Description
Technical field
Content of the present invention belongs to generating mechanical equipment technical field, relates to a kind of wind-force, hydroelectric power speed increaser.
Background technique
In large scale wind, hydro-generating Unit, speed increaser gear-box is one of link that rate of fault is the highest, is also the Main Bottleneck of wind-force, hydroelectric power equipment Design level.Because the flow velocity of large-scale wind-force, hydro-generating Unit power resources is lower, this just needs the size adding big blade or turbine blade to absorb the power source of low flow velocity, blade as current wind-driven generator can reach about 40 meters, and large-sized water turbine generator blade is also more than 10 meters.But after on the one-level gear that the huge energy absorbing wind-force or waterpower is directly imported into speed increaser by large-scale blades in extremely slow-revving situation, gear will be made will to bear huge moment of torsion, cause gear life greatly to shorten.To lift a power be the wind power generation speed increasing device of 1663KW is example: in the extremely slow-revving situation of blade, the moment of torsion that its one-level gear bears can reach 794KN, this powerful moment of torsion finally acts on the flank of tooth of speed increaser one-level gear, the flank of tooth can be made to produce distortion, distortion, peel off, corrode ... cause gear life greatly to shorten, do not reach designing requirement.
Summary of the invention
The object of the invention is to solve prior art Problems existing, and then a kind of rational in infrastructure, easy to operate, wind-force, hydroelectric power speed increaser that significantly can improve gear usability and working life is provided.
For achieving the above object and adopt technical solution as described below.
A kind of wind-force, hydroelectric power speed increaser, by wind-force or hydraulic impeller, input shaft, planet carrier, line of input star-wheel, one-level sun gear, secondary solar gear, rear planet wheel, input ring gear, export ring gear and output shaft composition, input ring gear and output ring gear are connected and consist of the suspension wheels ring gear of one, one end of input shaft is connected on the wheel of wind-force or hydraulic impeller in the heart, the other end is rigidly connected by the core wheel of planet carrier and line of input star-wheel, one-level sun gear and secondary solar gear are respectively by line of input star-wheel and rear planet wheel and input ring gear and export ring gear and be in transmission connection, one-level sun gear core wheel is connected by a stiff shaft with the core wheel of secondary solar gear, at the wheel of secondary solar gear, the output shaft being communicated to generator is housed in the heart.
In above-mentioned wind-force, hydroelectric power speed increaser, one-level sun gear and secondary solar gear, stiff shaft form a rigid body.
In above-mentioned wind-force, hydroelectric power speed increaser, input ring gear and to export that ring gear connects to form be the suspension wheels ring gear of a rigid body.
In real work, when the blade of wind-driven generator or water turbine is when absorbing wind energy or water can rotate, its energy drives the running of line of input star-wheel by input shaft and planet carrier, owing to driving input ring gear and the running of one-level sun gear while the running of line of input star-wheel, and one-level sun gear and secondary solar gear are by being connected by a stiff shaft, so one-level sun gear and secondary solar gear run-in synchronism; Again because input ring gear and output ring gear constitute a rigid body suspension wheels ring gear, so input ring gear and the run-in synchronism of output ring gear, and export ring gear also by the running of rear planet wheel drive secondary solar gear, so whole speed increaser can make the output shaft being communicated to generator reach design speed according to designing requirement, and then the work of drive electrical generators group.
Wind-force of the present invention, the maximum feature of hydroelectric power speed increaser is that the inner all strength of gear teeth difference of speed increaser is very little, in each gear, tooth loads is substantially identical, to adopt the wind-driven generator of the 1663KW of this structure: when input shaft and planet carrier strength are about the powerful moment of torsion of 794KN, one-level sun gear and secondary solar gear, the strength of all gears (gear ring) on line of input star-wheel and output planetary wheel and suspension wheels ring gear is all about 11.3KN, only 1/70 of input torque, so proposition of the present invention solves the wind-force of current related domain, the key issue of waterpower industry middle gear transmission system development, the reliability that large-scale speed increaser gear-box is used and being obtained for working life significantly promotes.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention's specific embodiment.
In figure, the title of each number designation respectively: 1. wind-force or hydraulic impeller, 2. input shaft, 3. planet carrier, 4. line of input star-wheel, 5. suspension wheels ring gear, 6. one-level sun gear, 7. secondary solar gear, 8. stiff shaft, 9. planet wheel after, 10. inputs ring gear, and 11. export ring gear, 12. output shafts, 13. motors.
Embodiment
See accompanying drawing, wind-force of the present invention, hydroelectric power speed increaser by wind-force or hydraulic impeller 1, input shaft 2, planet carrier 3, line of input star-wheel 4, one-level sun gear 6, secondary solar gear 7, rear planet wheel 9, input ring gear 10, export the part such as ring gear 11 and output shaft 12 and form.Input ring gear 10 and output ring gear 11 are connected and consist of the suspension wheels ring gear 5 of a rigidity, and an end of input shaft 2 is connected on the wheel of wind-force or hydraulic impeller 1 in the heart, and the other end is rigidly connected by the core wheel of planet carrier 3 with line of input star-wheel 4.One-level sun gear 6 is in transmission connection by line of input star-wheel 4 and input ring gear 10, secondary solar gear 7 is in transmission connection by rear planet wheel 9 and output ring gear 11, the core wheel of one-level sun gear 6 is connected by stiff shaft 8 with the core wheel of secondary solar gear 7, and the output shaft 12 being communicated to generator 13 is housed in the heart at the wheel of secondary solar gear 7.
The working principle of this wind-force, hydroelectric power speed increaser is: when wind-force or hydraulic impeller 1 absorb wind energy or water can rotate, its energy drives input planet gear 4 to operate by input shaft 2 and planet carrier 3, owing to driving input ring gear 10 and one-level sun gear 6 to operate while line of input star-wheel 4 running, and the core wheel of one-level sun gear 6 and secondary solar gear 7 is interconnected by stiff shaft 8, so one-level sun gear 6 and secondary solar gear 7 run-in synchronism; Again because input ring gear 10 and output ring gear 11 form a rigid body suspension wheels ring gear 5, so input ring gear 10 and the also run-in synchronism of output ring gear 11, exporting ring gear 11 in addition drives secondary solar gear 7 to operate by rear planet wheel 9, so under the effect of suspension wheels ring gear 5 and rear planet wheel 9, whole speed increaser can make output shaft 12 reach design speed according to designing requirement, works with drive electrical generators 13.
