一种变截面少片簧

Variable-section fewer-piece spring

Abstract

The utility model relates to a variable-section fewer-piece spring. The spring is formed by overlaying a plurality of pieces of steel plate spring pieces which become thinner from the thicker center to the two ends along the length direction of steel plates, or change the piece width and the piece thickness uniformly and gradually; the middle parts of the spring pieces are fixed by bolts; the end part of each spring piece is pressed into certain radian; the tail ends of all the spring pieces are contacted; and certain gaps are left among the pieces. The variable-section fewer-piece spring is simple in structure, can reduce noise when in use, reduces contact fatigue and prolongs the fatigue life.
一种变截面少片簧,是将若干片沿钢板长度方向中心较厚向两端逐渐变薄,或者片宽和片厚均渐变化的钢板簧片叠加而成,中部通过螺栓固定,所述簧片端部压成一定弧度,各簧片末端接触,片与片之间留有一定的间隙。本实用新型结构简单,在使用时可以降低噪音、减少接触疲劳并延长疲劳寿命。
