Abstract
The utility model discloses a lubricating oil sealing structure for bearings of a of vibration exciter spindle. The sealing structure comprises the vibration exciter spindle supported by the bearings and a bearing block for arranging and supporting the bearings. Each bearing is provided with a thin oil lubricating structure and a labyrinth sealing structure. Each thin oil lubricating structure comprises a lubricating cavity formed by the annular bearing block and bearing caps on two sides. Each labyrinth sealing structure is formed by embedding the bearing caps on the two sides and labyrinth caps outside the bearing caps. The opposite surfaces of the bearing caps and the labyrinth caps have embedded 'E'-shaped structures. By the structure, thin oil cannot outflow when a vibration exciter is stopped, and the bearing caps and the labyrinth caps naturally form a pressure curtain when the vibration exciter is started, so that the lubrication of the bearings is ensured, and the service life of each bearing is greatly prolonged; the bearings are lubricated by the thin oil, so that the workload of injecting lubricating grease is reduced, and the oil is only required to be periodically replaced after a certain time to save the cost; and the thin oil also can be used for cleaning the interior of the vibration exciter, so that the service life of the vibration exciter is prolonged.
