1.使用场合影响 开式传动如各类联合收割机、割晒机等链条 应采用油脂润滑。 闭式传动如手扶拖拉机链条传动箱，应采用 机油润滑。 2.温度影响 一般推荐在-5℃~+60℃范围内使用润滑。 冬季采用粘度小的机油，夏季采用粘度大的 机油。 3.线速度影响 润滑方式直接与链条线速度有关，可参照下 图选择润滑方式。 链条线速度（米／秒）Chain speed(m/s) 15 12.5 10 8 6 5 4 2.5 2 1.75 1.5 1.25 1 0.8 0.6 0.5 0.4 0.3 0.25 8 9.525 12.7 15.87519.05 25.4 31.7544.45 50.8 63.5 76.2 1. 强制润滑 Forced lubrication 2. 油环润滑 Lubrication by slinger disk 4. 人工润滑或滴油润滑 Manual or dripping lubrication 3. 油池润滑 Oil bath lubrication ■ Lubrication of chain depends on the working environment, temperature, chain speed and so on. 1. Influence of working environment For open drive such as combine chain, swather chain etc., grease lubrication is recommended. For closed drive such as walking tractor chain transmission case etc., oil lubrication is recommended. 2. Influence of temperature Application in the temperature range of -5 ℃ to +60 ℃ is recommended. In winter, lower viscosity oil is recommended; But in summer, higher viscosity oil is recommended. 3. Influence of chain speed The lubrication method is related to chain speed. Refer to the following chart for details, please. ■ 链条传动的润滑取决于使用场合、 温度、链条线速度等。 润滑选择 Selection of lubrication www.dhchain.com 576 东华链条集团 DONGHUA CHAIN GROUP
