Assessment for the quality of rolling bearing parts based on fuzzy theory
Scientific Research and Essays(2014)
Abstract
There are many factors leading to rolling bearing failure, and the issue of parts quality like roller error and inner ring error is one of the main influence factors causing premature failure of the bearing.Assessment for bearing parts quality can obviously eliminate or minimize the chance of potential failure, and can improve the service life of bearing, wear-resisting property and reliability.For the sake of the assessment for the rolling bearing parts quality, a new fuzzy comprehensive evaluation method of parts quality was brought forward to account for it.Based on fuzzy theory and mathematical statistics, bearing parts quality evaluation model was established.Fuzzy comprehensive evaluation can objectively and truly reflect the quality of the bearing parts.That we synthetically evaluate the parts quality by the aid of the fuzzy comprehensive evaluation model has great value in theory and practice, and lays a new foundation for the quality evaluation of bearing parts.Then, with the condition of poor information, we take type 30204 tapered roller bearing roller quality evaluation for example to illustrate the application of the model, and the results show that using this model to assess the quality of parts is feasible.
