Description

Technical Field

[0001] The utility model relates to an assembled vibration exciter structure and a vibrating roller, belonging to the technical field of vibrating rollers. Background Art

[0002] The exciter is the force source for the vibration of the vibratory roller. The exciter on the existing vibratory roller mainly includes two fixed eccentric blocks, one movable eccentric block, a limit pin and a vibrating shaft. The two fixed eccentric blocks are welded on the vibrating shaft, the movable eccentric block is located between the two fixed eccentric blocks, and the limit pin is welded and installed between the two fixed eccentric blocks. The centrifugal force generated by the eccentric blocks when the vibrating shaft rotates at high speed is the exciting force of the vibrating roller. By changing the rotation direction of the vibrating shaft, the phase difference between the movable eccentric block and the fixed eccentric block changes under the positioning of the limit pin, generating two different static eccentric distances, thereby realizing the switching of the large and small amplitudes of the vibrating wheel. This type of exciter has many parts, is time-consuming and labor-intensive, and the reliability of the welded structure is not high, which affects the service life of the parts.
