Description
The technical field is as follows:
the invention belongs to the field of sliding bearing design, and particularly relates to a lubricating method of a water-lubricated bearing based on micro-oil drop lubrication start-stop protection.
Background art:
the bearing is used as a key part in mechanical transmission and is widely applied in industry. The load, the rotating speed and the temperature of the bearing are different under different working conditions and are influenced by various impurities, so that the design and the lubrication mode of the bearing need to be correspondingly adjusted according to different working environments. The traditional bearing lubrication mostly uses oil as a lubricating medium, a large amount of oil resources are consumed, and in order to prevent leakage, the bearing needs to be sealed, so that the bearing structure is complex.
In order to meet the continuous development of industrial technology in China and the technical requirements on ocean engineering equipment and high-tech ships, the service life and the performance of the bearing used in water for a long time are improved. In order to overcome the waste of resources and environmental pollution caused by oil-lubricated bearings, water-lubricated bearings using water as a lubricating medium are available in the market. Compared with an oil lubrication bearing, the water lubrication bearing has the characteristics of simple structure, cleanness, environmental protection, low cost and the like. However, because the viscosity of water is low and the bearing capacity of a water film is poor, the water-lubricated bearing is in a mixed lubrication state or even a boundary lubrication state under the starting and stopping states and the low-speed working condition, so that the bearing material is easily abraded, and the service life and the operation performance of the bearing are seriously influenced. Therefore, the water lubrication bearing based on micro-oil drop lubrication start-stop protection is designed, and a proper lubrication mode can be selected according to different rotating speeds of the bearing so as to improve the lubrication effect of the bearing.
The coordinate characterization S0 in the stribeck curve, i.e. viscosity x speed/load, i.e. the number of Sommerfelds in fluid lubrication, can be seen from the stribeck curve with the abscissa S0The numerical value of (2) is increased, the clearance h between the friction pairs is continuously increased, the bearing lubrication state is gradually changed from boundary lubrication and mixed lubrication into dynamic pressure lubrication, and the bearing lubrication performance is continuously improved. In the case of the water-lubricated sliding bearing, the load W and the viscosity mu of the lubricating medium are constant, so that S is0With the increase of the rotating speed of the bearing, the thickness of the lubricating oil film in the bearing is increased continuously, and the lubricating state is switched from boundary lubrication to mixed lubrication and then to hydrodynamic lubrication. Because the bearing is seriously worn under the conditions of boundary lubrication and mixed lubrication, a critical speed can be calculated through a Stribeck (stribeck) curve, and when the rotating speed of the bearing is lower than the critical speed, the bearing is in a boundary or mixed lubrication stage, so that the bearing material is easily worn; only when the rotating speed of the bearing is higher than the speed, the bearing can be in hydrodynamic lubrication, the friction pair can be effectively isolated by a water film to form good lubrication, and the kinematic viscosity v of water at 20 ℃ is 1.005 multiplied by 10^ (-6) (m) due to the low viscosity of water2And/s) and the critical rotating speed is higher, so that the bearing is in the boundary and the mixed lubrication time is longer in the start-stop stage, the bearing abrasion is easily caused, and the service life and the performance of the bearing are influenced. Therefore, the lubricating method for the water-lubricated bearing based on micro-oil drop lubrication start-stop protection is designed and prepared, the bearing can be effectively protected and abrasion can be reduced by a mixed lubrication mode during start-stop.
The invention content is as follows:
