s2, when the middle friction disc (2) swings towards the oil storage tank (9), the balls (19) are in contact with the middle friction disc (2) and are pressed under stress; the extrusion frame (18), the extrusion rod (17) and the extrusion plate (16) move synchronously, one side of the extrusion bag (13) is extruded, so that lubricating oil in the extrusion bag is extruded out and is ejected towards the friction disc through the nozzle (15);
s3, when the middle friction disc (2) is far away from the oil storage tank (9), lubricating oil in the oil storage chamber (11) is sucked into the extrusion bag (13) through the oil inlet pipe (14) under the action of negative pressure in the extrusion bag (13);
s4, the lubricating oil is sprayed out in a small amount and multiple times in a dispersing way to act on the friction disc;
and S5, when the oil storage chamber (11) is lack of oil, oil is fed through the lubricating oil inlet pipe (27).
