Cardan shaft for papermaking products,
The cardan shaft is broadly employed in the different kinds of paper creating equipments, like corrugated paper manufacturing tools, as nicely as computerized binding tools.Compared with cardan shaft for the rolling mill, the torque of the cardan shaft for the papermaking tools is smaller.Nonetheless, the dynamic equilibrium of the cardan shaft is really strict, because they need to have to run with higher velocity for a prolonged time.The organization specially produced the cardan shaft for such equipment with reduced servicing needs and longer upkeep intervals.Even in some parts of the tools, we have created a servicing totally free cardan shaft, so that the service life can achieve three many years, or even longer.
Who we are?
HangZhou EPT CARDANSHAFT COLTD has 15 a long time history.When the common supervisor Mr.Rony Du graduated from the university,he often concentrated his interest on the analysis and advancement,creation and revenue of the cardan shaft.Mr.Rony Du and his staff started out from scratch,from a single lathe and a quite tiny buy,phase by step to develop up.He typically explained to his staff”We will only do a single factor nicely——to make the ideal cardan shaft”.
General supervisor Mr.Rony Du
HangZhou EPT CARDANSHAFT CO.,LTD was founded in 2005.The registered capital is eight million ,handles an spot of 15 acres, has thirty current personnel. The organization specializing in the manufacturing of SWC, SWP cross universal coupling and drum tooth coupling.The organization with factory is found in the stunning coast of EPT Lake –Hudai (HangZhou Financial Improvement Zone Hudai Industrial Park).
In order to become China’s major cardan shaft one-quit remedy expert supplier . EPT CARDANSHAFT unbiased investigation and improvement of SWC light-weight, medium, quick, large Designs cardan shaft have arrived at the top domestic level.Products not only supporting domestic large and medium-sized consumers, but also exported to the United States, India, Vietnam, Laos, Ukraine, Russia, Germany, Britain and other nations around the world and places.In the past fifteen several years, the company has accrued a wealth of encounter, discover from international superior technology, and to soak up and use the universal axis has been improved a number of times, so that the framework is maturing, substantially improved overall performance.
EPT Workplace Constructing
EPT perception: “Steady innovation, enhance the structure, perseverance” to generate a higher quality of excellent cardan shaft producer.We often adhere to the ISO9001 good quality manage method, from the details to begin, standardize the generation procedure, and to attain processing equipment “specialization, numerical manage” speedy increase in item high quality.This Not only won the majority of consumers reputation, but also obtain to peer recognition. We carry on to strive to pursue: “for consumers to generate the finest value, for the workers to create the ideal system”, will be capable to achieve consumer and enterprise mutually beneficial EPT scenario.
Welcome to EPT CARDANSHAFT
Why choose us?
1st,select raw material cautiously
The cross is the core component of cardan shaft,so the choice of material is notably vital.Uncooked resources of the cross for mild Duty Dimension and Medium Obligation Dimensions,we decide on the 20CrMnTi particular equipment steel bar from SHAGANG Team.Being solid in 2500 ton friction push to make sure internal metallurgical framework,inspecting the geometric proportions of every part to fulfill the drawing demands,then transfer to machining,the procedures of milling, turning, quenching and grinding.
The inspector will screen blank yoke head.The porosity, cracks, slag, and so on. do not satisfy the needs of the casting foundry are all eradicated,then performing actual physical and chemical examination, to see whether or not the elements satisfy the needs, unqualified re-elimination.And then transferred to the quenching and tempering warmth treatment method, after again check out the hardness to see if meet up with the specifications, certified to be transferred to the machining method. We manage from the resource of the substance to make sure the source of raw supplies competent fee of ninety nine%.
Second,superior manufacturing gear
EPT Organization introduced four-axis linkage machining heart made in ZheJiang , milling the keyway and flange bolt hole of the flange yoke, The when equipment-shaping assures that the symmetry of the keyway and the situation of the bolt gap are considerably less than .02mm,which drastically improves the set up precision of the flange,the four axis milling and drilling center holes of the cross are integrated,to guarantee that the 4 shaft symmetry and verticality are significantly less than .02mm,the procedure of the journal cross assembly support life can be improved by 30%, and the pace at a thousand rpm previously mentioned the cardan shaft working efficiently and super lifestyle is essential to the procedure.
We use CNC machine to lathe flange yoke and welded yoke,CNC equipment can not only make certain the precision of the flange connection with the mouth, but also enhance the flange area end.
five meters automated welding device welding spline sleeve and tube,welded yoke and tube.With the welding torch swing system, automatic lifting system, adjustment mechanism and welding torch cooling method, welding machine can understand multi ring ongoing welding, each and every coil present and voltage can be preset, arc beginning and halting handle PLC methods, dependable welding good quality, the weld bead is clean and beautiful, to manage the welding procedure with fixed methods, tremendously decreasing the uncertainty of human in the course of welding, drastically improve the welding influence.
Large velocity cardan shaft demands to do dynamic stability check before leaving the factory.Unbalanced cardan shaft will generate abnormal centrifugal force at substantial velocity and lessen the services existence of the bearingthe dynamic harmony check can get rid of the uneven distribution of the casting weight and the mass distribution of the entire assemblyThrough the experiment to attain the layout of the necessary balance quality, improve the universal shaft service life.In 2008 the business launched two higher-precision dynamic balance examination bench, the optimum speed can attain 4000 rev / min, the harmony of G0.8 precision, equilibrium weight 2kg–1000kg.
In buy to make the paint standardization, in 2009 the company bought ten meters of thoroughly clean paint room , the floor treatment of cardan shaft is far more standardized, paint fastness is far more rugged, staff’s doing work situations enhanced, exhaust of harmless remedy.
Third,Professional transportation packaging
The packing of the export cardan shaft is all in the identical way as the plywood wooden box, and then it is firmly secured with the iron sheet, so as to keep away from the damage brought on by the complicated situation in the long-distance transportation. Meet up with the standard demands of plywood containers into Europe and other international locations, no make a difference in which can efficiently reach all the country’s ports.
