Abstract
The utility model relates to a sealed piston ring of a dynamic internal combustion engine for traffic and transportation. The utility model is composed of a piston ring and notches, wherein, the piston ring is in a helical shape, a frame bar section material is rolled into two integral rings which are larger than 360 DEG, and the notches are arranged on helical ring heads and tail ends. The utility model having reasonable structure overcomes the problems of the existing piston ring having notches which are smaller than 360 DEG with seams and no node, etc. The utility model has the advantages of favorable sealing performance, no air leakage, round cylinder sleeve, no floating oil, no carbon deposit, high engine power, energy saving, standard exhaust emission, low abrasion, long service life, etc.
Description
Technical field: the utility model relates to a kind of sealed piston ring of communications and transportation power explosive motor.
Background technique: at present, seal ring on the explosive motor piston adopts both at home and abroad all is otch tensioner ring less than 360 °, this ring structure is unreasonable, causes the cylinder sleeve mill oval, along with the wearing and tearing mill of cylinder sleeve is big, gas leakage easily, carbon distribution, lubricating oil carry-over, therefore will cause engine power to reduce, and waste energy, exhaust emissions exceeds standard, and barrel wear is fast, and the general overhaul cycle shortens.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of spiral piston ring is provided, and it is fast to have solved barrel wear, problems such as gas leakage easily, carbon distribution, lubricating oil carry-over.The purpose of this utility model is achieved in that it is made of piston ring and gap.Piston ring is a screw type, is integral with moulding section bar circumvolution two loops, and it encircles greater than 360 °, at whorl head and tail end place gap is arranged.This product structure is reasonable, has overcome existing piston ring and has not beaten less than 360 ° of otch and connect, and the problem of seam is arranged.It has good airproof performance, air tight, cylinder sleeve rounding, does not scurry oil, carbon distribution not, and engine power increases, energy saving, and exhaust emissions is up to standard, reduces wear advantages such as long service life.
