Problems solved by technology

[0002] The currently used elastic piston ring is prone to uneven force. Once the uneven force occurs, the cylinder liner will form an oval shape, which will cause air leakage. The elastic piston ring will also wear out with use, and the worn piston will There will be a gap between the ring and the cylinder liner, and it is more prone to air leakage.

Embodiment Construction

[0013] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment includes three sections of magnetic sections 1, all of which are 120-degree arcs with the same radius, so that the three magnetic sections 1 form a complete ring, and the two ends of the magnetic section 1 are provided with The groove-shaped hasp 2 extending from the two ends of the section 1, the opening direction of the groove at both ends is opposite up and down, so as to ensure the sealing of the joints of the three magnetic sections 1.

[0014] The present invention is composed of three magnetic joints 1, the outer diameter of each joint ring is one-third of the inner diameter of the cylinder liner, and the two ends of each magnetic joint 1 are provided with buckles 2 which overlap by one-third, so that the whole ring forms a three-dimensional One-half of the overlap, the overlap of the buckle 2 is the same pole, the surface of the ring is electroplated with chrome or co...

Abstract

The invention discloses a piston ring, in particular to a joint type magnetic piston ring. The joint type magnetic piston ring comprises a magnetic joint, which is characterized in that the magnetic joint comprises three sections of 120-degree arc, the radii of the three arcs are the same, and the magnetism at the contacted positions of the three arcs is the same. The invention has the beneficial effects that the bonding property of a magnet and a cylinder sleeve is good and is more uniform than that of an elastic single opening ring, therefore the cylinder sleeve is not easy to form an ellipse; after the wear of the ring and the cylinder sleeve, overlapped parts can automatically extend to fill wearing capacity, and no opening wakening air leakage exists, thereby improving the tightness, ensuring uneasy aging of lubricating oil, prolonging the service life of machine parts and improving the efficiency of heat engines.

Description

(1) Technical field [0001] The invention relates to a piston ring, in particular to a segmented magnetic piston ring. (2) Background technology [0002] The currently used elastic piston ring is prone to uneven force. Once the uneven force occurs, the cylinder liner will form an oval shape, which will cause air leakage. The elastic piston ring will also wear out with use, and the worn piston will There will be a gap between the ring and the cylinder liner, and it is more prone to air leakage. (3) Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the invention provides an easy-to-use segmented magnetic piston ring. [0004] The present invention is achieved through the following technical solutions: [0005] A section-type magnetic piston ring, including a magnetic section, is characterized in that: the magnetic section is three sections of 120-degree arcs, the three sections of arcs have the same radius, and the magnetic fields...
