The performance of the lubricating oil used for INA universal joint bearing and the influence of life - bearing of knowledge

INA bearing lubricating oil can be broadly divided into two major categories of lithium and calcium base. Vibration control system can help to solve the problem. The system is based on LM guide application technology of ball screw in the earthquake can provide protection for people's life and life. The system not only can prevent the damage caused by earthquake, lithium base relative to calcium base grease has excellent water resistance, mechanical stability, chemical stability, lithium soap thickening ability is stronger, extreme pressure agent is added in the grease, rust and other additives, made from a variety of long-life grease. But also because of their ubiquitous, reliable, durable and reduce people's panic, brick machine bearings use conditions, time is long, heavy load, maintenance difficulties, so most use lithium base grease. If INA bearings with iron filings, burr, dust and other foreign matter to enter, will make the universal joint bearing noise and vibration during operation, even damage raceway and rolling body. So before the installation of bearings, must ensure that the installation surface and the environment clean. Lubrication of INA bearings work and life have very important influence. Grease made out of base oil, thickener and additive. The performance of the grease is mainly determined by the base oil. The basis of generally low viscosity oil is suitable for low temperature, high speed; High viscosity is suitable for high temperature, high load. Thickener and relationship with lubrication performance, thickening agent, water resistance to the water resistance of the grease. In principle, different brand of grease can't mix, and even the same thickening agent of grease, will also bring bad influence each other on the basis of different additives. Universal joint bearing surface coated with anti-rust oil, must use clean petrol or kerosene cleaning carefully, then coated with clean, high quality or high speed high temperature lubricating grease before installation. Fully enclosed bearing not clean fuel. After INA bearings installed, if not done carefully alignment, alignment can lead to bearing suffered another load, friction, and vibration. The use of these may accelerate fatigue and reduce the bearing life, and it might damage the other machine parts service life. In addition, the increase of vibration and friction could significantly increase the risk of energy consumption and premature failure. During the period of using, often should run of universal joint bearing of basic external condition monitoring, such as temperature, vibration and noise measurement, etc. These regular check will help identify potential problems and to prevent unexpected machine to suspend the phenomenon, make the production plan, improve plant productivity and efficiency. In the process of operation, INA bearing requires correct lubrication again, perfect its performance. The method of bearing lubrication, divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, to choose suitable for conditions of use, the purpose of lubrication method. If only consider lubrication and oil lubrication. But there are grease lubrication can simplify the structure of universal joint bearing around specialty.
