Need for Offset Shaft Alignment

Cardan Shaft or Offset Shaft with u-joints or typically called as drive shaft is used to transfer power from a driver shaft to a piece of driven shaft. Offset shaft means the shafts of the driver and driven elements are not in line with each other. In the cardan shaft assembly there can be any number of u-joints. For example a single Cardan shaft means in a cardan shaft assembly there is a u-joint at each end of a shaft. If cardan shaft assembly contains double Cardan shaft then it means that three or more u-joints in a shaft are used. But the most encountered shaft in an industry is a single Cardan shaft.

There are two parts that must be understood, proper phasing and angularity of the input and output shafts.


1.      Phasing refers to the position of the yokes that are part of the shaft. The two ends, or yokes, must be positioned parallel, or in line with each other. Failure to do this will cause the driven machine to speed up and slow down twice for every revolution of the driver. This will cause runability problems, as well as high vibration issues.



2.      The angularity of the input (driver) and output (driven) shafts in relation to the main shaft element must be equal at each end of the shaft. Based on speed and load some guidelines are established cardan shaft manufacturers industry about maximum allowable angle between the shaft and the yokes. The best place to get the proper information is from the cardan shaft manufacturers.



Alignment part of the job

When the driven machine and the drive are aligned correctly, place the shaft ends in the correct position. Shafts when aligned correctly make the angle of the yokes on both shaft ends equal when the driven and driver are on parallel planes in the vertical and horizontal axes. When driver and driven machines are not aligned, it directly affects on the speed of the driven machine and it is fluctuated.  That means the worse the angular misalignment, the worse the speed fluctuation.

Cardan Shaft

A cardan shaft is used for power transmission of torque between specially offset driving and driven shafts for position changing during operation. No other machine other than cardan shaft is capable of performing this task that is cardan shaft parts are the must have part of any industry.
Cardan shaft allows torque transmission but in order to allow spatial angular motion and changes of axial length, advanced constructional elements are ensured.



In this way, cardan shaft is the indispensable transmission component in automotive engineering and industry.

Cardan shafts offer

  • Multi functional application
  • Excellent efficiency
  • High reliability
  • Low maintenance
  • Easy use
They are an integral part in almost all industries with mechanical drives.



Selection and use of cardan shaft

Cardan shaft parts are used for various applications and thus it is almost impossible for anyone to select their size and predict their lifetime with reliable accuracy with just one general rule. The familiar failure probabilities applied for roller bearings apply to cardan shafts as well.
First of all we must choose the size of the cardan shaft so that its maximum momentary torque rating is not lesser than the maximum torque to be transmitted in the application. There are some other parameters also that are needed to be considered like deflection angle, speed, length, operating conditions (kind of drive, temperature, dust etc.).


Therefore if you want comprehensive range of premium quality cardan shaft parts, then there must be reliability and quality from cardan shaft manufacturers. We introduce ourselves as Cardan Shaft manufacturers in India Company with a professional approach that is aimed at result orientation. With roots that go back to more than eight decades, we have etched a respectable place for ourselves in the international market by exporting quality products. Cardan shaft suppliers of Dullabh Commercials offer a comprehensive range of premium quality spare parts.

 Cardan shaft maintenance

It is necessary to grease the moving cardan shaft parts at certain intervals to remove used lubricant and foreign matter, if any, and replenishing the lubricant. Lubrication is required after cleaning with high pressure or a steam jet.
