青山傳動20年來以嚴謹的態度不斷改進上百道精密工序、五十道生產檢測環節，用工匠精神打造每一條萬向軸，旨在為客戶提供更好的產品和服務。

　　In the past 20 years, Qingshan Transmission has continuously improved hundreds of precision processes and 50 production inspection links with rigorous attitude, and built each universal joint shaft with the spirit of artisans, aiming to provide customers with better products and services.

加工

 

 

 

　　法蘭叉頭、焊接叉頭用數控車加工，保證定位止口公差在H7-H9之間，保證零部件同軸度在0.1mm以內，從而保證整軸可以平穩運行、不跳動。

　　The flange fork head and the welding fork head are processed by CNC machine to ensure the positioning tolerance between H7-H9 and ensure the coaxiality of the parts within 0.1mm, so that the whole shaft can run smoothly without jumping.

 

 

 

　　法蘭叉頭的法蘭平面上的螺栓孔與鍵槽的位置度關系非常關鍵，利用CNC加工中心加工的孔中心距、鍵槽精度高，而且對稱度、垂直度能達到小于0.02mm。

　　The positional relationship between the bolt holes on the flange plane of the flange fork and the keyway is very critical. The center distance and keyway of the hole processed by the CNC machining center are high, and the symmetry and verticality can reach less than 0.02 mm.

熱處理　　

 

 

 

　　我們的法蘭叉頭、焊接叉采用ZG35CrMo，為消除鑄造應力、提高材料機械性能，我們對所有法蘭叉頭、焊接叉進行調質處理，硬度達到238-268之間。

　　ZG35CrMo is used for our flange forks and welding forks. In order to eliminate the casting stress and improve the mechanical properties of the materials, we have tempered all flange heads and welding forks with a hardness of 238-268.

　　調質可以提高材料的強度、塑性和韌性從而減少萬向軸在使用中損壞的機率，延長萬向軸使用壽命。

　　Quenching and tempering can improve the strength, ductility and toughness of the material, thereby reducing the chance of damage to the cardan shaft during use and extending the service life of the cardan shaft.

產品檢測

 

 

 

　　我們定制的平衡儀能平衡長6米，直徑1米，重3噸的萬向軸，對轉速高于300轉/分的萬向軸，出廠前都進行動平衡檢測,動平衡精度G16。

　　Our custom balancer can balance the universal shaft with a length of 6 meters, a diameter of 1 meter and a weight of 3 tons. For the universal joint shaft with a speed higher than 300 rpm, the balance check is carried out before leaving the factory，Dynamic balance accuracy G16。
