AI Technical Summary
Existing self-aligning roller bearings suffer from poor lubricant flow under low-speed, heavy-load conditions, making it difficult to fully wet the clearance between the roller outer wall and the cage pocket. This results in the inability to continuously and stably form an effective lubricating oil film, leading to severe dry friction and affecting the bearing's service life and reliability.
The self-lubricating self-aligning roller cage is adopted. By setting a chemically bonded polymer skeleton in the oil storage area of the cage column, and setting three-dimensional interconnected micro-nano pores inside the polymer skeleton, the lubricating oil is adsorbed and locked by capillary action to form a stable lubricating oil film. Combined with the lightweight design of aluminum alloy, adaptive oil supply is achieved.
Under low-speed, heavy-load conditions, a stable lubricating oil film is continuously formed, avoiding dry friction, improving the bearing's operational reliability and lifespan, while reducing manufacturing costs and rotational inertia, and enhancing operational stability.
