摘要

目前工程车变速器存在振动大、使用寿命短等问题,而轮齿修形是改善变速器振动大和使用寿命短等问题的有效方法,并且,修形成本相比其他方法比较低。针对大功率液力变速器存在的问题,以Romax软件对变速器齿轮进行分析,根据现阶段齿轮修形研究的理论和实践经验,对齿轮修形参数进行寻优,通过多目标决策矩阵的方法,找到合理、综合评价系数高的优化值,对比优化前后的传递误差、齿面应力分布和温度值,得到相应的分析结果。结果表明,修形后减小了齿轮传递误差,齿面载荷分布均匀,接触温度最大值减小、分布更加合理,从而增强了齿轮传动的平稳性,增加了齿轮寿命。研究方法可更好地指导企业生产实践。

Abstract

At present,there are some problems such as large vibration and short service life,and the gear tooth modification is an effective way to improve the vibration and short life of the transmission,and the cost of repair is lower than other methods. Aiming at the problems of high power hydraulic transmission,the gears of the transmission are analyzed by using Romax software. Based on the theoretical and practical experience of the gear profile research at present,the gears are optimized and found to be reasonable and the comprehensive evaluation coefficient is high. By comparing the tooth surface stress distribution and the temperature value before and after the optimization and optimization results are obtained. The results show that the gear transmission error is reduced by the gear profile modification,which makes the tooth load distribution uniform,the maximum contact temperature is reduced and the distribution is more reasonable,which enhances the smoothness of the gear transmission,increases the gear life. The research method can be used for guiding the enterprise production practice.
