ZARXE - calculates measurement from tooth thickness
Besides span measurement, dimension over balls/pins, and profile shift coefficient, you can now also enter tooth thickness sn.
ZARXE - Import Involute Splines from WN2, WN4, WN5
ZARXE calculates measurement dimensions and addendum modification coefficient not only for spur and helical gears, you can also use it for involute splines. ZARXE provides now an import function to get the dimensions of involute splines from WN2, WN4 and WN5 software.
ZARXE - New File Format ZXE
In earlier versions, ZARXE used the file format ZAR of ZAR1+. Now, a new file format ZXE was created to save program-specific dimensions and measurement data.
You can use the new "Import ZAR1" function for to open older files from ZARXE and for import of gear data from ZAR1+.
ZARXE - New Input Features
In a new input window you can select the known measurement or xe, and ZARXE calculates and displays online all other data.
ZARXE - New Price
The price for a standalone license of ZARXE is now 95 Euros.
WN2, WN4, WN5 - CAD Data for Profile Drawing
Generation of CAD files from involute splines has been made more convenient now. New menu items "Tooth shape shaft" and "Tooth shape hub" open a configuration window to set resolution, drawing mode and tolerance. After that, just select if you want to generate a DXF or IGES file.
ZAR1+ View Menu
Menu "View" was structured with submenus for a better overview about the available options.
At "View->Tables", charts with gear data, measurement data and tolerances have been added.
Production drawings and tables for gear 1 and gear 2 can now be displayed together on one screen.
ZAR5 - Menu Structure
Like in ZAR1+, the ZAR5 menu was newly structured by means of submenus.
New menu items are "View->Tooth" and "View->Gear Geometry" with drawings of tooth gap and gear wheel for sun, planet and ring gear.
FED10 - Asymmetrical Leaf Springs
Until now, only symmetrical leaf springs could be calculated with FED10. Input is easy for symmetrical leaf springs, sections are simply defined by width and length. New version 2.0 supports also asymmetrical leaf springs. Asymmetrical loads (that cause torsion) are not supported, all loads are centric. Input of asymmetrical geometry is not as easy, you must define internal and external coordinates of each section. For internal calculation, asymmetrical leaf spring is converted into a symmetrical leaf spring geometry of identical properties.
TR1 - Menu and Calculation Options
At Edit->Calculation, a new window was created to choose calculation options.
Diagram menu was structured with submenus for xy plane, xz plane, resulting vector, or all together.
TR1 - Buckling Safety for Fixed Clamping
TR1 calculates radial deflection by axial load for girders with fixed clamping or fix/loose bearing.
WL1+ Resonance Curve
Y coordinate of resonance curve is now Amplitude Az/(Fz/c) without dimensions.
SR1 - Database Menu and Temperature Window
New submenus for database menu ease the overview about available database files. A new window was created for temperature input.
SR1 - Thread Diameter dmin and thread strip safety
SR1 calculates bolt diameters d2 and d3 if you select a tolerance class. Or you can choose to enter it manually. For this case is d2min=d2max=d2 and d3min=d3max=d3 and d_max=d. The minimum thread diameter d_min is used for calculation of thread strip safety according to VDI 2230, so you also have to input d_min now. The calculation of thread strip safety according to VDI 2230 is based on Alexander formulas from 1977. But it seems that this formulas are not complete, valid only for the case that bolt material is better than nut material. For case of same material or nut material better, Alexander defines another calculation with factor C2. This one is not found in VDI 2230. Better use calculation of thread strip safety according to Dose.
