Cardan Shaft? Spacer Shaft? What Kind Is It?
Recently, I provided training for a location that had vertical mounted electric motors driving pumps that were one or more floors below them. In this case, these pumps were driven with Cardan Shafts, however they did not have the typical 5-to-15-degree angles (between the motor & pump shafts and the drive shaft) recommended for lubrication…Read More
Understanding Spacer Shaft Alignment
The majority of precision shaft alignments are relatively close coupled where there are only a couple of inches between the shaft ends of the driver and driven elements. Close coupled alignment quality is traditionally displayed as angle (driver to driven) and offset (at the center of the coupling). The question is what do you do…Read More
Spacer Shafts, Jack Shafts, Line Shafts, and Spool-pieces
In shaft alignment, the terms Spacer Shaft, Jack Shaft, and Spool-piece are often interchanged. They refer to a shaft which connects the driving machine to the driven machine. While the name is not so important, the type of configuration must be known, because the method of alignment can be different depending upon the type. They…Read More
