Title:
DYNAMIC-PRESSURE SLIDING VANE BEARING ROTOR SYSTEM, MOTOR AND ELECTRIC APPLIANCE
Document Type and Number:
WIPO Patent Application WO/2021/169493
Kind Code:
A1
Abstract:
A dynamic-pressure sliding vane bearing rotor system and a motor comprising same. The rotor system comprises a rotating shaft (100). A dynamic-pressure sliding vane bearing is provided on the rotating shaft (100). The dynamic-pressure sliding vane bearing comprises at least two identical bearing units (501). The bearing units (501) are assembled to form a circular ring-shaped bearing body. The outer wall of the bearing body is provided with at least one annular groove in parallel with an end face. Elastomers (202) are provided in the groove. The dynamic-pressure sliding vane bearing is sleeved on the rotating shaft (100), and a predetermined gap is provided between the dynamic-pressure sliding vane bearing and the periphery of the rotating shaft (100). A fixing member is sleeved on the periphery of the dynamic-pressure sliding vane bearing and a gap exists therebetween. The rotor system is suitable for high speed working conditions, low in lubrication requirements, long in service life, and high in reliability.
