Hydrodynamics, elastohydrodynamics and squeezing film lubrication analysis on lubrication model of gear transmission with belt as meshing medium indicate the belt make lubricant film easy to come into being even water used as lubricant.

• 在建立带式啮合介质齿轮传动的润滑模型的基础上,通过对润滑模型的流体动力学润滑、弹性流体动力学润滑和挤压膜润滑进行分析发现,由于介质带的存在,润滑膜很容易形成,甚至可以形成具有相当承载能力的润滑水膜。
