Large-tonnage vibration exciter

Abstract

The invention discloses a large-tonnage vibration exciter, which comprises a box body, a rotating shaft, an eccentric gear, a driving gear and a lubricating oil circulating system, at least one group of bearing seats are arranged on the box body, two ends of the rotating shaft are respectively arranged on the bearing seats through bearings, the eccentric gear and the driving gear are respectively connected to the rotating shaft, and the eccentric gear is meshed with the driving gear; the eccentric gear is a split type eccentric wheel, the lubricating oil circulating system comprises an oil spraying hole, an oil return hole, an oil suction pipe, an oil outlet pipe, an oil baffle plate and a gear pump which are arranged on the box body, the gear pump is used for providing power for the lubricating oil circulating system, and the two ends of the oil suction pipe are communicated with the oil return hole and the gear pump respectively. The two ends of the oil outlet pipe are communicated with the oil spraying holes and the gear pump respectively, the oil spraying holes correspond to the bearings in a one-to-one mode, the oil baffle plate is arranged below the eccentric gear and the driving gear, an oil storage space is formed between the oil baffle plate and a bottom plate of the box body, and an oil return hole is formed in the bottom plate. The device has the technical effects that the manufacturing cost is reduced, maintenance and replacement are convenient, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, in particular, the invention relates to a large-tonnage vibration exciter. Background technique [0002] For the exciter, its main structure includes a motor (motor drive or hydraulic drive), a box, a drive wheel, an eccentric wheel, a driving shaft and a driven shaft to provide power. For the eccentric body rotating vibrator, the eccentric wheel is driven to rotate by the driving wheel. Generally, a pair of eccentric wheels is used. When the eccentric wheels are reversed, the horizontal centrifugal forces generated cancel each other out, and the same centrifugal force is generated vertically, thereby superimposing a larger impact force. As the eccentric wheels rotate, up and down vibrations are generated. The eccentric wheel structure includes a gear, an eccentric body and a rotating shaft. In the prior art, the gear and the eccentric body are integrally cast, and the gear and ...
