在精密齿轮传动装置中,传动位置误差和回差是评定装置精度的两项重要指标。齿轮传动位置误差和回差的大小主要取决于齿轮误差和装置误差,在齿轮误差的研究中,对于应用于精密传动装置中的齿轮,人们更感兴趣的是齿轮输出功能,即齿轮固有位置误差和侧隙。本文阐述了齿轮固有位置误差这一概念,分析了影响齿轮固有位置误差的主要因素,齿轮单项误差,综合误差与固有位置误差的关系,以及齿轮固有位置误差的统计计算方法,从而方便了齿轮传动装置的设计计算和精度分析。
In precision gear drives, drive position error and backlash are two important criteria for evaluating device accuracy. Gear transmission position error and backlash depends on the size of the gear error and device error in the study of gear error, precision gear used in the gear, people are more interested in the gear output function, that is, the inherent gear error And backlash. This paper describes the concept of gear inherent position error, analyzes the main factors that affect the inherent position error of the gear, the single error of the gear, the relationship between the integrated error and the inherent position error and the statistical calculation method of the inherent position error of the gear, which facilitates the gear transmission Device design calculation and precision analysis.
