Description
Technical Field
The invention relates to the technical field of lubricating grease, in particular to lubricating grease applied to a main shaft bearing of wind power generation equipment and a preparation method thereof.
Technical Field
In recent 20 years, wind power technology is mature day by day, the application scale is larger and larger, and the installed capacity is continuously increased. The development of renewable energy represented by wind power has become a long-term strategy for coping with future energy and climate change pressure in countries in the world. From 1986, the first wind power plant established in Shandong in China to date, and the accumulated installed capacity of wind power is the first place in the world. The development prospect of the wind power industry is good, so that the development of related research work for improving the performance of a wind power lubricating system and prolonging the service life of wind power equipment has good economic and social benefits. Statistically, most faults of the wind driven generator are related to bearings, and about 80% of bearing failures are related to lubrication, so that the problem related to bearing lubrication is urgently needed to be solved.
The wind power main shaft grease is mainly used for lubricating a main shaft bearing of large-scale wind power generation equipment, and the performance requirement of the wind power main shaft grease is determined by the specific working condition and the lubricating characteristic of the main shaft bearing of the wind power generation equipment. The wind driven generator works on the principle that kinetic energy of air flow acts on the impeller and is converted into mechanical energy to push the impeller to rotate, and a rotating shaft of the impeller is connected with a rotating shaft of the generator through a gearbox to drive the generator to generate electricity. The main parts of the wind driven generator comprise a blade bearing, a main bearing, a gear box, a generator bearing, a yaw system bearing, a gear and the like. Because the wind field where the wind turbine generator is located has high wind speed fluctuation, the operating conditions are complex and changeable, and some wind turbine generators even face extremely severe extreme environmental conditions such as high altitude, high temperature, strong wind, strong dust and the like. Therefore, the performance of the bearing grease of the wind turbine generator has very important influence on the normal operation of the machine.
Fretting wear of a main shaft bearing of the wind driven generator fails, and in severe cases, the fretting crack of the bearing is initiated to be initiated, expanded, even broken and failed, so that the bearing is damaged, and the fretting wear becomes a primary factor restricting the running reliability and the service life of the bearing. However, at present, research reports about wind power bearing lubricating grease are rarely found, so that research on wind power bearing lubricating grease and frictional wear performance thereof is carried out, and especially, the research on fretting wear resistance of wind power bearing lubricating grease is of great significance.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide the fretting wear resistant fan main shaft bearing lubricating grease and the preparation method thereof. The preparation method can effectively improve the fretting wear resistance of the bearing grease, and ensure that the bearing grease still has good thermal oxidation stability, rust prevention, corrosion prevention and extreme pressure wear resistance under the severe environments and working conditions of sand, snow, rain, salt mist erosion and the like.
The invention relates to fretting wear resistant fan spindle bearing lubricating grease which comprises the following components in parts by weight: 73-91 parts of base oil, 8-16 parts of thickening agent, 1-5 parts of anti-wear and anti-wear agent, 1-3 parts of antioxidant, 0.5-2 parts of extreme pressure anti-wear agent, 0.5-1.5 parts of antirust agent and 0.5-1.5 parts of metal corrosion inhibitor.
Further, the base oil is composed of a poly α -olefin synthetic base oil and an alkylnaphthalene synthetic base oil.
Further, the mass ratio of the poly α -olefin synthetic base oil to the alkyl naphthalene synthetic base oil is 1-3: 3-1.
Further, the thickening agent is fatty acid composite metal soap.
Further, the antiwear and antifriction agent is molybdenum dialkyl dithiocarbamate.
Furthermore, the antioxidant consists of a main antioxidant and an auxiliary antioxidant, wherein the main antioxidant is a diphenylamine derivative, and the auxiliary antioxidant is molybdenum dialkyl dithiocarbamate. The molybdenum dialkyl dithiocarbamate is a multifunctional agent and has synergistic antioxidation with arylamine antioxidant.
Further, the extreme pressure antiwear agent is a phosphate derivative.
Further, the antirust agent is composed of any one or more of barium petroleum sulfonate, barium nonyl naphthalene sulfonate and neutral barium dinonyl naphthalene sulfonate.
Further, the metal corrosion inhibitor is a thiadiazole derivative.
More optimally, the inventor finds through a large number of experiments that when the mass ratio of each component is respectively 12% of fatty acid composite metal soap, 60% of poly α -olefin synthetic base oil, 22% of alkyl naphthalene synthetic base oil, 1.5% of diphenylamine derivative, 2.5% of molybdenum dialkyl dithiocarbamate, 0.5% of thiadiazole derivative, 0.5% of neutral barium dinonyl sulfonate and 1.0% of phosphate ester derivative, the optimal matching among the service performances of the lubricating grease can be realized, and particularly, the lubricating grease shows excellent fretting wear resistance.
The invention also provides a preparation method of the fretting wear resistant fan spindle bearing lubricating grease, which comprises the steps of weighing poly α -olefin synthetic base oil and alkyl naphthalene synthetic base oil accounting for 65-80% of the total amount of the base oil in a reaction kettle, heating to 75-80 ℃, adding fatty acid complex metal soap, heating to 210-230 ℃, refining at high temperature for 10min, adding the rest of the base oil, cooling, dispersing at constant temperature for 30-40 min when the temperature is reduced to 185-188 ℃, respectively adding all the anti-wear and anti-wear agents, the main antioxidant, the auxiliary antioxidant, the extreme pressure anti-wear agent, the antirust agent and the metal corrosion inhibitor when the temperature is reduced to 80-110 ℃, and then carrying out homogenization and degassing to obtain the finished product of the fretting wear resistant fan spindle bearing lubricating grease.

The fan main shaft bearing lubricating grease has excellent waterproof performance and corrosion resistance so as to ensure that the main shaft bearing is prevented from being corroded by the environment. The indexes of the water-resistant, corrosion-resistant and rust-proof performance of the lubricating grease are shown in table 1.
TABLE 1 Water-resistant, anticorrosive and antirust indexes of the lubricating grease of the present invention
The domestic wind field is wide, the ambient temperature is about-40 to 40 ℃, and the wind field is frequently stopped and started. The lubricating grease for the main shaft bearing of the fan is required to ensure that the main shaft bearing of the wind generating set can be started and operated at low temperature, namely low-temperature lubricity. The high and low temperature performance indexes of the grease of the present invention are shown in table 2.
TABLE 2 high and low temperature Performance indices of the greases of the present invention
When the wind speed is higher, the axial force from the impeller born on the main shaft is larger, so that the rolling bodies of the back row bearing move backwards, the gap between the rolling bodies and the inner and outer rings is reduced, the friction is increased, the temperature of the bearing is increased, and serious abrasion is caused. Fretting wear is an index reflecting the wear resistance of a grease under a periodic small amplitude state. The fan is influenced by irregular strong wind in the field, and the vibration generated by the equipment can directly act on the main shaft bearing, the yaw bearing and the variable pitch bearing, so that the main shaft bearing lubricating grease needs to have the fretting wear resistance. The extreme pressure antiwear and fretting wear resistant performance indexes of the lubricating grease are shown in table 3.
TABLE 3 extreme pressure antiwear and fretting wear resistance performance index of the grease of the present invention
The data show that compared with the prior lubricating grease, the lubricating grease of the invention has improved water-resistant anti-corrosion and anti-rust performance, high and low temperature performance and extreme pressure anti-wear performance. Particularly, the fretting wear resistance is greatly improved compared with the prior lubricating grease.
Comparative example performance indices for greases according to the invention are set forth in table 4.
TABLE 4 comparative example Performance index for greases according to the invention
Comparative example 1 and the examples of the application compare, the composition differs from the application in that the thickening agent is a prefabricated tetraurea thickening agent, the metal corrosion inhibitor is a benzotriazole derivative, and the extreme pressure antiwear agent is a nitrogen-containing sulfur phosphate derivative, but the mixture ratio is the same as the application. Compared with the lubricating grease of the invention, the extreme pressure anti-wear and anti-fretting wear performance of the lubricating grease is greatly different, and especially the fretting wear performance, the friction coefficient of the SRV anti-fretting wear test, the top ball diameter and the like of the lubricating grease exceed the requirements of the existing related performance indexes. Comparative example 2 and examples of the present application compare, the composition is the same as the present application, but the ratio is different from the present application. Under the proportion of the additives in the comparative example, the additives cannot achieve better synergistic effect, the extreme pressure wear resistance and fretting wear resistance of the lubricating grease are slightly better than those in the comparative example 1, but the extreme pressure wear resistance and fretting wear resistance of the lubricating grease are still poorer than those in the lubricating grease of the invention, and the friction coefficient, the top ball diameter and the like of an SRV fretting wear resistance test exceed the requirements of the existing related performance indexes.
Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that various changes, modifications and substitutions can be made without departing from the spirit and scope of the invention as defined by the appended claims. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
