The invention relates to a flexible reversed-U-shaped integral steel oil ring, comprising an annular base body and a spiral expansion spring, wherein the annular base body has a U-shaped section and consists of an upper oil scrapping blade, a lower oil scraping blade and an annular groove; and the two oil scraping blades are in parallel with each other. The flexible reversed-U-shaped integral steel oil ring disclosed by the invention is simple in structure, novel in modeling and convenient for assembling so as to replace the cast iron combined oil ring formed by two scrapping blades and a liner spring, so that raw materials can be saved effectively, softer elasticity and fitting ability of a piston ring can be guaranteed, further, the abrasion resistance and sealing performance of the product are greatly improved, and the self-tension is more durable; and the radial pressure of the piston ring is distributed uniformly, the oil consumption is reduced, and the piston ring is prevented from being silted up and bonded.
Description
technical field [0001] The invention relates to an oil ring used on an internal combustion engine of a high-grade car, in particular to a flexible inverted U-shaped integrated steel oil ring. Background technique [0002] Most of the oil rings used in existing cars are made of cast iron, which is heavy, has high production costs, and complicated processing. Therefore, the oil ring itself has a large inertia, large energy consumption, fast wear and long service life during work. short. Contents of the invention [0003] In order to solve the above problems, the present invention provides a flexible inverted U-shaped integrated steel oil ring with simple structure, good wear resistance, good sealing performance and good elasticity. [0004] The technical solution of the present invention is: comprising an annular base body and a helical expansion spring, the annular base body has a U-shaped cross-section, and is composed of upper and lower oil scraping blades and a ring gro...
