摘　　要：行星传动机构作为风电齿轮箱关键部件,因承受无规律的风力作用及强陈风冲击变载荷作用,所以行星轮系传动时的均载性水平对提高风电齿轮箱传动可靠性具有重要意义,行星轮组件轴向游隙是保证实现行星轮系中太阳轮浮动的前提,是提高行星轮系传动均载性水平、使用寿命的关键。针对行星轮组件轴向游隙偏大问题,分别从测量方式、测量仪表、装配工艺、轴承内外圈高度差4个方面对行星轮组件轴向游隙的影响进行了深入分析,确认了轴承内外圈高度差对行星轮组件轴向游隙的影响,通过引入轴承内外圈高度差因素,解决了行星轮组件轴向游隙偏大问题。Planetary transmission mechanism as the key components of wind power gear box,because under irregular and impact variable loads, so the load level of the planetary gear transmission is great significance to improve the transmission reliability of wind power gear box, the axial clearance of the planetary gear assembly is the premise to ensure implementation of the floating sun gear in planetary gear train, is the key to improve the load level, the planetary gear transmission service life.Aiming at the problem of planetary wheel bearing axial clearance is too large,respectively, deeply Analysis fiom four aspects, measurement method, measuring instrument,the assembly process, the height difference of bearing inner and outer ring, confirmed the height difference of bearing inner and outer ring that effect on the axial clearance of planetary gear assembly, by introducing the factor of the bearing inner and outer ring height difference, identify the problem and solved the problem.
