    摘要： An impact element having the effect of elongating the pulse of force in impact tools and devices for chipping, hammering and similar operations, consisting of an element (8) which, for generating the striking motion, is axially moveable as a whole and comprises a driving mass (16) intended to be actuated by a propelling force, and a striking mass (17) located in front thereof relative to the direction of striking, which masses possess a limited freedom of axial movement with respect to each other in that they are coupled together by a stiff spring arrangement, e.g. cup washers (15), extremely hard plastics or gas cushions.

    摘要： An impact tool capable of improving durability of tool components and capable of reducing noise and vibration is provided. The impact tool includes a housing, a motor, a motion converting portion, an output portion, a power supply portion, a load detecting portion, and a control portion. The motor is disposed in the housing. The motion converting portion is configured to convert a rotating motion of the motor into a reciprocating motion. The output portion is configured to output the reciprocating motion of the motion converting portion as an impact force. The power supply portion is configured to supply a driving power to the motor. The load detecting portion is configured to detect a load imposed on the motor. The control portion is configured to control the power supply portion to increase the driving power supplied to the motor during a prescribed period when the load detected by the load detecting portion is larger than a prescribed value.

    摘要： The invention relates to a shield structure of a rock drilling apparatus for dampening noise, the rock drilling apparatus comprising a feed beam whose one end is a drilling end, whereby the drilling end of the feed beam comprises a first shield part mounted immovably relative to the feed beam, and a second shield part mounted movably relative to the feed beam. A tubular shield flexible at least in its longitudinal direction is mounted between the shield parts, the shield being tightly attached by its ends to the first and the second shield part.
