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.
