The utility model is composed of a pin shaft of a conveying chain, and a sleeve barrel which is arranged on the exterior of the pin shaft. The exterior of the sleeve barrel is provided with a rolling wheel. The both ends of the pin shaft and the sleeve barrel are respectively provided with an outer chain board and an inner chain board. A spacer piece is additionally arranged between the rolling wheel and the inner chain plate. The inner hole of the rolling wheel is additionally provided with a rolling wheel lining sleeve. An outer circle of the sleeve barrel is additionally provided with a sleeve barrel lining sleeve. The sleeve barrel and the both ends of the cylindrical matching surface of the rolling wheel are also respectively and additionally provided with a sealing component and a sealing cover, and then a sealing device is formed. The utility model is suitable for conveying chains with large rollers, particularly the large rollers with wheel edges. The utility model has the enhancement function on the heat resistance performance and the corrosion resistance performance of the conveying chain, and mainly has the enhancement function on the wear resistance performance of the conveying chain.
Description
The utility model relates to a kind of new construction of conveyer chain, can strengthen the resistance to abrasion of conveyer chain.
Increasing the service life of chain, is the producer and user's questions of common interest.Under non-corrosive operating mode, be decided by the fatigue resistance and the resistance to abrasion of chain part the service life of messenger chain, wearing and tearing mainly are present in bearing pin cylindrical and sleeve endoporus, and wearing and tearing only cause when nibbling out sprocket wheel because of the chain overmask; Conveyer chain is much slower than messenger chain because of operating speed, only be decided by the resistance to abrasion of part service life, the abrading section is except that bearing pin cylindrical and sleeve endoporus, also have the wearing and tearing of bearing the load-bearing part of transported substance weight in the chain, and the wearing and tearing at other positions that cause because of conveying, and in the service life of conveyer chain, often depend mainly on the resistance to abrasion of supporting part and carry other position resistance to abrasions that cause.In addition, the wear problem of the guide rail of supporting conveyer chain supporting part also is when research strengthens the conveyer chain resistance to abrasion, must with respect to.
For the small roller conveyer chain of roller diameter less than the chain plate height, the worn-down supporting part is arranged often is carrier bar or be contained in annex on the carrier bar, is cliding friction between supporting part and guide rail.For the large roller conveyer chain of roller diameter greater than the chain plate height, it often is sleeve and roller (this renames as roller often) that the worn-down supporting part is arranged, and is friction of rolling between roller and guide rail, but with a small amount of cliding friction.
The utility model is intended to strengthen from structure the resistance to abrasion of large roller conveyer chain, increases the service life.The decisive factor of the friction durability of large roller conveyer chain, by the significance level order, be sleeve cylindrical resistance to abrasion successively, roller endoporus resistance to abrasion and inner plate medial surface resistance to abrasion, this three factor is all than friction durability of bearing pin external diameter and the wear-resisting more influence of manying of sleeve diameter chain.As for the wearing and tearing of inner plate medial surface, be by the play that rolls in the running, wheels side * face contact inner plate medial surface occurs and cause that this play is for the easier generation of the roller of belt wheel edge.The purpose that the utility model proposes is the resistance to abrasion that strengthens sleeve cylindrical, roller endoporus and the inner plate medial surface of conveyer chain from structure.
For achieving the above object, the technical solution of the utility model comprises following four contents.
The bearing pin outside of conveyer chain is provided with sleeve, and the sleeve outside is provided with roller, and bearing pin and sleeve two ends are respectively equipped with pin link plate and inner plate, establish distance piece between roller and inner plate.Roller endoporus edge is established roller bush.Sleeve cylindrical edge is established sleeve bushing.At the two ends of the cylindrical contact surface of roller and sleeve, the dynamic sealing device of being made up of sealing member and seal cover cap is set.
After adopting technical solutions of the utility model, compare, can obviously have following advantage and good effect with conveyer chain structure in the past.
1. the setting of distance piece in the time of can making roller that play is arranged, is exempted the wearing and tearing of roller end face to the inner plate inboard, not these wearing and tearing of reason and reducing gradually of the dangerous section that makes inner plate, intensity descends gradually, finally because of undercapacity ruptures, thus the service life of prolongation inner plate.
Set distance piece does not adopt any type of direct rigid attachment with the inner plate inboard, can avoid inner plate to have the strength degradation of additional stress or inner plate dangerous section at the rigid attachment place.For the conveyer chain of under the corrosive medium environment, working, no direct rigid attachment between distance piece and inner plate, can alleviate crevice corrosion, galvanic corrosion, differential concentration corrosion and the stress corrosion of inner plate inboard, thereby strengthen the corrosion stability of conveyer chain inner plate inboard, improve service life.
2. the setting of roller bush, the points hardness of roller endoporus was improved, the hardness of roller cylindrical is kept and the coupling of load-bearing guide rail surface hardness optimization, the wearing layer thickness of roller endoporus is increased, overcome and adopt the thick inadequately deficiency of surface treatment method hardened layer, thereby reach the effect of bigger enhancing roller endoporus friction durability.
For the conveyer chain of under corrosive medium, working, the operating mode that the roller endoporus is in corrosion and weares and teares and deposit and aggravate mutually, the setting of roller bush more helps adopting the local material method, and the material that solves roller endoporus and cylindrical requires to differ very different problem.
For big specification conveyer chain, the setting of roller bush can provide the more possibility of rebush realization roller endoporus reparation.
3. large roller conveyer chain, especially when roller belt wheel edge, the wearing and tearing of sleeve cylindrical are outstanding more serious than other positions, are to strengthen the conveyer chain key of friction durability, and are all the more so for the conveyer chain of working under corrosive medium.Because sleeve both had been subjected to the band of sprocket to impact engagement force, was subjected to bearing capacity again, so bulk strength of having relatively high expectations and dynamic ductility; From wearing and tearing, require higher surface strength and certain thickness wearing layer again; As corrosive medium is arranged again, unsuitable again surface carbon content height so homogenous material and treatment process will be fit to numerous and mutual contradictory requirement, is difficult to satisfactorily often attend to one thing and lose sight of another.Sleeve bushing is set, and utilization local material method just can have satisfactory result.
4. at the two ends of the cylindrical contact surface of roller and sleeve, sealing arrangement is set, for under dust atmosphere, working and carrying the conveyer chain of grit bulk cargo, especially abrasive particle is easy to enter the conveyer chain of sleeve and roller contact surface, as the bucket type elevator chain, be the resulting structure measure that strengthens the conveyer chain abrasive wear resistance.For except that require wear-resisting, also require heat-resisting and corrosion-resissatnt conveyer chain, the material of sealing member is selected and the fixing means of seal cover cap, should note when enforcement the utility model.
Below in conjunction with drawings and Examples the utility model is described in further detail.
