Abstract
The utility model relates to a low speed stage planet carrier assembly of a yaw variable pitch gear box. The low speed stage planet carrier assembly comprises a planet carrier, pin shafts and planet wheels. The speed stage planet carrier assembly is characterized in that one end of each pin shaft is provided with a flange, the planet carrier is of a double-wall structure, 3-5 pairs of corresponding pin shaft installing holes are evenly distributed in two walls of the planet carrier, the pin shaft installing holes in one wall are provided with pin shaft limiting steps and check ring grooves provided with elastic check rings for the holes, each pair of the installing holes is provided with one pin shaft, and the flanges of the pin shafts butt against the pin shaft limiting steps and are limited by the elastic check rings for the holes in the check ring grooves. The planet wheels are installed on the pin shafts through bearings, and stopping blocks are arranged between the two ends of each bearing and the planet carrier at the two ends of each pin shaft.
Description
Technical field
The utility model relates to a kind of planet carrier assembly, the planet carrier assembly in especially a kind of variable propeller gearbox of going off course.
Background technique
The driftage variable propeller gearbox of wind-driven generator is the vitals of wind-driven generator.Yaw gearbox is used for regulating the cabin and turns to, and variable propeller gearbox is used for regulating the angle of blade, and both actings in conjunction make wind-driven generator can adapt to the variation of wind direction or wind-force, in order to obtain suitable generating wind-force rotating speed.Because operating mode is more abominable, inconvenient maintenance adds that installing space is narrow and small, and the driftage variable propeller gearbox has strict requirement to reliability, weight, boundary dimension.
In traditional driftage variable propeller gearbox design, because the carrying of slow speed turbine stage planet carrier is higher, for the rigidity that guarantees to support, generally adopt double-walled construction.On two walls of described planet carrier, even 3-5 the bearing pin mounting holes that distribute, be furnished with a bearing pin in corresponding a pair of mounting hole, and planet wheel is arranged on planet carrier by bearing pin.The bearing pin two ends must be spacing, runs out from planet carrier under the long term of load preventing.Usually the orientation type of taking is that bearing pin one end is butted on the limited step in the bearing pin mounting hole of a wall of planet carrier, and the other end is stuck in the bearing pin mounting hole of another wall of planet carrier by circlip.
Due to the structure that bearing pin adopts two ends to locate respectively, during installation, planet carrier needs upset, and efficient is low.Simultaneously because carrying is higher, in order to reserve the space, location, the wall thickness of planet carrier two walls there is strict demand.So just limited the appropriate design of planet carrier structure, and the rational deployment of gear-box.
The model utility content
The purpose of this utility model is: in the planet carrier for existing driftage variable propeller gearbox, and the structure that bearing pin adopts two ends to locate respectively, installing needs upset, and efficient is low; All to be strict with the thickness of planet carrier two walls simultaneously, limit the practical problem of planet carrier structure optimal design and gear-box rational deployment, propose a kind of new bearing pin positioning means that is used for driftage variable propeller gearbox planet carrier.
The purpose of this utility model is achieved in that the planet carrier assembly in a kind of variable propeller gearbox of going off course, comprise planet carrier, bearing pin and planet wheel, it is characterized in that: described bearing pin one end band rib, described planet carrier is double-walled construction, the bearing pin mounting hole of 3-5 pairs of correspondences that evenly distribute on two walls of planet carrier, wherein be provided with bearing pin limited step and the circlip groove of being furnished with circlip for hole in the mounting hole on a wall, is furnished with a bearing pin in every pair of mounting hole, the rib of bearing pin is butted on the bearing pin limited step, and spacing by the circlip for hole in circlip groove; Planet wheel is arranged on bearing pin by bearing, is equipped with block between the two ends of bearing and pivot pin two ends planet carrier.
In the utility model: planet wheel is arranged on bearing pin by two bearings arranged side by side, is provided with back-up ring between two bearings, is equipped with block between the outside of two bearings and pivot pin two ends planet carrier.
In the utility model: be provided with oil leab in bearing pin, the back-up ring position between the terminal of oil leab and two bearings is corresponding.
The utility model has the advantage of: because bearing pin adopts monolateral position structure, during installation, planet carrier does not need upset, and efficient is high.The side thickness that the while planet carrier need to be located increases, and rigidity is strengthened; And a side that does not need to locate need not be reserved the space, location, and wall thickness reduction is for the optimal design of planet carrier structure and the rational deployment of gear-box provide new thinking.
