High temperature spindle bearing design requirements can choose the performance of the grease

Choose the spindle bearing high temperature grease what performance requirements is 1. Good smoothness between the spindle and high temperature bearing interface can stick to the average oil film, and in the development of the spindle start or stop motion produced a certain impact load of oil film is not destroyed, insist on a good smooth performance, play an effective to reduce the trade friction and the friction heat, lowering the temperature rise of the main shaft, ensure enterprise main machining method accuracy request product quality has a good smoothness. 2. Good rust resistance in the process of spindle smooth system operation, oil do not mix with air cooling fluid or machine tool in condensate, require oil has good rustproof, especially in the southern humid and hot climate regions, should pay special attention to the rust protection. 3. Good oxidation resistance of the machine tool main sleeve when using a recycle smooth handling. Request for the long-term development of the high temperature bearing spindle oil use and the same, will not produce for swimming mud and oil corrosion and high temperature bearing clearance, to produce small infarct main effect, thus can request product quality has a good resistance to oxidation stability, industry of our country economy management specification oil oxidation stability index of the network request for 1000 h ( ( GB / T, 12581) 。 4. Suitable strength and good thermal performance in order to prevent the machine's main uranium caused by high temperature machine tool thermal deformation, affect the machining accuracy or make high temperature bearing is not smooth, should according to the high temperature of bearing spindle structure, rotational speed and high temperature bearing clearance smooth well choose appropriate maturity with good temperature characteristic, avoid the spindle working temperature and the change of environmental temperature, degree of changes which affect the smooth performance. High temperature bearing an important part of modern mechanical equipment. Its main function is to support the body of revolution, mechanically to reduce the friction coefficient during the movement, The coefficient of friction) , and ensure the accuracy of the rotation. Adhere to the high temperature in high speed bearing demand level off, smooth grease suitable talents, in order to ensure timely and smooth, make the normal operation of our machine, and also extend the service life of the spindle bearing temperature.
