Problems solved by technology

[0009] However, the conventional test device as described above needs to install a rotating body corresponding to the yaw drive or the pitch drive to be tested on the test device. In the case of testing the drive or pitch drive, it is inconvenient to install a corresponding rotating body on the test device
[0010] In particular, the rotating body installed in the test device for testing the yaw driver or the pitch driver has a structure similar to that of the yaw driver or the pitch driver to be tested, so not only is it heavy, but it is not easy to replace the rotating body work, and there is also the problem of noise during work
[0011] In addition, since the rotating body provided in the test device has a structure similar to that of the yaw drive or the pitch drive, it is bulky and the space occupied by the test device in the work site is large. limit problem

Abstract

The present invention relates to a test device for a yaw drive and a pitch drive for a wind power generator, and in more detail, to a test device for a yaw drive and a pitch drive for a wind power generator. The rotary motion of the output part of the navigation drive or the pitch drive is converted into a linear motion rack, and is connected with a hydraulic cylinder that applies a load to the rack, so that the structure is simple, the noise is small, and it can be used in the work site Minimized space footprint Yaw drive Pitch drive.

Description

technical field [0001] The present invention relates to a testing device for a yaw drive and a pitch drive of a wind power generator, and in more detail, to a device provided with a device for converting the rotational motion of the output of the yaw drive or pitch drive to be subjected to a performance test into A rack that moves in a straight line, and a test device for a yaw drive and a pitch drive for a wind power generator that is connected to a hydraulic cylinder that applies a load to the rack, the test device has a simple structure, produces little noise, and can Minimizes space required on the job site Yaw drive Pitch drive. Background technique [0002] In general, a wind turbine is a device that converts wind energy into electrical energy, rotates the blades of the wind turbine, and generates power through the rotational force of the blades generated at this time. A wind turbine is a device that converts the energy carried by the wind into electrical energy. Tha...
