GWJ Technology Upgrades eAssistant Software
January 28, 2015
GWJ Technology GmbH, headquartered in Braunschweig, Germany, has upgraded its web-based calculation software eAssistant with three new modules for the calculation of rack/pinion gear pairs as well as single external and internal cylindrical gears.
In addition to various calculation modules for many different machine elements (e.g., shafts, rolling bearings, shaft-hub connections, bolts, cylindrical gears, planetary gear trains, bevel gears), GWJ has released three new modules. Two modules can be used for the determination of single cylindrical gears. One module allows to calculate single external cylindrical gears, the other supports the calculation of single internal gears. Both modules enable eAssistant users to determine the gear geometry, test dimensions and allowances including the accurate gear tooth form.
The third new module makes it easier than ever to calculate rack/pinion gear pairs. Spur and helical gears are possible to calculate. Profile shift on the pinion will be taken into consideration. The number of teeth or the length of the gear can be specified for the gear rack. The user can decide between rectangular or round gear racks. In addition to geometry, allowances and gear tooth form, the load capacity according to DIN 3990 and ISO 6336 Method B can be easily calculated. Herewith the safeties for fatigue or limited life strength and static strength can be determined. The calculation of surface durability (pitting), tooth bending strength and scuffing according the flash and integral temperature method is carried out.
