然而，就这些问题来说，如果设计人员没有充分学握润滑技术，就难以考虑使用温度和周围介质、承载条件和设备重要件等因素来选择最合适的润滑剂和润滑方法。如果在设计阶段决定的轴承和润滑方法不合适，则轴承加热器一旦制成，要改成其他形式就非常困难了。如果要改，就需花费很高的费用和很长的改造时间。此外，就制造时的配合、表面粗糙度及装配精度等的合适值来说，往往要依靠经验，通常要联系制造成本来进行通盘考虑。在这方面，各厂都有许多实际经验。由此可见，必须由具有丰富经验的润滑技术人员在设计时对润滑关系进行校验。
In the design stage of bearing heater, the relationship between the lubrication technology and the reliability of the bearing heater is the most closely. The bearing, gear and seal used in the bearing heater are suitable for the lubrication of the machine parts, and even determine the life of the bearing heater. But from the perspective of the use of machinery and equipment selection of lubrication methods and lubricants, and its importance is no less than this.
However, on these issues, if the designers are not fully learn grip lubrication technology, it is difficult to consider the use of the temperature and the surrounding medium, loading conditions and equipment important factors to select the most suitable lubricant and lubrication method. If the bearings and lubrication methods are not suitable in the design stage, the bearing heater once made, it is very difficult to change to other forms. If you want to change, it is necessary to spend a high cost and a long time of transformation. In addition, on the proper value of coordination, the manufacture of surface roughness and assembly accuracy, often have to rely on experience, usually need to contact the manufacturing cost to take into consideration. In this regard, the plant has a lot of practical experience. Thus, it is necessary to check the lubrication relationship in the design of the lubrication technical personnel with rich experience.
