Abstract
The utility model relates to a piston ring for a power machine, which is mainly composed of a ring body with an opening. The utility model has the characteristics that a U-shaped groove is arranged on one end part of the opening of the ring body, the other end part is provided with a sloping block corresponding to the U-shaped groove, the U-shaped groove and the sloping block are overlapped and tightly matched, and the service life of the piston ring is effectively improved. The utility model has the advantages of tight sealing and simple structure.
Description
The utility model relates to a kind of reciprocating engine piston ring, particularly a kind of power engine piston ring that has improved piston ring joint.
The used piston ring of power engine all has certain working clearance, the generation of the cylinder phenomenon that rises when preventing thermal expansion now.Owing to ring to-and-fro motion in cylinder, after use a period of time, owing to wearing and tearing, at opening the working clearance increase will appear, cause disappointing, gas leakage, influence the power performance of diesel engine, what formation encircled scraps.For improving the working life of piston ring.Opening now also having occurred is the piston ring of concave-convex shape overlap joint, projection and recess are positive right angle, realize because the sealing of piston ring is the anti-counterpressure that relies on the power engine burst period to form, and can form straight-through equally, cause piston ring to lose heart and gas leakage, the early stage guarantor of piston ring given up.
The purpose of this utility model is to provide the lap jointing type power engine piston ring of a kind of long service life, good seal.
The utility model is achieved in that
A kind of power engine piston ring mainly is made up of the ring body of band opening, and it is characterized in that: an end at above-mentioned ring body opening is provided with a U-shaped groove; The other end is provided with and the corresponding skewback of above-mentioned groove.
After the utility model adopts above structure, because gap-clearance of piston rings is designed to the abnormity overlap joint to be cooperated, kept in the power engine outburst process formation at the anti-counterpressure of oral area, can safeguard the correct sealing state of ring body opening effectively, improve the sealability of piston ring, have simple in structure, easily manufactured, good seal, undismayed effect, particularly mounting process is good, is fit to the production line assembling.Owing to wear and tear when increasing, still can keep good sealing state when opened gap, prolong piston ring 2-3 in working life doubly.
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the sectional drawing of opening shown in Figure 1;
Fig. 3 is the front view of opening shown in Figure 1;
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
In the accompanying drawing, 1 is that ring body, 2 is that groove, 3 is skewback.
As shown in Figure 1, 2, 3, the utility model is a kind of power engine piston ring, mainly is made up of the ring body 1 of band opening, is provided with the groove 2 of a U-shaped in an end of opening, accepts anti-counterpressure; The other end is provided with the skewback 3 corresponding with groove 2, makes the two overlap joint that fits like a glove, and keeps the height and the thickness of former piston ring, put into behind the cylinder body ring body 1 form one 360 ° just round.The cross section of U-shaped groove is designed to rectangle or trapezoidal.
The underpart, longitudinal section of above-mentioned U-shaped groove is rectangle or square, and the upper end portion is a circular arc.
Claims (2)
1. a power engine piston ring mainly is made up of the ring body (1) of band opening, and it is characterized in that: an end at above-mentioned ring body (1) opening is provided with a U-shaped groove (2); The other end is provided with and the corresponding skewback of above-mentioned groove (2) (3).
