Throttle pneumatic impact mechanism equipped with afterburner idle-stroke chamber
Abstract
Pneumatic impact mechanisms are widely used in construction, mining and other economic sectors of a country. Such mechanisms are a base for a wide range of machines of various types and dimensions from hand-held tools to mounted piling hammers with impact energy up to 10 000 J. This paper is aimed at creation of pneumatic impact mechanism with the improved characteristics, including operation, energy use, weight and size which is especially important in space-limited working conditions. The research methods include development of computer mathematical model that can solve equations system and test a prototype model at the experimental stand. As a result of conducted research the pneumatic impact mechanism with the improved characteristics was developed. An engineering method for calculating throttle pneumatic impact mechanisms with a preset value of impact energy from 1 to 20 000 was investigated. This method allows creating percussive machines of a wide range of application.
