Description
Technical Field
The invention relates to a bearing working in a high-temperature (above 500 ℃) environment, in particular to a gas-phase and gas/solid-phase in-situ polymerization solid lubrication system of a high-temperature rolling bearing, which generates a solid lubrication film through in-situ polymerization reaction of a gas-phase monomer at high temperature so as to provide the antifriction and wear-resistant effects of the bearing.
Background
Due to the development and progress of science and technology, the working temperature of machinery is higher and higher under the requirements of special industries such as aviation aircrafts, steel making and the like, and the problem of high-temperature lubrication of supporting elements, bearings, transmission elements and gears in mechanical devices is more and more prominent. The lubricating grease which is generally used can only be used at 150 ℃, and cannot cope with the lubricating problem at higher temperature. The self-lubricating preset material is generally adopted at higher temperature, so that the part has higher mechanical strength, the preparation process is simple and convenient, and the self-lubricating preset material is suitable for parts with various sizes, thereby being an effective way for realizing high-temperature solid lubrication.
The preset self-lubricating coating can be quickly consumed in the friction process at high temperature, so that the lubricating effect is reduced or even disappears, and the friction reducing and wear resisting effects on the parts cannot be realized. Subsequent replenishment of the pre-set coating after it has been consumed is a problem and generally requires disassembly of the component and application of the coating before reassembly. In order to solve the problem of replenishment of the lubricating coating after consumption, vapor deposition of a lubricating material is proposed, wherein a gas material is convenient to convey and replenish, the commonly adopted vapor deposition lubricating materials comprise a hydrocarbon vapor deposition lubricating material and a phosphate vapor deposition lubricating material, and the vapor deposition lubricating films have the advantages that the gas material can be continuously replenished, and the lubricating effect can be continuous. The deposited film has the defects of low molecular weight, unobvious antifriction and wear-resistant effects, rapid decomposition of the deposited film at higher temperature, short time for exerting the solid lubricating effect, lower molecular weight of decomposition products including deposited carbon and more limited lubricating effect. Therefore, it is necessary to develop a bearing used in high temperature environment and a high-efficiency lubricating method which can be continuously supplemented to provide antifriction and antiwear effects.
