Technical field
The present invention relates to a kind of gear-box, the planetary gear transmission mechanism of especially relevant wind power generation gear case.
Background technique
Wind power generation gear case Operation Conditions is complicated, and driving torque is large, and in gear-box, each gear mesh lubricating requirement is very high.Reasonably lubricating system can improve the mechanical efficiency of transmission system, more can significantly improve the working life of each gear.Existing wind power generation gear case generally adopts pressure lubrication, carries out forced feed lubricate by oil pipe fixing on casing to the planet carrier bearing of running and the planetary bearing in planet carrier etc.Because oil circuit is distributed in the planet carrier of static casing and running, therefore generally will on baroque planet carrier, process oil duct, difficulty of processing is larger, and existing planet wheel bearing forced lubrication device also exists the bad adjusting of fuel delivery, need sealing part, the deficiencies such as inconvenience assembling.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, be convenient to manufacturing, and fuel delivery can be according to the planet wheel bearing forced lubrication device of regulating working conditions.
The technological scheme that realizes above-mentioned purpose is: a kind of planet wheel bearing forced lubrication device, comprise casing, planet carrier, planetary pinion, bearing and planet pin, planet carrier is rotatably supported on casing, planet pin is contained on planet carrier, planetary pinion is rotatably supported on planet carrier by bearing, on the inner side surface relative with inner side surface casing described planet carrier, there is the protruding gear of ring-type, between the inwall of the inner side surface of described planet carrier and the protruding gear of ring-type, form centrifugal collection chamber, on described casing, there is oiling road and be provided with nozzle, oiling road communicates with nozzle, the centrifugal collection chamber of the outlet of nozzle on planet carrier, on described planet pin, there is oily passage, the import of oil passage communicates with centrifugal collection chamber, the bearing place that is positioned at planet pin outside is led in the outlet of oil passage.
The protruding gear of described ring-type is the ring being fixedly mounted on the inner side surface of planet carrier.
The protruding gear of described ring-type is the collar flange with planet carrier one.
The protruding gear of described ring-type has towards the reducing of the inner side surface direction of casing.
Oily passage on described planet pin is the axial blind hole of the open the other end sealing in one end, and the outlet of oily passage is positioned on the circumferential surface of planet pin and has a plurality of.
On the circumferential surface of described planet pin, also cover has lining, and two bearings are housed on lining, on lining, have with planet pin on the oilhole that connects of oily channel outlet, oilhole leads to the neutral gear place between two bearings.
Adopt after the structure of technique scheme, owing to thering is the protruding gear of ring-type on the inner side surface relative with inner side surface casing planet carrier, between the inwall of the inner side surface of planet carrier and the protruding gear of ring-type, form centrifugal collection chamber, on casing, there is oiling road and be provided with nozzle, oiling road communicates with nozzle, and the centrifugal collection chamber of the outlet of nozzle on planet carrier, has oily passage on planet pin, the import of oil passage communicates with centrifugal collection chamber, and the bearing place that is positioned at planet pin outside is led in the outlet of oily passage.Therefore utilize planet carrier rotation to produce centrifugal force, oil effectively can be delivered to the bearing place on planet carrier, without any need for sealing, along with the rising of rotating speed, it is large that centrifugal force becomes, cold oil transfer efficiency uprises, due to rise of rotational speed, bearing heating amount increases, and also needs more cold oil simultaneously, fuel delivery can be according to regulating working conditions, and adaptability for working condition is good; Amount of parts is less, need on planet carrier, not process oil duct, rational in infrastructure, greatly reduce difficulty of processing, is convenient to manufacture; In addition, nozzle is located on casing, is convenient to install, dismantle.
Accompanying drawing explanation
Fig. 1 is the structural representation of planet wheel bearing forced lubrication device of the present invention;
Fig. 2 is the structure enlarged diagram of the protruding gear of ring-type in the present invention.
Embodiment
The present invention is further detailed explanation for the embodiment who provides below in conjunction with accompanying drawing.
As Fig. 1, shown in 2, a kind of planet wheel bearing forced lubrication device, comprise casing 1, planet carrier 4, planetary pinion 5, bearing 6 and planet pin 8, planet carrier 4 is rotatably supported on casing 1, planet pin 8 is contained on planet carrier 4, planetary pinion 5 is rotatably supported on planet carrier 4 by bearing 6, on the inner side surface 4-1 relative with inner side surface 1-2 casing 1 described planet carrier 4, there is the protruding gear 3 of ring-type, between the inwall of the inner side surface 4-1 of described planet carrier 4 and the protruding gear 3 of ring-type, form centrifugal collection chamber 9, on described casing 1, there is oiling road 1-1 and be provided with nozzle 2, oiling road 1-1 communicates with nozzle 2, the centrifugal collection chamber 9 of the outlet of nozzle 2 on planet carrier 4, on described planet pin 8, there is oily passage 8-1, the import 8-1-1 of oil passage 8-1 communicates with centrifugal collection chamber 9, the outlet 8-1-2 of oil passage 8-1 leads to bearing 6 places that are positioned at planet pin 8 outsides.
As shown in Figure 1, 2, for the ease of the protruding gear 3 of ring-type is set, the protruding gear 3 of described ring-type is the rings that are fixedly mounted on the inner side surface 4-1 of planet carrier 4.Certainly, the protruding gear 3 of described ring-type can be also the collar flange with planet carrier 4 one.
As shown in Figure 1, 2, for the ease of collecting the oil from nozzle 2, the protruding gear 3 of described ring-type has towards the reducing of the inner side surface 1-2 direction of casing 1.
