Three-joint three-phase asynchronous flame proof vibrating motor

Abstract

The invention relates to a three-joint three-phase asynchronous flame proof vibrating motor that consists of two vibrators (2) and a three-phase asynchronous flame proof motor. The three-phase asynchronous flame proof motor consists of a base (4), and a rotor (19) and a stator (18) which are in the middle of the base. An inner seat cover (17) and a bearing which plays a role of supporting are arranged between the stator and a bearing support (13). Two ends of the base are respectively provided with a vibrator (2). Each vibrator is internally provided with two eccentric blocks (9) which are in key connection with a rotor spindle; the right side and left side of each eccentric block are respectively provided with a bearing for supporting the vibrator. Due to the adoption of the novel structure, the motor solves the technical difficulties of the prior art, can not only realize self synchronization shock excitation after being directly mounted on a vibrating machine, but also conveniently realize a plurality of purposes of light weight, long span, low power, large shock excitation force, flame proofing and the like, and can be widely applied to relevant self synchronization vibrating screens of a plurality of industries.

Description

technical field [0001] The present invention relates to the power equipment of vibrating machinery, especially one that can be used in the fields of petroleum and natural gas drilling, mineral processing, coal preparation, chemical industry, medicine, food, non-ferrous metals, water conservancy and hydropower engineering, underground space engineering, urban construction engineering and transmission, etc., as Three-joint three-phase asynchronous flameproof vibration motor for mud treatment, muddy water treatment, material screening and transmission. Background technique [0002] With the development of self-synchronization technology, various types of self-synchronization vibrating machines basically use the vibration excitation motor to directly participate in the vibration, which puts forward more and more stringent requirements on the quality and technical conditions of the vibration excitation motor. , especially while requiring a large excitation force, the lighter the ...

Problems solved by technology

However, the existing vibrating motor is restricted by various factors due to the "power-to-mass ratio" (that is, the ratio of the force to its own weight) between its exciting force and its own mass, so it is difficult to further improve it.
