Изобретение относитс к способам уменьшени вибраций при конструировании пневмоударников .This invention relates to methods for reducing vibrations in the design of an air hammer.
Известен способ управлени движением поршн пневмоударника путем регулировани подачи сжатого воздуха в камеры пр мого и обратного хода.A known method of controlling the movement of a piston of an air hammer by adjusting the supply of compressed air to the forward and reverse chambers.
Цель изобретени - умеьшение вибрации пневмоударника.The purpose of the invention is the reduction of the vibration of an air hammer.
Это достигаетс тем, что сохран ют давление сжатого воздуха в камере пр мого хода после удара поршн по инструменту по крайней мере до момента их повторного соударени .This is achieved by maintaining the pressure of compressed air in the forward stroke chamber after the piston has hit the tool at least until they are re-impacted.
В конце обратного хода поршн пневмоударника происходит выпуск сжатого воздуха из камеры обратного хода и впуск сжатого воздуха в камеру пр мого хода. Происходит перемещение поршн , который наносит удар по хвостовику инструмента. После удара давление сжатого воздуха в камере обратногоAt the end of the reverse stroke of the pneumatic hammer piston, the compressed air is released from the reverse chamber and the compressed air is introduced into the forward stroke chamber. The piston moves, which strikes the tool shank. After the impact, the pressure of compressed air in the chamber
хода сохран ют, по крайней мере, до тех пор, пока не произойдет повторного соударени инструмента, который отходит назад после удара по забою под действием силы реакции,the strokes are maintained, at least until a re-impact of the tool occurs, which retreats after the impact on the face of the face under the action of the reaction force,
и поршн . При этом соударении сжатым воздухом , наход щимс в камере пр мого хода, гаситс реактивный ударный импульс.and piston. This collision with compressed air, which is in the forward stroke chamber, extinguishes the reactive shock pulse.
Таким образом, пневмоударник предохран етс от вибрации, вызываемой реактивнымиIn this way, the air hammer is prevented from vibrating due to reactive
ударными импульсами.shock pulses.
