Product Description

Who we are?WUXI WEICHENG CARDANSHAFT CO;LTDhas 15 years history;When the general manager Mr;Rony Du graduated from the university;he always concentrated his attention on the research and development;production and sales of the cardan shaft;Mr;Rony Du and his team started from scratch;from one lathe and a very small order;step by step to grow up;He often said to his team ;We will only do one thing well——to make the perfect cardan shaft ;;WUXIWEICHENG CARDANSHAFT CO;;LTD was founded in 2005;The registered capitalis 8 million;covers an area of 15 acres; has 30 existing staff; The company specializing in the production of SWC; SWP cross universal coupling and drum tooth coupling;The company with factory is located in the beautiful coast of Tai Lake –Hudai (Wuxi Economic Development Zone HudaiIndustrial Park);In order to become China's leading cardan shaft one-stop solution expertsupplier ;WEICHENG CARDANSHAFT independent research and development of SWC light; medium; short; heavy Designs cardan shaft have reached the leading domestic level;Products not only supporting domestic large and medium-sized customers; but also exported to the United States; India; Vietnam; Laos; Ukraine; Russia; Germany; Britain and other countries and areas;In the past 15 years; the company has accumulated a wealth of experience; learn from foreign advanced technology; and to absorb and use the universal axis has been improved several times; so that the structure is maturing; significantly improved performance;WEICHENG belief; ;Continuous innovation; optimize the structure; perseverance ; to create a high quality of outstanding cardan shaft manufacturer;We always adhere to the ISO9001 quality control system; from the details to start; standardize the production process; and to achieve processing equipment ;specialization; numerical control ; rapid increase in product quality;This Not only won the majority of customers reputation; but also access to peer recognition; We continue to strive to pursue; ;for customers to create the greatest value;for the staff to build the best platform ;; will be able to achieve customer and business mutually beneficial win-win situation; Why choose us?First;select raw material carefullyThe cross is the core component of cardan shaft;so the selection of material is particularly critical;Raw materials of the cross for light Duty Size and Medium Duty Size;we choose the 20CrMnTi special gear steel bar from SHAGANG GROUP;Being forged in 2500 ton friction press to ensure internal metallurgical structure;inspecting the geometric dimensions of each part to meet the drawing requirements;then transfer to machining;the processes of milling; turning; quenching and grinding;The inspector will screenblank yokehead;The porosity; cracks; slag; etc; do not meet the requirements of the casting foundry are all eliminated;then doing physical and chemical analysis; to see whether the ingredients meet the requirements; unqualified re-elimination;And then transferred to the quenching and tempering heat treatment; once again check the hardness to see if meet the requirements; qualified to be transferred to the machining process; We control from the source of the material to ensure the supply of raw materials qualified rate of 99%;Second;advanced production equipmentWEICHENG Company introduced four-axis linkage machining center made in Taiwan; milling the keyway and flange bolt hole of the flange yoke; The once machine-shaping ensures that the symmetry of the keyway and the position of the bolt hole are less than 0;02mm;which greatly improves the installation accuracy of the flange;the four axis milling and drilling center holes of the cross are integrated;to ensure that the four shaft symmetry and verticality are less than 0;02mm;the process of the journal cross assembly service life can be increased by 30%; and the speed at 1000 rpm above the cardan shaft running smoothly and super life is crucial to the operation;We use CNC machine to lathe flange yoke and welded yoke;CNC machine can not only ensure the accuracy of the flange connection with the mouth; but also improve the flange surface finish;5 meters automatic welding machine welding spline sleeve and tube;welded yoke and tube;With the welding torch swing mechanism; automatic lifting mechanism; adjustment mechanism and welding torch cooling system; welding machine can realize multi ring continuous welding; each coil current and voltage can be preset; arc starting and stopping control PLC procedures; reliable welding quality; the weld bead is smooth and beautiful; to control the welding process with fixed procedures; greatly reducing the uncertainty of human during welding; greatly improve the welding effect;High speed cardan shaft needs to do dynamic balance test before leaving the factory;Unbalanced cardan shaft will produce excessive centrifugal force at high speed and reduce the service life of the bearing;the dynamic balance test can eliminate the uneven distribution of the casting weight and the mass distribution of the whole assembly;Through the experiment to achieve the design of the required balance quality; improve the universal shaft service life;In 2008 the company introduced two high-precision dynamic balance test bench; the maximum speed can reach 4000 rev ; min; the balance of G0;8 accuracy; balance weight 2kg–1000kg;In order to make the paint standardization; in 2009 the company bought 10 meters of clean paint room ; the surface treatment of cardan shaft is more standardized; paint fastness is more rugged; staff's working conditions improved; exhaust of harmless treatment;Third;Professional transport packagingThe packing of the export cardan shaft is all in the same way as the plywood wooden box; and then it is firmly secured with the iron sheet; so as to avoid the damage caused by the complicated situation in the long-distance transportation; Meet the standard requirements of plywood boxes into Europe and other countries; no matter where can successfully reach all the country's ports;The following table for SWC Medium-sized Universal Shaft Parameters;DesignsData and Sizes of SWC Series Universal Joint Couplings
