Abstract
The utility model relates to a part of a wind power gear box, particularly relates to a novel planetary mechanism of the wind power gear box and belongs to the technical field of machinery. A planet carrier is divided into a front half section and a rear half section. The front half section of the planet carrier is integrally fixed with an input shaft, the interference connection structure of the planet carrier and the input shaft is avoided, connection rigidity is improved, and reliability of a transmission system is improved. The front half section and the rear half section of the planet carrier are connected through a tensioning sleeve and a locking nut, the bolt connection structure is avoided, the bolt connection mode is omitted, the connection strength is improved, and the problem of local stress concentration is solved. Meanwhile, the tensioning sleeve connection mode is adopted, the requirement for manufacturing accuracy of a shaft and a hole is not high, assembly and disassembly are simple, and a user only needs to adjust the tightening degree of a bolt. Further, the tensioning sleeve is long in service life and good in connection rigidity, has good interchangeability and can bear multiple loads.
Description
Technical field
The utility model relates to a kind of wind-powered electricity generation gearbox parts, particularly relates to a kind of novel planetary mechanism of wind-powered electricity generation gear-box, belongs to mechanical equipment technical field.
Background technique
The wind-powered electricity generation gear-box is an important mechanical part in the wind power generating set, and its main function is that the transmission of power that wind wheel produces under the wind-force effect is given generator and made it obtain corresponding rotating speed.Usually the rotating speed of wind wheel is very low, does not far reach the desired rotating speed of generator for electricity generation, must be used for by the speedup of gear-box gear pair realizing.It is driving mechanism that the wind-powered electricity generation gear-box mainly adopts planetary mechanism, and the NW type planetary mechanism that exists is divided into two sections of front and back at present, mainly adopts bolt connecting mode, but this connection Placement, and it is relatively poor that existence connects rigidity, the problem that operational reliability is not good.
Summary of the invention
In view of the defective that prior art exists, the purpose of this utility model is the novel planetary mechanism that a kind of novel wind-powered electricity generation gear-box will be provided, and this planetary mechanism has increased connection rigidity and intensity, the operational reliability excellence.
For achieving the above object, the technical solution that adopts of the utility model:
A kind of novel planetary mechanism of wind-powered electricity generation gear-box, comprise casing, wherein planet carrier is installed on the casing by bearing, and planet wheel shaft is fixedly arranged on the planet carrier, at planet wheel shaft planetary bearing is installed, planet wheel shaft and ring gear engagement, the engagement of planet wheel and sun gear is characterized in that: before and after planet carrier is divided into two sections, planet carrier preceding half section with the input main shaft structure that is fixed as one, power is imported by adpting flange, connects by spline to drive to before the planet carrier half section; Planet carrier is connected with locking nut by tensioner cover with the planet carrier second half section for preceding half section.
Described planet wheel shaft is connected with the planet wheel interference.
After adopting such scheme, the utlity model has following beneficial effect:
Before and after the utility model planet carrier is divided into two sections, planet carrier is solidified as a whole with input shaft for preceding half section, has avoided the interference linkage structure of planet carrier and input shaft, has strengthened the connection rigidity, has improved the reliability of transmission system; Planet carrier is connected with locking nut by tensioner cover with the second half section for preceding half section, avoided bolted structure, the cancellation bolt connecting mode, be conducive to improve join strength, avoid the problem of stress raisers, adopt the Placement of tensioner cover simultaneously, less demanding to the accuracy of manufacturing in axle and hole, install, dismantle simply, a tightness that only needs to adjust bolt gets final product; The long service life of tensioner cover connects good rigidly in addition, has good interchangeability, can bear multiple load simultaneously.
Description of drawings
Fig. 1 is the utility model cross-sectional view.
Among the figure: 1, adpting flange, 2, bearing, 3, casing, 4, preceding half section of planet carrier, 5, the planet carrier second half section, 6, the tensioner cover, 7, locking nut, 8, sun gear, 9, planetary bearing, 10, planet wheel, 11, ring gear, 12, planet wheel shaft.
Embodiment
Specifically describe the utility model below in conjunction with accompanying drawing:
A kind of novel planetary mechanism of wind-powered electricity generation gear-box, as shown in Figure 1, comprise casing 3, wherein planet carrier is installed on the casing 3 by bearing 2, planet wheel shaft 12 is fixedly arranged on the planet carrier, at planet wheel shaft 1 planetary bearing 9 is installed, planet wheel shaft 12 and ring gear 11 engagements, planet wheel 10 and sun gear 8 engagements, it is characterized in that: planet carrier is divided into two sections of front and back, planet carrier preceding half section 4 with the input main shaft structure that is fixed as one, power is by adpting flange 1 input, connects by spline to drive to before the planet carrier half section 4; Planet carrier is connected with locking nut 7 by tensioner cover 6 with the planet carrier second half section 5 for preceding half section 4.
Power is connected by spline by adpting flange 1 input, reaches planet carrier 4,5, drives planet wheel shaft 12 and ring gear 11 engagements, and planet wheel shaft 12 is connected with planet wheel 10 interference, forms the duplex tooth, by planet wheel 10 and sun gear 8 engagements, realizes power output.Before and after planet carrier is divided into two sections, planet carrier is solidified as a whole with input shaft for preceding half section 4, has avoided the interference linkage structure of planet carrier and input shaft, has strengthened the connection rigidity, has improved the reliability of transmission system; Planet carrier is connected with locking nut 7 by tensioner cover 6 with the second half section 5 for preceding half section 4, avoided bolted structure, the cancellation bolt connecting mode, be conducive to improve join strength, avoid the problem of stress raisers, adopt the Placement of tensioner cover 6 simultaneously, because less demanding to the accuracy of manufacturing in axle and hole, therefore its installation, dismounting are simple, and a tightness that only needs to adjust bolt gets final product; The long service life of tensioner cover 6 connects good rigidly in addition, has good interchangeability, can bear multiple load simultaneously.
