FIELD: machine building.
SUBSTANCE: invention relates to machine building. Proposed bumper comprises gauze resilient element locked by to and bottom plates to rest on the base. Base is composed by the plate with mounting holes. Lower plate is connected with the base. Top pressure plate is connected with the central ring covered by aligned ring jointed to the base. Between the lower end of the piston and bottom of the sleeve the polyurethane elastomer is located. Density of resilient mesh element external layers meshy structure is by 1.5 times exceeds density of its internal layers. Resilient mesh element is made combined from meshy frame filled with elastomer. Between mesh resilient element and bottom washer three intermediate damping layers are located. Between piston lower end and sleeve bottom additional resilient damping element is located made in form of helical spring, which turns are coated with polyurethane layer.
EFFECT: improved efficiency in resonant mode of vibration isolation.
