| Abstract: | For the purpose of improving load capacity,the two-stage with two-teeth difference pin cycloid planetary gearing drive is proposed to replace the three-stage involute planet gear drive which used in 1.5 MW wind turbine.Structure and work principle of this new type reducer are described in detail.After that,to be considered,the main factors are pin cycloid gear meshing efficiency,bearing efficiency and output mechanism efficiency.Finally,the transmission efficiency of this new-type reducer is calculated by the inverted mechanism method. |
