FIELD: machine building.SUBSTANCE: bumper consists of flat elastic and friction damping elements. Flat resilient elements are made as a package of arc-type resilient elements consisting of flat springs alternating in mutually perpendicular directions and resting against a base. Each flat spring consists of horizontal flange and two lateral flanges bent at angle of 135° to horizontal flange and provided with thrust sections at ends. Damping element is a compound one and consists of a friction part and an elastic part. Friction part is made as bushes with flanges at the ends and a section of a rope wound on the bushes in a closed loop. Sleeves are connected with flexible elements by rivets and are made from sintered friction material based on copper. Elastic part is composed of resilient damping ring from elastomer embracing outside pigtail. Installation of elastic part of damping element is carried out in static state with pulling onto friction part. On base under rivets three intermediate damping layers are located.EFFECT: higher efficiency of vibration isolation.1 cl, 1 dwg |
