Abstract
Vibro-isolation of connections of structural units of hand tools consisting of a vibro-isolator with a constant reaction force is characterized by that on the side of the body /3/ of the compressed-air engine there is an upper /9/ and lower /10/ elastic guide being the first stage of vibro-isolation in the directions /x/ and /y/ perpendicular to the axis of symmetry of the tool, whereas in the main direction /z/ parallel to the axis of symmetry of the tool vibro-isolation is ensured by an elastic system consisting of a vibro-isolator /1/ with a constant reaction force connected to the body /3/ of the compressed-air engine through a spring washer /2/, whereas on the side of the grip /4/ vibro-isolator /1/ with a constant reaction force is mounted through a spring washer /6/ and sleeve /7/ being at the same time the second stage of vibro-isolation of the grip /14/. Moreover, the second stage of vibro-isolation for the left operator's hand is the grip itself in the form of a spring sleeve /13/ screwed onto the end-portion of the body-housing /8/, whereas vibro-isolation of the supply system is formed of an intermediate sleeve /17/ and a silent-block connection of the supply unit /15/ with the grip /14/.
