Novel thin oil lubrication flange type vibration exciter

Abstract

The invention discloses a thin oil lubrication flange type vibration exciter. A balancing weight is fixed to an eccentric block through a bolt, a shaft penetrates center holes of all parts including the eccentric block, a labyrinth cover, a through hole cover, a shaft sleeve, an oil slinger, oil stirring teeth, a bearing chamber, bearings, an oil seal, an O-shaped rubber ring and a round nut, shaft heads at the two ends of the shaft are matched with couplings, the bearing chamber is in screwed joint to a vibration screen side plate through a flange, the bearings and the oil stirring teeth arearranged inside the bearing chamber, the bearings are located at the two ends of the oil stirring teeth, a through hole cover is in screw joint with the two sides of the bearing chamber, the labyrinthcover is arranged on the outer side of the through hole cover, the through hole cover is matched with the labyrinth cover to generate a labyrinth groove, the middle of the labyrinth cover and the shaft sleeve is sealed through the oil seal, the middle of the shaft sleeve and the shaft is sealed through the O-shaped rubber ring, the eccentric block is tightly arranged on the outer side of the labyrinth cover to be pressed tightly through the round nut. The novel thin oil lubrication flange type vibration exciter is small in size, compact in structure, even in lubrication, good in cooling effect and convenient to install and maintain, long-time stable running of the vibration exciter is guaranteed, the service life of the vibration exciter can be greatly prolonged, the working efficiency ofthe vibration exciter is greatly improved.

Description

1. Technical field: [0001] The invention relates to a vibration exciter, in particular to a thin oil lubricated flange type vibration exciter. 2. Background technology: [0002] In recent years, with the wide application of vibration equipment in coal, metallurgy, mining, electric power and other industries, as the vibration source of vibration equipment, the exciter is the core component of the vibration equipment, and the performance of the exciter directly affects the service life of the vibrating screen . The vibration exciter in the prior art adopts the grease lubrication method. During the use of the vibration exciter, phenomena such as bearing lockup and high bearing temperature are prone to occur. The reason is that the sealing performance is not good, dust is easy to float in, and the air permeability is not good. And the use of grease lubrication is prone to dryness of lubricating grease, which seriously affects the service life of the exciter, and the service lif...

AI Technical Summary

Problems solved by technology

The vibration exciter in the prior art adopts the grease lubrication method. During the use of the vibration exciter, the phenomenon of bearing lockup and high bearing temperature is prone to occur. The reason is that the sealing performance is not good, dust is easy to float in, and the air permeability is not good. And the use of grease lubrication is prone to grease dryness, which seriously affects the service life of the exciter, and the service life of the exciter will directly affect the normal operation of the vibration equipment
