齿轮弯曲疲劳强度是考核齿轮质量的一项重要性能指标。目前,国内齿轮弯曲疲劳强度试验,使用一些专门设计的试验装置,其中包括一套专门加载系统、激振系统及测力系统,结构复杂,不能一机多用。而目前我国生产的一些可施加脉动载荷的万能试验机又无齿轮弯曲疲劳试验夹具。为此,我们研制了一种单齿弯曲疲劳强度试验装夹装 Gear bending fatigue strength is an important indicator of gear quality assessment. At present, the domestic gear bending fatigue strength test, the use of some specially designed test equipment, including a set of specialized loading system, excitation system and force measurement system, the structure is complex and can not be a multi-purpose machine. At present, some of our production of universal testing machine can exert pulsating load without gear bending fatigue test fixture. To this end, we have developed a single tooth bending fatigue strength test fixture
