数控机床轴承常见的质量问题主要原因是哪些在设备数控机床轴承时，金星机床

The common quality problems of CNC machine tool bearings are mainly due <br><br>to the pre-loading of the Venus machine tool when the CNC machine tool bearings are installed, so that the original clearance after the bearing equipment will be eliminated, then the contact angle and accuracy of the CNC machine tool bearings It has <br><br>a very important effect. Therefore, in the equipment bearing, it is necessary to ensure that the contact angle is qualified, and it is also necessary to ensure that the practical width of the angular contact ball bearing meets the regulations. The bearing was in operation during <br><br>the current problems are common, so do not make a fuss. The problem is presented, and discrimination and handling are the key. <br><br>I. Improper equipment <br><br>1. Use brute force in the equipment and directly hit the bearing with a hammer to cause great damage to the bearing; it is the main reason for the deformation. This is very common in some small machine tool factories. Venus machine tools use professional bearing equipment tools in bearing equipment, and then prevent this. <br><br>2. The equipment is not in place, the equipment has deviations or is not installed in the bearing position, resulting in too small bearing clearance. The inner and outer rings are not at the same center of rotation, forming a concentricity. <br><br>Proposal: Select appropriate or professional bearing equipment tools, and use special instruments to test after the equipment is completed. <br><br>2. Poor smoothness <br><br>According to the investigation, poor smoothness is one of the main causes of premature bearing damage. The main reasons include: failure to add lubricant or lubricant in time; lubricant or lubricant not filled in place; improper selection of lubricant or lubricant; incorrect method of smoothing, etc. <br><br>Proposal: Choose the correct smoothing agent or oil, and use the correct smooth filling method. <br><br>3. Pollution <br><br>Pollution can also lead to premature bearing damage. Pollution means that dust, metal shavings, etc. enter the bearing. The main reasons include: turning the bearing packaging prematurely before use to form pollution; the working environment of the equipment is not clean and forming pollution; the working environment of the bearing is not clean and the working medium is polluted. All the spindle equipment of Jinxing Machine Tool is completed in a constant temperature clean room, and then the bearing pollution is prevented. <br><br>Proposal: Be careful not to unpack the bearing before use; insist on the cleaning of the equipment environment when cleaning the equipment, clean the bearing to be used; strengthen the sealing equipment of the bearing. <br><br>Four, tired<br><br>Fatigue damage is a common method of bearing damage. Common causes of fatigue and damage may be: long-term overloading of bearings; failure to repair in time; improper repair; equipment aging, etc. <br><br>5. Bearing quality The quality of the <br><br>bearing itself is directly related to the service life. Our factory uses imported bearings or domestic first-line brands, and then prevents this problem.

数控机床轴承常见的质量问题主要原因是哪些<br><br>在设备数控机床轴承时，金星机床都要进行预加载荷，这样轴承设备后原始的游隙就会消除，那么就是说数控机床轴承的接触角与精度有<br><br>着非常重要的效果。因此在设备轴承时，要保证接触角合格的同时也有必要保证角接触球轴承实践宽度符合规定。 轴承在运转过程中呈<br><br>现毛病是常有的事，所以不必大惊小怪的。呈现了毛病，判别并处理是关键。<br><br>一、设备不妥<br><br>1、设备时运用蛮力，用锤子直接敲击轴承对轴承损伤很大；是形成变形的主要原因。这一点在一些小型的机床厂非常常见，金星机床在设备轴承时运用了专业的轴承设备工具，然后防止了这一点。<br><br>2、设备不到位，设备有偏差或未装到轴承位，形成轴承游隙过小。内外圈不处于同一旋转中心，形成不同心。<br><br>主张：挑选适当的或专业的轴承设备工具，设备完毕要用专用仪器检测。<br><br>二、光滑不良<br><br>据调查，光滑不良是形成轴承过早损坏的主要原因之一。主要原因包含：未及时加注光滑剂或光滑油；光滑剂或光滑油未加注到位；光滑剂或光滑油选型不妥；光滑方法不正确等等。<br><br>主张：挑选正确的光滑剂或光滑油，运用正确的光滑加注方法。<br><br>三、污染<br><br>污染也会导致轴承过早损坏，污染是指有沙尘、金属屑等进入轴承内部。主要原因包含：运用前过早翻开轴承包装，形成污染；设备时工作环境不清洁，形成污染；轴承的工作环境不清洁，工作介质污染等。金星机床所有的主轴设备都是在恒温清洁室完成，然后防止了轴承污染。<br><br>主张：在运用前注意不要拆开轴承的包装；设备时坚持设备环境的清洁，对要运用的轴承进行清洗；增强轴承的密封设备。<br><br>四、 疲惫<br><br>疲惫破坏是轴承常见的损坏方法。常见的疲惫破坏的原因可能是：轴承长时间超负荷运行；未及时修理；修理不妥；设备老化等。<br><br>五、轴承的质量<br><br>轴承本身质量的好坏直接关系到运用寿命，我厂全部运用进口轴承或者国产一线品牌，然后防止的这个问题。

What are the main reasons for the common quality problems of bearings in CNC machine tools<br>In the bearing of CNC machine tools, Venus machine tools must be preloaded, so that the original clearance after bearing equipment will be eliminated, that is to say, the contact angle and accuracy of CNC machine bearings are<br>It has a very important effect. Therefore, it is necessary to ensure that the practical width of the angular contact ball bearing meets the requirements while the contact angle is qualified. During the operation of the bearing<br>There are always problems, so don't make a fuss. The key is to distinguish and deal with the problems.<br>1、 Improper equipment<br>1. Using brute force and hammering the bearing directly is the main cause of deformation. This is very common in some small machine tool factories.
