Abstract

A continuous adjustable eccentric vibration exciter comprises a disc-shaped eccentric base body, the eccentric base body is installed on a rotating shaft, a plurality of pairs of threaded holes are formed in the circumferential face of the eccentric base body in the radial direction, an eccentric mass rod is rotationally installed in each threaded hole in a threaded connection mode, and the outer end of each eccentric mass rod is connected with a nut. Each eccentric mass rod is sleeved with a compressed spring, the inward end of each compressed spring abuts against the circumferential face of the eccentric base body, and the outward end of each compressed spring abuts against the corresponding nut. The invention aims to provide the continuously adjustable eccentric vibration exciter which can continuously adjust the eccentric distance, can generate continuously adjustable exciting force so as to obtain continuously adjustable exciting force amplitude, can be applied to vibration tests in the mechanical fields of vehicles, machine tools and the like, and particularly can be used for carrying out vibration response test analysis, fatigue tests and vibration aging treatment on parts.

Description

Technical field [0001] The present invention relates to a continuous adjustable eccentric excivatator. Background technique [0002] The vibration exciter is an apparatus attached to some mechanical and devices to produce an excitation, which is an important part of mechanical vibration. The excitation can enable the excitable to obtain a certain form and size of the vibration, thereby vibrating and intensity testing objects, or calibrating the vibration test instrument and sensor. The excitation can also be operated as an exciting member to achieve the transport, screening, compact, molding, and soil sand stone of the material or the tamper. According to the excitation type, the excitator is divided into inertial, electric, electromagnetic, electro-hydraulic, pneumatic and hydraulic and other types. The excitation can generate unidirectional or multi-directional, harmonious or non-simple exciting exciting. [0003] The inertial inertial exciter is also mechanical excitation, whi...
