0引言油脂润滑是一种完全流失型润滑,以添加极压抗磨剂和稠化剂的矿物油作为润滑剂。为了防止润滑剂的过快流失,更为了使润滑剂可靠地吸附于摩擦副表面,形成润滑所需的油膜,油脂一般都具有较大的粘稠度。流动性差是润滑脂的主要形态特征。随着润滑脂在工作过程中的流失,或虽不流失,润滑脂在工作过程中受到污染也需要更新,隔一段时间需要在润滑点注入新的润滑脂,这是油脂润滑的另一个重要特征。由于油脂流动性差,润滑点分散,有的润滑点之间距离还很远,采用集中润滑具有一定难度,故传统的油脂加注方式是手工方式,即由操作者手持油枪,通过润滑点的油 0 Introduction Grease lubrication is a complete loss of lubrication to add extreme pressure antiwear agent and thickener mineral oil as a lubricant. In order to prevent excessive loss of lubricants, but also for the lubricant to be reliably adsorbed on the friction surface, the formation of oil film for lubrication, grease generally have a greater viscosity. Poor mobility is the main morphological characteristics of grease. As the grease is lost or lost during operation, the grease is also contaminated during operation and needs to be renewed. New grease needs to be injected at the lubrication points at intervals, which is another important feature of grease lubrication . Due to poor oil flow, lubrication points scattered, and some distance between the lubrication points is still far, the use of centralized lubrication has a certain degree of difficulty, so the traditional method of fat filling is manual, that is, by the operator hand gun, through the lubrication point oil
