The invention relates to a lotus root-shaped combined oil ring which comprises a lotus root-shaped doctor blade main body and a bolt pin, wherein the doctor blade main body is an elastic doctor blade; an open hole is formed in the circumferential direction of the doctor blade main body; the bolt pin is arranged in the open hole of the doctor blade main body in a penetrating manner; and one end of the bolt pin is fixedly arranged on the doctor blade main body. The lotus root-shaped combined oil cup disclosed by the invention has the advantages of simple structure, great space interval of the doctor blade and favorable oil return effect. According to the lotus root-shaped combined oil cup disclosed by the invention, the weight is greatly reduced; the energy consumption is reduced, the physical inertia is small, the wear speed is retarded and the service life of the oil ring is prolonged. The doctor blade is the elastic doctor blade; in addition, one end of the bolt pin is fixedly arranged on the doctor blade; and the doctor blade is convenient to close and is favorable in sealing property.
Description
technical field [0001] The invention relates to a piston ring used on a car, in particular to a lotus-shaped 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 lotus-shaped combined oil ring with light weight, good flexibility and long service life. [0004] The technical solution of the present invention is: comprising a lotus-shaped scraper main body and a pin, the scraper main body is an elastic scraper, the scraper main body is provided with openings in the circumferential direction, and the pin is passed through the opening of the scraper main body. One end of the hole is fixed on the main body of th...
