The invention discloses a large-
tonnage vibrator, comprising a housing, a rotating shaft, an eccentric gear, a driving gear and a lubricating oil circulation
system, wherein at least one set of bearing seats is arranged on the housing, and the two ends of the rotating shaft are arranged on the bearing seats through bearings respectively, and the eccentric gear and the driving gear are connected to the rotating shaft respectively, and the eccentric gear and the driving gear are meshed; the eccentric gear is a split eccentric wheel, and the lubricating oil circulation
system comprises an oil spray hole, an oil return hole, an oil suction
pipe, an oil outlet
pipe, an oil baffle plate and a
gear pump arranged on the housing, and the
gear pump is used to provide power for the lubricating oil circulation
system, and the two ends of the oil suction
pipe are respectively connected with the oil return hole and the
gear pump, and the two ends of the oil outlet pipe are respectively connected with the oil spray hole and the gear pump, and the oil spray hole corresponds to the bearing one by one, and the oil baffle plate is arranged below the eccentric gear and the driving gear, and an
oil storage space is formed between the oil baffle plate and the bottom plate of the housing, and the bottom plate is provided with an oil return hole. The invention has the technical effects of reducing manufacturing cost, facilitating maintenance and replacement, and improving service life.
