Abstract
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
The present invention relates to the piston ring that uses on a kind of car, relate in particular to a kind of lotus root shape combined oil ring.
Background technique
Existing diesel engine oil ring is processed for cast iron mostly, and weight is heavier and cost of production is higher, processed complex, so the oil ring its own inertial is big when work, energy consumption is bigger, the rate of wear is fast, and working life is short.
Summary of the invention
The present invention for overcome the above problems provide a kind of in light weight, pliability good, the lotus root shape combined oil ring of long service life.
Technological scheme of the present invention is: comprise the scraping blade main body and the latching of lotus root shape, described scraping blade main body is an elastic doctor blade, and this scraping blade main body is circumferentially with perforate, and described latching is through in the perforate of scraping blade main body and has an end to be fixed on the scraping blade main body.
The present invention is simple in structure, and the scraping blade space interval is big, and oil return is effective; Weight of the present invention alleviates greatly, and energy consumption reduces, and physics inertia is little; Slow down the rate of wear of oil ring, prolong the working life of oil ring, scraping blade is an elastic doctor blade; And an end of latching is fixed on the scraping blade, and scraping blade is closed convenient, good seal performance.
Description of drawings
Fig. 1 is a structural representation of the present invention.
1 is the scraping blade main body among the figure, the 2nd, and latching.
Embodiment
