Abstract
The utility model relates to a planet speed increaser, and particularly relates to a wind driven generator gear box adopting a flexible shaft planet mechanism, belonging to the field of speed reducers. A first level planet adopts the flexible shaft planet mechanism, so as to increase the reliability; the flexible shaft planet mechanism can be automatically adapted to the unpredictable transformation, so as to better adaptive to impact load and other moment limit load; the reliability of the whole gear box is enhanced while the flexibility of a system is improved; the maximum dynamic load impact of the whole gear box is reduced by increasing the flexibility of the system; a gear and a bearing are hardly affected by the load, the service life of the gear and the bearing are prolonged; the manufacturing of a key component is simplified; and the assembling of the whole machine is simplified and the high quality is ensured.
Description
Technical field
The utility model relates to a kind of planet booster engine, relates in particular to a kind of wind-driven generator wheel-box that adopts the flexible shaft planetary mechanism, belongs to the speed reducer field.
Background technique
Epicyclic gearbox is the important component part of wind-driven generator, the planetary reduction gear box that traditional wind-driven generator uses, its main shaft and first order planet adopt and are rigidly connected, because the distortion of first order planetary system can not be calculated to a nicety, it relates to the loading of six-freedom degree, be difficult to adapt to the complex load operating mode, be difficult to carry out gear modification, dynamic load causes that easily planet wheel bearing lost efficacy.
Summary of the invention
Because the defective that existing procucts exist, this use is novel to be that a kind of wind-driven generator wheel-box that adopts the flexible shaft planetary mechanism will be provided, its main shaft and first planet carrier adopt and flexibly connect, and to reach the flexibility of raising system, strengthen the purpose of the reliability of whole gear-box.
To achieve these goals, technical solution of the present utility model is: a kind of wind-driven generator wheel-box that adopts the flexible shaft planetary mechanism, and it mainly comprises: casing, main shaft, first order planet, first order sun gear, second level sun gear, second level planet, third level parallel axes and output shaft; Main shaft is positioned at box house, the clutch shaft bearing and the second bearings main shaft; Main shaft is connected with the biography first order phase of planets by spline; First planet is meshed with first order sun gear, first sun gear and the engagement of the second level phase of planets, and second planet is meshed with second sun gear, and second level sun gear passes and is connected with third level parallel axes, and the 3rd parallel axes is connected with output shaft by spline; It is characterized in that: first planet adopts the flexible shaft planetary mechanism.
Advantage of the present utility model is: first order planet adopts the flexible shaft planetary mechanism to increase reliability; The flexible shaft planetary mechanism can adapt to uncertain distortion automatically, adapt to better impulsive load and other moment limit load; By improving the flexibility of system, strengthen the reliability of whole gear-box; By improving the flexibility of system, reduce the maximum dynamic load influence of the whole gear-box of wheel; Gear and bearing are subjected to less load influence, make the life-span prolong; Simplified the manufacturing of critical component; Simplify the assembling of complete machine, guaranteed high quality.
