Oil-free direct-driven vibrating screen

Abstract

The invention belongs to the technical field of screening and particularly relates to an oil-free direct-driven vibrating screen and an installation method thereof. By means of the oil-free direct-driven vibrating screen and the installation method thereof, the unreasonable design and other technical problems in the prior art are solved. The oil-free direct-driven vibrating screen comprises a slantly-arranged vibrating screen frame fixed on an elastic supporting mechanism, the upper portions of the two sides of the vibrating screen frame are provided with at least one vibrating motor correspondingly, one vibrating motor installed to the upper portion of one side of the vibrating screen frame and one vibrating motor installed to the upper portion of the other side of the vibrating screen frame are oppositely arranged, and an output shaft of each vibrating motor is provided with an eccentric block correspondingly and a connection mechanism connected to the output shafts of oppositely-arranged two vibrating motors and arranged above the width direction of the vibrating screen frame horizontally. The oil-free direct-driven vibrating screen has the advantages of being simple in operation and maintenance and more compact in structure.

Description

Technical field [0001] The invention belongs to the technical field of screening, and particularly relates to an oil-free direct drive vibrating screen and an installation method thereof. Background technique [0002] Traditional vibrating screens are mainly driven by several drive motors, generally 1-2, which are driven by belts with pulleys installed at one end of the bearing housing to reduce speed. The other end of the bearing housing is connected to the vibrating screen frame through an elastic coupling. The eccentric vibration component on the side is connected, and the eccentric vibration component is rigidly connected to the eccentric component installed on the other side of the screen frame through the main shaft of the screen body. When the drive motor rotates, it drives the two sets of eccentric vibration components to rotate at the same time to obtain an eccentric driving force. Since the entire screen body is supported by four support springs, the entire screen body ...

AI Technical Summary

Problems solved by technology

[0004] 1. Since the eccentric component needs to pass through the coupling, then pass through the pulley on the bearing seat, and then connect to the drive motor, the overall vibrating screen has large dimensions and heavy weight, which not only increases the manufacturing cost, increases the packaging and transportation cost, but also affects the production workshop. Installation space is limited

[0005] 2. The drive motor, pulley and bearing group can be referred to as the drive unit for short. Since the drive unit is connected to the eccentric component through an elastic coupling, the eccentric component is rigidly connected to the screen body, and the screen body performs an eccentric reciprocating motion, so the drive unit does not It moves together with the screen body, but needs to be rigidly connected to the ground, so additional cement foundation and supporting steel platform are required, which also increases the manufacturing and installation cost of the equipment

[0008] 5. The grease lubrication of the bearing group also needs regular inspection and refueling
