Mechanical engineering cardan shaft

Mechanical engineering cardan shaft



A shaft with a universal joint at its end to accommodate a varying shaft angle.
Inmotor vehicles, a Cardan shaft is used to connect the motor and transmission(at an angle of up to 5°), the transmission and transfer case (at an angle ofup to 5°), and the transmission or transfer case and the rear-axle drive (at anangle of up to 15°), as well as in steering gear or winch drive.
ACardan shaft consists of a propeller shaft with two (less frequently one)Cardans. If the propeller shaft is connecting mechanisms between which theangle and distance vary (for example, the transmission and rear-axle drive of amotor vehicle), overhang balance is provided in the form of a slip splinedjoint, which makes possible a change in the length of the shaft within setlimits. Depending on the angle between the propeller shafts in a Cardan shaft,rigid or flexible semi-Cardan joints, full Cardans of unequal angular velocity,or Cardans of equal angular velocity may be used. Full Cardans, which have twojaws, needle bearings, a spider, mounts for the spider journals, and atightening mechanism, are the most commonly used type. The efficiency of asingle Cardan is 0.985–0.99.

Correct selection,installing and carefull maintenance are the important conditions to make the coupling use normally,so please pay attention to following points:
1.Correct selection is important for excellent performance of universal joint shaft / cardan shaft .
2.Must specify this gerneral drawing number when ordering the same parts.
3.Class 10.9 bolt is coated with anaerobic adhesive to prevent looseness.
4.In order to use it easily,we recommend cooperation f8 for outshot of flange and cooreration H8 or keyway of end surface key.Keep flange surface clean when  installing and check the connecting bolts regularly ,and tighten them with a stipultated pre-tightening force. When putting spline shaft into spline tube,the central lines of bearing holes on both ends should be the same plane to guarantee the shaft work synchronously.
5.Our products have been injected grease already after production.Please lubricate it in one or two months after installation and use.
6.Pay attentation on preventing water,dust and other corrosive substances.Please don't knock the device with hammer or it will reduce the service life of the product.
7.If there is abnormal sound or move us and down,please examine it in time by professional .
