Abstract
The utility model discloses a platform honing reticulate pattern cylinder sleeve of a vertical type engine, wherein regular arranged and bidirectional crossed platform reticulate patterns are honed on the surface of the inner bore of a cylinder sleeve, and the inclined angle of the bidirectional crossed platform reticulate patterns on the direction of the central axis of the cylinder is 30-85 degrees. For the vertical type engine, lubricating oil stored in the inner surface of the honing reticulate pattern cylinder sleeve with acute angle reflows to the upper stopping position of a piston ring in the cylinder sleeve of the engine from the upper part and the middle part of the cylinder sleeve along grooves of the honing reticulate patterns due to the function of the gravity. Therefore, the reflowing path of the lubricating oil is greatly shortened, the reflowing speed of the lubricating oil is accelerated, the reflowing time of the lubricating oil to the upper stopping position of the piston ring in the cylinder sleeve is saved, the friction loss is reduced, and thereby, the consumption of the lubricating oil and the fuel oil by the engine is reduced.
Description
Technical field
The utility model relates to the air cylinder sleeve of engine technical field, a kind of especially vertical engine plateau honing cross hatches cylinder liner.
Background technique
At present, the honing platform reticulate pattern of domestic air cylinder sleeve of engine, reticulate pattern angle in the cylinder liner central axial direction all is the obtuse angle, this characteristics at cylinder liner central axial direction plateau honing cross hatches in obtuse angle are: when piston ring moves toward the lower dead center direction, blown into the lubricant oil of cylinder liner oil storage groove, flowed back to the lower dead center of air cylinder sleeve of engine along the groove of cross hatch from cylinder liner top.Because the cylinder liner reticulate pattern is the obtuse angle at the angle of central axial direction, cause the defective that the lubricant oil back-flow velocity is slow and the backflow distance is long.At this moment, the lubricant oil that stores in the interior surface of cylinder liner reticulate pattern groove is more, and the utilization ratio of lubricant oil is not high.Because the lubricant oil that stores in the cylinder liner oil storage groove often is in the state of buying securities with all one's capital, when piston ring is up again, scraping the lubricant oil that comes can't store, and will continue uply, might enter the firing chamber, and this danger that engine oil consumption increases may occur.
The model utility content
The utility model purpose is to provide a kind of vertical engine plateau honing cross hatches cylinder liner, can improve the utilization ratio of lubricant oil in the platform reticulate pattern, has also improved lubrication effect simultaneously.
To achieve these goals, the utility model adopts following technological scheme: a kind of vertical engine plateau honing cross hatches cylinder liner, honing goes out regularly arranged, bidirectional crossed platform reticulate pattern on cylinder jacket inner bore surface, and the angle of bidirectional crossed platform reticulate pattern on the cylinder liner central axial direction is 30 °～85 °.
Described cylinder liner is cast iron cylinder cover, steel cylinder liner, dry liner, wet liner.
The utility model is processed with plateau honing cross hatches at cylinder jacket inner bore surface, and it is netted regularly arranged that cross hatch is intersection, connects mutually between the groove of cross hatch, and the bi-directional platform cross hatch is 30 °～85 ° at cylinder cover inner hole central axial direction angle.The groove of cylinder liner cross hatch after being convenient to form lubricant film between piston ring excircle and the cylinder cover inner hole reticulate pattern platform, temporarily stores unnecessary lubricant oil, in order to avoid enter engine chamber.For vertical engine, this cross hatch cylinder liner that is acute angle, the lubricant oil that interior surface of cylinder liner stores, because the effect of gravity, will be along the cross hatch groove, on cylinder liner, the middle part flows back to air cylinder sleeve of engine piston ring bottom dead center position.Shorten the distance that lubricant oil refluxes greatly, increased the lubricant oil back-flow velocity, thereby saved the time of flow of lubricant return-air cylinder liner piston ring bottom dead center position.Have the lubrication effect that improves between piston ring and the cylinder liner friction pair, reduced frictional loss, thereby reduce lubricant oil, the fuel consumption of motor.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model plateau honing cross hatches.
Embodiment
Embodiment: as shown in Figure 1 and Figure 2, vertical engine plateau honing cross hatches cylinder liner, honing goes out regularly arranged, bidirectional crossed platform reticulate pattern 2,3 on cylinder liner 1 bore area, the included angle A of bidirectional crossed platform reticulate pattern on the cylinder liner central axial direction is 30 °～85 °, and cylinder liner 1 is cast iron cylinder cover, steel cylinder liner, dry liner, wet liner.
Flow back into the lubricant oil of cylinder liner piston ring lower dead center, accumulate on top piston ring and the circumference that interior surface of cylinder liner cooperates, this characteristic phenomenon more helps forming lubricant film between interior surface of cylinder liner and the piston ring face, has reduced frictional loss.Lubricant oil in the oil storage storehouse flows back to after the lower dead center, forms cavity in the oil storage storehouse.
When engine piston, connection rod set by lower dead center when top dead center moves, accumulate in the lubricant oil of top piston ring and interior surface of cylinder liner cooperation place, to between cylinder liner and piston ring two friction pair, form lubricant film, the friction surface between the friction pair will be lubricated.Form the unnecessary lubricant oil of lubricant film, will be stored in the cavity oil storage storehouse of cylinder liner reticulate pattern groove formation.
