Technical Field

The invention relates to the field of vibration exciters, in particular to a multi-axis circular vibration exciter with a synchronizing function.

Background

Known vibrating devices require exciters for the excitation of the device, which are divided into single-axis circular exciters and two-axis linear exciters,

the known vibration exciter is mainly a single-shaft circular vibration exciter, and the circular vibration exciter realizes a circular motion track through one shaft. And the box body of the double-shaft linear vibration exciter is internally provided with two shafts, each shaft is provided with a gear, and the two gears are meshed, so that the linear motion trail of the double shafts in opposite motion is realized. The linear vibration exciter cannot realize the rounding of the running track of the vibration equipment, so the use application is limited, and although the single-shaft circular vibration exciter can realize the circular motion track, the single-shaft circular vibration exciter is limited by the number of the bearings, the number of the unit bearings determines the output torque limit of the vibration exciter, so the circular motion track cannot be applied to the ultra-large vibration equipment. In addition, in the prior art, grease lubrication is often adopted for single-shaft circular exciters, and even if part of the single-shaft circular exciters is lubricated by thin oil, heavy equipment cannot be driven by the single-shaft exciters due to the limitation of the number of bearings, so that the size of the vibration device cannot be increased.

Often through amalgamating together two unipolar circular vibration exciters among the prior art, realize the vibration exciter of the circular motion orbit of biax, but this kind of vibration exciter itself does not have synchronizer, in order to realize the biax is synchronous, often realize the synchronization of biax through the dynamic characteristic of deciding the focus certainly, when vibration equipment needs bigger excitation device, just there is the multiunit, multiseriate biax or the installation of multiaxis vibration exciter module, because current biax circular vibration exciter is that two unipolar circular vibration exciters are amalgamated together, every vibration exciter module does not contain synchronizer, the synchronous problem of multiunit multiseriate modularization vibration exciter makes the circular vibration exciter of this type can't use. In order to utilize the characteristic that the motion trail of a circular vibration exciter is circular and simultaneously take into account the high requirement of large-scale vibration equipment on driving force, the technical staff in the field needs to solve the problem of how to realize the synchronization of two-axis or multi-axis driving of the conventional vibration exciter and also take into account the high requirement of the large-scale vibration equipment on the driving force.
