FED10 - Leaf Springs
FED10 Software for calculation of leaf springs is available now, price is 500 USD.
ZAR5 - Roller bearing calculation for planet gears
Roller bearings for the planet gear wheel can be selected from database, ZAR5 calculates geometry and life expectation. Databases with groove ball bearings, self-align.ball bearings, needle bushes and bearings, cyl., taper, self-align. and skew-angle roller bearings of LG1 and WL1+ are delivered now with ZAR5, too.
ZAR5 - Sectional Drawing
A sectional drawing of the planetary gearing can be exported to CAD as DXF- or IGES file.
ZAR5 - Quick-View
Gear data and results are listed in four tables
ZAR5 - Addendum Modification and Center Distance
New options for input of center distance and addendum modification coefficients: By option "a const", center distance is fixed, input of xS, xP, or xH changes the two other coefficients. If not "a const", center distance and one addendum modification coefficient are changed.
ZAR5 - Table Drawing
A table drawing with draft of the planetary gearing and essential values and results can be printed or exported to CAD.
FED1+, FED5, FED6 - Setting Length=Block length
For "Ls=Lc", block length is used for setting length. Else setting length is an input value.
FED4 - Spring Rate and Spring Energy of Disk Springs
New diagrams show spring rate and spring work as function of spring travel. Because characteristic line of disk springs is degressive, spring rate decreases and even may become negative.
FED9 - kb coefficient
Stress adaption factor kb is calculated from Ri/t for dynamic applications, if both spring ends are fixed and not bended.
ZAR1+ Tolerance Analysis for Center Distance
If you want to analyse how center distance deviations influence gear data, this cannot be done by variations of the center distance, because addendum modification coefficients are adapted to the new center distance then. But you can adapt upper and lower tooth-thickness deviation. Nominal addendum modification coefficients may change, but generated addendum modification coefficients must remain unchanged. Generated addendum modification coefficents are calculated to this formula:
xe = x + Asn / (2 * tan(alpha) * mn)
Reversed we can calculate the required tooth-thickness deviation Asn with:
Asn = (xe - x) * 2 *mn * tan(alpha)
The new option "Analyse Asn=f(a)" recalculates x1 and x2, Asne/Asni 1,2 so that generated addendum modification coefficients and tooth shapes of gear1 and gear 2 remain unchanged, after you changed center distance. Result is tooth clearance or meshing surface.

Append-Button for Databases
Click "Append" button to add a new record to be filled with data of the current row. This option is useful when adding new records with similar data, so that only the different fields have to be modified.
SR1+ Tolerance for Tightening Torque
Tightening torque with tolerance is displayed at input window. Changes of tightening coefficient alphaA will change upper and lower value of tightening torque. alphaA considers deviation of both, friction and tightening torque. First enter upper and lower friction coefficients, before tightening torque tolerance can be calculated.
Compare variation by means of Excel
If you want to compare some variants of a calculation, export the printout after every calculation to a new Excel worksheet (at OLE->Excel->Printout). Then copy the column with the values into one worksheet. Now you can make Excel calculate difference values and specific factors, or draw diagrams.
Modification Index 1,2,3 or a,b,c
At "File->Settings->Graphics" you can configure if modification index at production drawings should be 1,2,3.. or a,b,c..
Floating licences for Software Packages and Bundles
The integrated licence manager controls for every program separately, how many programs run at the same time. For example, if you purchased a 1-user floating licence of the HEXAGON Mechanical Engineering Package, 28 users could work theoretically at the same time with HEXAGON software, if everyone uses another program.
Other software companies have other practices: if one runs one module, all the other modules of the packages are blocked for other users.
