0引言水泥厂的大型设备如回转窑、磨机等普遍采用开式齿轮传动,其工况条件是低速、重载、高温。这就要求润滑剂必须具备下列性能:能够在啮合齿面间形成足够厚度的油膜;能够承受较高的齿轮运行温度;能够降低摩擦系数;能够有效吸收齿轮啮合时的冲击力,降低齿轮承受的冲击载荷;能够有效降低齿轮的 0 Introduction Large cement plants such as rotary kilns, mills and other commonly used open gear drive, the working conditions are low speed, heavy load, high temperature. This requires the lubricant must have the following properties: to be able to form a sufficient thickness between the meshing gear oil film; can withstand higher gear operating temperature; can reduce the friction coefficient; can effectively absorb the gear meshing impact, reducing the gear to withstand Impact load; can effectively reduce the gear
