Description
Technical field
The invention belongs to the marine engine technical field, especially relate to a kind of Assembly of pin and processing method of marine engine Transmitted chains.
Background technique
Motor is the major impetus that ship advances, and it has advantages such as thermal efficiency height, good economy performance and starting are easy, is widely used at present.The output of the power of motor generally mostly is to export by Transmitted chains, Transmitted chains is assembled by some pitch chain joints, mostly this chain link generally is to comprise inner plate, outer plate, bearing pin, lining and roller, roller sleeve is on lining, lining is enclosed within on the bearing pin, traditional chain link its between roller and lining, be added with lubricant oil between lining and the bearing pin respectively, it can prevent from wearing and tearing between roller and the lining, and the wearing and tearing between lining and the bearing pin, this scheme can satisfy usage requirement to a certain extent, but the Transmitted chains of this structure is after long-time the use, because oil storage poor-performing, cause lubrication effect undesirable, be easy to generate stuck or locking phenomenon, shortened the working life of Transmitted chains, but also can produce bigger noise; In addition, because the lubrication effect difference causes friction factor to become big, shortened the working life of Transmitted chains; Secondly, get rusty easily, destroy the normal use of Transmitted chains, in addition, the Transmitted chains of this structure needs regular maintenance, has increased user cost virtually.
For this reason, people have carried out long-term exploration, have proposed various solutions.For example, Chinese patent literature discloses a kind of oil-free chain [application number: 97207026.5], by connecting the chain link that carrier bar, bearing pin, roller etc. constitute chain, bearing pin injects in the roller, in the both sides of roller the connection carrier bar is housed, it is characterized in that roller is built-in with a sleeve, the heterogeneous lubriation material of one deck is set between sleeve and the roller.In addition, Chinese patent literature discloses a kind of stagnant oil film and has covered formula chain [application number: 97240678.6], mainly is made up of pin, pin carrier bar, lining, roller and roller link plates.Feature is to be abound with on the inside and outside circumference of lining and roller to be provided with stagnant oilhole.Also have, Chinese patent literature also discloses a kind of chain [application number: 200420081887.3], is made up of chain section.Outer plate, bearing pin, sleeve and cylinder in chain link divides.Be shaped on the composite self-lubricating layer on said sleeve and the cylinder.
Above-mentioned several schemes are all to be to have improved existing Transmitted chains oil storage poor-performing to a certain extent, problems such as lubrication effect is relatively poor, but several schemes of above-mentioned this all fail fundamentally to solve existing Transmitted chains oil storage poor-performing, lubrication effect is relatively poor, and problems such as leakage of oil cause the friction factor between each component bigger, shortened the working life of Transmitted chains greatly, but also get rusty easily, cause satisfying usage requirement, be difficult for being applied.
