The invention relates to a snake-shaped combined oil ring, comprising two scrapping blades and a supporting ring, wherein the supporting ring is arranged between the scrapping blades; the scrapping blades and the supporting ring are split; and the scrapping blades are snake-shaped. The snake-shaped combined oil ring disclosed by the invention is simple in structure; and the split structure is convenient for assembling and disassembling. The space interval between the scrapping blades of the invention is large, so that the oil returning effect is well; and the weight of the snake-shaped combined oil ring is greatly lightened, the power consumption is reduced, and the physical inertia is low, so that the abrasion speed of the oil ring is slowed, and the service life of the oil ring is prolonged.
Description
technical field [0001] The invention relates to a piston ring used in a diesel engine, in particular to a serpentine combined oil ring. Background technique [0002] Most of the existing diesel engine oil rings are made of cast iron, which are heavy in weight, high in production cost, and complex in processing. Therefore, the oil ring itself has a large inertia, high energy consumption, fast wear and short service life during work. Contents of the invention [0003] In order to solve the above problems, the present invention provides a serpentine combined oil ring with reduced energy consumption, more oil return and long service life. [0004] The technical proposal of the present invention is: comprising two scraping blades and a supporting ring arranged between the scraping blades, the scraping blade and the supporting ring are in a split structure, and the scraping blade is in the shape of a snake. [0005] The structure of the invention is simple, the split structure ...
