电机上镇江NSK轴承系列清洗与压装方式

用软干油或防锈油膏硬化的轴承应长期浸泡在100-200摄氏度的油中。轴承被夹紧，轴承上的油脂用刷子清洗。软干性油或防锈软膏在加热到100-200摄氏度时会融化。从轴承裂缝中洗去是很容易的。有时，只要镇江NSK轴承在油中摇晃几次，润滑脂也会从间隙中排出。

Bearings hardened with soft dry oil or antirust ointment should be soaked in oil at 100-200 degrees Celsius for a long time. The bearing is clamped, and grease on the bearings is cleaned with a brush. Soft dry oil or rust preventive ointment will melt when heated to 100-200 degrees Celsius. It is easy to wash away from bearing cracks. Sometimes, as long as the NSK bearing of Zhenjiang is swayed several times in the oil, the grease will also be discharged from the gap.

在清洗旧电机或进口电机的向心滚珠轴承时，滚珠、齿条及内圈应从外圈水平取出，然后浸入热油中。清洗短圆柱滚子轴承时，滚子、滚珠、内圈和外环也须清洗。

When cleaning the centripetal ball bearings of old or imported motors, the balls, racks and inner rings should be removed horizontally from the outer ring and then immersed in hot oil. When cleaning short cylindrical roller bearings, roller, ball, inner ring and outer ring must also be cleaned.

当热油被清洗时，油的温度不应超过200度。如果开火用于直接加热，应注意防止燃烧油。镇江NSK轴承须悬挂在油底壳中，底部会导致过热并降低硬度。

When the hot oil is cleaned, the temperature of the oil should not exceed 200 degrees. If firing is used for direct heating, attention should be paid to preventing burning oil. Zhenjiang NSK bearing must be suspended in the oil pan, the bottom will cause overheating and reduce hardness.

当轴承在煤油中浸泡5至10分钟时，一只手握住内圈，另一只手转动外圈，轴承上的干油或锈就会脱落。然后把轴承放在干净的煤油里，用软刷子刷洗，擦拭球和裂缝上的油，用***洗一次，然后取出来放在干净的纸上。滚珠、齿条、内圈和外圈在清洗向心滚珠轴承和短圆柱滚子轴承之前应分开，以便于清洗。

When the bearing is immersed in kerosene for 5 to 10 minutes, one hand holds the inner ring, and the other hand turns the outer ring, the dry oil or rust on the bearing will fall off. Then put the bearings in clean kerosene, wash them with a soft brush, wipe the oil from the balls and cracks, wash them with gasoline once, and then take them out and put them on clean paper. Ball, rack, inner ring and outer ring should be separated before cleaning centripetal ball bearings and short cylindrical roller bearings for easy cleaning.

安装在轴上的镇江NSK轴承主要由油枪或喷油枪清洗，油污容易清洗。先用煤油洗净，然后用***洗净。去除油渍很困难。先用100～200度的热油清洗或喷枪，然后用***洗净。小心不要用锋利的工具刮掉轴承上的硬脂或锈，以免损坏轴承滚子和槽环零件的平滑度。清洁轴承并用干净的软布擦拭。

The Zhenjiang NSK bearings installed on the shaft are mainly cleaned by oil guns or fuel injection guns, and oil stains are easy to clean. First wash with kerosene and then wash it with petrol. It is very difficult to remove oil stains. First use 100~200 degrees of hot oil to wash or spray gun, then wash with gasoline. Be careful not to scrape the stearin or rust off the bearing with sharp tools to ***oid damaging the ***oothness of the bearing rollers and groove ring parts. Clean the bearings and wipe them with clean soft cloth.

滚动轴承的内圈（也称为内套或内圈）通常固定在轴颈上，内圈随轴旋转。内圈的外圈有一个带有滚珠或滚子的凹槽，称为内槽或内滚道。

The inner ring of the rolling bearing (also known as the inner sleeve or inner ring) is usually fixed on the axle neck, and the inner ring rotates with the axle. The outer ring of the inner ring has a groove with balls or rollers, called internal grooves or inner raceways.

轴承直径，一般在轴与镇江NSK轴承直径之间紧密配合不好，长时间轴与轴承之间会发生内径与轴承间隙之间的摩擦，据说轴承在轴与轴承直径之间不起作用。R摩擦。相同的外径也是轴承的外径。轴承套筒不能通过轴承外径和轴承套筒摩擦力工作。

Bearing diameters, generally in the shaft and Zhenjiang NSK bearing diameters between the close fit is not good, long-term shaft and bearing will occur between the internal diameter and bearing clearance friction, it is said that the bearing between the shaft and bearing diameters do not work. R friction. The same outer diameter is also the outer diameter of the bearing. The bearing sleeve can not work through the bearing outer diameter and the bearing sleeve friction.

径向间隙的测量和调整是为了保证在运行中为内环、滚子及轴向径向热膨胀预留的径向间隙不会太小或太小，从而防止安装间隙在后期发生变化。在现阶段，我们应注意以下几点措施。如果安装间隙不满足，则应按照正常安装方法逐步调整安装间隙。

The measurement and adjustment of radial clearance is to ensure that the radial clearance reserved for inner ring, roller and axial radial thermal expansion in operation is not too ***all or too ***all, so as to prevent the installation clearance from changing in the later period. At this stage, we should pay attention to the following measures. If the installation gap is not satisfied, the installation clearance should be adjusted gradually according to the normal installation method.
