October 30, 2007 Maintenance Free Solutions for the Metals Industry冶金行业免维护解决方案 Presented at Customer Days Presented by Jimmy Nielsen, SKF Exopar Sweden 2010-10-27 Presentation content Dry Lubrication 干式润滑 Dry lubricant干式润滑 Dry lubricants are materials in solid phase able to; 干式润滑剂是一种表现为固态的材料，其能够 Reduce friction between surfaces 减少接触面间的摩擦 Prevents steel-steel contact 避免钢对钢的接触 Distribute contact load 合理分配接触应力 Examples of dry lubrication materials 干式润滑剂材料 Graphite 石墨 Molybdenum disulfide 二硫化钼 Tungsten disulfide 二硫化钨 Extreme temperature problems in Metals Industry冶金行业中的极限工作温度问题 Difficult to find suitable lubrication for high to extreme temperatures approx. (+150 to +350 °C) 很难找到一种合适的润滑剂能适用于高至极高温工况 Frequent relubrication required when oil or grease is used 在油、脂润滑条件下，需进行频繁的二次润滑 Difficult to seal high temperature application = contamination 高温条件下密封会变得很困难—污染物 Toxicity at high temperature 高温条件下的有毒氛围 High friction and energy losses 高摩擦所带来的能量损失 Fire hazard from grease leakage 油脂泄漏所带来的火灾隐患 Workers safety 操作工人的安全性 Effects of high temperatures on the bearing高温对轴承的影响 Use the right lubricant使用正确的润滑剂 SKF DryLube Bearings – a new generation dry lubricated bearingsSKF干式润滑轴承—新一代干式润滑轴承 What is SKF DryLube?什么是SKF 干式润滑？ Lubricating paste injected into the bearing and hardened around existing metal cage 润滑剂被注入轴承内部，并围绕已有金属保持架硬化 Lubricating media = Graphite, MoS2 and special additives 润滑介质= 石墨， MoS2 以及其它特殊添加剂 For applications from -60 up to 250degrees C, peaks up to 350 degrees C 适用温度从-60到250℃，峰值达到350℃。 Can be applied to most bearing types (not NRB and CARB due to lack of free space). 适用于绝大多数轴承类型（但不包括内部空间太小的滚针和CARB轴承） Is available in four versions 4种可用版本 VA210 – graphite based 石墨 VA2101 – graphite + additive 石墨+添加剂 VA2103 – MoS2 based 二硫化钼 VA237 – graphite + special additive 石墨+特殊添加剂 DryLube features benefits干式润滑的优点 Extreme temperature range from -60°C to +250°C, with peak temperatures up
