Problems solved by technology

Due to the constraints of the process technology and the performance of bearing accessories, most of the similar products are double-layer and three-stage screening, and the vibration exciter generally adopts the eccentric shaft excitation structure (see the attached picture). The structure of the vibration exciter has the following defects: 1. The exciting force is generated by the eccentric rotation of the shaft. The weight of the eccentric shaft is relatively large, and the heaviest can reach more than 500kg. It is difficult to disassemble and maintain: 2. The moment of inertia of the eccentric shaft is large, the required motor power is large, and it is difficult to start the screen machine; 3. The exciting force Concentrated in the middle of the two siev

Abstract

The invention discloses a double-bearing self-adjusting aligning web plate type round vibrating screen formed by connecting with a belt wheel device on a common motor. The belt wheel device is connected with an intermediate driving device which is connected with an eccentric device through a flexible coupler; the eccentric device is connected with a bearing chamber through a universal driving shaft; the belt wheel device consists of a larger belt wheel, a small belt wheel and a V-shaped belt; the eccentric device consists of an aligning bearing, an eccentric block and a shaft head flange; a web plate type vibration generator is arranged below the bearing chamber; and the lower end of the eccentric device is connected with the bottom of the web plate type vibration generator through the screen edge. The defects of an eccentric shaft structure can be avoided by using the structure.

Description

Technical field: [0001] The invention relates to a vibrating screen, in particular to a 3YKR2460 circular vibrating screen with a double-bearing self-adjusting centering web type excitation source, which belongs to the field of mechanical equipment. Background technique: [0002] As a kind of material classification equipment, circular vibrating screen is mainly used in smelting, mining, water conservancy, coal mining, chemical industry and other industries. Due to the constraints of the process technology and the performance of bearing accessories, most of the similar products are double-layer and three-stage screening, and the vibration exciter generally adopts the eccentric shaft excitation structure (see the attached picture). The structure of the vibration exciter has the following defects: 1. The exciting force is generated by the eccentric rotation of the shaft. The weight of the eccentric shaft is relatively large, and the heaviest can reach more than 500kg. It is di...
