    In one embodiment the spring comprises a coil which extends through a coiling angle which is slightly less than 360 DEG . The end portions of the coil are curved in a direction for decreasing the pitch of the helix in the working position of the spring between two surfaces. This spring assumes such position that it comes in contact at two points with each of these surfaces and the forces are distributed in an excellent manner. Application in particular to the mounting of rollers on trunnions of homokinetic tripod joints.

    专利说明:

    Its axis does not exceed 360. And the ends of the 2 and 3 turns are flattened and bent in the direction of the spring step in the free state, and the opposite supporting surfaces 4, 5 and 6, 7 of the coil are made convex. This makes it possible to eliminate the contact of the helical spring by cutting its edge with adjacent nodes. In addition, coil spring 1 of the coil spring can have a constant cross section and its length is chosen from the condition that the angle formed by the ends 2 and 3 of the spring in the perpendicular to its axis is within 540 and the spring height in free state NII is 6-10 times its thickness. In this case, the coil spring is shaped in such a way that it collapses towards the free ends. The screw spring can be made from both round wire section and wire with different section shapes, and since its contact with adjacent nodes is made by supporting surfaces 4, 5 and 6.7, the transfer of elastic force is well distributed.
    A helical spring is obtained as follows.
    From the spring with the adjacent turns and the diameter of the coil exceeding by about 25% the desired diameter of the spring produced, the coil blanks are cut and the bends of its ends are reinforced. This coil is then flattened by squeezing between two plates 8 and 9, inclined one with the other with a slope of from 3 to 10% depending on the wire diameter and turn coil diameter, so that the ends are between 20 and 40% of the wire diameter.
    During flattening, permanent inhibition is restored along the inner edges of the ends of the coil, the curvature of which was previously strengthened. The last machining operation consists in winding the scientific research institute of the part in shape onto an axis with a diameter smaller in size and such that, after elastic deformation, the internal diameter of the spring and its height in the free state are given values.
    Then the helical spring is subjected to quenching.
    A screw spring with small axial and radial clearances, designed for installation between two nodes, has good operational durability, since its contact with neighboring nodes is made by four bearing surfaces due to the fact that the angle formed by the ends SPRINGS in the plane perpendicular to its axis,
    5 does not exceed 360 or 540 °, and its ends are flattened and bent in the direction of the pitch of the spring coil,

    Invention Formula
    0 1. A screw spring with small axial and radial dimensions, designed for a DL91 installation between two nodes, containing one turn, is distinguished.
    5 in order to improve operational durability, the length of the coil is chosen from the condition that the angle formed by the ends of the spring in the plane perpendicular to its axis does not exceed. It rotates 360 ° and the ends of the coils are flattened and bent in the direction of the pitch of the spring coil in the free state, and the opposite supporting surfaces of the coil are convex.
