Transmission of CSF-20-100-2UH motion for Harmonics reducer of Hamenaco Pith module. Harmonic drive is usually composed of three basic components, including a rigid wheel with inner teeth, a flexible wheel with outer teeth that can produce radial elastic deformation when working, and a wave generator installed in the flexible wheel internal transmission part wave, oval shape, with flexible rolling bearings in the outer ring. The number of external teeth of flexible wheel is less than the number of internal teeth of rigid wheel. When the wave generator rotates, the outer teeth of the flexible wheel corresponding to the long axis direction just completely engage the inner teeth of the rigid wheel
Because of the complexity of gear parts, there are many random factors affecting the fatigue life of gear, so it is a very complicated work. It involves the selection of appropriate sampling method, sample size of CSF-20-100-2UH for the Harmonics reducer of the Hamanaker head module, loading method, test accuracy, distribution hypothesis and goodness-of-fit testing, and subsequent iterations.
The other is that if the weakest point of a part is supported by stronger points around it {an averaging process is produced, the result will be a normal distribution. Of course, in addition to material, gear structure and loading mode, also have an important impact on life or strength distribution. Based on this analysis, it is generally considered that the contact fatigue strength of the gear of the HARMONics reducer CSF-20-100-2UH of hamenako head mode follows roughly the Log normal distribution or Weibull distribution, while the bending fatigue strength follows roughly the log normal distribution or lognormal distribution.
In order to solve the number of specimens, the test time and test precision of contradiction, has put forward some theory and methods of the accelerated life tests, such as the constant stress accelerated life test based on the theory of the cumulative damage hammer naco yuntai module harmonic reducer CSF - 20-100-2 uh, step or sequence into stress accelerated life test, and some quick test method, etc. Since the accelerated life test is to infer the test results under normal conditions from the results of the reinforcement test,
You have to look at the average of the population. The so-called average: test refers to the test of two population mean sum according to two samples. If the population mean is the same, then it can be considered that the two sub-samples are from the population with the same mean. · The difference between the two groups of test results is due to chance factors. On the contrary, it is considered that there are systematic differences.
