Double-vibration exciter synchronous phase locking method and device

Abstract

The invention discloses a double-vibration exciter synchronous phase locking method and a device, wherein the device comprises two vibration exciters running in parallel in opposite directions, 2n (n is positive integer within 10) external gearing spur gears with the speed ratio of 1:1 are arranged to constitute a transmission pair, and the first spur gear of the transmission pair is connected with the main shaft of the first vibration exciter through a first elastic coupler and the last spur gear of the transmission gear is connected with the main shaft of the second vibration exciter through a second elastic coupler; a phase locking mechanism is mounted between the first spur gear or the last spur gear and the shaft of the gear, the phase locking mechanism can adjust a relative positionof the gear and the shaft in a rotating direction and locks the relative position. The device forcibly synchronizes the two vibration exciters by means of the gears, thereby eliminating the phase difference of the vibration exciters during operation, equalizing exciting force output and achieving steady-state excitation.

Description

technical field [0001] The present invention relates to vibration technology, and further refers to a synchronous phase-locking method and its device for outputting the centrifugal force generated by two vibrators only in one direction. Background technique [0002] Vibrators are widely used in the compaction of building components and structures during construction. When the two exciters run in opposite directions, in order to achieve the centrifugal force generated by the two exciters to output in one direction only, and to perform steady-state excitation, first of all, it is necessary to ensure that the two exciters should be synchronized. To do this, usually use the self-synchronization method of two motors. The self-synchronization method needs to meet the requirements of synchronization and the stability conditions in the corresponding synchronous state. These conditions include: the characteristics of the two motors should be the same or close, and the motor speed, e...

Problems solved by technology

There are many factors affected by the same method, the realization is difficult, and the manufacturing cost is correspondingly high

The self-synchronization of two exciters can achieve steady-state excitation, but under some specific conditions, if the two exciters are required to be installed regardless of the installation position, the output direction of the excitation force is required to be in the horizontal direction, while the vertical direction is Powerless output, self-synchronization alone cannot be achieved
