PLATE VIBRATION ISOLATOR Russian patent published in 2016 - IPC F16F3/02 F16F7/08 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Vibration isolator contains a frame designed as an upper platform for installation vibration isolated object and a lower base for arranging of stroke limiters of the unit of disk-shaped elastic elements. Adjustment plate is fixed to the upper platform by means of fastening elements. Elastic elements connect the upper platform to the lower base, on which a baffle plate is placed. Base of the frame vibration isolator in the place of contact with disk-shaped elastic elements is coated with a frictional material. Unit of disk-shaped elastic elements consists of four belleville springs of various height and angle of inclination to the vibration isolator axle. Belleville washers through spacer rings are placed on the vibration isolator axle and fixed with the help threaded chank and nut. Each of belleville washers has in a base a horizontal ring annular circular beading, resting on the lower base. Vibration isolator axle is rigidly connected to upper platform of frame. Spacer rings are made from vibration damping material, for example polyurethane. Annular flanged edges on the side in contact with base, are coated with friction material layer.

EFFECT: improved efficiency in resonant mode of vibration isolation.
