Fig. 1 is a transmission device schematic representation of the present invention.
Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1, automatic speed regulation, the smooth rate apparatus that is used for wind-power generating system of the present invention comprises actuating motor 15, planetary gear mechanism, infinitely variable speed gearing, electric spiral driving mechanism.
Planetary gear mechanism is by planet carrier 3, internal gear 4, and planetary pinion 19, sun gear 20 are formed; Infinitely variable speed gearing is by cone pulley 8, cone pulley 13, and 14, two adjustment (adjusting) levers of left and right sides screw pair 6 are formed; The electric spiral driving mechanism is by left and right sides screw pair 14, and actuating motor 15 is formed; Wherein, planetary pinion 19 meshes with sun gear 20 and internal gear 4 simultaneously, sun gear 20 and two cone pulleys, 8 coaxial being installed on the input shaft 9 that are movably connected in respectively on two adjustment (adjusting) levers 6, be movably connected in two cone pulleys, 13 coaxial being installed on the output shaft 18 on two adjustment (adjusting) levers 6 respectively, be in transmission connection by toothed belt 7 between cone pulley 8 and the cone pulley 13; Left and right sides screw pair 14 is connected with two adjustment (adjusting) levers 6 respectively, and links to each other with actuating motor 15.
Planetary pinion 19, sun gear 20 and internal gear 4 form typical planetary gear mechanism; Be installed in a pair of cone pulley 8 on the input shaft 9, be installed in a pair of cone pulley 13 on the output shaft 18, toothed belt 7, left and right sides screw pair 14, two adjustment (adjusting) levers 6 form typical infinitely variable speed gearing; On left and right sides screw pair 14, connect actuating motor 15, form the electric spiral transmission through coupling 16.Above-mentioned three kinds of drive are combined, just constituted the automatic speed regulation, the smooth rate apparatus that are applicable to wind-power generating system.
Blade 1 links to each other with planet carrier 3 with coupling 2 by wheel hub, main shaft.When blade 1 drove planet carrier 3 rotations, planet carrier 3 drove planetary pinion 19 and does planetary motion.Because planetary pinion 19 meshes with sun gear 20 and internal gear 4 simultaneously, and internal gear 4 belongs to external gear 5 and fixedlys connected, external gear 5 and external gear 17 engagements, pass through toothed belt 7 transmissions between cone pulley 8 and the cone pulley 13, has fixing velocity ratio relation, therefore, when the cone pulley 8 and velocity ratio (ratio of a pitch diameter) timing that is installed in the cone pulley 13 on the output shaft 18 that are installed on the input shaft 9, between external gear 17 and sun gear 20, applied the velocity ratio restriction relation, made output shaft 18 drive generator 12 rotations by coupling 11.
When transmission device was worked, power circuit was made of two-way.One road power via impeller 1, planet carrier 3, planetary pinion 19, internal gear 4, external gear 5, external gear 17, transmission shaft 18, one road power via impeller 1, planet carrier 3, planetary pinion 19, sun gear 20, input shaft 9, cone pulley 8, toothed belt 7, cone pulley 13, output shaft 18.Power circuit is delivered to generator 12 by coupling 11 after converging on the output shaft 18.Because this transfer unit has the power dividing function, therefore, the power of the toothed belt 7 of flowing through is far below the actual power of wind power generating set, therefore, the requirement of strength of toothed belt reduced greatly.
When actuating motor 15 rotations, left and right sides screw pair 14 drives 6 swings of two adjustment (adjusting) levers simultaneously, drive cone pulley 8 and cone pulley 13 slip on input shaft 9 and output shaft 18 respectively by the slide block that is connected adjustment (adjusting) lever 6 two ends, thereby adjust the contact position of toothed belt 7 on cone pulley 8 and cone pulley 13, also just adjusted the pitch diameter of cone pulley 8 and cone pulley 13, the velocity ratio of input shaft 9 and output shaft 18 is changed.Left and right sides screw pair 10 is used for adjusting the tension force and the degree of tightness of toothed belt 7.
If the number of teeth of sun gear 20 is z
a, the number of teeth of planetary pinion 19 is z
g, the number of teeth of internal gear 4 is z
b, the number of teeth of external gear 5 is z
B ', the number of teeth of external gear 17 is z
c, the pitch diameter of cone pulley 8 is D on the input shaft 9
1, the pitch diameter of the cone pulley 13 on the output shaft 18 is D
2, then this transmission device has following velocity ratio relation:
i
HLIt is exactly the speed ratio between wind wheel 1 and the generator 12.By the pitch diameter of actuating motor 15 adjusting cone pulleys 8 and cone pulley 13, just can regulate velocity ratio i
pThereby, regulated the speed ratio i between wind wheel 1 and the generator 12
HL, reached the purpose of automatic speed regulation.
