Abstract
The utility model discloses a synchronous aerogenerator of permanent magnetism is to dragging experimental transmission structure, including two generators, still include the frock dummy shaft, rise tight cover and universal shaft coupling, two generators keep the symmetry of interval to install on test platform, and the driving flange side of two generators sets up in opposite directions, the frock dummy shaft has two to adopt the driving flange cooperation of tang complex mode and two generators to be connected respectively, the tight cover that rises is all installed to the tip in opposite directions of two frock dummy shafts, realizes the regulation of the transmission torque value between the frock dummy shaft and the tight cover that rises through the adjusting bolt that rises on the tight cover, two rise and be connected with the universal shaft coupling between the tight cover, and every tight cover that rises adopts the end face tooth to be connected with the universal shaft coupling. The utility model discloses can effectively solve the generator and lead to the fact the problem of generator vibration to dragging the misalignment of two generators in the experiment.
Description
Technical Field
The utility model belongs to the technical field of the synchronous aerogenerator of permanent magnetism's technique and specifically relates to indicate a synchronous aerogenerator of permanent magnetism to dragging experimental transmission structure.
Background
The megawatt permanent magnet synchronous wind driven generator has the advantages that due to the fact that the rotating speeds are numerous and the difference is large, a general generator test platform is not provided with a special test prime motor, but two identical generators are adopted for carrying out generator type tests in a dragging mode, due to the structural particularity of the generators, the generators are not provided with transmission rotating shafts, and the input torque of the generators is directly input to a generator rotor through a generator transmission flange. Whether two generators are centered or not during installation during the generator type test directly influences the generator vibration during the test, and even can cause adverse effects on a generator bearing when the generator type test is serious.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art not enough, provide a synchronous aerogenerator of permanent magnetism to dragging experimental transmission structure, can effectively solve the generator and to dragging the problem that two generators do not the centering in the experiment and cause the generator vibration.
In order to achieve the above object, the present invention provides a technical solution: the utility model provides a synchronous aerogenerator of permanent magnetism drags experimental transmission structure, includes two generators, still includes frock dummy shaft, tight cover and universal shaft coupling that rises, two generator symmetries install on test platform, and the driving flange side of two generators sets up in opposite directions, the frock dummy shaft has two to adopt tang complex mode and the driving flange cooperation of two generators to be connected respectively, the tight cover that rises is all installed to the tip that two frock dummy shafts are opposite, realizes the regulation of the transmission torque value between frock dummy shaft and the tight cover that rises through the adjusting bolt that rises on the tight cover, is connected with universal shaft coupling between two tight covers that rise, and every tight cover that rises adopts the end face tooth to be connected with universal shaft coupling.
Compared with the prior art, the utility model, have following advantage and beneficial effect:
when two engines of the transmission structure for the drag test are installed, the transmission flange is installed in a side opposite direction, the length of the tool dummy shaft can be reduced, the overall length of the whole transmission structure is shortened, the influence of the decentration of the shafts of the two generators during the installation is reduced, the centering requirement on the transmission structure is reduced, and the tool dummy shaft and the generators are positioned and installed by adopting spigot fit, so that the coaxiality of the two generators after the installation is ensured, and the problem of the vibration of the generators during the drag test is effectively avoided; and meanwhile, the tensioning sleeve and the universal shaft coupler are connected through end face teeth, larger torque can be transmitted, the tool dummy shaft and the tensioning sleeve do not need to be detached when being disassembled and installed, and only the tensioning sleeve and the universal shaft coupler need to be separated, so that the operation is more convenient.

Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be further described with reference to the following specific embodiments.
As shown in fig. 1, the drive structure for the drag test of the permanent magnet synchronous wind power generator in this embodiment includes two generators 1, a dummy shaft 2, a tension sleeve 3 and a universal shaft coupler 4, the two generators 1 are symmetrically arranged on the test platform, the transmission flange sides of the two generators 1 are oppositely arranged, the tool dummy shafts 2 are provided with two, and are respectively connected with the transmission flanges of the two generators 1 in a matching way by adopting a spigot, the opposite end parts of the two tooling false shafts 2 are respectively provided with a tensioning sleeve 3, an adjusting bolt on the tensioning sleeve 3 is screwed down to a specified torque value, so as to adjust the transmission torque value between the tool false shaft 2 and the tensioning sleeves 3, a universal shaft coupler 4 is connected between the two tensioning sleeves 3, and each tensioning sleeve 3 and the universal shaft coupler 4 are connected by end face teeth 5, so that transmission of larger torque can be realized.
The above-mentioned embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so that all the changes made according to the shape and principle of the present invention should be covered within the protection scope of the present invention.
