    Abstract
  • The research progress of the frictional properties of the spherical plain bearing was sorted out from two aspects of the external factor and surface treatment. The research progress of the residual life prediction of the spherical plain bearing was reviewed in terms of model prediction and data-model fusion prediction. The effects of the load, environmental temperature, swing cycle, lubricating materials, surface coating, surface modification, surface texture, and surface processing on the frictional properties of the spherical plain bearing were analyzed. The influencing factors and prediction methods of the spherical plain bearing life were discussed. Research results show that external factors have a significant influence on the friction and wear of the spherical plain bearing. In most cases, multiple factors are usually coupled during operation. Therefore, it is necessary to elucidate the mechanisms of the external factors on the friction and wear of spherical plain bearing, then the structure, lubrication mode and wear-resistant material of the joint bearing can be designed. Surface treatment can reduce the wear of spherical plain bearing friction pairs, and to improve the friction and wear of spherical plain bearing friction pairs by surface treatment, it is necessary to clarify the influence rules of coating parameters, modification process, texture parameters, and processing technology on the frictional properties of spherical plain bearing, so as to develop a surface treatment method with characteristics such as low cost, high reliability, low energy consumption, and minimal environmental pollution and enhance the frictional properties of the spherical plain bearing. There are many internal and external factors that affect the residual life of the spherical plain bearing. To accurately predict the residual life of the spherical plain bearing, it is necessary to analyze the operating conditions and friction and wear of the spherical plain bearing under service conditions. As a result, a reliable life prediction model and evaluation method can be established to predict the residual life of the spherical plain bearing.
