Abstract

DC60 The coil spring reduces Hertzian stress on the first coil and the bending stress at the end of the coil.The coil spring is made of composite wire. The assembly wire is wrapped in a coil and has Coiled ends on the movable side The end of the coil continues with the first coil of the coil spring and is shifted through the diameter. centered on the outside or inside of the coil spring relative to the first coil to form a vertical gap between the coiled end and the first coil in the unloaded free state on the coil spring because of this gap A helical spring with a first coil and a first coil can be treated entirely by shot peening. The first coil is subjected to torsion stress and Hz stress. (contact stress) due to the coiled end that receives the hertz stress. The height has been shifted in diameter in the inner or lateral direction. outside of the coil spring relative to the first coil The contact point on the first coil is shifted its diameter in the outer or inner direction to reduce the torsional stress on the first coil. The shaped slides and gaps between the first winding and the first coil have the effect of preventing excessive bending stresses and breaking of the winding ends when the first winding and the first coil are bonded. and make it fall out in repetitive gaps The coil spring reduces Hertzian stress on the first coil and the bending stress at the end of the coil. The coil spring is made of composite wire. The assembly wire is wrapped in a coil and has Coiled ends on the movable side The end of the coil continues with the first coil of the coil spring and is shifted through the diameter. centered on the outside or inside of the coil spring relative to the first coil to form a vertical gap between the coiled end and the first coil in the unloaded free state on the coil spring because of this gap A helical spring with a first coil and a first coil can be treated entirely by shot peening the first coil to the torsion stresses and the Hertz stresses. (contact stress) due to the stressed coil tip of the Hertz. The height has been shifted in diameter in the inner or lateral direction. outside of the coil spring relative to the first coil The contact point on the first coil has been shifted in diameter in the direction of on the outside or inside to reduce the torsional stress on the first coil. Formed slides and gaps placed between the end of the coil and the first coil, effective in preventing excessive bending stress and lack of The end of the coil, when the end of the coil and the first coil are interlaced and loosened in the gap.
