Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packing rings, in particular to a self-lubricating combined packing ring. Background Art
[0002] A packing ring is a ring of material that is inserted into a pressure connection to form a tight seal. Depending on the specific situation, packing rings are also called sealing rings or O-rings, or simply packing. They are used in various mechanical and pressurized systems to control pressure and prevent leaks. Replacement parts are available for various systems through hardware and specialty stores. Self-lubricating bearings, also known as graphite copper sleeves, are a metal material as the matrix, using graphite and silver disulfide as solid lubricants. They are made through a special process so that the solid lubricant has uniform gaps and can contain a certain amount of lubricating oil. When working under oil-free conditions, the lubricating oil and solid lubricant are combined through friction heat and gradually distributed to the friction surface to achieve a small friction coefficient and good wear resistance. The interval between lubrication maintenance can be greatly extended. It delivers an appropriate amount of lubricating oil to the rolling surface of the steel ball without causing pollution to the surrounding area, so it is an environmentally friendly lubrication system.
