Description
Technical field
The present invention relates to the testing apparatus of yaw drive for wind-driven generator and variable pitch driver, in more detail, relate to the tooth bar that a kind of rotary motion be provided with for carrying out the yaw drive of testing property or the carry-out part of variable pitch driver is transformed to straight line motion, and on described tooth bar, connecting the wind-driven generator yaw drive of oil hydraulic cylinder and the testing apparatus of variable pitch driver that this tooth bar are applied to load, this testing apparatus structure is simple, generation noise is little, can make shared space-minimized yaw drive variable pitch driver in working site.
Background technique
In general, wind-driven generator is the device of electric energy by Wind resource change, makes the blade rotary of wind-driven generator, generated electricity by the rotating force of the blade now produced.Wind-driven generator is the device of electric energy by the transformation of energy entrained by wind.That is, wind makes the blade of wind-driven generator rotate, and can be generated electricity by the rotating force of the blade now produced.
This kinetic energy used in wind-driven generator can not emission matter compared with utilizing the energy of the fossil fuel such as oil, coal, due to the fossil fuel not using reserves limited, therefore without the need to worrying resource exhaustion, compared with the nuclear energy that the possibility flowed out with radioactivity is high, because use natural energy resources, so its stability is high and favored as green energy resource.
The wind-driven generator of wind is utilized roughly to comprise as above: the pylon being fixed on ground; Be arranged on the cabin (NACELLE) of the upper end of described pylon, this cabin is provided with generator etc.; And by the blade that axle is connected with the generator in described cabin, this blade is rotated by wind.
Particularly, in wind-driven generator as above, for the direction making cabin that wind can be coordinated is carried out rotating and improved generating efficiency, pylon and cabin are provided with yaw drive (YAWDRIVE), and are provided with the variable pitch driver (PITCHDRIVE) of the angle regulating each blade in described cabin.
Particularly, described yaw drive and variable pitch driver roughly comprise: the input part as drive motor or actuating motor etc. by transformation of electrical energy being rotary motion; Reduction part, this reduction part is used for the rotating force provided by described input part to be transformed to suitable rotation number; And carry-out part, this carry-out part rotates cabin or blade by the rotating force via described reduction part.
About the yaw drive and the variable pitch driver that are arranged on the wind-driven generator with structure described above, because the direction and intensity of wind can there are differences according to the arranging environment of wind-driven generator, so need to use the strong yaw drive of serviceability and variable pitch driver could reduce the replacing in using and maintenance.
Therefore, before yaw drive and variable pitch driver are loaded in wind-driven generator, need the test process carrying out the performance testing yaw drive and variable pitch driver.For this reason, load can be produced to yaw drive and variable pitch driver constantly in the past and carry out yaw drive or variable pitch driver rotate forward and counterrotating loop around test, absorb rated torque 120% accelerated life test, driving torque monitoring and record, now, for making to produce load in yaw drive or variable pitch driver, check performance by the testing apparatus being provided with solid of rotation, this solid of rotation corresponds to the yaw drive or variable pitch driver that will test.
But, testing apparatus in the past as above needs the solid of rotation corresponding with the yaw drive that will test or variable pitch driver to be arranged on yaw drive variable pitch driver on testing apparatus, therefore, when testing the different yaw drive of specifications and characteristics or variable pitch driver, have the inconvenience needing to arrange the solid of rotation corresponding with it on testing apparatus.
Particularly, for test yaw drive or variable pitch driver and the solid of rotation that is arranged on testing apparatus has the structure similar to the yaw drive that will test or variable pitch driver, therefore, not only its Heavy Weight and be not easy the replacing operation carrying out solid of rotation, but also deposit the problem producing noise at work.
In addition, because the solid of rotation being arranged on testing apparatus has the structure similar to yaw drive or variable pitch driver, so the space that its volume makes greatly testing apparatus shared in working site is large, therefore, the problem that the space utilization that there is working site is restricted.
