安装镇江INA轴承NA4924前与运作中的故障排查

Appearance inspection before bearing installation:

1。检查是否有各种机械伤痕，如磨损、划痕、划痕等，将形成不太好的轴承装置，造成偏载和应力集中，导致精度不准确。

1. Check whether there are various mechanical scars, such as wear, scratches, scratches, etc., will form a poor bearing device, resulting in bias load and stress concentration, resulting in inaccurate accuracy.

2。看镇江INA轴承表面是否会生锈，黑色表面和凹坑，背面两处容易积存水分和污垢缺点，很容易发展成腐蚀。腐蚀是一种污染源，它可能导致设备不足、早期磨损和疲劳。严重的腐蚀会导致浪费。

2. See whether the surface of Zhenjiang INA bearing will rust, black surface and pit, back two easy to accumulate water and dirt shortcomings, easy to develop into corrosion. Corrosion is a source of pollution, which may lead to inadequate equipment, early wear and fatigue. Serious corrosion can lead to waste.

3。仔细观察轴承裂纹，如原始数据中的裂纹、锻造裂纹、热处理裂纹和磨削裂纹。这些裂纹在轴承运行后期会成为应力集中源，并迅速扩展形成轴承。裂纹、镇江INA轴承寿命和工作稳定性受到很大影响。

3. Careful observation of bearing cracks, such as cracks in the original data, forging cracks, heat treatment cracks and grinding cracks. These cracks will become stress concentration sources in the later stage of bearing operation, and will rapidly expand to form bearings. Cracks, Zhenjiang INA bearing life and work stability has been greatly affected.

在检查前，须清理机床表面，并清理掉机床主轴轴承周围的零件。油封是一个非常脆弱的部件，需要小心拆卸，不要用力过度，然后仔细检查油封及其周边部件，如果有非正常症状，须更换，油封不严谨将导致轴承损坏和严格设备停机。

Before the inspection, the machine tool surface must be cleaned and the parts around the spindle bearing of the machine tool should be cleaned. Oil seal is a very fragile part, need to be carefully removed, do not overexert, and then carefully check the oil seal and its peripheral parts, if there are abnormal symptoms, must be replaced, improper oil seal will lead to bearing damage and strict equipment shutdown.

检查润滑剂，蘸一点润滑剂在手指的摩擦力，如果有污染物，可以诱发，或在手背上涂上一层薄薄的润滑剂，然后进行密封检查。

Check the lubricant, dip a little lubricant in the finger friction, if there are contaminants, can be induced, or on the back of the hand coated with a thin layer of lubricant, and then seal inspection.

更换润滑油。润滑油润滑后，清洗机床主轴镇江INA轴承上的旧油。然后倒入新鲜油，让机器以低速旋转几分钟。油尽可能收集残留的污染物，然后清洗油。油在使用前应过滤。

Replace lubricating oil. After lubricating the lubricating oil, clean the old oil on the INA bearing of the machine spindle, Zhenjiang. Then pour in fresh oil and allow the machine to spin at low speed for a few minutes. As far as possible, oil can collect residual contaminants and then clean the oil. Oil should be filtered before use.

1。选油：选油一般是根据机床主轴轴承转速、耐温性、噪声要求和起动转矩来选择的，对各种油的要求都非常了解。

1. Oil selection: Oil selection is generally based on machine tool spindle bearing speed, temperature resistance, noise requirements and starting torque to choose, all kinds of oil requirements are very well understood.

镇江INA轴承密封型式的选择：机床主轴轴承润滑可分为油润滑和润滑脂润滑。油润滑轴承通常由轴承制成，而油润滑轴承通常由防尘罩或橡胶密封件覆盖。防尘罩适用于高温或良好的工作环境。密封件分为接触式密封和非接触式密封两种。接触密封具有良好的防尘性能，但起动力矩较大。非接触式密封具有较小的起动力矩，但其密封性能不如其接触密封性能好。

Zhenjiang INA bearing sealing type selection: machine tool spindle bearing lubrication can be divided into oil lubrication and grease lubrication. Oil-lubricated bearings are usually made of bearings, and oil-lubricated bearings are usually covered by dust shields or rubber seals. Dust cover is suitable for high temperature or good working environment. Seals are divided into two types: contact seal and non-contact seal. The contact seal has good dustproof performance, but the starting torque is large. The non-contact seal has smaller starting torque, but its sealing performance is not as good as its contact sealing performance.

三。轴承选择：轴承选择一般是根据使用配套产品和轴承负荷对机床主轴轴承进行选择。因此，有必要知道用户的实际负载是否满足所选轴承的要求。如果镇江INA轴承不能满足使用要求，应尽快更换，但除非特殊产品一般没有相对应用。

Three. Bearing selection: Bearing selection is generally based on the use of supporting products and bearing load on the machine tool spindle bearing selection. Therefore, it is necessary to know whether the actual load of the user meets the requirements of the selected bearings. If Zhenjiang INA bearings can not meet the requirements of use, should be replaced as soon as possible, but unless the special products are generally not relatively applied.
