Abstract
The invention discloses an abrasion-proof guide cylinder piston mechanism, which comprises a cylinder and a piston. The abrasion-proof guide cylinder piston mechanism is characterized in that: the piston is in small clearance fit with the cylinder; three to five longitudinal guide ribs are uniformly arranged on the outer surface of the piston, and are triangular; the widths and heights of all the guide ribs are the same; guide grooves in a number the same as that of the guide ribs are formed at positions opposite to the guide ribs on the inner wall of the cylinder, and are triangular; the widths of the guide grooves are greater than those of the guide ribs, and the depths of the guide grooves are equal to the heights of the guide ribs; and lubricating oil grooves are formed at the bottoms of the guide grooves. The abrasion-proof guide cylinder piston mechanism has the advantages that: the guide ribs and the guide grooves form linear contact friction with small friction areas and a low friction coefficient, so that the cylinder piston mechanism can normally run only by a small amount of lubricating oil, and the problem of high friction loss caused by the surface contact friction of the cylinder piston mechanism is solved.
Description
Technical field
The present invention relates to a kind of cylinder piston mechanism, belong to the power system engine art.
Background technique
As everyone knows, cylinder piston mechanism is an engine art, particularly the indispensable parts in motor car engine field.Because cylinder will keep sealability, so the piston in the cylinder piston of the prior art mechanism all can install 3-5 layer seal ring.Concerning piston; Processing technology is complicated, concerning cylinder, when piston is done fore and aft motion; Seal ring can repeatedly repeat friction with cylinder wall under the condition of high temperature; And under the condition of high temperature, the wear resistance of metal (even alloy) also can descend, so this also is that present motor manufacture cost is higher, the reason of rapid wear.
Summary of the invention
The objective of the invention is to solve the problem of existing cylinder piston mechanism rapid wear, a kind of wear-resistant guiding cylinder piston mechanism is provided.
The objective of the invention is to realize through following technological scheme:
Wear-resistant guiding cylinder piston mechanism; Comprise cylinder and piston; Adopt little Spielpassung between said piston and the cylinder, make the space of 0.3-0.5mm between the outer wall of inwall and piston of cylinder, evenly be provided with 3-5 the fin that leads longitudinally at the outer surface of said piston; Said guiding fin is triangular in shape, and the width of all guiding fins is identical with highly; Corresponding said guiding fin; Relevant position on the inwall of said cylinder is provided with the guiding groove of equal number; Said guiding groove is triangular in shape; The width of guiding groove is greater than the width of said guiding fin, and the degree of depth of guiding groove equates with the height of said guiding fin, is provided with oil groove in the bottom of said guiding groove.
Said guiding fin and the embedded installation of said piston by adopting, and the fin of said guiding fin surface adopts high-abrasive material one-body molded.
The invention has the beneficial effects as follows; Line contact friction between guiding fin and the guiding groove; Friction area is less; Friction factor is little, so only need more a spot of lubricant oil also can make the normal operation of cylinder piston mechanism, the big problem of frictional loss with regard to having avoided the face contact friction of cylinder piston mechanism to bring like this.Though still having little of gas in non-contacting place overflows; But do not hinder cylinder itself to work normally; Do not hinder power output; Even the cylinder piston mechanism of seal ring is housed, be that little air or fuel leakage are inevitably arranged too, as long as the air and the fuel oil that let out are reasonably collected.And the problem of overflowing to gas; Defined the space between cylinder and the piston among the present invention; Do not influence the work of cylinder, and to overflowing the technical problem that gas is collected, the inventor will provide the corresponding techniques scheme in other relevant patent the insides and solve as far as possible.

Embodiment
Shown in Fig. 1-4; The described wear-resistant guiding cylinder piston of embodiment of the invention mechanism comprises cylinder 1 and piston 2, adopts little Spielpassung between said piston 1 and the cylinder 2; Make the space of 0.3-0.5mm between the outer wall of inwall and piston 2 of cylinder 1; Evenly be provided with 3-5 the fin 3 that leads longitudinally at the outer surface of said piston 2, said guiding fin 3 is triangular in shape, and the width of all guiding fins 3 is identical with highly; Corresponding said guiding fin 3; Relevant position on the inwall of said cylinder 1 is provided with the guiding groove 4 of equal number; Said guiding groove 4 is triangular in shape, and the width of guiding groove 4 is greater than the width of said guiding fin 3, and the degree of depth of guiding groove 4 equates with the height of said guiding fin 3; Can guarantee like this to lead top of fin 3 is carried out the line contact with the bottom of guiding groove 4 and is connected, and is provided with oil groove 5 in the bottom of said guiding groove 4.
Adopt embedded installation between said guiding fin 3 and the said piston 2, and the fin of said guiding fin 3 surface adopts high-abrasive material 6 one-body molded.
The invention has the beneficial effects as follows; Line contact friction between guiding fin and the guiding groove; Friction area is less; Friction factor is little, so only need more a spot of lubricant oil also can make the normal operation of cylinder piston mechanism, the big problem of frictional loss with regard to having avoided the face contact friction of cylinder piston mechanism to bring like this.Though still having little of gas in non-contacting place overflows; But do not hinder cylinder itself to work normally; Do not hinder power output; Even the cylinder piston mechanism of seal ring is housed, be that little air or fuel leakage are inevitably arranged too, as long as the air and the fuel oil that let out are reasonably collected.And the problem of overflowing to gas; Defined the space between cylinder and the piston among the present invention; Do not influence the work of cylinder, and to overflowing the technical problem that gas is collected, the inventor will provide the corresponding techniques scheme in other relevant patent the insides and solve as far as possible.
