The web based eAssistant from GWJ Technology allows calculations for machine elements based on DIN/ISO standards. The following calculations are available:

  • Shaft calculation including strength according DIN 743
  • Cylindrical gears with strength calculation according to DIN 3990, ISO 6336 and AGMA 2101 with configurations gear pair and planetary gear stage
  • Bevel gears (straight, helical or spiral) with strength calculation according ISO 10300
  • Rolling bearing life according DIN ISO 281 including database of manufacturers SKF, NSK, SNR and KOYO
  • Interference fit according DIN 7190 including influence of temperature and centrifugal loads
  • Keyways according DIN 6892
  • Splines according DIN 5480 and strength according Niemann
  • Timing belts with an arbitrary number of pulleys and tensioners
  • Compression springs according DIN EN 13906-1
  • Tension springs according DIN EN 13906-2
  • Bolt calculation according VDI 2230

The calculation for helical gears can be called by MESYS Shaft Calculation. This allows the calculation of a shaft system coupled by gear pairs.

A description of calculation possibilities is available in the manual. You can register for a free test version with 5h time account.
