| Abstract: | A technology of tooth root stress measurement is proposed in this paper for the modification evaluation during the design of wind turbine gearbox.The load distribution factor in the direction of tooth and mesh load factor can be measured at the same time by this technology.This paper introduces the principle of gearbox stress measurement system and its main components.Furthermore,the typical stress distribution and mesh load factor results are given,and programmed amplifier and I2C bus communication in the test system are described in detail.The test practices show that meshing state of gears can be analyzed quantitatively by this system and the analysis results are of importance in the reference value for the gear modification and structure design. |
