Abstract
The invention discloses an engine oilring with low friction work. The engine oilring is used for being arranged on a piston in a sleeving manner and comprises an oilring body, wherein the working face of the oilring body is concave; the concave structure forms two oil scraping blades; each of the oil scraping blades gradually shrinks from bottom to head. The engine oilring can meet the engine demand of reducing engine oil consumption without increasing the elastic force of a piston ring and also can reduce the friction work loss of the engine piston ring.
Description
Technical field
The present invention relates to motor oil ring field, particularly a kind of motor oil ring of low frictional work.
Background technique
Pot type piston ring and cylinder sleeve surface of contact are overall Cylindrical Surfaces Contact, and its area of contact is very large.In order to comply with the market demand, the engine oil consumption of motor needs to reduce further.In the face of the piston ring of Cylindrical Surfaces Contact of common integral, the elastic force that usually can only increase piston ring is pressed in specific pressure in cylinder liner to improve piston ring, thus the frizing effect of reinforcement piston ring.But increasing piston ring elastic force simply can cause the secondary frictional work of piston movement to increase, and causes energy loss.
The information being disclosed in this background technique part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the present invention is to provide a kind of motor oil ring of low frictional work, the elastic force of piston ring need not be increased, just can meet the demand that motor reduces engine oil consumption, the loss of engine piston ring frictional work can also be reduced simultaneously.
For achieving the above object, the invention provides a kind of motor oil ring of low frictional work, it is used for being set on piston, this motor oil ring comprises oil ring body, the working surface of oil ring body is matrix, this concave structure forms upper and lower two panels frizing sword, every sheet frizing sword from bottom to head be gradually-reducing shape.
Preferably, the end face of frizing sword is stepped shape, and high-order step surface is used for contacting with cylinder sleeve.
Preferably, oil ring body has and only has an opening.
Compared with prior art, the present invention has following beneficial effect: the motor oil ring of the low frictional work of the present embodiment is by increasing frizing sword with reduction frizing sword and by the area of contact of cylinder sleeve, the loss of effective reduction piston-ring friction merit, effective reduction Oil Consumption of Engine, processing is simple, perform convenience, with low cost, be easy to promote.
Accompanying drawing explanation

Fig. 2 is the partial sectional view of the motor oil ring according to low frictional work of the present invention;
Fig. 3 is the use schematic diagram of the motor oil ring according to low frictional work of the present invention.
Main Reference Numerals illustrates:
1-motor oil ring, 2-frizing sword, 3-cylinder sleeve.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As shown in Figure 1 to Figure 2, according to the motor oil ring 1 of a kind of low frictional work of the specific embodiment of the invention, it is used for being set on piston, this motor oil ring 1 comprises oil ring body, the working surface of oil ring body is matrix, this concave structure forms upper and lower two panels frizing sword 2, every sheet frizing sword 2 from bottom to head be gradually-reducing shape.
In such scheme, by the working surface of motor oil ring is designed to concave structure, the working surface of this concave structure forms upper and lower two panels frizing sword 2, and every sheet frizing sword 2 is gradually-reducing shape from bottom to head, can reduce the working surface of oil ring 1 and the area of contact of cylinder sleeve 3.Owing to adding frizing sword, the elastic force of piston ring need not be increased, just can meet the demand that motor reduces engine oil consumption, the loss of engine piston ring frictional work can also be reduced simultaneously.
As a kind of preferred embodiment, the end face of frizing sword 2 is stepped shape, and high-order step surface is used for contacting (see Fig. 3) with cylinder sleeve 3.In the present embodiment, frizing sword 2 takes the design of height structural ledge, reduce further the area of contact of working surface and cylinder sleeve 3.It should be noted that, this motor oil ring need in conjunction with the cylinder sleeve 3 of cylinder block, piston with the use of, when tangential elasticity of piston ring one timing, due to the reduction of the effective work area of motor oil ring, the specific pressure of piston ring working surface on cylinder sleeve increases, and effectively improves the frizing effect of motor oil ring.
As a kind of preferred embodiment, oil ring body has and only has an opening.
To sum up, the motor oil ring 1 of the low frictional work of the present embodiment is by increasing frizing sword 2 and reducing frizing sword 2 and by the area of contact of cylinder sleeve 3, effectively reduce the loss of piston-ring friction merit, effective reduction Oil Consumption of Engine, processing is simple, performs convenience, with low cost, be easy to promote.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
