摘要

对渐开线非对称齿轮的齿形进行了设计,建立了齿条刀、齿坯和机架的协同坐标系,对齿条刀进行了端面设计,确定了齿形轮廓方程,并对齿形轮廓进行了模拟仿真。对加工出的渐开线非对称主动小齿轮的单齿接触点进行了受力分析,利用公式法对20°/20°、25°/20°、30°/20°和35°/20°四种压力角组合的受力进行了数值计算,并用有限元法进行了验证,对比分析结果表明,工作齿面采用大压力角可以有效地提高齿轮的接触强度与弯曲强度。

Abstract

The asymmetric involute gear tooth is designed,a collaborative coordinate of rack cutter,gear blanks and frame is built,the end face of rack cutter is designed,the tooth profile equation is determined,the tooth profile is simulated.The stress of single contact point to active small gear is analyzed,four force pressure angle combination are calculated using the formula method on 20° /20°,25° /20°,30° /20° and 35° /20°,the result is verified by using the finite element method,the comparative analysis results show that work with large pressure angle tooth surface can effectively improve the contact strength and bending strength of the gear.
