Title:
HEAT DISSIPATION METHOD FOR SLIDING BEARING OF ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2023/098019
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of electric motor heat dissipation, and particularly relates to a heat dissipation method based on a sliding bearing of an electric motor. The method comprises: machining a heat dissipation structure, and dissipating the heat of a bearing, wherein machining a heat dissipation structure comprises: providing an embedded heat-dissipation structure in a sliding bearing and/or mounting an external heat-dissipation structure in a bearing lubrication system of a generator; and dissipating the heat of a bearing comprises: using the embedded heat-dissipation structure to balance the internal temperature of the sliding bearing and/or using the external heat-dissipation structure to cooperate with the bearing lubrication system to externally conduct heat of the sliding bearing. In the technical solution, the embedded heat-dissipation structure and the external heat-dissipation structure are combined, such that the temperature gradient of a bearing shell body is gradually flattened, thermal deformation of a bearing is reduced, the thickness of an oil film is increased, and rapid cooling of the bearing under lubrication is also achieved. That is, an inner and outer double cooling means is used, thereby providing, to the maximum extent, effective and reliable heat dissipation conditions for a bearing under lubrication.
