Abstract
Our vibratory roller studies have been approaching maturity, but there is still a big gap compared with foreign countries, mainly reflected in: product model is not full, heavy and the number and variety of the production of ultra heavy rollers is still small, the lack of special compaction equipment, comprehensive technical and economic indicators and automatic control is still lower than the international advanced level. This paper intends to study the relevant parameters and structure of vibratory wheel, which can achieve the required working state, to narrow the gap with foreign research.
Based on the theoretical analysis and calculation, the design of vibration of frame and working device of wheel of YZ18 vibratory roller, determine the basic parameters, the vibration wheel is the main part of the design, the design content including the design of vibrating wheel vibration shaft and a vibration exciter, supporting structure, bearing vibration calculation and the selection, calculation and check of shock absorber. The structure vibration shaft with eccentric block used in the vibration structure, vibration form can produce double amplitude, damping system with rubber shock absorber.
Key words: vibratory roller,the front frame,vibrating drum,eccentric block, vibration force, Shock absorber.
