear-box lack lubricating oil, gear
Between cog interaction force in case is very big, causes gear piece broken, gear-box is caused to damage.
Oil supply system is arranged using external in existing gear-box, and nozzle is inserted into the endface of the tooth of gear-box, in practical survey
It is found during examination, normal nozzles use top-down injection mode, and the oil that nozzle sprays can only directly act on tooth on a small quantity
Between lubricate, between cog obtain lubricating oil be less than standard lubricating oil quantity, will cause gear-box premature failure in this way.
Utility model content
Purpose of utility model: the purpose of the utility model is to provide a kind of semi-direct driving wind electrical gearboxes, have spray distance
Lengthening, the diffusion effect of fluid is more preferable；Neighbouring more flank of tooth can be lubricated, sufficient profit is obtained when engaging gear
It is sliding, to guarantee the service life of gear.
Technical solution: semi-direct driving wind electrical gearbox described in the utility model, including cabinet, setting surface outside the enclosure
Fuel feed pump；The exit of fuel feed pump is provided with the spray bar one of insertion case intracorporal ring gear tooth root lower part side, the spray bar
One opening towards ring gear tooth root top and opening oil spout from bottom to top,
Spray bar one is arranged in pairs, and ring gear tooth root two sides are arranged in cabinet in spray bar one.
The spray bar two of the preposition bearing for lubrication motor axis is provided on fuel feed pump, cabinet is arranged in spray bar two
Bearing roller oil spout on flange sidewalls and towards preposition bearing.
By using above-mentioned technical proposal, in fuel feed pump fuel feeding to spray bar one, spray bar one is embedded in the ring gear of cabinet
At tooth root lower part, since the opening of the spray bar one is towards ring gear tooth root top, so the oil that spray bar one sprays is oblique
On ring gear tooth root top and the flank of tooth, so that gear obtains sufficient lubrication when engaging；In order to keep gear to lubricate adequately
It works under environment, spray bar one is arranged in pairs, and opening direction is all directed towards ring gear tooth root top.Spray bar two is to generator
The preposition bearing oil spout of axis.
The utility model has the advantages that the lengthening of spray distance, the diffusion effect of fluid is more preferable, can lubricate neighbouring more flank of tooth,
Sufficient lubrication is obtained when engaging gear, to guarantee the service life of gear；The preposition bearing of generator shaft does pressure profit
It is sliding, guarantee that bearing obtains sufficient lubrication and heat dissipation, improves the service life of bearing.

Fig. 2 is the partial structure diagram of semi-direct driving wind electrical gearbox and motor junction；
Fig. 3 is the partial structure diagram under semi-direct driving wind electrical gearbox left view.
Specific embodiment
As shown in Figure 1, a kind of semi-direct driving wind electrical gearbox, including cabinet 1, the fuel feed pump 2 of 1 outer surface of cabinet is set；
The exit of its fuel feed pump 2 is provided with the spray bar 1 of the ring gear tooth root lower part side in insertion cabinet 1, the spray bar 1
Opening towards ring gear tooth root top and opening oil spout from bottom to top, spray bar 1 is arranged in pairs, and the setting of spray bar 1 exists
Ring gear tooth root two sides in cabinet 1.
In fuel feed pump 2 fuel feeding to spray bar 1, spray bar 1 is embedded at the ring gear tooth root lower part of cabinet 1, due to this
The opening of spray bar 1 towards ring gear tooth root top, so the oil that spray bar 1 sprays be oblique ring gear tooth root top and
On the flank of tooth, so that gear obtains sufficient lubrication when engaging；Spray bar 1 is arranged in pairs, and opening direction is all directed towards internal tooth
Tooth root top is enclosed, in order to keep gear both ends all to work under sufficient lubricant environment.
As shown in Figures 2 and 3, in order to solve generator because of under high speed conditions, preposition bearing heating is serious to be asked
Topic, is provided with the spray bar 24 of the preposition bearing for lubrication motor axis on fuel feed pump 2, and spray bar 24 is arranged in cabinet 1
Flange sidewalls on and towards the bearing roller oil spout of preposition bearing.In order to enable oil liquid can be recycled, 1 bottom of cabinet
The oil return opening 5 of lubricating oil for recycling the ejection of spray bar 24 is set, and the lubricating oil after bearing passes through under rear box 1
The oil return opening 5 of side flows back to inside gear-box again, and into the fuel feed pump 2 of lubricating system, then lubricating system is continual right
Bearing is lubricated.
Spray bar 24 is under relatively steady state and works in order to prevent, is provided on 1 flange of cabinet for fixed spray
The fixinig plate 6 of oil pipe 24.
