Abstract
A kind of low oil consumption piston ring oil ring, the utility model relates to the technical field of structures of piston ring oil ring.Comprise piston ring oil ring body and helical supporting spring, oil ring body is provided with monolateral nose shape frizing sword, and the periphery of described frizing sword is the conical surface, and the inner side surface of frizing sword is nose shape, and the outer side surface of frizing sword is provided with chamfering.The utility model by arranging monolateral frizing sword and oil scraper inner side surface is nose shape on ring body, increase piston ring to cylinder by touch pressure, namely the contact area by reducing oil ring working surface and cylinder improves the surface pressure of ring to cylinder wall, strengthen oil ring frizing and the oily effect of control, realize the object reducing engine oil consumption.By Experimental Comparison, the utility model and conventional oil chain rate engine oil consumption can reduce by more than 50%, improve engine fuel economy, are applicable to reciprocating diesel engines piston ring.
Description
Technical field
The utility model relates to the technical field of structures of piston ring oil ring.
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.Piston ring for combustion engines has two kinds, and one is compression ring, and another kind is oil ring, and wherein oil ring plays Controlling oil effect.
The piston ring oil ring of general design is symmetric double frizing sword structure, and this structure oil ring frizing sword is wider with cylinder contact face, and face pressure is little, frizing weak effect.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides the piston ring oil ring that a kind of diesel engine frizing is effective.
The utility model comprises piston ring oil ring body and helical supporting spring, and oil ring body is provided with monolateral nose shape frizing sword, and the periphery of described frizing sword is the conical surface, and the inner side surface of frizing sword is nose shape, and the outer side surface of frizing sword is provided with chamfering.
The utility model by arranging monolateral frizing sword and oil scraper inner side surface is nose shape on ring body, increase piston ring to cylinder by touch pressure, namely the contact area by reducing oil ring working surface and cylinder improves the surface pressure of ring to cylinder wall, strengthen oil ring frizing and the oily effect of control, realize the object reducing engine oil consumption.By Experimental Comparison, the utility model and conventional oil chain rate engine oil consumption can reduce by more than 50%, improve engine fuel economy, are applicable to reciprocating diesel engines piston ring (special heavy diesel engine piston ring).
In addition, the tapering of the conical surface described in the utility model is 0 ° ~ 2 °.Frizing sword designs this cone angle, although the conical surface weares and teares, gradually Zhejiang disappears, and ring and cylinder surface of contact are also less, and face pressure is still comparatively large, and high surface pressure can continue the frizing effect of guarantee ring.
The nose angle of described nose shape is 15 ° ~ 25 °; The angle of described chamfering is 20 ° ~ 40 °.Still can keep original in cylinder contact height after piston ring in use weares and teares, therefore frizing effect can be kept in the long term.
Accompanying drawing explanation
Fig. 1 is cross section structure schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises oil ring ring body 1 and helical supporting spring 4.
Oil ring body 1 is provided with monolateral nose shape frizing sword 2, the periphery of this frizing sword to be tapering the be conical surface of 0 ° ~ 2 °, the inner side surface 3 of frizing sword for nose angle be the nose shape of 15 ° ~ 25 °, the outer side surface of frizing sword is provided with the chamfering that angle is 20 ° ~ 40 °.
The utility model improves oil ring frizing ability, and reduce consumption of lubricating oil, by Experimental Comparison, the utility model and conventional oil chain rate engine oil consumption can reduce by more than 50%, improve diesel engine Economy.
