The utility model discloses a follow-up shaft head sealing oil baffle device. The oil seal comprises an oil seal outer ring and an oil seal inner ring, wherein the outer edge of the oil seal outer ring is connected with a bearing seat of the rotating equipment in a sealed mode, an annular groove matched with the oil seal inner ring is formed in the inner wall of a center hole of the oil seal outerring, a rotating shaft of the rotating equipment is sleeved with the oil seal inner ring, and the periphery of the oil seal inner ring is inserted into the annular groove in the inner wall of the center hole of the oil seal outer ring. The split type oil seal piece composed of the oil seal outer ring and the oil seal inner ring is adopted, and when the rotating shaft vibrates in the radial direction, the oil seal inner ring can vibrate along with the rotating shaft and is always coaxial with the rotating shaft, so that the acting force between the oil seal inner ring and the rotating shaft isreduced, and the abrasion speed is reduced. Compared with a traditional sealing oil baffle device, the sealing oil baffle device is good in sealing effect, long in service life, capable of effectively preventing oil leakage of rotating equipment and reducing resource waste and field environmental pollution, and particularly suitable for equipment with large vibration amplitude of the rotating shaft.
