【摘要】:基于測試方法,針對工程實際問題,對某型發(fā)動機含直齒錐齒輪副和零度弧齒錐齒輪副的二級圓柱齒輪-錐齒輪高速傳動系統(tǒng)進行動態(tài)傳動誤差測量,并對測得的動態(tài)傳動誤差數(shù)據(jù)進行濾波、頻譜分析,得到高速錐齒輪動態(tài)性能參數(shù)。分析表明:采用零度弧齒錐齒輪時,其低頻段動態(tài)傳遞誤差比采用直齒錐齒輪時降低很多;采用零度弧齒錐齒輪時,其高頻段動態(tài)傳動誤差幅值要遠大于采用直齒輪時的幅值,而高頻段的幅值決定了傳動系統(tǒng)動態(tài)特性優(yōu)劣,進而說明采用零度弧齒錐齒輪時,系統(tǒng)的動態(tài)性能將劣于直齒錐齒輪。
[Abstract]:Based on the test method and aiming at the practical engineering problems, the dynamic transmission error of the secondary cylindrical gear bevel gear high speed transmission system with straight bevel gear pair and zero degree spiral bevel gear pair in a certain engine is measured. The measured dynamic transmission error data are filtered and the spectrum analysis is carried out to obtain the dynamic performance parameters of high speed bevel gear. The analysis shows that the dynamic transmission error in low frequency band is much lower than that in straight bevel gear when zero degree spiral bevel gear is used. When zero degree spiral bevel gear is used, the amplitude of dynamic transmission error in high frequency section is much larger than that when straight gear is adopted, and the amplitude of high frequency section determines the dynamic characteristics of transmission system, which shows that when zero degree spiral bevel gear is adopted, The dynamic performance of the system will be inferior to that of spur bevel gear.
