Wind turbine gearbox is a large complex parts of wind turbine

the normal work of gears in gearbox can be affected by the intensity of gearbox directly.For the first domestic 2.5MW wind turbine

its three-dimensional model is finished.On the basis of mechanics theory of solid unit

ANSYS is the analysis platform

using appropriate restraint and loading to analysis the gearbox

also

the gearbox’s performance of intensity is assessed reasonably.By analyzing

test the feasibility of the design

find the weak link of design

and bring forward the key to the design of gearbox

also some improved measures.The results have been applied to engineering practice.
