使用NSK轴承,润滑脂是非常关键的。使用变质的润滑脂,不仅起不到应有的作用,而去还会损坏轴承。

Use the NSK bearings, grease is critical. Use metamorphic grease, not only to play their rightful role, and also damage the bearing.

1、油流观察法

取两只量杯,其中一个盛有待检查的润滑油,另一只空放在桌面上,将盛满润滑油的量杯举高离开桌面30-40厘米并倾斜,让润滑油慢慢流到空杯中,观察其流动情况,质量好的润滑油油流时应该是细长、均匀、连绵不断,若出现油流忽快忽慢,时而有大块流下,则说润滑油已变质。

1, oil flow observation method

Take two only measuring cup, which a Sheng to be check of lubricants, another a only empty placed in desktop Shang, will Sheng full lubricants of measuring cup cite high left desktop 30-40 cm and tilt, let lubricants slowly stream to empty Cup in the, observation its flows situation, quality good of lubricants oil stream Shi should is slender, and uniform, and continuous, if appears oil stream suddenly fast suddenly slow, sometimes has large shed, is said lubricants has metamorphic.

2、 手捻法

将润滑油捻在大拇指与食指之间反复研磨,较好的润滑油手感到有润滑性、磨屑少、无摩擦,若感到手指之间的砂粒之类较大摩擦感,则表明润滑油内杂质多,应更换新润滑油。

2, hand-twisted method

Would lubricants twist in the repeated grinding between thumb and forefinger, better Lube hand felt the lubricity, less debris, without friction, who feel that sense of larger sand grains such as friction between the fingers, then lubricating oil impurities within, new lubricant should be replaced.

3、 光照法

在天气晴朗的日子,用螺丝刀将润滑油撩起,与水平面成45度角。对照阳光,观察油滴情况,在光照下,可清晰地看到润滑油中无磨屑为良好,可继续用,若磨屑过多,应更换润滑油。

3, lighting method

On sunny days, with a screwdriver would lubricants stir, with the horizontal plane to a 45-degree angle. Against the Sun, observing oil droplets, in sunlight, you can clearly see no debris in lubricating oil for good may continue to be used, if excessive debris, should be replaced with oil.

4、油滴痕迹法

取一张干净的白色滤纸,滴油数滴在滤纸上,待润滑油渗漏后,若表面有黑色粉末,用手触摸有阻涩感,则说明润滑油里面杂质已很多,好的润滑油无粉末,用手摸上去干而光滑,且呈黄色痕迹。

4, oil droplets traces law

Take a clean white filter paper, drip a few drops on the paper, after the oil leakage, if surface has black powder, tart touch resistance, then Lube there are many impurities, a good lubricant powder-free, dry and smooth to touch, and traces of yellow.
