Abstract

The utility model discloses the special-purpose thin wall cylinder cover of a kind of high-strength natural gas motor, described cylinder liner body is hollow cylindrical tube structure, on its internal surface, through hone, process reticulate pattern at 45 °, described cylinder liner is that chromium molybdenum copper alloy cast iron is made, and is fine pearlite structure in it.The utility model changes cylinder liner Tensile strength, surface treatment hardness, surperficial hone reticulate pattern angle, reticulate pattern distributed quantity and the reticulate pattern degree of depth by raising, strengthens bulk strength and the wear-resisting property of cylinder liner; The utlity model has simple in structure, stable performance and working life longer advantage.

Description

The special-purpose thin wall cylinder cover of a kind of high-strength natural gas motor
Technical field
The utility model relates to the special-purpose thin wall cylinder cover of a kind of high-strength natural gas motor.
Background technique
The cylinder liner of natural gas engine is as an important spare part of motor moving system, and its friction factor has determined the power moment of torsion output of motor, and wear resistance has determined operational safety and the life-span of motor.Therefore cylinder liner plays vital effect to the normal operation of motor, and current cylinder liner intensity and toughness are poor, in use often damages.
Model utility content
The purpose of this utility model provides a kind of high-strength natural gas motor special-purpose thin wall cylinder cover with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
Cylinder liner body described in the utility model is hollow cylindrical tube structure, on its internal surface, through hone, process reticulate pattern at 45 °, described cylinder liner body is that chromium molybdenum copper alloy cast iron is made, and the graphite of its friction surface be take A type as main, its matrix fine pearlite structure.
Particularly, the hardness of described cylinder liner is 240～300HB, and tensile strength is greater than 320MPa.
As preferably, described hone textured surface requires:
Tp1=60%～80% (Ref=5%), sk=-0.8～3 are when sample length L=4mm, and the groove number of the degree of depth >=4um is no less than 5, and the angle of cut of reticulate pattern is 45 ° ± 10 °, Rz=5～7, reticulate pattern should be clear, clean, on both direction, is uniformly distributed.
The beneficial effects of the utility model are:
The utility model changes cylinder liner Tensile strength, surface treatment hardness by raising, strengthens bulk strength and the wear-resisting property of cylinder liner; The utlity model has simple in structure, stable performance and working life longer advantage.
Accompanying drawing explanation
Fig. 1 is the axial sectional view of the special-purpose thin wall cylinder cover of a kind of high-strength natural gas motor described in the utility model.
In figure: 1-cylinder liner body, 2-hone reticulate pattern.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, cylinder liner body described in the utility model is cylindrical tube 1 structure, on its internal surface, through hone, process reticulate pattern 2 at 45 °, described cylinder liner body 1 is made for chromium molybdenum copper alloy cast iron material, it in it, is fine pearlite structure, the hardness of described cylinder liner body 1 is 240～300HB, and tensile strength is >=320MPa.
Those skilled in the art do not depart from essence of the present utility model and spirit, can there is various deformation scheme to realize the utility model, the foregoing is only the better feasible embodiment of the utility model, not thereby limit to interest field of the present utility model, the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes, within being all contained in interest field of the present utility model.
