Why is a driveshaft better than direct drive

How to increase flexibility in industrial drives by using a driveshaft?

The Problem:

We often come across industrial applications that are using a solid / rigid shaft between the power source and utility like the diagram below. This type of setup often has the following issues:

  • Both the power unit and utility shafts must be running perfectly inline which usually requires laser equipment to achieve. Without these shafts being inline, there is a huge amount of stress put on the shafts, bearings and seals which can result in premature wear or even failure.
  • When servicing the power unit of utility, the units will need to be re-aligned using specialty equipment again otherwise you run the risk of putting stress on the shafts, bearings and seals which can result in premature wear or even failure.
  • Any base flex will put the units out of line, even if this is minimal it can have an impact on the wear of shafts, bearings and seals.
  • Any vibration in each unit is amplified through the shafts to the other unit which can result in noisy operation and premature wear of the driveline.

The Solution:

To fix these issues the team at Beattys design and manufacture a universal joint driveshaft with a sliding spline to go between the power source and utility. As most applications are different we design and manufacture every driveshaft specifically to your needs. Putting in a driveshaft will bring your system the following benefits:

  • Removes the need to laser align the power source and utility shafts for vibration-free operation. This also applies for when servicing either the power unit or utility, there is no need to laser align the shafts again.
  • Easy access to both the power source and utility through the simple removal of the driveshaft also allowing for the power source to be left in place while servicing the utility.
  • All torque loading / shock loading is absorbed through the driveshaft rather than the input / output shafts. This helps prevent any premature wear of the running gear, bearings and seals.
  • The driveshaft will absorb any base flex rather than putting immense stress on the power unit and utilities input / output shafts.
  • Power unit and utility can be fixed on rubber mounts to absorb vibrations from general machine operation without the need to worry about alignment issues and premature wear of running gear, bearings and seals.
  • The power unit and utility can be mounted at different heights as long as the input / output shafts are running parallel. In some cases, this can save a lot of space or achieve much easier servicing access.
