Abstract
The invention relates to a cylinder sleeve with a spiral recess. Two sealed recesses (1) are arranged on the cylinder sleeve; two rows of scavenging holes (2) are arranged between the two sealed recesses (1); a spiral recess (3) is arranged on an outer wall of the cylinder sleeve; a cooling water chamber distributed in a single flowing direction is formed between each of the scavenging holes (2) on two ends of the spiral recess (3) and a gas exhaust hole (5); a water return hole (4) of the water chamber is arranged in the partitioned interior of the gas exhaust hole (5); and two ends of the cooling water chamber are respectively provided with tool withdrawal grooves (6). The cooling water is guided to flow along a single direction in such a way that the spiral recess is designed on the outer wall of the cylinder sleeve, thus bubbles generated in the water are reduced and caviation erosion generated on the cylinder sleeve is avoided; and the heat radiation area of the cylinder sleeve is increased, the cooling effect of the cylinder sleeve is enhanced, the cylinder sleeve has the effect of a reinforcing rib, the rigidity of the cylinder sleeve is enhanced, the deformation of the cylinder sleeve is controlled and the reliability of the reciprocating motion of a piston is assured.
Description
Technical field
The present invention relates to a kind of cylinder liner, be specifically related to a kind of cylinder liner that has helical groove.
Background technique
At present, cylinder liner mainly is divided into wet liner, dry liner and block-head cylinder cover.Raising along with the internal-combustion engine reinforcing degree, heat load also constantly increases, in order to strengthen its cooling capacity, what internal combustion engine use was more is wet liner, but there is following shortcoming in wet liner: the hot machine strength deficiency of cylinder liner, cause the distortion of cylinder liner wayward, defectives such as cavitation pitting take place in cylinder liner easily.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned deficiency, provides a kind of cylinder liner of avoiding to produce the cavitation pitting phenomenon, and the cylinder liner good cooling results can guarantee the cylinder liner that has helical groove of the reliability of reciprocating motion of the pistons.
Technological scheme of the present invention: a kind of cylinder liner that has helical groove, it comprises cylinder liner, it is characterized in that cylinder liner is provided with two sealed grooves, be provided with two above transfer ports between two sealed grooves, the outer wall of cylinder liner is provided with helical groove, be the cooling water chamber that the single flow direction distributes between the transfer port at helical groove two ends and the exhaust port, exhaust port cuts off the inner two ends that are provided with the backwater hole cooling water chamber of water cavity and is respectively arranged with tool withdrawal groove.
The present invention compared with prior art has following beneficial effect: at the outer wall design spiral chute of cylinder liner, guide cooling water flows along single direction, reduces the generation of underwater bubble, avoids cylinder liner to produce the cavitation pitting phenomenon; Increase the cylinder liner heat diffusion area, strengthen the cylinder liner cooling effect; Have the stiffening rib effect simultaneously, increase cylinder liner rigidity, the distortion of control cylinder cover, the reliability of assurance reciprocating motion of the pistons.
