Vibratory roller stepless frequency conversion amplitude modulation exciter

Abstract

The invention relates to a stepless frequency conversion AM (amplitude modulation) vibration exciter of a vibratory roller. The vibration exciter comprises two support plates (2) which are vertically arranged in parallel, wherein stopping blocks (3) are respectively connected between the tops and the bottoms of the two support plates; an eccentric shaft (1) is connected between the two support plates (2) in a penetrating manner; eccentric blocks are arranged between the eccentric shaft (2) and the spacing blocks (3), and elastic elements are connected between the eccentric blocks and the spacing blocks. The stepless frequency conversion AM (amplitude modulation) vibration exciter of the vibratory roller, disclosed by the invention, has the characteristics of stepless frequency conversion and amplitude modulation, small vibration exciting torque, good manufacturability, zero impact, good consistency, reliable operation, convenient maintenance, low cost and the like.

Description

technical field [0001] The invention relates to an exciter, in particular to an exciter capable of adjusting the vibration frequency used on a vibratory road roller, and belongs to the technical field of vibratory road roller equipment. Background technique [0002] At present, the vibration of the vibratory roller is realized by the exciter in the vibrating wheel. The vibration generated by the exciter makes the vibrating wheel of the vibratory roller exert a compacting force on the ground, thereby improving the compaction efficiency and compaction of the vibratory roller. quality; [0003] The exciter of the traditional road roller is composed of fixed eccentric block, movable eccentric block and eccentric shaft. The size vibration of the steel wheel is realized through the clockwise and counterclockwise rotation of the eccentric block group composed of the fixed eccentric block and the movable eccentric block; The block vibrator is widely used in current vibratory roller...

Problems solved by technology

[0003] The exciter of the traditional road roller is composed of fixed eccentric block, movable eccentric block and eccentric shaft. The size vibration of the steel wheel is realized through the clockwise and counterclockwise rotation of the eccentric block group composed of the fixed eccentric block and the movable eccentric block; The block vibrator is widely used in current vibratory rollers because of its simple structure and low cost, but its biggest disadvantage is that this type of vibrator can only achieve two amplitudes, namely large vibration and small vibration, and the amplitude is single. In addition, in the process of starting and stopping vibration, a great impact force is generated on the vibration bearing, which reduces the life of the bearing, and high precision is required in manufacturing, and the manufacturing cost increases accordingly. The construction party brings a lot of inconvenience
