RADIAL vibration dampers with free flow and appliances with a damping system, comprising RADIAL vibration dampers

摘要

1. Radial vibration absorber comprising a cylindrical outer sleeve (2) adapted to be coupled to a first member comprising an inner wall (2a) and capable of receiving the inner shaft (3) adapted to be coupled to a second element, ensuring the possibility of rotational movement the inner shaft (3) and a cylindrical outer sleeve (2) relative to each other, friction means (5) configured to capture the radial inner shaft (3) and thereby creating friction forces ensuring quicklime Ia rotary motion, and an inner sleeve (4) rotatably mounted in the outer sleeve (2) and comprising an outer wall (4a), opposite the inner wall (2a) of the outer sleeve (2) and an internal axial passage (4b), in which is an inner shaft (3), characterized in that it comprises a system (2b, 4c, 7 and 8) rotational limit between the inner sleeve (4) and the outer sleeve (2), allowing rotation between the outer sleeve (2) and the inner sleeve (4) within a predetermined range of the freewheel on which no friction means (5) driver running and blocking the rotation between the outer sleeve (2) and the inner sleeve (4) by applying the friction means (5), the radial frictional grip means (5) the inner shaft (3) creates frictional force that provides rotational damping dvizheniya.2. . Radial vibration damper according to claim 1, characterized in that something internal friction means (5) arranged radially in the internal axial channel (4b) and create a frictional force, impact, at least on the inner sleeve (4); - a system (2b , 4c, 7, 8) limiting rotation comprises at least one axial channel (7) disposed between the inner
