Abstract
An oil storage piston in favor of starting lubrication of an engine belongs to the engine machinery; an oil storage blind hole or an oil storage ring-shaped groove is formed at the lower part of a lubricant hole and an oil ring groove formed in the inside wall of a piston body; the upper end part of the oil storage blind hole or the oil storage ring-shaped groove is communicated with the lubricanthole and the oil ring groove; or the oil storage blind hole and the oil storage ring-shaped groove are formed at the lower part of the oil ring groove formed in the outer side wall of the piston body; and the oil storage blind hole and the oil storage ring-shaped groove are not communicated with the oil ring groove. The piston has the advantages that the structure is reasonable; the starting lubrication property of the engine or an air compressor is good; the short-time dry friction among the piston, an oil ring and a cylinder sleeve is eliminated during starting; the abrasion of spare partsduring starting is reduced; the starting operation is labor-saving; and the service life of spare parts is prolonged.
Description
Technical field
The utility model belongs to engine mechanical, relates generally to engine piston parts equipped on the various internal-combustion engines.
Background technique
At present, comprise the piston on the motor machine air compressor of various fuel such as being installed in gasoline, diesel oil, oil leab hole on its piston body madial wall or oil leab groove center axis all adopt with the piston body shaft axis and are provided with in vertical direction, the piston pin hole oil leab is obstructed by the through hole top, below that center one end is provided with from piston pin hole inwall and piston axes line parallel direction, the unlubricated oil channel hole of most pistons.When motor or air compressor quit work, having hit the lubricant oil that splashes in oil leab hole or the oil leab groove all is back in the oil sump through the piston body internal face within a short period of time, pilot engine once more or air compressor when work, lubricant oil in oil sump is not hit to be spattered when flowing into oil leab hole or oil leab groove, there is not lubricant film to form between piston body and the cylinder sleeve, cause the dry friction between piston body oil ring and the cylinder sleeve, not only starting effort, and increased parts wear, reduce mechanical working life.The above-mentioned technical problem low working environment of temperature in the winter time reflects particularly outstanding down; because within a short period of time; being in thick lubricant oil under the low temperature in the oil sump needs to heat up; reduce the lubrication of bearing piston body and cylinder sleeve and piston shaft and wrist pin hole wall in the oil leab hole that just can splash to piston body after the stickiness or the oil leab groove; so more aggravate parts wear in the starting process; starting time is long, the starting effort.For solving the problem that above-mentioned prior art exists, the applicant has studied a kind of engine piston with storing function, after the time-out running of motor short time, had piston when starting once more, the film lubrication function of oil ring and cylinder liner and piston shaft and wrist pin hole wall, dry grinding phenomenon when having eliminated starting, but defective is gone up in the original structure design, it is relatively poor that this piston stores the lubricant oil function, after motor quits work the long period, oilhole or oil leab groove inner bottom part trapped fuel slowly flow back in the engine sump tank from the gap of oil ring groove between piston body and cylinder liner on the piston body, during engine start, its piston shaft, piston, still be in the dry friction state between oil ring and the cylinder liner.
Summary of the invention
The purpose of this utility model with regard to the time problem that exists at above-mentioned prior art, design provides a kind of motor Oil preserving piston of being convenient to initial lubrication, makes it have the function that stores lubricant oil, reaches that to stop back initial lubrication performance in the engine long time service good.Start laborsavingly, reduce the component start-up wear, elongated component working life, reduce the purpose of user cost.
Basic design of the present utility model is, the motor Oil preserving piston of being convenient to initial lubrication comprises piston body and is arranged on compression, oilhole, oil ring groove, piston pin hole on the piston body, be positioned at oilhole or oil leab groove and oil ring groove bottom place in the piston body madial wall oil storage blind hole or oil storage circular groove be set, the upper end portion of this oil storage blind hole or oil storage circular groove and oilhole or oil leab groove and oil ring groove are connected.Oil storage blind hole or oil storage circular groove and oil storage segments in a circular shape groove are set below the outer side wall oil ring groove of piston, reach the oil storage function.
The utility model is in motor or air compressor quit work the back long period; in oil storage blind hole or oil storage circular groove, can there be lubricating oil; when motor or air compressor are reset; the oil sump inner engine oil do not hit spatter be injected in the piston body oilhole before; promptly realized the lubrication between piston body and the cylinder sleeve; it is good to have shutdown back initial lubrication performance rational in infrastructure, long-time; start laborsaving, the component start-up wear is few; help elongated component working life, reduce the characteristics of user cost.

Embodiment
Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.A kind of motor Oil preserving piston of being convenient to initial lubrication, comprise piston body 1 and be arranged on compression 2, oilhole 3, oil ring groove 4, piston pin hole 6 on the piston body 1, be positioned at oilhole 3 and oil ring groove 4 bottoms place in piston body 1 madial wall oil storage blind hole or oil storage circular groove 5 are set, the upper end portion of this oil storage blind hole or oil storage circular groove 5 is connected with oilhole 3 and oil ring groove 4.When motor or air compressor work, the lubricant oil in the oil sump is hit continuously to be spattered in the oilhole 3 that is injected into piston body 1, and forms oil film between oil ring groove 4 inflow piston bodies 1 and cylinder sleeve, finishes lubrication operation.When motor or air compressor work stopped, the parts of lubricating oil that entered in the oilhole 3 can be stored in oil storage blind hole or the oil storage circular groove 5 for a long time, do not leak, for initial lubrication provides lube stock.When motor or air compressor start to work, the lubricant oil that stores in oil storage blind hole or the oil storage circular groove 5, sent into or suck oil ring and piston by inertial oscillation, constitute lubricant film between oil ring and the cylinder liner, short time dry friction when having avoided between piston, oil piston ring and the cylinder liner of motor or air compressor starting enters normal lubricating status subsequently.
