矩形截面弹簧的优然是:在同样的载荷下,矩形截面所受的入应力要比圆形小得多。第二届美国机床展览会展出了丹利公司提供的矩形截面弹簧。该公司把现有的730种弹簧分成四大类并涂上颜色,即轻型(棕色)、中型(蓝色)、重型(红色)、特重型(黄色),因以颜色分类,一目了然。制造弹簧的线材全系梯形戳面,卷绕成弹簧后因内外曲率半径不同,内圈材料受压缩胀粗,外圈材料受拉伸变细,从而原来的梯形截面变成了矩形。承受不同载荷的弹簧内外径可以制得完全一样,只须改变弹簧线材的厚薄即可,因此选用和
The advantage of a rectangular section spring is that, under the same load, the rectangular section receives much less stress than a circular one. The 2nd American Machine Tool Show presented a rectangular section spring supplied by Danley. The company divides its existing 730 springs into four major categories and colors, namely light (brown), medium (blue), heavy (red) and extra heavy (yellow), at a glance for color. The spring trapezoidal wire traverses all the trapezoidal pallets. When the coil is wound into a spring, the inner and outer radii of curvature are different due to different inner and outer radii of curvature. The material of the inner ring is compressed and expanded coarsely, and the material of the outer ring is drawn and thinned. As a result, the original trapezoidal cross section becomes a rectangle. To withstand different load spring diameter can be made exactly the same, only need to change the thickness of the spring wire can, so the choice and
