Study on the Dynamic Performance of Planetary Gear Transmission System of the MW Level Wind Power Speed-growth Gearbox by Wang Chunguang

“…The load sharing planetary gear speed-growth train for wind power generator is studied,which is composed of two stage planetary gear and one stage plane gear.The influence of external load excitation and time varying mesh stiffness is considered,and the system dynamics model including radial and torsion is deduced in detail.The dynamic mesh force between planet gear and sun gear and annular gear ring are analyzed.The radial velocity and torsional vibration angular velocity change on the central components of two stage planetary gear and the mesh force characteristics are obtained.This provides theoretical basis for the dynamic optimization design of the load sharing planetary gear speed-growth train.…”

Design and Research of the Performance of Torque Transmission of Locking Disc used to Wind Turbines by Jing Chaoyin

“…The locking disc is the connections between main shaft and input planet stage of wind turbines gearboxs.Because of the high cost of fault maintenance,the requirement of working reliability is more strict.Based on elastic plastic deformation theory of thick wall cylinder in the field of mechanics of materials,and combining the deformation compatibility condition,the calculation method of torque transmission of locking disc is researched,and some important factors which effects the performance of torque transmission are analyzed by combining with practical engineering.It provides theoretical basis for design,manufacturing and improving the working reliability of shrink disc.It is helpful to engineering application.…”
