Torsion springs
Springs screw working in a share for the compression and tension.Springs screw working in a share for the compression and tension. Working on the compression spring in the unladen axles coils is arranged at a distance equal to skokowi winding. Spring strength in working condition is unladen axles coils arranged side by side. Compression springs are different from rozciąganych end coils. Spring pulled at both ends of the mesh is to enable its attachment. Springs with wire diameter of 7 millimeters and a half on the cold-rolling. Each spring after zwinięciu shall be subjected to heat treatment consisting of hardening and odpuszczaniu or - in the case of springs made of the so-called. Piano wire (wire cooled by hardening in the lead bath at a temperature of 500 degrees Celsius, and dragged the cold) - odpuszczaniu only. Hand-rolling screw springs are made in the vice. Before proceeding to the rolling of the spring should be highlighted the mandrel, on which spring is wound. Stem diameter should be less about one-fifth the diameter of the inner spring, because after nawinięciu and extension of the slackness in diameter. There are two types of screw springs zwijanych hand show a greater accuracy of the spring working on strength.
