本文说明了对小模数齿轮的单齿进行不同能量的多次冲击的试验方法,得出了冲击能量与破断次数曲线,分析了影响试验结果的一些因素。并指出了注意事项。一、试验方法试验是在我校制造的DC-150型多次冲击试验机上进行的。试验机原来只能作常规试棒试验,为了作单齿重复冲击试验,对机器进行了改装,设计制造了一套专用夹具和几个冲击刀口。改装时,用一块垫铁取代原来冲击弯曲用的砧铁。以垫铁为基准面,将一个u形卡槽固
In this paper, the test method of multiple impact with different energy of single tooth of small modulus gear is described. The curve of impact energy and breaking number is obtained. Some factors affecting the test result are analyzed. And pointed out the precautions. First, the test method Test is made in our school DC-150 multiple impact test machine carried out. The original test machine can only be used as conventional test rod test, in order to make a single tooth repetitive impact test, the machine was modified, designed and manufactured a set of special fixture and a few impact knife. When the conversion, with a piece of horn to replace the original impact bending with anvil iron. To horn as a reference plane, a u-shaped card slot solid
