Oil-tight vibration exciter and vibrating screen

Abstract

The invention discloses an oil-tight vibration exciter and a vibrating screen.The vibration exciter comprises a bearing assembly, a spindle assembly, wherein the bearing assemblycomprises a bearing member and a bearing seat; the spindle assembly is arranged between the bearing member and the bearing seat in a penetrating mode; the bearing seat is provided with an oil storage groove used for accommodating lubricating oil, and when in use, the height of the liquid level of the lubricating oil in the oil storage groove is lower than that of the joint of the bearing member and the bearing seat; and the vibrating screen comprises the oil-tightvibration exciter. According to the oil-free vibration exciter and the vibrating screen, theoil storage groove is formed in the bearing seat, the lubricating oil is stored in the oil storage groove, the height of the liquid level of the lubricating oil in the oil storage groove is lower than that of the joint of the bearing seat and the bearing member,the possibility of the lubricating oil leaking from the joint of the bearing seat and the bearing member or the joint of the bearing member and the spindle assembly is avoided, thus oil-tight character of the vibration exciter is realized, and the using amount of the lubricating oil is significantly saved

Description

technical field [0001] The invention relates to the technical field of mining vibration equipment, in particular to an oil-tight vibration exciter and a vibrating screen. Background technique [0002] The vibrating screen is an indispensable material classification equipment in various industries such as metallurgy, coal, mining, sand and gravel; it generates centrifugal force through the high-speed rotation of the eccentric block on the exciter to drive the vibrating screen box to make it on the set track. vibration. The high-speed rotation of the exciter is inseparable from good bearing lubrication, and good lubrication is the guarantee for the normal operation of the bearing. [0003] At present, the lubrication method of the vibrating screen is usually a grease lubrication method using a labyrinth seal or an oil seal. It is mainly used to inject lubricating oil into the exciter during the assembly of the vibrating screen exciter, or after the vibrating screen has been r...

AI Technical Summary

Problems solved by technology

In the actual work of the vibrating screen, there are gaps between the labyrinth rings, and the sealing method cannot completely seal the lubricating oil, causing the lubricating oil in the exciter to be continuously thrown out of the labyrinth rings, and the lubrication of the bearing is gradually weakened. If the oil is not timely, it will eventually cause the vibration exciter bearing to generate high temperature due to lack of oil, and its life will be shortened sharply, and more lubricating oil will be discharged, which will cause serious waste of lubricating oil
