发动机试验台架联接装置的设计及改进

Engine Test Bench Connection Device Design Improvement

发动机进行台架可靠性试验时,发动机与测功机的旋转联接部件是动力输出关键部件,文章中对发动机动力输出方式及输出轴装置的设计,有效地解决了在发动机高速高负荷运转时,发动机、测功机震动大,联接轴易断裂变形,工装一轴轴承超温等问题。

When the engine bench test, connection part is very important for engine and bench, we design engine power output mode and connection shaft device in this article, it effectively solve big bench shake, avoid connection shaft breakdown and bearing temperature exceeds the limit value when engine work on high speed and high load
