Abstract
The utility model relates to a spiral pipe type oil-penetrating lubricating structure for an engine cylinder. A cylinder pipe of which the outer surface is provided with a spiral ring groove is sheathed in the inner hole of a cylinder. The bottom of the spiral ring groove is provided with through holes which are arranged at intervals. A hollow oil pipe is wound in the spiral ring groove, and the surface of the oil pipe is provided with an oil-penetrating hole. An oil inlet pipe enters from the outside of the outer wall of the cylinder and is communicated with an oil outlet pipe. The lower end of the cylinder is combined with a body. The end face part of the body is provided with an inner concave oil collecting ring. The oil outlet pipe is connected to the oil collecting ring. When lubricating oil flows into the oil pipe wound in the spiral ring groove from the oil inlet pipe, the lubricating oil penetrates into the spiral ring groove from the oil-penetrating hole on the surface of the oil pipe, and then uniformly penetrates into the inner surface of the cylinder in omnidirection from the through holes arranged at the bottom of the spiral ring groove to have uniform lubrication, while lubricating oil which flows downwards flows into the oil collecting ring together and is exhausted.
Description
The utility model relates to a kind of lubricating fitting, particularly a kind of spiral-type oil-penetrating lubricating structure that is applied in engine cylinder.
Lubricated between present engine cylinder and the interior reciprocating motion stops thereof is to rely on the mode of adding machine oil in the fuel oil to carry out.Though it has saved special-purpose lubricating oil path and device, the structure of cylinder is simplified to some extent, but its exist greatest problem be pollute more serious, its reason just is that the part fuel molecule can be cladded by blending machine oil molecule therein before unburned, thereby, cladded fuel molecule can't obtain perfect combustion, so caused the waste and the air pollution problems inherent of the energy.In addition, because machine oil and the structure of molecule of fuel oil and the incomplete intermiscibility between the performance make lubrication effect undesirable, promptly can not form uniform lubricant film.
For addressing this problem, a kind of lubricating structure of engine cylinder is disclosed in our No. 89106749 patents formerly, the main feature of this lubricating structure is, there is not two-phase spaced-apart ring-shaped groove at the cylinder body internal face, in two annular grooves, embed the middle dry pipe that two annulars are arranged, oil pipe only offers oil seepage hole, and then two annular oily nets are inserted oil pipe outside in the annular groove, promptly is seated in the interior ring diameter side of fuel ring pipe.Its working principle is, lubricated machine oil is flowed into by the oil pipe in first annular groove and is exuded to annular oily net and then permeates away through the oil net through himself oil seepage hole, the lubricant oil that permeates away flows under the influence of gravity into the oil net place of second circular groove, at last by oily net endosmosis in oil pipe, so the lubricated of cylinder inner wall carried out in circulation, and machine oil can not sneaked in the fuel oil yet in greasing, promotes purpose lubricated and that minimizing is polluted to reach.Yet this lubricating structure exists following problem letter to be solved in actual use.First: because oil pipe and oily net all are that inlay card is within annular groove, and have only very little gap movingly between outside piston and the cylinder inner wall and the inner ring surface of annular oil net must embed in the annular groove fully or concordant with cylinder bore otherwise, will increase the resistance of piston even can produce the blocked portion phenomenon, because the inner ring surface that will make annular oil net all the time can be concordant with cylinder face is unlikely.In addition, because of its lubricant oil can only be supplied with by the oil inlet pipe in first annular groove, and through with its another annular groove separately in oil pipe ooze out after recycling, the lubricated full surface of cylinder bores that can not make of this large-spacing all obtains the lubricated of uniformity, so thereby the oil film that can not form uniformity has also caused the decline of lubrication effect.
The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect that prior art is deposited, and provides a kind of cylinder surfaces that makes concordant and have the spiral-type oil-penetrating lubricating structure of the engine cylinder of omnibearing infiltration lubrication effect.
The purpose of this utility model is to realize by following technological scheme:
In the endoporus of cylinder, be set with the cylinder sleeve that an outer surface offers the spiral annular groove, the bottom of spiral annular groove offers the through hole that is provided with at interval, drum has hollow oil pipe in the spiral annular groove, the surface of oil pipe offers oil seepage hole, oil inlet pipe is introduced and is connected with oil inlet pipe from casing outer wall, the cylinder lower end combines with body, offer the oil collecting ring of an indent in the end face portion of body, the oil collecting ring place is connected with oil outlet tube, after lubricant oil flows in the oil pipe of drum in the spiral annular groove by oil inlet pipe, then the oil seepage hole by the oil pipe surface penetrates in the spiral annular groove, the open-work of being offered by the whorl groove bottom equably then, penetrate into cylinder face in all directions, to play uniform lubrication, dirty lubricant oil then is flowed to oil collecting ring and discharges.
Therefore: remarkable result of the present utility model is:
The the 1st: be inlaid in the spiral annular groove that the outer surface of cylinder sleeve offers because oil pipe is a drum, promptly any assembly relation does not take place in the internal surface with cylinder sleeve, thereby, can not exist and the not concordant problem of cylinder sleeve internal surface yet, so piston can move swimmingly along the cylinder sleeve endoporus.
The 2nd: owing to offer countless oil permeable holes uniformly at intervals on the cylinder sleeve, thereby the lubricant oil that is infiltrated by the outside can be comprehensive, equably seepage flow in the cylinder sleeve endoporus.So have splendid lubrication.
Concrete structure of the present utility model is realized by the following examples and accompanying drawing thereof:
Fig. 1 is a section of structure of the present utility model.
Fig. 2 is the construction profile figure of cylinder sleeve among Fig. 1.
Fig. 3 is the outline drawing that is coiled in oil pipe in the cylinder sleeve spiral annular groove among Fig. 1.
Below in conjunction with accompanying drawing 1-3 concrete structure of the present utility model is described in detail:
With cylinder 3 endoporus mutually the outer surface of the cylinder sleeve 1 of suit offer spiral annular groove 11, offer the oil permeable hole 12 that connects with its inwall in the bottom surface of spiral annular groove 11, drum is embedded with the oil pipe 2 that offers oil seepage hole 21 in spiral annular groove 11, join at the cylinder body 4 and the cover of cylinder sleeve 1 lower end on the cylinder body 4 of end and offer oil trap 51, on oil trap 51, locate to draw and be connected to oil outlet tube 32, the oil pipe 2 on cylinder sleeve 1 top of the suit perforation that is connected in oil inlet pipe 31 and the cylinder.Referring to Fig. 1 to Fig. 3
Structure characteristic of the present utility model also is:
Oil permeable hole 12 and oil seepage hole 21 all are uniform shape separately, flexible oil pipe 2 is axially coiled downwards by last from coil to coil along the recessed spiral annular groove 11 of cylinder sleeve 1 outer surface, oil trap 51 is opened in the upper-end surface of holding oil ring 5 of body 4 upper end hole place convexes and is the ring-type of indent, and the bore area lower end edge of cylinder sleeve 1 is positioned within the groove width of oil gathering from looped well groove 51 of indent.Referring to Fig. 1 to Fig. 3
Working principle of the present utility model is as follows: referring to Fig. 1: after lubricant oil flows in the oil pipe of drums in spiral annular groove 11 by oil inlet pipe 31, then by the oil seepage hole on oil pipe surface infiltrate in the spiral annular groove, the open-work 12 offered by the whorl groove bottom then penetrates into cylinder sleeve 3 internal surfaces equably, in all directions, to play uniform lubrication, dirty lubricant oil then is pooled to oil trap 51 and discharges.
