High-frequency vibration exciter

The utility model discloses a high-frequency vibration exciter which comprises a machine frame and a shell, an eccentric shaft is rotationally connected in the shell through a first bearing and a second bearing, a first oil flinger and a second oil flinger which are arranged on the two sides of the first bearing are arranged on the eccentric shaft in a sleeved mode, and inclined bosses are arranged on the end faces, facing the first bearing, of the first oil flinger and the second oil flinger. The vibration exciter can meet the requirements that oil is thrown upwards through the first oil flinger to infiltrate the first bearing, the second bearing is infiltrated through falling oil, the oil in the shell is circularly cooled through an external oil pump, the two bearings can be cooled during high-frequency work, and long-time use of the vibration exciter is guaranteed. And oil at the second oil flinger and the first bearing can be discharged, so that the oil leakage condition is avoided. 本实用新型公开了高频激振器，包括机架，包括外
