Problems solved by technology

Since the chain has a fixed pitch, and the vibrating sprocket and the eccentric shaft are usually connected by a key, it can only be adjusted in steps to make the phase difference of the two shafts roughly meet the design requirements, and it is not convenient to fine-tune the phase angle

Abstract

The invention relates to the technical field of chain transmission, in particular to a chain transmission device of a sound wave vibration exciter. The chain transmission device of the sound wave vibration exciter comprises a chain, and a driving chain wheel, a vibration chain wheel A, a chain distance adjusting device, a vibration chain wheel B, a driven chain wheel, a tensioning device and a mounting bottom plate which are arranged in sequence; through the chain distance adjusting device, a second adjusting chain wheel can be moved and adjusted in the direction perpendicular to the center connecting line of vibration wheels, and then fine adjustment of the phase difference of two vibrating shafts is achieved; and the whole chain is tensioned through the tensioning device, and tremble generated during high-speed transmission can be eliminated.

Description

technical field [0001] The invention relates to the technical field of chain transmission, in particular to a chain transmission device for an acoustic wave exciter. Background technique [0002] The sonic power head drilling rig uses the rotation of the drill bit and high-frequency axial vibration to complete the drilling operation, which can liquefy the soil during drilling and reduce the disturbance to the surrounding geology. When mechanical excitation is used, the exciter consists of two sets of eccentric shafts with the same form, size, weight and eccentricity. In terms of the drive technology of the eccentric shaft, there are two ways of double-drive synchronization and single-drive synchronization. Finally, the rotation directions of the two eccentric shafts are opposite and the rotational speeds are the same. The centrifugal forces on the eccentric shafts cancel each other out in the horizontal direction, and the component forces in the vertical direction are super...
