Description
Technical Field
[0001] The utility model relates to the technical field of bearings, in particular to a bearing end cover assembly oiling device. Background Art
[0002] Bearings are widely used in various equipment in modern industry. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. During the use of bearings, in order to prevent foreign matter from entering the bearings and affecting the use of the bearings, and in order to reduce the loss of lubricating grease, it is necessary to set a sealing cover on the surface of the bearings. When the mechanical and material properties of the bearings themselves have not reached their design life, properly adding or replacing lubricating grease to the bearings after working in a high-temperature environment can effectively reduce the number of bearing spare parts and achieve the purpose of energy saving and consumption reduction. When adding new lubricating oil to the bearings, it is necessary to first remove the old metal dust cover, clean the old lubricating grease and inject new lubricating grease, and then re-press the new metal dust sealing cover. However, the existing bearing oiling equipment does not have a centering structure when clamping the bearings, and the end cover cannot be installed after oiling. Therefore, it is necessary to design a bearing end cover assembly oiling equipment. Utility Model Content
