Computer Resources is the creator and publisher of Machine Train Calculator, Gear Box Calculator and Bearing Frequency Calculator. These are Windows based computer programs designed to calculate vibration frequencies with the click of a button.

If you are involved in the maintenance field and use vibration analysis to monitor machine condition, then these programs are for you.
Machine Train Calculator

Calculating machine train frequencies by hand is a very tedious, time consuming, and error prone task. Machine Train Calculator can help to simplify this job by using the computer for what it does best, calculating and searching data, and then using you for what you do best, the actual analysis.

The bearing database contains over 21,000 bearings.

Common Frequencies Calculated

  • Bearing frequencies (BPFI, BPFO, BSF, and FTF)
  • Gear mesh frequencies
  • Chain tooth frequencies
  • Belt and chain speed frequencies
  • Fan blade and pump impeller frequencies

Machine Train Calculator approaches the task of calculating vibration frequencies on a modular basis. This saves a great deal of time when building machines in the database and also avoids redundancy of data. A list of the modules as well as an explanation and a screen shoot from the program is shown in the link below.

Gear Box Calculator

Calculating gear box frequencies by hand is a very tedious, time consuming, and error prone task. Gear Box Calculator can help to simplify this job by using the computer for what it does best, calculating and searching data, and then using you for what you do best, the actual analysis.

The bearing database contains over 21,000 bearings.

Common Frequencies Calculated

  • Bearing frequencies (BPFI, BPFO, BSF, and FTF)
  • Gear mesh frequencies
  • Hunting tooth frequencies

The Gear Box Calculator allows you to build a database of gear boxes and then calculate gear box frequencies based on that data. A Gear Box Wizard is built into the program to make the building of gear boxes easier.A list of the modules as well as an explanation and a screen shoot from the program is shown in the link below.

Bearing Frequency Calculator

For those who don't need all the bells and whistles of Machine Train Calculator or Gear Box Calculator and who simply want to calculate bearing frequencies, this program may be just what you need.

If you are used to performing this task by hand, you can appreciate that this is a very tedious, time consuming, and error prone task. Bearing Frequency Calculator can help to simplify this job by using the computer for what it does best, calculating and searching data, and then using you for what you do best, the actual analysis.

Common Frequencies Calculated

  • BPFI (Ball Pass Frequency Inner Race)
  • BPFO (Ball Pass Frequency Outer Race)
  • BSF (Ball Spin Frequency)
  • FTF (Fundamental Train Frequency)

10 harmonics are also calculated for all the frequencies mentioned above.

The bearing database contains over 21,000 bearings. You can add as many more as you like.

Bearing Frequency Calculator is composed of two modules. These are the Bearing Data module and the Bearing Calculator module.A list of the modules as well as an explanation and a screen shoot from the program is shown in the link below.
