Abstract
The utility model relates to a planet carrier in a gearbox of a wind driven generator. The planet carrier in the gearbox of the wind driven generator comprises a front panel plate and a rear panel plate. The planet carrier is characterized in that the front panel plate and the rear panel plate are connected through stand columns which are evenly distributed, the number of the stand columns is identical to that of planet wheel shafts, each stand column is located between the corresponding adjacent planet wheel shafts, protruding oil mixing steps are arranged on the periphery of the front panel plate and the periphery of the rear panel plate, and the oil mixing steps are located on the opposite sides, close to the edge of the front panel plate and the edge of the rear panel plate, of the front panel plate and the rear panel plate.
Description
Technical field
The utility model relates to a kind of planet carrier, the planet carrier in especially a kind of wind-driven generator wheel-box.
Background technique
Wind-power electricity generation is compared with traditional thermal power generation, there is the free of contamination advantage of power generation process, compare with hydroelectric power, have that capital construction cost is low, floor space is little, maintaining is advantage easily, especially large-scale hydroelectric power plant, storage reservoir also easily causes certain potential safety hazard to downstream, therefore becomes a kind of environment protection type energy of wideling popularize.At the gear-box of wind-driven generator, generally adopt planetary gear train, and planet carrier is the critical component in planetary gear train.In use, we find, the load of bearing due to planet carrier in gear-box is very large, cause this volume of part to increase, thereby gear-box overall dimensions is strengthened, and have increased cost.In addition,, because gear-box slow speed turbine stage carrying is very large, how to optimize that planet wheel is lubricated also just seems particularly important.
Model utility content
The purpose of this utility model is: for the stressed size that causes of planet carrier in traditional wind power generation gear case, increase, and low speed carrying needs to optimize the lubricated needs of planet wheel more, the planet carrier in a kind of wind-driven generator wheel-box is provided.
The purpose of this utility model is achieved in that the planet carrier in a kind of wind-driven generator wheel-box, comprise front former and rear former, it is characterized in that: front and back former connects by equally distributed column, the quantity of column is consistent with planet wheel shaft, each column is between adjacent lines spider gear shaft, before and after former periphery be equipped with projection stir tank deck rank, stir on the front and back former opposing side at tank deck component level former edge before and after closing on.
In the utility model, described column is solid column, and the column diameter of section that is positioned at front former connecting part is greater than the column diameter of section that is positioned at back panel plate connecting part.
The utility model has the advantage of: owing to adopting the column tilting to connect between former before and after planet carrier, improved the force environment of planet carrier, promoted the bearing capacity of planet carrier, can also dwindle planet carrier axial dimension simultaneously; Because the former connecting part transversal diameter of column before planet carrier is greater than the transversal diameter of back panel plate connecting part column, reduced the cross section of stressed little rear former end column, optimized processing cost; Due on planet carrier former with stirring tank deck rank, in work, planet wheel can obtain better lubricated; Because column between planet carrier former is solid, to process conveniently, mechanical strength is larger.
Accompanying drawing explanation
Fig. 1 be an embodiment of the utility model structural representation;
In figure, 1, front former, 2, stir tank deck rank, 3, column, 4, rear former.
Embodiment
Accompanying drawing discloses the utility model embodiment's concrete structure without limitation, below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the utility model comprises front former 1 and rear former 4, front former 1 is connected by equally distributed column 3 with rear former 4, (planet wheel shaft does not show in the drawings for the quantity of column 3 and planet wheel shaft, lower same) consistent, each column 3 is between adjacent lines spider gear shaft, and what front former 1 and rear former 4 peripheries were equipped with projection stirs tank deck rank 2, stirs tank deck rank 2 and is positioned on the front and back former opposing side that closes on front former 1 and rear former 4 edges.
During concrete enforcement, described column 3 is solid column, and column 3 diameter of sections that are positioned at front former 1 connecting part are greater than column 3 diameter of sections that are positioned at rear former 4 connecting parts.
Claims (2)
1. the planet carrier in a wind-driven generator wheel-box, comprise front former and rear former, it is characterized in that: front and back former connects by equally distributed column, the quantity of column is consistent with planet wheel shaft, each column is between adjacent lines spider gear shaft, before and after former periphery be equipped with projection stir tank deck rank, stir on the front and back former opposing side at tank deck component level former edge before and after closing on.
2. the planet carrier in wind-driven generator wheel-box according to claim 1, is characterized in that: described column is solid column, and the column diameter of section that is positioned at front former connecting part is greater than the column diameter of section that is positioned at back panel plate connecting part.
