【摘要】 为减小行星传动系统回差,提高其传动精度,在NGW行星齿轮传动系统的基础上,提出一种行星轮并联均布齿轮传动系统。综合考虑齿轮偏心误差和工作载荷对行星传动系统回差的影响,得到传动系统的回差数学公式,分析了载荷及齿轮偏心误差对传动系统回差的影响。研究结果表明,随着工作载荷增大,行星轮并联均布齿轮传动系统与NGW行星齿轮传动系统的回差均增大,且较为接近,但NGW行星齿轮传动系统回差增幅略大;相同齿轮偏心误差条件下,行星轮并联均布齿轮传动系统回差小于NGW行星齿轮传动系统回差;行星轮并联均布齿轮传动系统中,太阳轮偏心误差对于传动系统回差影响较大,外齿圈偏心误差影响较小,行星轮偏心误差的影响介于二者之间。更多还原

【Abstract】 Based on the NGW planetary gear transmission system,a gear transmission of parallel uniform planetary gear is proposed to reduce the transmission error of asteroid transmission system and improve its transmission accuracy. The backlash formula is obtained by considering the influence of gear eccentricity error and working load on the backlash of planetary transmission system. The influence of load and gear eccentricity error on the transmission system is analyzed. The results show that,as the working load increasing,the backlash of gear transmission of parallel Uniform Planetary gear and NGW planetary gear transmission system are all increased. But the backlash of NGW planetary gear transmission system is slightly larger. Under the condition of same gear eccentricity error,the backlash of gear transmission of parallel uniform planetary gear is less than the backlash of NGW planetary gear transmission system. In the gear transmission of parallel uniform planetary gear,the eccentricity error of the solar wheel has a great impact on the transmission system,but the eccentricity error of the outer ring has less influence on the transmission system. The influence of planetary wheel eccentricity error on the transmission system is between sun wheel and planet gear.更多还原
