【Abstract】 The gear system is widely used in many industries such as aerospace, wind power and automobile manufacturing,and its dynamic performance is affected by various nonlinear factors, such as meshing stiffness and tooth side clearance; a series of problems often take place, for example, low accuracy in gear transmission, poor system stability, and so on. This article focuses on the influence of the tooth side clearance on the gear system’s dynamic performance; efforts are made to straighten out the research on the influence of the tooth side clearance on the gear system from the following aspects: classification of the gear system’s model, types of the solving methods, improvement of the tooth side clearance’s model, judgement of the system stability,analysis on the dynamic response, research on the nonlinear characteristics, performance evaluation and reliability prediction, and so on. Besides, it is concluded that more research should be done, such as coupling of various nonlinear factors, optimization of the solving methods, modelling of the complex systems with the tooth surface’s micromorphology, changes of the dynamic characteristics influenced by multiple factors, reliability prediction with uncertainties, and so on.更多还原
