Description
Technical field
The utility model relates to a kind of chain, particularly a kind of chain for dryer, redrying machine.
Background technology
In prior art, the chain of common blade dryer, redrying machine mostly is light-duty chain, and outer link and the inner link of chain are staggered installation of, and pin link plate is with widening bending or welding otic placode to connect oven dry web plate.Because web plate width dimensions can be more than or equal to 3m, the side pressure load that carrier bar bears is larger, and conventional chain is easily because sleeve and roller are subject to side pressure rapid wear, and it is even stuck to cause in operational process chain to tow, aggravation shortening chains service life.And conventional this chain hinge pin, sleeve are circle and coordinate with carrier bar circular hole.Bearing pin and sleeve in use for some time, easily, because wearing and tearing cause horizontal looseness, cause fluctuation of service, and de-chain fault even occurs, and have a strong impact on normal conveying.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of chain for dryer, redrying machine, its bearing pin, sleeve and carrier bar are difficult for producing relative motion, thereby reduce in the use procedure of chain, because relative motion causes undue wear, improve the service life of chain, ensured the safe and reliable operation of corresponding drive disk assembly.
The technical scheme that the utility model is taked is: a kind of chain for dryer, redrying machine, comprise the first carrier bar, the second carrier bar, described the second carrier bar is connected with otic placode, described the first carrier bar, the second carrier bar respectively interference are equipped with sleeve, described sleeve is provided with roller outward, roller and sleeve free-running fit, described the first carrier bar, the second carrier bar respectively interference are equipped with bearing pin.
The first carrier bar is arc type, and its bending part is provided with forging and stamping formula projection, and described the second carrier bar is Z-type, and the second carrier bar is combined with otic placode riveting by rivet.First carrier bar one end is provided with the flat hole, the other end that are connected with sleeve and is provided with and the circular hole of bearing pin force fit.The second carrier bar two ends are flat hole, comprise larger flat hole, less flat hole, and larger flat nose end is pressed into and coordinates with sleeve, and the flat horizontal of less flat nose end and bearing pin is pressed into joins work.
Described otic placode is bent into right angle, is respectively equipped with two of web plate assembly openings at two square edges, totally four assembly openings, and wherein two is slide opening.
Described the first carrier bar, the second carrier bar are pressed into and are connected by 0.1 ~ 0.15mm magnitude of interference with sleeve.
Described bearing pin one end is provided with pin.
A kind of chain for dryer, redrying machine of the utility model, the otic placode that connects oven dry web plate is bent into right angle, adopt riveting to be combined with carrier bar, increase the stability after chain side pressure load-carrying capacity and web plate assembling, on two square edges, respectively there is respectively the assembly opening of two fixed network boards, wherein two are designed to slide opening, are convenient to assembling.Carrier bar and bearing pin, sleeve are pressed respectively 0.1-0.15mm interference fit and are compressed, and can effectively prevent the wearing and tearing that relative motion produces, and have extended service life.
The utility model chain is rational in infrastructure, technique advanced person, and inside and outside carrier bar unites two into one, more convenient replacing assembling.
