Experimental Study on Load Sharing Characteristics of Fixed Axis Tri-Branching Gear Transmission System
摘要
Abstract
The current load sharing characteristic test of gear transmission systems does not consider the influence of processing and installation errors such as backlash and shaft eccentricity angle on load sharing characteristics.To address this issue,a load sharing characteristic test bench for a gear transmission system was built for a fixed axis power tri-branching gear transmission system.The backlash was accurately adjusted by adding a thin gasket at the bearing seat,and the shaft eccentricity angle was adjusted by designing the eccentric sleeve structure.The tooth root stress of the center gears of the split and combiner stages was tested under different operating conditions to explore the influence laws of the load sharing characteristics.Temperature compensation strain gauges were adopted to eliminate the influence of temperature interference on the test accuracy.The correlation between load,backlash,and shaft eccentricity angle and the load sharing characteristic was analyzed in detail.The results indicate that the load sharing characteristics of the combiner stage are superior to those of the split stage.The load sharing effect of the two-stage gears improves as the load increases;the shaft eccentricity angle has a significant impact on the load sharing characteristics of the gears.关键词
