ELASTOMER SPRING

摘要

FIELD: machine building. ^ SUBSTANCE: according to first version spring corresponds to elongated elastomer object. External surface is located between the first and second lengthwise spaced ends; surface has four equally flat sides. Flat sides are positioned at equal distance from lengthwise axis parallel to that axis. A slanted arc-shaped angular section is located between each adjacent flat sides. Four slanted arc-shaped sections are arranged at equal distance from each other both in lengthwise and cross directions. According to the second version the spring is additionally featured with a reproducible curve of bending deflection under a load with an increasing coefficient. The coefficient at the section between initial value of side bending deflection and approximately 90 % of value of side bending deflection of the said spring is maintained constant. Width of each flat side is around 40-60 % of total width of the spring. In addition to the above said according to the third version the spring is made out of co-polyester polymer elastomer body with cross section of a square shape. Ends of elastomer object are perpendicular to lengthwise axis. Internal and external surfaces between ends form a wall. Thickness of the spring wall continuously increases in the direction from the flat side of external surface to the slanted arch-shaped angular section. ^ EFFECT: restricted radial inflection of spring and facilitation of required dependencies of deflection bending on load. ^ 14 cl, 6 dwg
