The invention discloses a biaxial inertia exciter, and belongs to the technical field of mechanical vibration devices and manufacturing. The exciter comprises a rotary power source, a circular gear transmission mechanism and at least two same eccentric mechanisms, each eccentric mechanism comprises an eccentric mass block rotating around a rotating shaft, the rotating powre source drives the eccentric mass blocks to rotate around the rotating shafts through the circular gear transmission mechanism, the rotating speeds of the eccentric mass blocks are consistent, component force of resultant force of eccentric force generated by the eccentric mass blocks on the plane is zero, the circular gear transmission mechanism is replaced with a non-circular gear mechanism, according to the biaxial inertia exciter adopting the non-circular gear mechanism, according to the difference orders of a driven non-circular gear section curve, the non-symmetric inertia exciter and the reinforcing type inertia exciter can be achieved.
Description
technical field [0001] The invention relates to a vibrator, especially a modified inertial vibrator capable of outputting asymmetric inertial vibrating force, which is a power source of vibrating machinery and belongs to the technical field of mechanical vibrating devices and manufacturing. Background technique [0002] With the development of social economy and technology, in the fields of scientific research, infrastructure construction, industrial production and industrial robots, it is often necessary for the excited object to obtain an exciting force of a certain form, size or frequency. In actual production applications, the vibration of most vibrating machinery The source is provided by an exciter. The exciter can also be used as an exciting part to form a vibrating machine to realize the conveying, screening, compacting, forming and tamping of soil and gravel of materials or objects. Vibrator can be divided into inertial type, electric type, electromagnetic type, el...
