Suspension arrangement with swing damper and method of damping thereof

摘要

The invention relates to the field of mechanical devices and methods intended for braking or damping the pendular movement, for instance, it relates to suspension arrangements connecting the arm of crane with rotator, about which the swinging movement is accomplished by the suspension arrangement. The aim of invention is to increase reliability, service life and to improve service quality of suspension arrangement. The arrangement contains suspension (1) with a slot wherein the crankcase block is located. The crankcase block includes two covers (2) and central figurative insert (3) with hub (6) that is mounted on grooves of sleeve (10). The hub is provided with blade wherein a damping hole (a) is made. The covers (2) are located movable with a possibility to accomplish swinging-rotating movement on diametrical protrusions of the hub (6). The central insert (3) is provided with outer protrusions (b) being in engagement with the surface (c) of rotator in running order. The suspension (1) is mounted on an axle (14) stationary connected with rotator (15); the axle passes through internal hole of sleeve (10).
