    • 专利摘要:
    A spacer-expander member for holding one or two cylinder-engaging rails in a groove in a piston is formed to present a plurality of radially inwardly-directed spacer feet which are so located that they engage the groove bottom in a region spaced from the groove sides.

    (5) OIL RING
    V i
    The invention relates to mechanical engineering and can be used as an oil scraper ring mounted on pistons of various kinds of mechanisms .5
    The oil scraper ring is known, which contains a steel tape spring I-shaped profile in cross section with alternating axial and transverse ones. Overlapping each other, notches and spacers, which are uniformly distributed along its inner circumference and facing the inside of the piston groove, as well as at least one spring-supported lamellar ring l.
    In this device, the spacer legs are bent in such a way that their ends are in the zones of the corners of the piston groove and directed at an acute angle to the base of the groove.
    This arrangement of the spacer legs makes it difficult to center the assembled oil scraper ring relative to 25
    but the grooves of the piston and the mirrors of the cylinder-i ra.
    The purpose of the invention is to increase the accuracy of the centering of the ring relative to the groove in the piston and the cylinder mirror.
    The goal is achieved by the fact that the spacer legs of the spring are located outside the radius of rounding of the corners of the groove and are directed perpendicular to the base of the groove.
    FIG. 1 shows a ring, transverse section; ; in fig. 2 is a spring reamer circuit.

    The oil scraper ring contains lamellar rings 1, which are in contact with the mirror 2 of the cylinder 3, and the steel spring supporting them 4 of the I-shaped profile in cross-section. The cross section with alternating axially located and overlapping / overlapping each other slots 5 and spacer legs 6 equally spaced around the inner circumference of the spring extends inside the groove 7 of the piston 8 with the legs 6 placed outside the corners of the groove 7. When assembling the ring, the outer sides of the spring k are folded and placed on them one or two rings 1, after which the assembled oil scraper ring is installed in the groove 7 of the piston 8. Such an embodiment of the ring allows for precise centering of the ring relative to Navki piston and cylinder mirror. Claims of oil scraper ring containing steel tape spring of I-shaped profile in cross section with alternating axially located and overlapping slots and spacer legs evenly distributed around its inner circumference and facing the inside of the piston groove, and also smaller least one supported by a spring plate ring that is distinguished by. that, in order to increase the accuracy of the centering of the ring relative to the groove in the piston and the cylinder mirror, the spacer legs of the prumina are located outside the radius of rounding of the corners of the groove and directed perpendicular to the base of the groove.
