机床设备采用定时定量集中自动润滑技术,已成为机床设备润滑技术的发展方向。本文介绍节流式和容积式集中润滑系统的设计程序以及摩擦副耗油量方面的技术问题。 (一)摩擦副耗油量的确定 1.计算摩擦副耗油量的经验公式摩擦副在单位时间(小时)的耗油量与接触面积、运动速度、表面压强、摩擦副所在部位以及它的开动率等因素有关。在这里推荐采用日本“正和油机贩壳株式会社”于70年代通过试验总结出的一套经验公式。如表1:
Machine tools using quantitative automatic fixed-time lubrication technology, machine tool lubrication technology has become the direction of development. This paper introduces the design procedure of throttling and volumetric centralized lubrication system and the technical problems of friction pair fuel consumption. (A) Determination of the friction fuel consumption 1.Experience formula to calculate friction pair fuel consumptionFriction pairs in fuel consumption per unit time (hours) and the contact area, velocity, surface pressure, where the friction pair and its Starting rate and other factors. Recommended here in Japan, “And Oil Trailer Co., Ltd.” in the 70s through the experiment summed up a set of empirical formula. As shown in Table 1:
