Definitions
- the present invention relates to a high efficiency torque transmission device, in particular for an eohenne
- an eohenne consists of a tower carrying at its top a movable head according to the orientation of the wind on which are mounted blades, free to rotate under the influence of the wind, intended to provide a torque, i.e. a certain driving force in rotation to a transmission shaft connected to a multiplier in order to increase this torque before being transmitted to a generator
- the object of the invention is to propose a high-efficiency torque transmission device for an eohenne which makes it possible to solve all or part of the aforementioned drawbacks, in particular a device capable of transmitting high torque without inducing excessive stresses in the various links. drive
- the subject of the present invention is a high-efficiency torque transmission device, in particular for an eohenne, comprising an envelope mounted to rotate freely around a support beam on which the blades of the wind turbine are fixed and inside which is housed a mechanism for multiplying the nominal speed of said blades which cooperates on the one hand with the casing and on the other hand with the output shaft intended to be coupled in particular to a generator, characterized in that the envelope is mounted to rotate freely around the support beam by means of a tapered bearing disposed at each end of the envelope, said envelope resting on the outer ring of the bearings
- a high-efficiency torque transmission device in particular for an eohenne, comprising an envelope freely mounted in rotation around a support beam on which the blades of the wind turbine are fixed and to the inside which is housed a mechanism for multiplying the nominal speed of said blades which cooperates on the one hand with the casing and on the other hand with the output shaft intended to be coupled in particular to a generator, characterized in
- this mechanism consists of at least one planetary gear train comprising three satellites spaced angularly in a regular manner and each carried by a shaft parallel to the output shaft on which is mounted a driving pinion which meshes with a pinion integral with said output shaft,
- the casing is mounted to rotate freely around the support beam by means of a tapered bearing disposed at each end of the casing
- the multiplication mechanism advantageously consists of a succession of at least three planetary gear trains, preferably four,
- each of the support shafts of the planetary gear trains is fixed to the support beam
- the drive ring is produced by internal machining of the casing
- Another object of the present invention relates to an eohenne characterized in that it comprises a torque transmission device conforming to any of the characteristics mentioned above
- FIG. 1 is a side view of the head of an eohenne provided with the device according to the invention
- FIG. 2 is a partial section view of the device according to the invention.
- FIG. 3 is a sectional view along the line III-III of FIG. 2,
- FIG. 4 is a sectional view along line IV-IV of FIG. 2,
- FIG. 5 is a sectional view along the line V-V of FIG. 2, and
- FIG. 6 is a sectional view along line VI-VI of Figure 2
- This device 2 comprises a casing 3 mounted to rotate freely around a support beam 4 by means, for example, of a tapered bearing C disposed at each end of the latter, and a speed multiplication mechanism 5 nominal of the blades 1 which is connected to an output shaft 6 and housed inside said casing
- This output shaft 6, also designated drive shaft, is conventionally coupled to a generator, not shown, disposed in the movable head of wind
- the casing 3 is provided at its outer periphery with fastening means 7 for the blades 1 and at its internal periphery with a drive ring 8, as visible in FIG. 2, which is coupled with the mechanism multiplication 5 thus forming the input ring of the torque to be transmitted to the generator, this torque is formed by the recovery of the induced rotary movement of the blades of the wind turbine
- the drive ring is advantageously made by internal machining of the casing 3
- the multiplication mechanism 5 consists of a succession of four planetary gear trains T1, 12,
- the first tram T1 as visible in FIG. 3, meshes with the drive ring 8 and the last train T4 meshes with a pinion 9 secured to the output shaft 6
- this output shaft 6 is arranged coaxially inside the support beam 4 thus offering a reduced bulk to the device according to the invention. Furthermore, this support beam 4 supports each planetary gear tram, as visible in Figure 1, thus ensuring by adequate sizing thereof a high resistance
- the drive ring 8 meshes with the first planetary gear tram T1 consisting of three satellites 10 angularly spaced at regular intervals, as visible in FIG. 3, so as to balance the forces on the envelope 3
- the satellite 10 of the first planetary gear T1 is carried by a first shaft 11 parallel to the output shaft 6 and meshes on the one hand with the drive ring 8 and on the other hand with a pinion 12 secured to a second shaft 13 also parallel to the output shaft 6
- This second shaft 13 carries, moreover, the driving pinion 14 of the second planetary gear tram T2 which meshes with a driven pinion 15 carried by a third support shaft 16, as visible in FIG. 4
- the third shaft 16 carries the driving pinion 17 of the third planetary tram T3 (FIG. 5) which meshes with a driven pinion 18 carried by a fourth shaft 19 on which is also arranged the driving pinion 20 of the fourth planetary tram T4 which meshes with the single pinion 9 integral with the output shaft 6 ( Figure 6)
- the drive ring can mesh with a satellite of a first planetary gear train mounted on a first shaft also carrying the pinion leading from the second planetary gear train eliminating with respect to the first embodiment an intermediate pinion
- this envelope consists, for example, of an annular part and of two flanges disposed at each end each resting on the outer ring of said tapered bearing, thus offering a simple and inexpensive embodiment of the envelope.
- This simple architecture also makes it possible to support heavy loads on the envelope.
- the device of the present invention is relatively simple to produce and makes it possible to dispense with the blade support of the input shaft of the multiplier and its bearing for supporting the structures. of traditional eohennes This device makes it possible to considerably reduce the head load for high power eohennes It can also be applied to lower power wind systems
