“…The ring gear is fixed outside the side deck, and the power is transmitted from the sun gear to the planetary carrier. During the transmission process of the planet gear reducer, each rolling bearing generates heat because of the friction between the inner/outer ring and the rollers, and each meshing tooth generates heat because of the relative sliding between the meshing tooth surfaces [26,27] .…”

In order to study the influences of the initial liquid level on lube characteristics and oil-churning resistance moment of gear reducer, the heat generating power of one special kind of planet gear reducer under the special working condition is calculated. The fluid temperature at different initial liquid levels is calculated by FEA method. According to the relation between the physical parameters of the lube and the fluid temperature, the corresponding relation between the physical parameters of the lube and the initial liquid level is deduced. Based on the FEA results, the physical parameters of the lube are set to conduct the co-simulation of the oil-churning process of the planetary reducer under different initial liquid levels by MPS method. Depend on the simulation results, the influence of initial liquid level on lubricating flow state and oil-churning resistance moment of planetary reducer is analysed, and the initial liquid level is sifted. These studies provide methods and reference for lubrication medium set in transmission boxes, such as planet gear reducer and so on.

“…Mastrone et al [4] analyzed the internal oil distribution law under different rotational speeds for splash lubrication of spur gear pair, and concluded that the splash amount of lubricating oil increased with the increase of rotational speed. Lu et al [5][6] established the analysis model of splash lubrication of spiral bevel gear and single stage planetary gear system, and analyzed the convective heat transfer coefficient and temperature distribution of gear and bearing surface. Pang et al [7] studied the influence of different speed, torque and output power on the transient temperature field of sun gear and planetary gear through finite element method.…”

Based on RNG k-ε turbulence model and dynamic grid technology, the internal fluid dynamics model of splash lubrication three stage planetary gear reducer system is established. The distribution of lubricating oil and convective heat transfer characteristic in the system at different input rotational speeds are analyzed. The results show that at high speed condition, the oil gas mixing volume and the degree of atomization of lubricating oil are higher, and the convective heat transfer coefficient of tooth surface is larger, and it takes less time for the convective heat transfer coefficient to reach equilibrium. Meanwhile, the mean convective heat transfer coefficient on the tooth surface of sun gear, planetary gear and ring gear decreases successively.
