Abstract
The utility model discloses a piston oil ring with drilled holes, which comprises a ring body of the oil ring and an internally supporting spiral spring, wherein circular oil return holes are drilled in an oil collecting tank of the ring body of the oil ring. By adopting the piston oil ring, the ring height of a cast iron oil ring can be 1.5mm or thinner without influencing the strength of the ring body. Compared with the traditional oil ring with milled oil holes, the piston oil ring has the advantages that the breakage-resistant strength is greatly improved, hole drilling processing has a much slighter influence on the deformation of end surfaces and a working surface of the ring than oil hole milling processing, the following performance of the ring body is greatly improved, and a positive influence is formed on the oil consumption reduction, particularly the early-stage oil consumption of an engine, so that piston oil ring is more suitable for the requirement of low emission of the engine at present.
Description
One, technical field:
The utility model relates to a kind of oil piston ring, is specifically related to a kind of boring oil piston ring.
Two, background technique:
Along with the appearance of national energy-saving and emission-reduction policy, the motor car engine recent years obtains more fast-developing, and two combined oil rings use comparatively general.For the quality that reduces piston-ring packing, tracing ability and the frizing effect that reduces inertia loss, raising oil piston ring, high do more and more thinner of ring.Most of motor oil ring ring height drops to below 3 millimeters from 4 millimeters or 5 millimeters gradually, and especially to petrol engine, oil ring ring height develops to the direction that approaches below 2 millimeters or 2 millimeters.
Because of the ring body of oil ring is provided with regular spill port, spill port can weaken the intensity of ring body.For traditional oilhole that mills, cast iron oilhole ring body intensity has satisfied not requirement gradually.One, it is long to mill the oilhole length of oilhole oil ring, and the ring body intensity at oilhole place is little, make with using process in cause ring body to rupture easily; Two, it is big to ring body cutting force to mill oilhole, causes ring body cylindrical generation deformation easily, and deformation ring circularity is bad unfavorable and occur scuffing of cylinder bore easily to early stage engine oil consumption.
Three, summary of the invention:
The utility model technical problem to be solved has provided and a kind ofly can satisfy the more thinning and do not influence the boring oil piston ring of ring body intensity of motor oil ring ring height.
For solving the problems of the technologies described above, the utility model boring oil piston ring comprises oil ring ring body, interior support helical spring, is drilled with circular spill port on the oil trap of said oil ring ring body.
Technique scheme is bored circular spill port at ring body oil trap place, and can confirm the number of circular spill port and the size of oilhole according to the engine performance needs, and is more more convenient, more practical than milling oilhole.The ring height of having realized the cast iron oil ring can be accomplished 1.5 millimeters even thinner and do not influence the intensity of ring body.Milling the oilhole oil ring with tradition compares; Improved anti-rupture strength widely; Boring processing is much littler to the deformation effect of ring end face and working surface than milling oilhole processing; Improved the ring body tracing ability greatly, produced active influence, be more suitable for existing motor low emission requirement reducing the particularly early stage oil consumption of engine motor oil consumption.In addition, boring processing is much littler for the deformation effect of ring end face and working surface than milling oilhole processing, and is obvious to improving early stage engine oil consumption effect.
Four, explanation accompanying drawing:
Accompanying drawing is the structural representation of the utility model boring oil piston ring.
Five, embodiment:
Referring to accompanying drawing, the utility model boring oil piston ring comprises oil ring ring body 1 and interior support helical spring 2, is drilled to circular spill port 3 with piston ring boring numerical control machine tool on the oil trap of oil ring ring body 1.Spill port 3 can be confirmed oilhole spacing, oilhole diameter, oilhole number according to the engine performance demand.
Claims (1)
1. a boring oil piston ring comprises oil ring ring body, interior support helical spring, it is characterized in that: be drilled with circular spill port (3) on the oil trap of said oil ring ring body (1).
