HIGH-SPEED BEARING CAPABLE OF SELF-ACTIVATED SPRAYING OF OIL MIST LUBRICATION, LUBRICATING METHOD, AND APPLICATION
Document Type and Number:
WIPO Patent Application WO/2021/036657
Kind Code:
A1
Abstract:
A high-speed bearing capable of self-activated spraying of oil mist lubrication, a lubricating method, and an application for motors. The high-speed bearing comprises an outer annular sleeve (8) and an inner annular member (4). Two ends of the outer annular sleeve (8) are connected to the inner annular member (4) via non-contact type sealing components (3). An oil storage space (10) and a retaining frame (6) are provided between the outer annular sleeve (8) and the inner annular member (4). The oil storage space (10) and the retaining frame (6) are located between two sealing components (3). A rolling member (2) is provided on the retaining frame (6). The oil storage space (10) corresponds to a side of the retaining frame (2) provided with the rolling member (2). The bearing has advantages of structural simplicity, a long service life under high-speed and ultra high-speed operations, simple construction of a lubrication system, low lubricant consumption, an eliminated need of compressed air, etc. Disposing the bearing at two sides of a motor rotor improves the rotation speed of the motor without using a complex lubrication system or consuming a large amount of lubricant.
