Conjoined elastic multi-circle piston ring and installation method thereof

Abstract

Disclosed is a conjoined elastic multi-circle piston ring. The conjoined elastic piston ring comprises a cylindrical tension spring structure of at least two circles. The conjoined elastic multi-circle piston ring has the advantages that analyses, comparisons, studies and tests prove that opening air leakage and end gap air leakage losses, non-uniform abrasions of air cylinder walls, heat dissipation capabilities, vibration noises and engine oil pollution of traditional opened single-circle piston rings can be improved by the conjoined elastic multi-circle piston ring, so that the whole machine performance maintenance quantity can be greatly improved, and the service life can be greatly prolonged; the ring is also applicable to sealing of various compression air cylinder pistons and is free of opening gaps, good in airtightness, uniform in tension, small in damage to a cylinder body, long in service life and beneficial to improvement of performance indexes.

Description

technical field [0001] The invention relates to the technical field of cylinder piston ring supplies, in particular to a one-piece elastic multi-circle piston ring and an installation method thereof. Background technique [0002] Various existing cylinders need to consider the reasons of thermal expansion and cylinder wall tension, and the various piston rings used for sealing are non-circular single-circle rings with opening gaps and free states. [0003] Due to the above-mentioned single-ring piston ring, the opening gap and the non-uniform tension against the cylinder wall, the end clearance cannot be zero, and the sealed cylinder and piston ring are both in a non-circular wear state. What kind of adverse consequences piston rings have on engine performance and life, the existing research on piston rings has failed to escape this fundamental defect. Contents of the invention [0004] The purpose of the present invention is to design a one-piece elastic multi-circle pis...
