Abstract: Gear simulated failure test platform can be representative of the equipment failure being easy for research personnel to carry on diagnosis study and the validation process. Also it provides accordance for the diagnoses of failure gear. At the same time, it helps scientific research personnel in the experiment of time and energy. The experimental stage also can be used in teaching practice and improve the level of cognition. Therefore, it is very necessary to design a gear simulated failure test platform.
By learning the process of structural design of an emulator which is one part of gear simulated failure test platform, I have designed a simulation of six kinds of representative of the experiment in this article. Operators can observe consecutively the signal of the gear from normal to the wrong and the synthesis signal of the two meshing gear. This pleted the general scheme analysis and design calculations of the simulator, designed the sizes of the gear box, the structure of the geometry of the parameters and precision level and calculated the structure parameters of the enter shaft, the output axis and the intermediate shaft. Then, I check the strength and carry on the precisely core size. At last, I estimated the working life of all the bearings checked the strength of all keys.
