Description
Technical field
The utility model relates to a kind of piston ring, and more particularly, it relates to a kind of scraping ring.
Background technique
Piston ring is the metal ring for embedding piston groove inside, and its effect includes sealing, adjustment machine oil (control oil), heat conduction (heat transfer) and guiding (supporting) four effect.Wherein, scraping ring is exactly for saving the piston ring of machine oil (control oil), and its effect suitably scrapes the lubricating oil be attached on cylinder wall, makes again casing wall is furnished with very thin oil film simultaneously, ensures the normal lubrication of cylinder and piston and ring, and keep normal oil consumption.To firing chamber be drawn to when the lubricating oil supplied is too much, oil consumption is increased, and due to the carbon deposit produced that burns, extremely bad to engine performance impacts.
At present, its frizing of scraping ring of the prior art is all scrape by the inner circle edge of scraping ring the lubricating oil be attached on cylinder wall, the oil scraped is caused to hoard on scraping ring end face like this, the oil scraped can be made again to be attached on cylinder wall, affect follow-up scraping effectiveness, and then have influence on frizing effect, oil consumption is increased.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is the scraping ring providing a kind of frizing excellent effect.
For achieving the above object, the utility model provides following technological scheme: a kind of scraping ring, by multiple ring section around forming, being connected, two rings are intersegmental is formed with otch, one end end face of described ring section is provided with oil guide slot, and a sidewall of described oil guide slot is inclined to set, and the described sidewall that is inclined to set is crossing with scraping ring inwall, the end face that each described ring section is provided with oil guide slot is provided with the first groove of at least one, described first groove run through ring section outer side wall and with oil guide slot conducting.
The utility model is set to further: the rectangular trapezoidal setting of cross section of described oil guide slot, and the hypotenuse of described right-angled trapezium is crossing with scraping ring inwall.
The utility model is set to further: each described ring section is relative to one end end face being provided with oil guide slot being provided with at least one the second groove, the inside and outside sidewall of described second groove ditch grooved ring section.
The utility model is set to further: the degree of depth of described oil guide slot is greater than the degree of depth of the first groove, and the degree of depth of described first groove equals the degree of depth of the second groove.
The utility model is set to further: described scraping ring is provided with locating stud, and in a described locating stud ring section located therein, described locating stud and oil guide slot are located on same end face.
The utility model is set to further: the groove outer side wall of described scraping ring being provided with cross section semicircular in shape.
In sum, the oil under extension is collected by oil guide slot and by the first groove by outside the oil guiding scraping ring in oil guide slot, the oil under hanging effectively can be avoided again to be adsorbed onto on cylinder wall, improve the frizing effect of scraping ring by the utility model scraping ring.

Fig. 2 is the structural representation two of scraping ring;
Fig. 3 is the rear view of scraping ring;
Fig. 4 is the front view of scraping ring;
Fig. 5 is that the A of Fig. 4 is to sectional view.
Reference character: 1, ring section; 2, oil guide slot; 3, the first groove; 4, groove; 5, otch; 6, locating stud; 7, the second groove.
Embodiment
Referring to figs. 1 through Fig. 5, the utility model scraping ring is described further.
Be a kind of mode of execution of the utility model scraping ring as shown in Figures 1 to 5, by multiple ring section 1 around forming, the utility model is set to three, otch 5 is formed between the two ring sections 1 that are connected, one end end face of described ring section 1 is provided with oil guide slot 2, one sidewall of described oil guide slot 2 is inclined to set, the described sidewall that is inclined to set is crossing with scraping ring inwall, the end face that each described ring section 1 is provided with oil guide slot 2 is provided with the first groove 3 of at least one, described first groove 3 run through ring section 1 outer side wall and with oil guide slot 2 conducting.To be collected hanging lower oil by oil guide slot 2 by said structure and by the first groove 3 by outside the oil guiding scraping ring in oil guide slot 2, the oil under extension effectively can be avoided again to be adsorbed onto on cylinder wall, improve the frizing effect of scraping ring.
As shown in Figure 5, the rectangular trapezoidal setting of cross section of described oil guide slot 2, and the hypotenuse of described right-angled trapezium is crossing with scraping ring inwall, this vibrational power flow can allow the oil scraped automatically flow in oil guide slot 2, effectively avoids the oil under hanging again to be adsorbed onto on cylinder wall.
As shown in Fig. 2 Fig. 3, each described ring section 1 is relative to one end end face being provided with oil guide slot 2 being provided with at least one the second groove 7, the inside and outside sidewall of described second groove 7 ditch grooved ring section 1, each ring section 1 is provided with two the second grooves 7 in the utility model.
Further, the degree of depth of described oil guide slot 2 is greater than the degree of depth of the first groove 3, and the degree of depth of described first groove 3 equals the degree of depth of the second groove 7.
As shown in Figure 2, described scraping ring is provided with locating stud 6, in a described locating stud 6 ring section 1 located therein, described locating stud 6 is located on same end face with oil guide slot 2, and locating stud 6 arranges, for anti-stop ring section 1, relative dislocation occurs.
As shown in Figure 1, Figure 2 with shown in Fig. 5, the outer side wall of described scraping ring is provided with the groove 4 of cross section semicircular in shape, groove 4 is arranged between the clamping owing to installing encirclement scraping ring, and clamping element belongs to prior art to those skilled in the art, does not illustrate in the utility model.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
