Description

Technical Field

[0001] The invention relates to the field of sliding bearings, in particular to an oil-gas mixed lubrication high-efficiency cooling sliding bearing and a cooling method thereof. Background Art

[0002] Sliding bearings are a common type of bearing that supports rotating or reciprocating shafts through sliding friction. They consist of a bearing housing and a bushing, typically made of a wear-resistant material (such as bronze, babbitt metal, or polymer). During operation, a lubricant (oil or grease) forms a film on the friction surface to reduce friction and wear. Sliding bearings offer a simple structure, strong load-bearing capacity, impact resistance, and smooth operation. They are suitable for low-speed, heavy-load, or high-precision applications (such as internal combustion engines, turbines, and machine tools). Based on the lubrication method, they can be categorized as hydrodynamic, hydrostatic, and self-lubricating bearings, and are widely used in industrial machinery and transportation equipment.

[0003] The existing sliding bearings can specifically refer to a seat-type sliding bearing with application number CN202322894308.2, which includes: a sliding bearing body, the bottom of the sliding bearing body is slidably mounted in a mounting frame, both sides of the sliding bearing body are provided with an adapter mechanism for locking the position of the sliding bearing body, a mounting plate is provided below the mounting frame, and an adapter mechanism for adjusting the height of the sliding bearing body is provided between the mounting frame and the mounting plate. The utility model uses the setting of the adapter mechanism, and the pneumatic cylinder drives the mounting frame to rise and fall, and the mounting frame drives the sliding bearing to rise and fall to adjust its height. During the process of the mounting frame rising and falling, the movable rod is driven to rise and fall in the outer sleeve, which can limit the mounting frame to avoid the displacement of the mounting frame. By lifting and lowering the sliding bearing, the sliding bearing can meet the needs of motors of different heights, thereby improving the matching degree between the sliding bearing and the motor and expanding the matching between the sliding bearing and the motor.

[0004] Although the above-mentioned sliding bearings have the function of height adjustment and can be adapted to different motors, their heat dissipation performance has not been enhanced. The sliding bearings will generate heat due to friction under long-term high-load operation. The accumulation of heat will cause the sliding bearings to expand thermally, which in turn causes friction among the components inside the bearings, resulting in the bearings being stuck. If the sliding bearings are not cooled in a timely and effective manner, they may even cause local deformation of the bearings at high temperatures, reducing the service life of the sliding bearings. Therefore, in response to the above problems, an oil-gas mixed lubrication and efficient cooling sliding bearing and a cooling method thereof are proposed. Summary of the Invention

[0027] 1. The present invention achieves efficient cooling of the sliding bearing through the structural design of the circulating cooling mechanism. This solves the problem that although existing sliding bearings have a height adjustment function and can adapt to different motors, their heat dissipation performance has not been enhanced. When sliding bearings work under long-term high loads, they will generate heat due to friction. Heat accumulation will cause thermal expansion of the sliding bearings, which in turn causes friction between various components inside the bearings, resulting in bearing rotation jamming. If the sliding bearings are not cooled in time, they may even cause local deformation of the bearings at high temperatures. This improves the service life of the sliding bearings and enables them to operate stably for a long time under high-load conditions without overheating.

[0028] 2. The present invention realizes the function of accelerating the cooling of the cooling oil through the structural design of the circulating cooling mechanism. This solves the problem that if there is no component that can accelerate the rapid cooling of the cooling oil, the temperature of the cooling oil will easily rise after a long period of circulating cooling, resulting in a decrease in the subsequent cooling effect and an inability to effectively achieve the cooling effect. The cooling effect is improved.

[0029] 3. The present invention realizes the function of filtering the cooling oil through the structural design of the circulating cooling mechanism, which solves the problem that if no components for filtering are provided, the cooling oil is easily mixed with impurities after a long period of circulating cooling. If the impurities in the cooling oil are not cleaned and filtered and the cooling process is directly performed, it is very easy to cause large wear of the sliding bearing, thereby improving the protection of the sliding bearing.
