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.
