In recent years, with the development of science and technology, crossed roller bearings have become an indispensable part of precision science and technology research. According to the survey, about 60% of domestic bearing orders come from imported bearings. In addition to the trust in the popularity of imported products, the variety of products, high precision and wide adaptability are also advantages that products cannot overcome. Throughout the internal bearing manufacturers, most of the varieties are not or not refined, resulting in the production of bearings not recognized.
As one of the imported bearings, how to properly lubricate the bearings is an important part of bearing maintenance and maintenance during normal operation.
1. Oil bath smooth
Oil bath lubrication is a common lubrication method in thin-walled crossed roller bearings, suitable for the lubrication of low and medium speed bearings. The bearing is partially immersed in the groove, and the lubricating oil is brought up by the rotating bearing parts, and then flows back to the oil groove. The oil level should be slightly lower than the center of the rolling element.
2. Drip oil and smooth
Oil dripping lubrication is suitable for thrust cylindrical roller bearing components that require quantitative supply of lubricating oil. The amount of oil dripping is preferably every 3-8 seconds. Too much oil will cause the bearing temperature to increase.
3. Circulating oil to lubricate
The filtered oil is transported to the crossed roller bearing by the oil pump, and the lubricating oil after passing through the bearing is filtered and cooled before use. Because the circulating oil can take away a certain amount of heat and cool the bearing, this method is suitable for bearing parts with high rotation speed.
