Definitions
- the invention relates to a transmission according to the preamble of claim 1.
- So-called back-to-back test benches for wind power transmissions are known from the prior art.
- a back-to-back test stand two test pieces are compared with each other and coupled with their input shafts rotationally fixed.
- a motor drives the output shaft of a test object.
- the output shaft of the other test object is coupled to a generator.
- the types and dimensions of the samples may vary. Therefore, it is necessary to design the motor and the generator both vertically and horizontally movable. Serve with elaborate platforms on which the engine and the generator are mounted. The platforms have a significant share in the cost price of such a test bench.
- the invention has for its object to eliminate the inherent disadvantages of the prior art solutions disadvantages.
- a test stand for wind turbine gear is to be made available, which is inexpensive.
- the transmission has a rotatable structure, a first shaft and a second shaft.
- the structure is preferably rotatable about an arbitrary angle about exactly one axis of rotation, if appropriate also several axes of rotation.
- the angle can be in particular at least 360 °.
- the first shaft and the second shaft are kinematically coupled.
- the waves are inevitable, ie coupled to a transmission degree of freedom of 1.
- a general definition of the term transmission degree of freedom, also called gear ratio, can be found in "Dubbel” (K.-H. Grote, J. Feldhusen: “Dubbel", 22nd Edition 2007).
- the first shaft and the second shaft are each an input or output shaft. Either the first shaft is an input shaft and the second shaft is an output shaft, or the first shaft is an output shaft and the second shaft is an input shaft.
- Input and output shafts are characterized by the fact that they protrude from a housing of the transmission and are accessible from the outside, so that they can be rotatably connected to other shafts or rotatable components.
- the input shaft serves to introduce a torque into the transmission.
- the output shaft serves to direct a torque out of the transmission. In this way, a torque flux running from the input shaft to the output shaft is established.
- the first shaft and the second shaft are rotatably mounted in the rotatable structure.
- the first shaft and the second shaft are rotatable relative to the rotatable structure.
- a rotation axis of the first shaft and a rotation axis of the rotatable structure are identical. A rotation of the first shaft and a rotation of the rotatable structure thus takes place about a common axis of rotation. As a result, upon rotation of the rotatable structure, the position of the first shaft remains unchanged.
- the second wave is arranged eccentrically with respect to the rotatable structure.
- An axis of rotation of the second shaft, however, and the axis of rotation of the rotatable structure are thus spaced apart. This means that the axis of rotation of the second shaft and the axis of rotation of the rotatable structure do not intersect.
- the axis of rotation of the second shaft and the axis of rotation of the rotatable structure are not identical.
- both axes of rotation are parallel to each other.
- the eccentric arrangement of the second shaft causes the axis of rotation of the second shaft in a circular path upon rotation of the rotatable structure whose axis of rotation moves.
- the transmission has in a preferred embodiment, a first gear and a second gear, which mesh with each other.
- the first gear is rotatably connected to the first shaft, the second gear rotatably connected to the second shaft.
- the transmission can be developed with a third wave.
- the third wave is also an input or output wave.
- the third wave is the same kind as the second wave. If the second shaft is an input shaft, the third shaft is also designed as an input shaft. Conversely, the third is formed as an output shaft when the second shaft is an output shaft.
- the third shaft is rotatably mounted in the rotatable structure and arranged eccentrically with respect to the rotatable structure.
- An axis of rotation of the third shaft and the axis of rotation of the rotatable structure are thus spaced from each other.
- the axis of rotation of the third shaft preferably runs parallel to the axis of rotation of the rotatable structure.
- the third wave multiplies the configuration possibilities of a test bench set up with the transmission.
- the third wave is integrated in the transmission in a preferred embodiment via a third gear, which is rotatably connected to the third shaft.
- the third gear meshes with the first gear or with the second gear.
- a first part of a housing of the transmission forms the rotatable structure.
- the first part is rotatably mounted in a second part of the housing.
- a housing of a transmission is generally called a shell which encapsulates the other components of the transmission.
- the different from the housing components of the transmission are located at least partially inside the transmission.
- the shafts of the transmission are mounted in the housing.
- the transmission according to the invention and its preferred developments are suitable for use in a transmission test bench.
- a corresponding arrangement for testing a transmission - a first transmission test object - has a first transmission.
- the first transmission is an inventive transmission or a preferred development.
- An input or output shaft of the first Gereteprüflings is rotatably connected to the second shaft, if present, connectable to the third shaft of the first transmission.
- the arrangement is further developed by a drive with a drive shaft and / or an output with an output shaft.
- the drive shaft or the output shaft is rotatably connected to the first shaft of the first transmission.
- the position of the second shaft and, if present, the third shaft can now be adapted to the structural conditions of the first transmission test object, so that its input or output shaft is connected in a rotationally fixed manner to the second shaft or possibly the third shaft of the first transmission can be.
- the arrangement comprises at least one horizontal movable platform.
- the platform can be moved or moved translationally in the horizontal direction.
- the first gear and / or the drives and / or the output are fixed to the platform, preferably on the platform. With the platform thus also the first gear and / or the drive and / or the output are horizontally movable. In this way, the horizontal positioning of the second wave can be optimized.
- the arrangement is preferably further developed as a back-to-back test stand for receiving a second transmission test object.
- the first Geretegprüfling and the second Geretegprüfling are identical. So it's about identical gearbox.
- Two components are identical if they match in their physical parameters - especially in terms of their material and geometry properties - within the scope of manufacturing tolerances.
- the input shaft of the first transmission test specimen and an input shaft of the second transmission test specimen are rotatably connected to each other.
- the output shaft of the first transmission test object is connected in a rotationally fixed manner to the second shaft or, if present, to the third shaft of the first transmission.
- the position of the second shaft or possibly the third shaft of the first transmission is adjusted by rotating the rotatable structure of the first transmission and optionally the platform.
- the second Gerete Sammlungprüfling is involved in a preferred development of an inventive transmission in the test bed.
- a corresponding arrangement comprises a second transmission with the features of the invention.
- the first gear and the second gear are identical.
- Rotationally connected to the first shaft of the first transmission is further development according to the drive shaft of the drive.
- the output shaft of the output is rotatably connected to the first shaft of the second transmission.
- Fig. 1 a transmission
- FIG. 2 shows a drive of a test bench; 3 shows the range of motion of an output shaft of the transmission; and FIG. 4 shows a positioning mechanism.
- a transmission 101 according to FIG. 1 has a first shaft 103, a second shaft 105 and a third shaft 107. Furthermore, three gears are present - a first gear 109, a second gear 111 and a third gear 113.
- the first gear 109 is rotatably fixed on the first shaft 103, the second gear 111 on the second shaft 105 and the third gear 113 on the third shaft 107.
- the second gear 111 meshes with both the first gear 109 and the third gear 113.
- a housing 115 of the transmission 101 is constructed in several pieces. It comprises a body 117 and a rotatable part 119. In the rotatable part 119, the first shaft 103, the second shaft 105 and the third shaft 107 are rotatably supported. For this purpose, rolling bearings 121 are embedded in the rotatable part 119.
- the rotatable part 119 of the housing 115 in turn is rotatably mounted in the hull 117 by means of two rolling bearings 123.
- the rotatable member 119 and the first shaft 103 are concentrically arranged so that their axes of rotation correspond.
- a rotation axis of the second shaft 105 and a rotation axis of the third shaft 107 are spaced apart from the rotational axis of the first shaft 103. This causes the second shaft 105 and the third shaft 107 to rotate upon rotation of the rotatable member 119 of the housing 115 move in a circular orbit about the first shaft 103 and its axis of rotation.
- the rotatable part 119 of the housing 115 has two disk-shaped side parts 125.
- the side parts 125 are connected to each other by axially extending transverse struts 127.
- the bearings 121 are embedded with which the shafts 103, 105, 107 are mounted.
- each ring gear 129 engages a - not shown in Fig. 1 - a pinion.
- the pinions are driven by a motor mounted in the rotatable part 119 of the housing 115. In this way, the rotatable member 119 can be rotated.
- FIG. 2 illustrates part of a test stand 201 comprising the transmission 101 shown in FIG.
- the hull 117 of the housing 115 of the transmission 101 is fixed on a platform 203.
- a motor 205 is fixed on the platform 203.
- An output shaft 207 of the motor 205 is rotatably connected to the first shaft 103 of the transmission 101.
- the test stand 201 has a mechanism with which the platform 203 can be moved biaxially in the horizontal direction.
- the arrangement shown in FIG. 2 may comprise a generator whose input shaft is non-rotatably connected to the first shaft 103 of the transmission 101.
- a back-to-back test stand an arrangement according to FIG. 2 and an arrangement with a generator are positioned opposite one another.
- a positioning region 301 of one of the two eccentrically arranged shafts 105, 107 is illustrated in FIG. 3.
- the positioning region 301 is covered by superposing a horizontal movement of the platform 203 and a rotation of the rotatable part 119.
- a mechanism for rotating the rotatable member 119 is shown in Fig. 4.
- the mechanism has two screws 401 which engage with a worm wheel 403 to form a worm gear.
- the worm wheel 403 and the rotatable part 119 of the housing 115 are rotatably connected to each other.
- a central axis of the worm wheel 403 corresponds to the axis of rotation of the rotatable part 119.
