VIBRATION ISOLATOR FOR TEXTILE MACHINES Russian patent published in 2017 - IPC F16F15/67 F16F3/04 

FIELD: machine engineering.

SUBSTANCE: vibration isolator contains a housing in the form of a base and a lid with a hole for a vertical post and a spring with an integrated damper. The lid is connected to a vibration-isolating object by means of an S-shaped lever. A bevel is made on the lid, and bend site of the upper shelf of the S-shaped lever rests upon the bevel. The lower shelf is fixed with a stud at the base of the vibration isolator. The spring is made of screw cylindrical form and consists of two parts with facing ends. The first spring part has the rectangular section turns with rounded edges, and the second part is made hollow. The facing end of the first part is located in the cavity of the second part. The contacting spring parts segmental profile gaps are filled with antifriction lubricant. The packing seal is mounted at the end of the second spring part to prevent the lubricant leakage. The first part of the screw spring is enclosed by the tube from the damping material, for example, polyurethane. The lubricant for friction units, containing the mineral oil and the lubricating additive, is used as the spring contacting parts antifriction lubricant.

EFFECT: increased vibration isolation efficiency.
