The model utility content
The technical problem that the utility model will solve is the deficiency that overcomes existing technology, provides a kind of parameter value scope to satisfy the non-planet wheel decelerator that is uniformly distributed with that is used for wind power generating set of retarder velocity ratio, size and requirement of strength more extensively, more easily.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of non-planet wheel decelerator that is uniformly distributed with that is used for wind power generating set; Comprise the multistage planet wheels; Planetary gear set at different levels comprise a sun gear, a plurality of planet wheel and a ring gear; Having the one-level planetary gear set at least is the non-planetary gear set that is uniformly distributed with, and the said non-non-homogeneous periphery that is arranged in sun gear of a plurality of planet wheels that is uniformly distributed with in the planetary gear set, each planet wheel all mesh with sun gear and ring gear.
Said non-being uniformly distributed with in the planetary gear set; If the rotating center of the rotating center of each planet wheel and an adjacent lines star-wheel is θ 1 to the line angle of the rotating center of sun gear; If the rotating center of the rotating center of each planet wheel and another adjacent lines star-wheel is θ 2 to the line angle of the rotating center of sun gear, then θ 1 ≠ θ 2.
Said non-being uniformly distributed with in the planetary gear set, the rotating center of establishing adjacent two planet wheels is θ to the rotating center angle of sun gear, the total quantity of planet wheel is N; θ `=360 °/N; The number of teeth of sun gear is Za, and the number of teeth of ring gear is Zb, then 0＜| θ-θ `|≤360 °/(Za+Zb).
Said non-total quantity N >=4 that are uniformly distributed with the planet wheel 2 in the planetary gear set o'clock; A plurality of planet wheels divide into groups to be provided with; And quantity M >=2 of planet wheel in each group, the angle between the two adjacent groups planet wheel is organized the angle theta that rotating center became of the rotating center of adjacent two planet wheels in planet wheel to sun gear greater than each.
Compared with prior art, the advantage of the utility model is:
The non-planet wheel decelerator that is uniformly distributed with that is used for wind power generating set of the utility model; Adopt the non-structure that is uniformly distributed with planetary gear set; With the non-homogeneous periphery that is arranged in sun gear of a plurality of planet wheels; This make the sun gear number of teeth, the ring gear number of teeth and planet wheel number to choose scope wideer, thereby satisfy velocity ratio, size and the requirement of strength of wind power generating set more easily to this type of retarder.When the non-total quantity N that is uniformly distributed with planet wheel in the planetary gear set >=4; Can a plurality of planet wheels be divided into groups to be provided with; And quantity M >=2 of planet wheel in each group; Angle between the two adjacent groups planet wheel is organized the angle theta that rotating center became of the rotating center of adjacent two planet wheels in planet wheel to sun gear greater than each, can improve the strength and stiffness of planet carrier connecting tendon so to greatest extent.
