Abstract
A wear resistant piston ring, relates to the structural technic of piston ring. The cylindrical face of the ring-shaped main body is provided with a ceramic granule reinforcement composite coating. The utility model will not be peeled off or stripped off under the action of external force, and is favorable to store oil and keep the continuity of the lubricant film. The structure enhances the surface hardness of piston ring markedly and decreases the friction coefficient, and has very good abilities of grain-abrasion resistance and adhesive abrasion resistance. Determined by friction wear test and engine rig test, the piston ring always shows excellent friction wear characteristic when matching with cylinder sleeves of different materials: small friction coefficient and sharply decreased wearing capacity of both the ring and the sleeve. Thereby the utility model has the superiority of extending the service life of piston ring and enhancing the stability of production technology.
Description
Technical field
The utility model relates to the structure technology of piston ring.
Background technique
Usually piston ring is made annular body by steel or iron casting, grinding, heat treatment, grinding; because piston ring in use, its periphery is a frictional contact surface, Gu often find distortion because of friction causes piston ring; even rupture, sealing is subjected to direct influence.
The model utility content
The utility model purpose is exactly for improving the wear-resisting type piston ring of piston ring bulk life time, product technology good stability.
The utility model is provided with ceramic particle enhancing composite coating at the periphery of annular body.
The utility model can not come off or peel off under external force, help oil storage and keep the lubricant film continuity, this structure has significantly improved the surface hardness of piston ring and has reduced friction factor, has very strong wear-resistant grain wearing and tearing and antisticking wearing and tearing ability concurrently.Frictional wear experiment and engine rig test prove that this piston ring has all demonstrated excellent friction and wear characteristic when joining pair with the unlike material cylinder liner: the remarkable reduction of low coefficient of friction and ring, cover both sides wear extent.So, the utlity model has the superiority that improves piston ring working life, product technology good stability.
The Vickers hardness that the utility model ceramic particle strengthens composite coating is HV850～1200.Its wear resistance is stronger.
The thickness that above-mentioned ceramic particle strengthens composite coating can be 0.08～0.60mm.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
As shown in the figure, it can be the ceramic particle enhancing composite coating 2 of HV850～1200 for 0.08～0.60mm, Vickers hardness that the periphery of the cast-iron piston ring-type main body 1 that will obtain behind rough-cast, grinding end face, heat treatment, machining both ends of the surface, the rough turn cylindrical of profiling adopts the compound layer thickness of laser method, and then with semi-finished product through heat treatment, milling mouth, rough bore, slightly repair mouth, cylindrical grinding, right boring hole, refine mouth, phosphatization, oil, form final piston ring.
Claims (3)
1, the wear-resisting type piston ring comprises annular body, it is characterized in that at the periphery of annular body ceramic particle enhancing composite coating being set.
2,, it is characterized in that the Vickers hardness of described ceramic particle enhancing composite coating is HV850～1200 according to the described wear-resisting type piston ring of claim 1.
3,, it is characterized in that the thickness of ceramic particle enhancing composite coating is 0.08～0.60mm according to claim 1 or 2 described wear-resisting type piston rings.
