Background technique
Wind power generation gear case running operating mode is complicated, and driving torque is big, and each gear mesh lubricating requirement is very high in the gear-box.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 through oil pipe fixing on the casing to the planet carrier bearing of running and the planetary bearing in the planet carrier etc. and lubricates.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 bigger, and also there is the bad adjusting of fuel delivery in existing planet wheel bearing forced lubrication device; Need sealing part, deficiencies such as inconvenience assembling.
Summary of the invention
The purpose of the utility model be 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, and the planet carrier rotational support is on casing; The planet pin is contained on the planet carrier; Planetary pinion on planet carrier, has ring-type protruding retaining on the inner side surface opposed inside face said planet carrier and casing through the bearing rotational support, forms centrifugal collection chamber between the inwall of the inner side surface of said planet carrier and the protruding retaining of ring-type; Have the oiling road on the said casing and be provided with nozzle; The oiling road communicates with nozzle, and the centrifugal collection chamber of the outlet of nozzle on planet carrier has oily passage on the said 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.
The protruding retaining of said ring-type is the ring that is fixedly mounted on the side of planet carrier.
The protruding retaining of said ring-type is the collar flange with the planet carrier one.
The protruding retaining of said ring-type has towards the reducing of the inner side surface direction of casing.
Oily passage on the said planet pin is the axial blind hole of the open the other end sealing of an end, and the outlet of oily passage is positioned on the circumferential surface of planet pin and has a plurality of.
Also be with lining on the circumferential surface of said planet pin, two bearings be housed on the lining, have on the lining with the planet pin on the oilhole that connects of oily channel outlet, oilhole leads to the neutral gear place between two bearings.
After adopting the structure of technique scheme,, form centrifugal collection chamber between the inwall of the inner side surface of planet carrier and the protruding retaining of ring-type owing to have the protruding retaining of ring-type on inner side surface opposed inside face planet carrier and casing; Have the oiling road on the casing and be provided with nozzle; The oiling road communicates with nozzle, and the centrifugal collection chamber of the outlet of nozzle on planet carrier has oily passage on the 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 the planet carrier rotation to produce centrifugal force, can oil effectively be delivered to the bearing place on the planet carrier, without any need for sealing; Along with the rising of rotating speed, it is big that centrifugal force becomes, and the cold oil transfer efficiency uprises; Because rotating speed rises, and the bearing heating amount increases, also need 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, and is rational in infrastructure, reduce difficulty of processing greatly, is convenient to make; In addition, nozzle is located on the casing, is convenient to install, dismantle.
Description of drawings
Fig. 1 is the structural representation of the planet wheel bearing forced lubrication device of the utility model;
Fig. 2 is the structure enlarged diagram of the protruding retaining of ring-type in the utility model.
Embodiment
The embodiment who provides below in conjunction with accompanying drawing does further detailed explanation to the utility model.
Like Fig. 1, shown in 2; A kind of planet wheel bearing forced lubrication device comprises casing 1, planet carrier 4, planetary pinion 5, bearing 6 and planet pin 8, and planet carrier 4 rotational support are on casing 1; Planet pin 8 is contained on the planet carrier 4; Planetary pinion 5 on planet carrier 4, has ring-type protruding retaining 3 on the inner side surface 1-2 opposed inside face 4-1 said planet carrier 4 and casing 1 through bearing 6 rotational support, forms centrifugal collection chamber 9 between the inwall of the inner side surface 4-1 of said planet carrier 4 and the protruding retaining 3 of ring-type; Have oiling road 1-1 on the said casing 1 and be provided with nozzle 2; Oiling road 1-1 communicates with nozzle 2, and the centrifugal collection chamber 9 of the outlet of nozzle 2 on planet carrier 4 has oily passage 8-1 on the said planet pin 8; The import 8-1-1 of oil passage 8-1 communicates with centrifugal collection chamber 9, and the outlet 8-1-2 of oily passage 8-1 leads to bearing 6 places that are positioned at planet pin 8 outsides.
Like Fig. 1, shown in 2, for the ease of the protruding retaining 3 of ring-type is set, the protruding retaining 3 of said ring-type is the rings that are fixedly mounted on the side 4-1 of planet carrier 4.Certainly, the protruding retaining 3 of said ring-type also can be the collar flange with planet carrier 4 one.
Like Fig. 1, shown in 2, for the ease of collecting from the oil of nozzle 2, the protruding retaining 3 of said ring-type has towards the reducing of the inner side surface 1-2 direction of casing 1.
As shown in Figure 1, for the ease of the oily passage 8-1 on the processing planet pin 8, the oily passage 8-1 on the said planet pin 8 is the axial blind hole of the open the other end sealing of an end, and the outlet 8-1-2 of oily passage 8-1 is positioned on the circumferential surface of planet pin 8 and has a plurality of.
