Abstract
The invention provides an oil ring of a piston ring set of an internal combustion engine, and relates to the technical field of a structure of a combined oil ring of a piston ring set of a diesel engine. The oil ring comprises an upper oil scraper ring and a lower oil scraper ring, wherein the upper oil scraper ring is provided with an opening, the lower oil scraper ring is provided with an opening, and the upper oil scraper ring and the lower oil scraper ring are mutually overlapped. The oil ring is characterized in that the openings of the upper oil scraper ring and the lower oil scraper ring are staggered by 60-120 degrees, the circumference of the upper oil scraper ring is uniformly provided with 6-12 oil drain grooves, the circumference of the lower oil scraper ring is uniformly provided with 6-12 oil drain grooves, the oil drain grooves of the upper oil scraper ring and the oil drain grooves of the oil drain grooves of the lower oil scraper ring are the same in number, correspond with each other one by one, and are also oppositely arranged to form oil drain holes, and the inner circular surfaces of the oil scraper rings are provided with a wavy support spring. The oil ring has the advantages that the defect of poor oil scraping property and certain side gap between an oil ring and a piston groove of the traditional oil piston assembly of the diesel engine are overcome, and the condition of oil mixing of the engine during idling is effectively prevented.
Description
Technical field
The present invention relates to a kind of technical field of structures of piston ring, be specifically related to the combined oil ring in a kind of piston ring of diesel engine group.
Background technique
Piston ring is one of key components and parts of internal-combustion engine, and along with the development of modern automobile industry, motor requires more and more higher in discharge, fuel oil consumption and working life etc.Conventional diesel engine Piston volume tube oil ring adopts helical supporting spring oil ring (spring and ring body combination) usually, there is certain sideshake in piston ring and piston groove, along with piston ring excircle wearing and tearing sideshake constantly increases, thus cause altering oil, lubricating oil carry-over phenomenon during special heavy duty diesel engine idling is more serious.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, the Piston volume tube oil ring that a kind of diesel engine frizing is effective is provided, overcome conventional diesel engine Piston volume tube oil ring and piston groove exists certain sideshake, the defect of frizing poor performance.
The present invention includes a slice and be provided with the lower scraper ring that the upper scraper ring of opening and a slice are provided with opening, described upper scraper ring is relative with lower scraper ring mutually stacked, it is characterized in that: the opening of upper scraper ring and lower scraper ring is staggered 60 ~ 120 °, 6 ~ 12 oil extraction grooves are uniformly distributed in the circumference of upper scraper ring, the circumference of lower scraper ring is uniformly distributed 6 ~ 12 oil extraction grooves, upper scraper ring is identical with the oil extraction groove number on lower scraper ring, oil extraction groove one_to_one corresponding on oil extraction groove on upper scraper ring and lower scraper ring and be oppositely arranged formation oil drainage hole, at the inner headed face of two panels scraper ring, a waveform support spring is set.
This combined oil ring elastic force be evenly distributed and specific pressure distributing homogeneity good, during upper and lower two panels scraper ring combination, opening staggers 60 ~ 120 ° mutually, ensure that oil ring has enough drainback passages, there is fabulous frizing, oil return ability, move time and piston ring groove without sideshake, not along with piston ring excircle wearing and tearing, piston ring in sealed gap increases and alters oil, reduce engine oil consumption, effectively prevent lubricating oil carry-over phenomenon during engine idle simultaneously, improve fuel economy and Service Life of Piston Ring.
The height of upper scraper ring and lower scraper ring is equal, and upper scraper ring accounts for 1/2 of internal-combustion engine piston ring group oil ring height overall.
Accompanying drawing explanation
Fig. 1 is of the present invention bowing to schematic diagram.
Fig. 2 is that A-A in Fig. 1 is to section amplification figure.
Fig. 3 is the structural representation of upper scraper ring.
Fig. 4 be in Fig. 3 B-B to section amplification figure.
Fig. 5 is the structural representation of waveform support spring.
Fig. 6 is the deployed condition schematic diagram of waveform support spring.
Embodiment
As shown in Figure 1, 2, the present invention is made up of the lower scraper ring 2 that a slice is provided with the upper scraper ring 1 of opening 1-1, a slice is provided with opening 2-1 and a waveform support spring 3.
The height of the upper scraper ring 1 be made up of alloy iron casting and lower scraper ring 2 is equal, and upper scraper ring 1 or lower scraper ring 2 account for 1/2 of Piston volume tube oil ring height overall.
Upper scraper ring 1 is relative with lower scraper ring 2 mutually stacked, and the opening of upper scraper ring 1 and lower scraper ring 2 is staggered 60 ~ 120 °, is staggered 90 ° in this example.At the inner headed face of two panels scraper ring 1,2, a waveform support spring 3 is set.
As shown in Figure 2,3, 4, be uniformly distributed oil extraction groove 1-2 on eight in the circumference of upper scraper ring 1, be uniformly distributed eight lower oil extraction groove 2-2 in the circumference of lower scraper ring 2 equally.Lower oil extraction groove 2-2 one_to_one corresponding on upper oil extraction groove 1-2 on upper scraper ring 1 and lower scraper ring 2, and be oppositely arranged, form eight groups of oil drainage holes 4 respectively.
As shown in Figure 5,6, support spring makes flat wire by heat resisting alloy wire 55CrSi, is then pressed into wave, then be coiled into toroidal and be placed on ring inner circle.
Claims (2)
