The model utility content
The utility model provides a kind of motorcycle O RunddichtringO high abrasion chain, it mainly is to solve the existing in prior technology roller chain in use, dust can enter between sleeve and the bearing pin, thereby make the friction between sleeve and the bearing pin aggravate, the wearing and tearing of bearing pin are comparatively serious, thereby cause short etc. technical problem of life-span of chain.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Motorcycle O RunddichtringO high abrasion chain of the present utility model, comprise the inner plate (1) more than 2 pairs, it is characterized in that described inner plate is the figure of eight, symmetrical cross-under has two bearing pins between every pair of inner plate, going back cross-under on the bearing pin has outer plate to be connected with adjacent a pair of inner plate, outer plate is located at the outside of inner plate, and be provided with the O RunddichtringO between inner plate and the outer plate, the O RunddichtringO is socketed on the bearing pin, the bearing pin of the end of Conveying chains is connected with the connection carrier bar, the outer end cross-under that connects carrier bar has the connection bearing pin, and the end that connects bearing pin is provided with cotter pin.Inner plate and outer plate are crisscross arranged, and leave the gap between inner plate and the outer plate, make things convenient for the O RunddichtringO to be connected between inner plate and the outer plate like this.Connecting bearing pin can be connected the whole piece chain with other device.The cotter pin that connects end, bearing pin outer end is connected to the outside that connects carrier bar, prevents to connect carrier bar and deviates to connect bearing pin.The whole piece chain needs to clean up earlier before going out finished product, carries out antirust processing again.
As preferably, be provided with sleeve between described inner plate and the bearing pin, the O RunddichtringO is socketed in the outer surface of sleeve.Sleeve can prevent that inner plate from producing friction when work and between the bearing pin, thus the wearing and tearing bearing pin.
As preferably, the outer surface of described sleeve is socketed with roller, convenient for assembly behind the motorcycle other component can on roller, roll.
As preferably, the material of described inner plate, bearing pin, outer plate, connection carrier bar is steel, and the intensity of inner plate, bearing pin, outer plate, connection carrier bar is stronger like this.Inner plate, outer plate, connection carrier bar can be that the 40Mn steel is made, and bearing pin can be that the 20CrMnTi steel is made.
As preferably, the end of described bearing pin is provided with the flange that can prevent that outer plate from deviating from.
Therefore, the utility model is provided with the O RunddichtringO between inner plate and outer plate, can prevent that inner plate and outer plate are in contact with one another wearing and tearing on the one hand, can prevent that on the other hand dust from can enter between sleeve and the bearing pin, thereby avoided the friction aggravation between sleeve and the bearing pin, reduced the wearing and tearing of bearing pin, the working life of chain is longer, and is simple and reasonable for structure.
