Description
Technical field
The present invention relates to a kind of wind power gear case high speed axis to keep off oily trapped fuel composite structure, belongs to box bearing lubrication
Technical field.
Background technique
It rubs tower height tower direction since wind-powered electricity generation is past at present to develop, high to gear-box lightweight requirements, weight is light, and size is wanted
Small, gear-box inner space is smaller and smaller, and high gear is more and more closer with the bearing distance of safety thereon, such gear engagement
Hot oil is easy to influence the temperature of bearing.
Additionally, due to many unit allocations are immature or even the entire Wind turbines of one-key start, cause when opening, gear
Case lubricating oil also has little time to reach oil site, is easy to cause serious influence to bearing, serious even burn bearing, and wind turbine
Group transmission chain is disposed with certain inclination angle, and speed end considers trapped fuel simultaneously it is also contemplated that sealing is asked in the back lower place, in bearing rear end
Inscribe it is relatively difficult, therefore in order to guarantee bearing lubrication, it is necessary to which considering can be always with the presence of oil guarantee bearing lubrication at bearing.
Summary of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and a kind of simple and compact for structure, the part provided
Few at low cost, manufacture, installation accuracy wind power gear case high speed axis of less demanding keep off oily trapped fuel composite structure.
The purpose of the present invention is what is completed by following technical solution, a kind of wind power gear case high speed axis gear oil is deposited
Oily composite structure, specifically include that high speed shaft, oil scraper ring, bearing block, combination bearing, bearing spacer, oil return hole, baffle, washer,
Bolt, trapped fuel chamber, the oil scraper ring and combination bearing are commonly mounted on high speed shaft by the cooperation of front-rear position；Described
Bearing spacer is mounted between combination bearing outer ring, the bearing block by being coupled in bearing outer ring, the bearing every
Circle is provided with bearing forced feed lubrication oil and passes through and enter the lubrication bearing aperture between combination bearing.
As preferred: the cross sectional shape of oil baffle is the boot-shaped laid flat, is kept off between high speed shaft gear and combination bearing,
Sole is contacted with high speed shaft step, another side and bearing touch.
As preferred: the oil return hole is opened in bearing block lower end and is tilted a certain angle and gear box cavity with horizontal axis
Logical, the baffle is mounted on bearing block by bolt and washer, and baffle cross sectional shape is chair shape, and the back side is spherical crown section
Shape, and so that baffle, oil scraper ring and bearing is formed one in combination bearing front end and can store certain lubricating oil, in gear-box starting
When the trapped fuel chamber of lubricating action is played to bearing.
For the present invention using oil baffle is installed before combination bearing, the hot oil for blocking high gear engagement influences bearing, avoids
Bearing heating problem.
The present invention forms trapped fuel chamber by oil baffle, bearing and baffle, can prevent forced feed lubrication oil from not reaching in this way
Oil site, when gear-box is run, bearing does not have lubricating oil and bring endangers.
The present invention has simple and compact for structure, and part is few at low cost, manufacture, the features such as installation accuracy is of less demanding.
Detailed description of the invention
Fig. 1 is that wind power gear case high speed axis of the invention keeps off oily trapped fuel combining structure schematic diagram.
Fig. 2 is the schematic diagram after baffle installation of the present invention.
Specific embodiment
The present invention will be described in detail below with reference to the accompanying drawings: Fig. 1, shown in 2, a kind of wind turbine gearbox of the present invention
High speed axle bumper oil trapped fuel composite structure, specifically include that high speed shaft 1, oil scraper ring 2, bearing block 3, combination bearing 4, bearing spacer 5,
Oil return hole 6, baffle 7, washer 8, bolt 9, trapped fuel chamber 10, the oil scraper ring 2 and combination bearing 4 by the cooperation of front-rear position,
It is commonly mounted on high speed shaft 1；The bearing spacer 5 is mounted between 4 outer ring of combination bearing, and the bearing block 3 is by matching
Conjunction is installed on bearing outer ring, and the bearing spacer 5 is provided with bearing forced feed lubrication oil and passes through and enter between combination bearing
Lubricate bearing aperture.
The cross sectional shape of the oil baffle is the boot-shaped laid flat, keeps off the sole between high speed shaft gear and combination bearing
It is contacted with high speed shaft step, another side and bearing touch.
As shown in the figure, the oil return hole 6 be opened in 3 lower end of bearing block and with horizontal axis be tilted a certain angle in gear-box
Chamber is logical, and the baffle 7 is mounted on bearing block 3 by bolt 9 and washer 8, and makes baffle 7, oil scraper ring 2 and bearing in built-up shaft
Brought forward end forms one and can store certain lubricating oil, plays the trapped fuel chamber 10 of lubricating action to bearing in gear-box starting,
The baffle cross sectional shape is chair shape, and the back side is spherical crown section shape.
The principle of the present invention is: oil baffle is installed between gear and bearing, the hot oil for preventing gear from engaging influences bearing,
It in this way can be to avoid bearing temperature height；A trapped fuel chamber is formed in bearing front end between oil baffle, bearing and baffle, storage is certain
Lubricating oil and control baffle size to provide lubrication when gear-box starting for bearing, guarantee to form trapped fuel chamber, and not
The unobstructed of oil return can be blocked.
