Lubricating device for vibration wheel of road roller

The utility model discloses a lubricating device of a vibrating drum of a road roller, when the road roller works, the phenomenon of burning bearing can often occur, and the bad lubrication is an important reason. A wheel body of the lubricating device is normally provided with a square lubricating groove, after the bottom part of the lubricating groove is filled with oil, when the wheel body rotates, the oil flows out of the lubricating bearing, but normally, and when the wheel body rotates to 90DEG, the oil is flowed out to cause bad bearing lubrication. A left and a right oil storage chambers are arranged at the bottom part of the lubricating groove by the utility model, oil flows from the two oil storage chambers with different rotation angles to lubricate the bearing, and when the wheel body rotates to 180DEG, the bearing can also be lubricated. The utility model is especially suitable for heavy type road rollers.
