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 power system engine art.
Background technique
As everyone knows, cylinder piston mechanism is engine art, particularly the indispensable parts in motor car engine field.Because cylinder will keep sealability, so the piston in cylinder piston mechanism of the prior art 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 decline, so this is also that current motor manufacture cost is higher, the reason of rapid wear.
Summary of the invention
The object 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 object of the invention is to be achieved through the following technical solutions:
Wear-resistant guiding cylinder piston mechanism, comprise cylinder and piston, between described piston and cylinder, adopt little Spielpassung, make the space of 0.3-0.5mm between the inwall of cylinder and the outer wall of piston, outer surface at described piston is evenly provided with 3-5 the fin that leads longitudinally, described guiding fin is triangular in shape, and the width of all guiding fins and highly identical; Corresponding described guiding fin, relevant position on the inwall of described cylinder is provided with the guiding groove of equal number, described guiding groove is triangular in shape, the width of guiding groove is greater than the width of described guiding fin, the degree of depth of guiding groove equates with the height of described guiding fin, in the bottom of described guiding groove, is provided with oil groove.
Between described guiding fin and described piston, adopt embedded installation, and the fin of described 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 guiding groove, friction area is less, friction factor is little, so only need the lubricant oil of small amount also can make cylinder piston mechanism run well, so the large problem of frictional loss with regard to having avoided the contact friction of cylinder piston mechanism face to bring.Although still have a small amount of gas overflowing in non-contacting place, but do not hinder cylinder itself to work normally, do not hinder power output, even the cylinder piston mechanism of seal ring is housed, inevitably to have a small amount of air or fuel leakage too, as long as the air letting out and fuel oil are carried out reasonably collecting.And for the problem of gas overflowing, in the present invention, defined the space between cylinder and piston, do not affect the work of cylinder, and to overflowing the technical problem of gas collection, inventor will provide corresponding technological scheme in other relevant patent the insides and solve as far as possible.
Accompanying drawing explanation
According to drawings and embodiments the present invention is described in further detail below.
Fig. 1 is the structural drawing of the wear-resistant guiding cylinder piston mechanism described in the embodiment of the present invention.
Fig. 2 is the sectional view of piston in wear-resistant guiding cylinder piston mechanism;
Fig. 3 is the sectional view of cylinder in wear-resistant guiding cylinder piston mechanism;
Fig. 4 be in wear-resistant guiding cylinder piston mechanism after cylinder and Piston assembling at the partial enlarged drawing of guiding fin and guiding groove position.
Embodiment
As Figure 1-4, wear-resistant guiding cylinder piston mechanism described in the embodiment of the present invention, comprise cylinder 1 and piston 2, between described piston 1 and cylinder 2, adopt little Spielpassung, make the space of 0.3-0.5mm between the inwall of cylinder 1 and the outer wall of piston 2, outer surface at described piston 2 is evenly provided with 3-5 the fin 3 that leads longitudinally, and described guiding fin 3 is triangular in shape, and the width of all guiding fins 3 and highly identical; Corresponding described guiding fin 3, relevant position on the inwall of described cylinder 1 is provided with the guiding groove 4 of equal number, described guiding groove 4 is triangular in shape, the width of guiding groove 4 is greater than the width of described guiding fin 3, the degree of depth of guiding groove 4 equates with the height of described guiding fin 3, can guarantee like this to lead top of fin 3 and the bottom of guiding groove 4 carried out line contact and is connected, and in the bottom of described guiding groove 4, is provided with oil groove 5.
Between described guiding fin 3 and described piston 2, adopt embedded installation, and the fin of described 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 guiding groove, friction area is less, friction factor is little, so only need the lubricant oil of small amount also can make cylinder piston mechanism run well, so the large problem of frictional loss with regard to having avoided the contact friction of cylinder piston mechanism face to bring.Although still have a small amount of gas overflowing in non-contacting place, but do not hinder cylinder itself to work normally, do not hinder power output, even the cylinder piston mechanism of seal ring is housed, inevitably to have a small amount of air or fuel leakage too, as long as the air letting out and fuel oil are carried out reasonably collecting.And for the problem of gas overflowing, in the present invention, defined the space between cylinder and piston, do not affect the work of cylinder, and to overflowing the technical problem of gas collection, inventor will provide corresponding technological scheme in other relevant patent the insides and solve as far as possible.
