外形精度改变的南京NSK轴承无极限运用

润滑脂对南京NSK轴承有良好的影响。具有良好的附着力、耐磨性、耐温性、防锈性和润滑性。可提高机械的高温不被氧化性，延缓老化，溶解碳，防止金属废料和油的团聚，提高机械的耐磨性、耐压性和耐腐蚀性。

Grease has a good effect on NSK bearing in Nanjing. It has good adhesion, wear resistance, temperature resistance, rust resistance and lubricity. It can improve the high-temperature non-oxidation of machinery, delay aging, dissolve carbon, prevent the agglomeration of metal waste and oil, improve the wear resistance, pressure resistance and corrosion resistance of machinery.

然而，如果填充了南京NSK轴承润滑脂，摩擦扭矩越大。对于相同填充量，密封轴承的摩擦力矩大于开式轴承的摩擦力矩。当润滑脂的量相当于轴承内部空间体积的60个百分点时，摩擦力矩将不再显著增加。这是因为开式轴承中的大部分油已经被挤压，密封轴承中的润滑脂已经丢失。

However, if the Nanjing NSK bearing grease is filled, the greater the friction torque is. For the same amount of filling, the friction torque of the sealed bearing is greater than the friction torque of the open bearing. When the amount of grease is equal to 60 percent of the bearing internal space volume, the friction torque will not increase significantly. This is because most of the oil in open bearings has been squeezed and grease in sealed bearings has been lost.

南京NSK轴承温度随填充温度的增加呈线性增加。在相同充液条件下，密封轴承的温度高于开式轴承的温度。一般认为，密封滚动轴承的润滑脂量不大于内部空间的50个百分点。

The bearing temperature of NSK increases linearly with the increase of filling temperature in Nanjing. Under the same liquid filling condition, the temperature of the sealed bearing is higher than that of the open bearing. It is generally believed that the grease content of sealed rolling bearings is not greater than 50 percentage points of internal space.

一般来说，轴承的润滑方案是基于时间的。设备供应商通常根据操作时间制定润滑计划。此外，设备供应商在其维护计划中经常参与润滑油量的指导。短期更换润滑剂是一种常见的做法，工作人员往往会增加侧脂肪。

Generally speaking, the lubrication scheme of bearings is based on time. Equipment suppliers usually make lubrication plans according to the operating time. In addition, equipment suppliers often participate in the guidance of lubricant quantity in their maintenance plan. Short term replacement of lubricants is a common practice, and staff often increase side fat.

在磨削前，应更加精细控制轴承通道磨削形状的基本精度，在磨削过程中应精细控制轴承通道的精度。

Before grinding, the basic precision of the grinding shape of the bearing passage should be more precisely controlled, and the precision of the bearing passage should be precisely controlled in the grinding process.

超精加工设备主要零件的制造精度也会严重影响南京NSK轴承超精加工工件的沟道形状的变化。残留超磨床不仅可以提高磨削加工的形状精度，而且会***磨削加工的形状精度。

The manufacturing accuracy of the main parts of the superfinishing equipment will also seriously affect the channel shape of the superfinishing workpiece of Nanjing NSK bearing. Residual super grinding machine can not only improve the shape accuracy of grinding, but also destroy the shape accuracy of grinding.

超精加工余量的大小不仅与超精加工的节奏有关，而且与超精加工后轴承通道的外观质量有关。

The magnitude of superfinishing allowance is not only related to the rhythm of superfinishing, but also to the appearance quality of bearing passage after superfinishing.

在低成本轴承市场上，我国南京NSK轴承企业在选择低成本超机械机床方面积累了很多长期的经验，尽管这些做法依赖于许多技术人员提出的主观因素。在空调和电机市场，我们的微型和小型轴承取得了显著的销售业绩，部分原因是由于轴承制造设备的发展和进步，虽然这些发展并不稳定，但暂时中断。中国的地方质量水平是无法控制的。它可以由客户承担。

In the low-cost bearing market, Nanjing NSK bearing enterprises in China h***e accumulated a lot of long-term experience in choosing low-cost super-mechanical machine tools, although these practices rely on subjective factors put forward by many technicians. In the air conditioning and motor markets, our micro and ***all bearings h***e achieved remarkable sales results, in part because of the development and progress of bearing manufacturing equipment, although these developments are not stable, but temporarily interrupted. China's local quality level is beyond control. It can be undertaken by customers.
