Abstract
The utility model discloses a piston for prolonging the service life of an engine. The utility model comprises a piston body and a piston ring groove arranged on the piston body. The utility model is characterized in that a skirt part of the piston body is provided with a plurality of tapered blind holes and a plurality of tapered through holes. When the piston body moves along a cylinder body, lubricating oil on the inner wall of the piston body is used for lubricating the skirt part of the piston body and the circumferential wall of the cylinder body via the tapered through holes, and the lubrication action of a power machine on the piston body and the wall of the cylinder body when a cold vehicle starts can be ensured via the oil storage effect of the tapered blind holes in order to reduce the abrasion of the engine. The utility model has the advantages of simple structure, easy manufacturing, persistent forced lubrication action on the piston body and the cylinder body and long service life for the engine.
Description
The utility model relates to a kind of mechanical fitting, specifically a kind of motor piston in working life that prolongs.
At present, causing the early stage principal element of reporting for repairment of damaging of piston internal-combustion dynamic power machine and non-internal combustion piston engine tool is that matching gap between piston body and the cylinder block is because of wearing and tearing excess cause burning machine oil, power decline, piston knock etc.Trace it to its cause be exactly because of between piston body skirt section and the cylinder block because of insufficient lubrication, be difficult for to form lubricant film, the moment in that dynamic power machine starts, make piston body and cylinder block generation Metal Contact, form excess and wear and tear the above-mentioned many drawbacks of appearance of a specified duration.
The purpose of this utility model just is to design a kind of simple in structure, is easy to processing, and piston body and cylinder block are had lasting, forced lubrication and can prolong the motor piston in working life.
The concrete technological scheme that realizes the utility model purpose is: piston comprises piston body and the piston ring groove of establishing thereon, and characteristics are that the skirt section of piston body has several conical through-holes and several tapered blind hole.
The utility model is simple in structure, is easy to processing, and piston body and cylinder block are had lasting, forced lubrication, can reduce the wearing and tearing of motor, prolongs the working life of dynamic power machine.
Fig. 1 is the utility model structural representation
Fig. 2 is that Figure 1A-A is to view
Fig. 3 is Fig. 2 and cylinder block assembling schematic representation
Among the figure: 1-cylinder block 2-piston body 3-piston ring 4-tapered blind hole 5-conical through-hole 6-piston ring groove
Below in conjunction with accompanying drawing the utility model is described in detail:
Consult Fig. 1, Fig. 2, what this used novel employing is pot type piston, and it comprises piston body 2 and establish thereon piston ring groove 6 that characteristics are to have several tapered blind hole 4, several conical through-holes 5 in the skirt section of piston body 2.
Consult Fig. 3, when piston body 2 when cylinder block 1 moves, what the moving element in the body did not stop gets rid of lubricant oil to the inwall of piston body 2, by doing pressure lubrication around 5 pairs of piston skirts of conical through-hole and the cylinder wall, the cone structure design helps the diffusion of lubricant oil, piston ring 3 is scraped unnecessary lubricant oil to tapered blind hole 4 along cylinder block 1 inwall simultaneously, tapered blind hole 4 has the effect of storage lubricant oil and lube pistons body 2 and cylinder block 1 inwall, what is more important when dynamic power machine stops because of the oil storage effect of tapered blind hole 4, can guarantee dynamic power machine lubrication to piston body 2 and cylinder block 1 inwall when starting a cold engine, reduce the wearing and tearing of motor.
Claims (1)
