机床中镇江SKF轴承6000的维护***的直接方式

主轴是数控机床的重要组成部分，主要由主轴、镇江SKF轴承、主轴停止装置、自动夹紧和切屑去除装置等组成。数控机床主轴零件的润滑、冷凝和密封是机床使用与维护中的重要问题。

Spindle is an important part of CNC machine tools, mainly composed of spindle, Zhenjiang SKF bearing, spindle stop device, automatic clamping and chip removal device. The lubrication, condensation and seal of spindle parts of CNC machine tools are important problems in the use and maintenance of machine tools.

首先，主轴部件的降温主要是为了减少轴承发热并实际地控制热源。

First of all, the cooling of the spindle components is mainly aimed at reducing the bearing heating and controlling the heat source practically.

其次，主轴部件的密封不仅要防止灰尘进入主轴部件的切屑和切削液，还要防止润滑油的泄漏。

Secondly, the sealing of the spindle components should not only prevent dust from entering the chips and cutting fluid of the spindle components, but also prevent the leakage of lubricating oil.

主轴部件的镇江SKF轴承密封有两种形式：接触式和非接触式。在接触毛毡环和耐油橡胶环时，应注意检查其老化和损坏；非接触密封防止泄漏，这对于保证返回油能尽***出，确保回流孔顺畅非常重要。

There are two forms of Zhenjiang SKF bearing seal for spindle components: contact type and non contact type. In contact with felt rings and oil-resistant rubber rings, attention should be paid to check their aging and damage; non-contact sealing to prevent leakage, which is to ensure that the return oil can be discharged as soon as possible, to ensure that the return hole ***oothly.

首先，良好的润滑效果，可以降低轴承的工作温度，延长使用寿命；因此，在操作和使用中应注意：低速、油、循环油润滑；高速油雾、油气润滑。

First of all, good lubrication effect, can reduce the working temperature of bearings, prolong service life; therefore, in operation and use should pay attention to: low-speed, oil, circulating oil lubrication; high-speed oil mist, oil-gas lubrication.

但是，当使用润滑脂时，主轴轴承润滑脂的注入量通常为10~15个百分点的轴承空间，不要填充，因为镇江SKF轴承润滑脂过多，会加剧主轴的加热。油雾润滑时，须每天检查主轴温度控制箱的润滑剂是否足够T，如果油量不足，应及时补给；同时，注意检查润滑剂的温度范围是否适当。

However, when using grease, spindle bearing grease injection volume is usually 10-15 percentage points of bearing space, do not fill, because Zhenjiang SKF bearing grease too much, will intensify the heating of the spindle. When lubricating with oil mist, it is necessary to check whether the lubricant in the spindle temperature control box is sufficient T every day, and if the oil is insufficient, it should be replenished in time; at the same time, it is necessary to check whether the temperature range of the lubricant is appropriate.

油气润滑和油雾润滑的常用润滑方法是油雾和润滑油雾的连续供给。油气润滑是将油雾送入轴承间隙的定时、定量，不仅实现油雾润滑，而且避免油雾对周围空气的过度污染。喷雾润滑是利用大流量恒温油（3～4L/min每轴承）进入主轴轴承，实现润滑和冷凝。较大的注入体积须由油泵强制而不是自然回流。同时，恒温油箱容量大，控制油温在+0.5摄氏度变化精度高。

The common lubrication method of oil air lubrication and oil mist lubrication is continuous supply of oil mist and lubricating oil mist. Oil-air lubrication is to feed oil mist into the bearing clearance of the timing and quantitative, not only to achieve oil mist lubrication, but also to ***oid excessive pollution of the surrounding air. Spray lubrication is to achieve lubrication and condensation by using large flow c***tant temperature oil (3 ~ 4L/min per bearing) into spindle bearings. The larger injection volume must be forced by the oil pump rather than the natural reflux. At the same time, the temperature of the c***tant temperature tank is large, and the oil temperature is controlled at +0.5 degrees Celsius.

为了保证主轴具有良好的润滑性，减少摩擦热，并能带走主轴组件的热量，通常采用循环润滑系统，强大的油润滑液压泵，油温升降器来控制水箱的温度。

In order to ensure that the spindle has good lubricity, reduce friction heat, and can take away the heat of the spindle assembly, usually the use of circulating lubrication system, powerful oil-lubricated hydraulic pump, oil temperature riser to control the temperature of the water tank.

高质量数控机床主轴轴承采用质量相对较好的镇江SKF轴承润滑脂密封和橡胶密封润滑。油脂可使用7～10年。新的润滑降温方法不仅降低了轴承温升，而且减少了轴承内外圈之间的温差，保证了主轴的小热变形。

The spindle bearings of high quality CNC machine tools are lubricated by Zhenjiang SKF bearing grease seal and rubber seal. Oils and fats can be used for 7~10 years. The new lubrication cooling method not only reduces the temperature rise of the bearing, but also reduces the temperature difference between the inner and outer rings of the bearing and ensures the ***all thermal deformation of the spindle.
