A vibration exciter assembly structure and vibrating screen

Abstract

The invention provides a vibration exciter assembly structure and a vibration screen. The vibration exciter assembly structure comprises a power device and further comprises an external coupler, a spindle unit and a bearing structure. The external coupler is connected with the power device and the spindle unit. The bearing structure comprises two bearing sets which are symmetrically fixed to the two ends of the spindle unit respectively. Each bearing set comprises a bearing pedestal and two bearing pieces, wherein the two bearing pieces are installed in the bearing pedestal and connected to the spindle unit in a sleeving mode, and a balance weight is arranged on one side of each bearing piece and fixedly arranged on the spindle unit. The vibration screen comprises at least one vibration exciter assembly structure. The spindle unit can be provided with the two bearing sets. In each bearing set, the balance weights can be installed on one sides of the two bearing pieces, and the exciting force of the vibration exciter can be effectively improved. By means of the synchronizing wheel structure, the vibration screen can be provided with two or more vibration exciter assembly structures to further improve the exciting force, and the actual production requirement is met.

Description

technical field [0001] The invention belongs to the technical field of vibration equipment, and in particular relates to a vibration exciter assembly structure and a vibrating screen. Background technique [0002] Vibrator is a device attached to some machinery and equipment to generate excitation force. According to different excitation types, vibrator is divided into inertial type, electric type, electromagnetic type, electro-hydraulic type, pneumatic type and hydraulic type, etc. type. With the development of modern industry, vibration equipment is developing towards greater processing capacity and higher efficiency, which requires higher and higher requirements for exciters. The vibrating screen in the vibrating equipment uses an inertial vibrator. The inertial vibrator is mainly composed of a main shaft, two bearings and a pair of counterweights. For inertial excitation, the excitation force generated by the exciter can be increased by increasing the weight of the co...

AI Technical Summary

Problems solved by technology

[0004] In view of the above deficiencies in the prior art, the purpose of the present invention is to provide an overall bearing structure of the vibrator, aiming to solve the problem that only a pair of counterweights with limited weight can be installed due to the limited pressure that the main shaft and the bearing can bear. , resulting in the limited maximum excitation force generated by the exciter, which cannot meet the production needs
