FIELD: machine building.
SUBSTANCE: vibration insulating system contains four bumpers installed on base and rigidly connected by means of bolts with the support platform. Each bumper contains base and pendulum suspension. The pendulum suspension contains thread stud connected by one end with the support lever, and by another end - with thrust washer and nut connected with bushing linked with ring. Top flange of the resilient element inserted in the protective casing rests against bushing. Base of each bumper is made box-like connecting horizontal support plates connected with vertical partitions. Each of the resilient elements of the bumper is made as vibration dampening spring. Spring contains body made out of helical hollow steel tube. Additional resilient steel tube is installed coaxially with clearance inside the body. In clearances between the tubes the polyethylene friction element is located. Surfaces of casing and additional resilient steel tube touch surfaces of the friction elements. Coaxially to the casing the helical continuous resilient rod is installed.
EFFECT: increased efficiency of vibration isolation in resonance mode.
