详尽分析了低速重载齿轮减速器中的大型径向滑动轴承的设计。要确保这类轴承的运行寿命,在设计时应着眼于两个重要目标,即在最严重的工作条件下保证油膜润滑的最小油膜厚度和控制承载油膜的最高温度。此外,设计成套低速重载齿轮减速器的轴承,应考虑油膜压力分布的完整性、安装及其对轴承强度、刚度、负荷,效率、寿命等的要求。提出了在边界润滑状态下,要确保轴承正常工作的解决办法。
The design of large-scale radial plain bearing in low-speed heavy-duty gear reducer is analyzed in detail. To ensure the operational life of such bearings, two important goals should be considered when designing, that is, the minimum oil film thickness to ensure oil film lubrication and the maximum temperature to control the oil film under the most severe working conditions. In addition, the design of a complete set of low-speed heavy-duty gear reducer bearings, oil film pressure distribution should be considered the integrity of the installation and its bearing strength, stiffness, load, efficiency, life expectancy and other requirements. Proposed in the state of boundary lubrication, to ensure the normal operation of the bearing solution.
