Supporting device used for piston ring

Abstract

The invention discloses a supporting device used for a piston ring. The supporting device comprises a supporting ring. A ring-shaped groove used in cooperation with the piston ring is formed in the surface of the supporting ring. The supporting ring comprises a base layer, and an anti-corrosion layer is fixedly connected to the outer wall of the base layer. A high-temperature-resisting layer is fixedly connected to the outer wall of the anti-corrosion layer. A strengthening layer is fixedly connected to the outer wall of the high-temperature-resisting layer. A wear-resisting layer is fixedly connected to the outer wall of the strengthening layer. By means of the supporting device used for the piston ring, due to the cooperative use of the supporting ring, the ring-shaped groove, the base layer, the anti-corrosion layer, the high-temperature-resisting layer, the strengthening layer and the wear-resisting layer, the piston ring and the supporting device can be cooperatively used to be installed on a piston, smooth reciprocating motion of the piston in an air cylinder is strengthened, the problem that the piston ring is used frequently for a long term, and the surface of the piston ring is worn is reduced, the friction coefficient between the piston ring and the piston is greatly reduced, the service life of the piston ring is prolonged, the supporting performance of the piston ring is better, and the service life of the supporting device is prolonged.

Description

technical field [0001] The invention relates to the technical field of piston rings, in particular to a supporting device for piston rings. Background technique [0002] Piston ring is a metal ring used to embed in the piston groove. It is the core component inside the fuel engine. It completes the sealing of fuel gas together with the cylinder, piston, and cylinder wall. Piston rings are divided into two types, compression rings and oil rings. , the compression ring is used to seal the combustible gas mixture inside the combustion chamber, and the oil ring is used to scrape off excess oil on the cylinder. The functions of the piston ring include sealing, regulating oil, heat conduction, and guiding. It must have excellent wear resistance And the low wear performance of the cylinder liner to prolong the service life of the engine and reduce maintenance costs. When the engine is working, there are gas pressure, its own elasticity, inertial force of repeated movement, and fric...
