Title:
OIL LUBRICATION MECHANISM FOR FRONT BEARING OF WATER-COOLED MOTOR AND MOTOR DRIVING ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2020/125514
Kind Code:
A1
Abstract:
Disclosed by the present invention are an oil lubrication mechanism for a front bearing of a water-cooled motor and a motor driving assembly, which solve the problems of an existing front bearing of a water-cooled motor which employs grease lubrication heating up a severe amount and damage and short service life being caused due to grease being prone to flow out. The present oil lubrication mechanism for the front bearing of the water-cooled motor comprises a gear splatter oil storage structure arranged in a gearbox or a reduction gearbox and a bearing baffle oil storage structure arranged at the front end of the water-cooled motor; and lubricating oil is thrown into the gear splatter oil storage structure by a gear in the gearbox or the reduction gearbox during an operation process and is conveyed into the bearing baffle oil storage structure by means of an oil guide pipeline, so that the front bearing of the water-cooled motor is lubricated; and then the lubricating oil flows back into the gearbox or the reduction gearbox by way of an oil return pipeline. In the present invention, the lubricating oil splattered in the gearbox or the reduction gearbox is guided into the front bearing of the water-cooled motor, so that the front bearing of the water-cooled motor may be subjected to oil lubrication; the heating of the front bearing of the water-cooled motor is reduced, the service life of the front bearing of the water-cooled motor is prolonged, and the reliability of the motor is improved.
