Abstract：To investigate the cage stability of high-speed oil-lubricated angular contact ball bearings, a dynamic model of cages is developed on the basis of Gupta's and Meeks' work. The model can simulate the cage motion under oil lubrication with all six degrees of freedom. Particularly, the model introduces oil-film damping and hysteresis damping, and deals with the collision contact as imperfect elastic contact. In addition, the effects of inner ring rotational speed, the ratio of pocket clearance to guiding clearance and applied load on the cage stability are investigated by simulating the cage motion with the model. The results can provide a theoretical basis for the design of ball bearing parameters.In high-speed applications such as jet-engines and gyros, the instability of rolling bearing elements might lead to the sudden and catastrophic failure long before the anticipated fatigue life. This leads to the computational modeling and simulation of bearing dynamics to predict the conditions under which such instable motion might occur. Cage stability is one of the most important factors affecting the performance and life of rolling bearings. Thus the investigation of cage instability has received broad attention.Ball rolling bearings are the primary choice of high speed. Many researchers have developed some dynamic models, and investigated the influencing factors on cage stability. Walter [1] initially developed an analytical model for ball bearing. Gupta [2,3] developed a bearing simulation model ADORE, which is capable of simulating the motion of each bearing element in all six degrees of freedom. By simulating, Gupta investigated the correlation between cage instability and frictional characteristics of lubricant besides the effects of cage clearance, dynamic load and cage unbalance on the cage instability of a solidlubricated ball bearing. Meeks et al [4,5] proposed a dynamic model for the ball bearing in which there are six degrees of freedom for a cage. Kannel, Boesiger, Kingsbury Tateishi and other researchers made a great deal of studies on the dynamics of the cage of ball bearings. In additional, several researchers studied the dynamic characteristics of the cage of cylindrical or tapered roller rolling bearings [6,7] .The cage and balls with six degrees of freedom are considered in Gupta's dynamic model, but oil-film damping and hysteresis damping are not considered, and the contact is assumed as the perfect elastic contact. Although the contact is considered as the non-perfect contact in Meeks' model, but the motion of ball is constrained. Moreover, Meeks' model applies to the solidlubricated ball bearing.In China, the studies of the simulation of rolling bearings are mostly focused on cylindrical roller rolling bearings [8][9][10][11][12] , and some marked achievements have been made. By contrast, the studies of angular contact ball bearings are fewer, and the quasi-dynamic model rather than three-dimensional dynamic model is used to analyze the angular contact ball bearings [13,14] .

“…For the modeling of the assembly interactions, assuming that there is an excess of the grease in the cage-roller assembly, a critical value Δh 0 of the grease lm thickness is assumed for the contact state transition. When δ ≥ Δh 0 , there are only the hydrodynamic e ect between the kth slice and pocket crossbeam, and no Hertzian contact [9,21]. e minimum grease lm thickness h 0 δ. e hydrodynamic pressure q c and the grease lm traction force f c between the kth slice and crossbeam are…”

“…Deng [8] analyzed the dynamics of the TRB with oil lubrication by using the Adams-Bashforth-Moulton multistep method and studied the cage whirling and roller skew of the bearing. By considering six degrees of the cage motion, Sakaguchi and Harada [9,10] simulated motions of the rigid or exible cage in TRBs on the dynamic simulation software ADAMS.

Tapered roller bearings (TRBs) are applied extensively in the field of high-speed trains, machine tools, automobiles, etc. The motion prediction of main components of TRBs under grease lubrication will be beneficial to the design of bearings and the selection of lubricating grease. In this study, considering the dynamic contact relationship among the cage, rollers, and raceways, a multibody contact dynamic model of the TRB was established based on the geometric interaction models and grease lubrication theories. The impacts of load, grease rheological properties, and temperature on the roller tilt and skew and the bearing slip were simulated by using the fourth-order Runge–Kutta method. The results show that the roller tilt angle in the unloaded zone is obviously larger than that in the loaded zone, while the roller skew angle in the unloaded zone is smaller than that in the loaded zone. As the speed increases, the roller tilt and skew and the bearing slip become more serious. Bearing preload can effectively reduce the bearing slip but will make the roller tilt and skew angle increase. The roller skew angle and the bearing slip decrease with the increase of the grease plastic viscosity. The roller tilt angle increases with the increase of the plastic viscosity. The yield stress of the grease has little effect on motions of the roller and cage. The influence of temperature on the roller and cage motions varies with the type of grease used.
