Multistage eccentric block vibrating motor

Abstract

The invention provides a multistage eccentric block vibrating motor which relates to a vibrating motor with special inertia excitation capability and belongs to the technical field of vibrating utilization engineering. The vibrating motor comprises a stator, a rotor and multistage eccentric block assemblies; the stator consists of a stator core, a stator winding, a bearing base and a machine casing; the rotor consists of a rotor shaft, a rotor core and a rotor winding; the rotor winding is assembled on the rotor core; the rotor core is sleeved on the rotor shaft; the rotor shaft is arranged in a bearing base through a bearing A; both sides of the bearing base are respectively provided with an inner press cover and an outer press cover; both ends of the rotor shaft are respectively provided with the multistage eccentric block assemblies; the multistage eccentric block assembly is formed by connecting a plurality of eccentric blocks in series through an eccentric block shaft and is symmetrically distributed at the right end and the left end of a first-stage shaft (i.e. rotor shaft); and the stage number K is greater than or equal to 2. The multistage eccentric block assembly comprises a main eccentric block, an auxiliary eccentric block, a multistage eccentric block, a multistage eccentric block shaft and a multistage bearing, wherein the main eccentric block and the auxiliary eccentric block are fixedly arranged at the ends of the rotor shaft.

Description

technical field [0001] The invention relates to a multi-stage partial block vibration motor, which relates to a vibration motor with special inertial vibration excitation capability, and belongs to the technical field of vibration utilization engineering. Background technique [0002] A vibration motor is an excitation device that uses the principle of vibration to drive a vibrating machine to work. Both an ordinary vibration motor and an ordinary motor have a stator and rotor structure, but they are very different in structure, principle, and function. [0003] Ordinary motors are three-phase asynchronous motors, which are AC motors that generate electromagnetic torque through the interaction between the air-gap rotating magnetic field and the induced current of the rotor windings, thereby realizing electromechanical energy conversion. The motor should avoid vibration as much as possible during operation to ensure the system normal and stable operation. [0004] Ordinary v...

Problems solved by technology

[0007] In many cases, vibrating machinery requires the system to have a wide power spectrum curve and some irregular performance of the motion track to complete some special operations, such as the low penetration rate of the vibrating screen machine, the screen stuck, etc., the vibration Ordinary vibrating motors are almost powerless to solve the problems of unrefinement and easy agglomeration of fine powder in the mill.
