Vibratory compactor and compact exciter assembly usable therewith

摘要

A method of assembling an exciter assembly for a compaction machine includes mounting a torque transfer element and a bearing on an exciter shaft. A fixed eccentric weight is mounted on the exciter shaft. First and second free swinging eccentric weights are mounted on the exciter shaft adjacent respective ends of the fixed eccentric weight so as to be rotatable a limited amount relative to the exciter shaft. The first and second free swinging eccentric weights are restrained from substantial axial movement along the exciter shaft solely by being sandwiched the first and second free swinging eccentric weights between the respective ends of the fixed eccentric weight and operative components of the exciter assembly. All of the mounting steps are performed without the use of any mounting hardware.
