Description
Technical field
A kind of chain of engine is the utility model is related to, particularly a kind of tooth form chain structure.
Background technology
In order to ensure use intensity, existing tooth form chain structure is typically to be superimposed to use by polylith carrier bar, and then carrier bar passes through
Axis pin joint forming, forms clearance fit between carrier bar and axis pin, carrier bar internal surface of hole and axis pin outer surface directly contact, due to
Aperture and the hole heart are away from there are error during carrier bar punching press so that the carrier bar on same chain link cannot be contacted with axis pin surface at the same time, sternly
May only have indivedual carrier bars individually to bear load during weight, make the carrier bar elder generation wear out failure, influence the stress of remaining plate, so as to accelerate
The abrasion of chain, the service life of shortening chains.And carrier bar is directly connected to by axis pin, the precision of assembling is relatively low.Therefore, it is existing
Technology there is the problem of chain is easy to wear, service life is short and the assembly precision of chain is relatively low.
Utility model content
The purpose of this utility model is that, there is provided a kind of tooth form chain structure.The utility model have can increase chain
The characteristics of assembly precision of abrasivity, extension chain service life and raising chain.
The technical solution of the utility model：A kind of tooth form chain structure, including multigroup chain link connected through the first axis pin；It is described
Chain link include two pieces of outer guide plates being arranged side by side, the connection carrier bar being arranged side by side is equipped between two pieces of outer guide plates, connects carrier bar
Positioning carrier bar is equipped between every piece of outer guide plate, and positions and is arranged between carrier bar and outer guide plate for dislocation, the outer guide plate,
It is connected between positioning carrier bar and connection carrier bar through the second axis pin；The positioning carrier bar and connection carrier bar includes polylith through bushing
Connected carrier bar, the both ends of the carrier bar are equipped with pin hole, and bushing is located in pin hole, and bushing is interference fitted with pin hole.
In a kind of foregoing tooth form chain structure, the outer guide plate includes fence body, and fence body both ends are equipped with through hole.
In a kind of foregoing tooth form chain structure, the carrier bar includes carrier bar main body, and it is convex that carrier bar main body both ends are equipped with circular arc
Plate, the pin hole are located on circular arc protrusive board.
Compared with prior art, the utility model is in the pin hole of carrier bar by setting bushing, passes through bushing and pin hole
Interference fit realizes the purpose that polylith carrier bar is fixed together, so as to effectively improve same chain link intermediate plate by
The power uniformity, overcome due to produce error band unbalance stress the problem of, and then reduce carrier bar the degree of wear, extend chain
Plate service life, and installed again after polylith carrier bar is fixed, additionally it is possible to greatly improve the assembly precision of carrier bar.Together
When, since bushing uses cold upset forming, the roughness of inner surface is less than the roughness of the pin hole on carrier bar after punching press, so as to
The frictional resistance with axis pin surface is substantially reduced, mitigates abrasion, prolongs the service life.In conclusion the utility model has energy
The characteristics of enough increasing the abrasivity of chain, extending chain service life and improve the assembly precision of chain.
