Lubricating oil circulating system for sliding bearing of high-speed motor

The utility model discloses a high-speed motor sliding bearing lubricating oil circulating system, which comprises a motor end cover, a sliding bearing and a motor casing, an oil inlet and an oil return port are arranged on the motor end cover, the oil return port is connected with an oil station oil tank through the surface of the motor casing, the oil inlet is connected with an outlet of an oil pump motor through a pipeline, and the oil return port is connected with an oil pump. An inlet of the oil pump motor is connected with an oil station oil tank, and a gap between the sliding bearing and the motor end cover and a gap between the sliding bearing and the machine shell are internal oil ways of the sliding bearing. The bearing is simple in structure, the temperature of the bearing can be effectively reduced, the bearing can reliably run for a long time, and the bearing can keep a relatively stable temperature in the high-speed running process, so that the bearing can reliably run for a long time. 本实用新型公开了一
