Transmission system lubrication cooling structure and cooling method

The invention discloses a transmission system lubrication cooling structure and a cooling method thereof. By arranging a lubrication liquid inlet main pipeline on one side of a main transmission shaftand forming a water inlet in the inner wall of a sliding bearing, when the main transmission system rotates, a PLC simultaneously issues instructions to open a valve on the lubrication liquid inlet main pipeline, and the pure water used for lubrication and cooling can continuously flow into a friction surface between the sliding bearing and a main transmission partition sleeve through a spiral diversion groove in the end of the sliding bearing; and the purposes of lubrication and friction temperature reducing are achieved, because rotation friction coefficient is decreased, the noise of the whole transmission system is obviously reduced. The transmission system lubrication cooling structure can effectively improve the service life and stability of the parts through lubrication and coolingon the parts with relativ
