1 Changes from Release 03/2011 to 03/2012 Changes from Release 03/2011 to Release 03/2012 General Module General KISSedit Data Base Tool changes / enhancements Menu Project: drag and drop of files between several projects is possible. Menu extras: in configuration tool all user specific settings can be restored in one click. Online activation is improved. ISO 286 (tolerances as i.e. for diameters and bores) are extrapolated to higher values for "H", "h", "js", "JS" than the standard range provides. Progress indication with abort capabilities for time-consuming calculations. Enable/disable this feature from KISS.INI and from menu Extras/Settings/General. Input fields for filenames are suggesting a list of files to chose from, to make the selection faster. An "Undo" and "Redo" functionality is provided based working steps. Any changes of units for tables (such as Fine sizing, etc). will be restored after closing the window. Module calculation number is removed from the modules tree window. Some HTML Tags were not shown correctly, this is fixed now. KISSsoft file names don t allow comma anymore. Graphics: Export of graphics in DXF format allows the scaling of axis. the line thickness can be modified now. Comment field is placed directly below the graphic. Reports: comments from file properties are shown in the report header. Functionality for comparing reports with colorized markings for larger (green) or lower (yellow) values. Search functionality added, using the right mouse button. User can now select multiple entries to hide or reactivate the entries. Lubricants database: several oil data for Shell Oils are added.

Bearing database: cylindrical roller bearing (double row) from IBC are updated or corrected. 1 /

2 Base packages ZPK Scuffing calculation: the parameters spec. heat capacity and spec. heat conductivity are added in the database "material basic data". The parameter thermal contact factor is calculated acc to ISO/TR Micropitting calculation: the changes are adopted, that the profile modification can be defined as "none" or "optimal". Also different testing conditions (oil temperatures) for the load stage test (SKS) can be selected. Hardened layer: safety is calculated and listed in the main report (section 4c), if the hardening depth t550 is entered. The calculation is based on the DNV Wear factor according to Plewe extended to 2mym and added the unit to mm^2/n/10^9 Tolerance calculation according "Proposal DIN " is removed. For gears with undercut and tool with protuberance, the root form circle is calculated more precisely. New tabs "Load" and "Coefficients" added in order to provide faster access to the data, as i.e. KHbeta, etc. Material data: properties for POM (VDI2545) are changed so that the max temperature is 100, since the material is not anymore stabil in shape using higher temperatures. Material data for 2 sintered material "DISTALOY AE" (Fa. Höganäs) implemented. Tab Basic Data: inner diameter can be entered with wall thickness factor now. Thickness of cross-piece can be entered also as absolute value or as a factor. Tab Load: load spectra definition enhanced with input of individual values for the coefficients KHB, YM and Kgam (per flank) for left and right flank. Also with own input, the input types "load " or "torque" are available. The data can be entered as factors or as absolute values. Prestress according to Alstom can be considered in "strength" "Details". Tab Coefficient: KHB calculation is moved from tab "Contact analysis" to tab "coefficient". The calculation acc. to ISO 6336 Annex E. A choice is added (under settings) if as tooth stiffness c (as defined in ISO6336) or cm=11 N/mm/ (as in AGMA927-A01) should be used. Tab Reference profile: input of length alternatively to factors possible, tip alteration is moved from "Basic data" to "Reference profile", while changing from "reference profile" to "Constructed involute" the values are automatically transferred, layout of tab slightly rearranged. Tab Modification: the column "information" is added where the information of KISSsoft are shown. The modification "Twist" is added for 3D STEP model (so far, it was implemented for Contact analysis calculation) Tab Tooth Form: Any intermediate steps of "automatic" are now listed and can be selected as a result, which will be applied then in the 3D model. Graphics: specific sliding shows also the results for "without backlash". Hardness depth acc. to DNV41.2 is added, also the safety value. in Graphics "2D Geometry" new graphics are available for "Flank curvature radii" and "Angle of flank normal". The export of half tooth (mirrored) is now available too. In Graphics "3D Geometry" the deviation of axis can be defined now and the contact lines can be checked easily (with skin model). This is available for cylindrical gears, planetary gears, worm gears, crossed helical gears and face gears (for bevel gears this was already provided in the previous release). Parasolid: settings are moved from "Graphics" or KISS.ini to "Module specific settings". Herewith the settings are saved in the individual KISSsoft calculation, and only the relevant model types are shown for each gear type. 2 / 6

3 WPK MPK SPK FPK APK Export: the bearing (roller bearing or hydrodynamic bearing) can be saved in a separate KISSsoft file and opened in the respective bearing calculation. Shaft editor: with right mouse click on the roller bearing, the option is added to position the bearing to left or right shoulder. A shortcut for coupling is added in the tool bar (right hand side). Size of symbols for general bearings and loads can be adjusted with a slider. The option can be activated to move bearings and loads. This is provided to avoid unintended moving of elements. Elements-tree: copy & paste of bearings for "connecting elements" is now possible. Free cross section with type "shoulder with interference fit" added. Element editor: the input of own load spectra directly in the element editor is available now. Element editor "bevel gear": input of length of load application is changed to input of face width. Element editor "Shaft": New option Pre-turned to actual diameter (shoulder: K1 from d) in the list State during heat treatment available. This uses the smaller diameter d to define the geometric size coefficient K1. In all other cases (cross sections) will be used the bigger diameter DA to calculate K1. Also a new option is given to disable the report of the shaft in the main report. Herewith, using coaxial shafts, unwanted reporting can be avoided. Module specific settings: definition of oil level changed from bearing out diameter depending value (see "H") to shaft center line (see "h"). Report: center of mass calculation added for every shaft, shown in the shaft main report Tab basic data: The force element "gear" can be considered now with the mounting condition "Interference fit". Tab Strength: sizing of required service life is available (optionally also considering load spectras). The options "Miner original acc. to Haibach" and "Miner enhanced acc. to Haibach" are now available when working with load spectra. Also the possibility to skip the shaft strength calculation completely is available now. Bearing calculation (classical method): friction calculation acc. to SKF 1994 or SKF 2004 selectable. In case of undefined coefficients these values are approximated by KISSsoft. Newer standards are implemented: Calculation of the thermal speed rating according DIN ISO (old: E DIN (Draft)) and the thermally safe operating speed according DIN 732 (old: E DIN (Draft)). In case the coefficients are not known in the standard, they are approximated by KISSsoft. A new calculation for snap ring (Seegerring) is added, where results as axial permissible force etc are calculated. Splines according ISO4156 are updated to edition For cylindrical Interference fit, the external pressure on hub is possible. A conversion for multiple interference fit is added. For conical interference fit the calculation method E DIN is added, as well as the input for bores for the calculation procedure acc. to Kollmann. The key calculation has the additional input of maximum backwards torque, which is used for the calculation of load direction changing coefficient fw. Tab Basic data: For the calculation of the tightening factor A, the input is provided for minimum, mean or maximum value, as given in VDI2230, table A8. Result window shows now the safety factors for maximum attained pretension force, instead of the maximum required pretension force. Herewith different values are shown than before. There is now a warning appearing if the loose Torque [ML] is negative, since the bolt connection could be released automatically in that case. Tab Results from FEM calculation: after selecting the configuration "Proof for bolts with FEM results" the new tab is activated, which allows the calculation using the ductilities from FE results, acc. to VDI (Gründruck edition). The model classes II and III are available. Stripping strength: the input for "minimal external diameter bolt" and "maximal flank diameter inner thread" are provided, in order to calculate the minimum reach of screw acc. to VDI 2230, Eq. 5.5/49. Graphics: the segment of annulus are now presented with the center line and complete outer diameter. Separate drawing data reports for springs are available now. Disk springs standards DIN 2092 and DIN 2093 are updated. Clutch calculation added acc. to VDI Graphic are available and several friction coefficients are provided as user input. 3 / 6

For chain drives, the minimum tensile strength Fu is added in the database and the report (value from ISO 606). System Module KISSsys SYS Tables: new layout with many improvements: the cells can be formatted individually with font size, text and background colours. Also the columns width can be arranged individually. Model setup: new assistant available to build complete KISSsys models by clicking the elements, constraints and calculations. This is a much more comfortable handling. An automatically naming of the elements is available too, which allows own definitions. Table setup: the variables for text (headers, titles,..), expressions (calculation input fields) and references (calculation result fields) can be pasted by drag and drop. Also assistants with right / left mouse buttons are provided, as well as in the toolbar. Programming: An additional tool (based on Eclipse) is available, which provides an programming environment to create and support own codes in KISSsys more License tool: the KISSsoft license file can be selected or changed now in KISSsys too ("Extras" "License tool") Configuration tool: The user can reset different settings, same handling as in KISSsoft now. Program settings: The user can define now own settings for KISSsys tables, messages, etc. Load spectra: the load spectra is now provided as selection from KISSsoft database too. Parameters: many more parameters for the sizing of gears are now available, such as profile shift, tip thicknes limit, etc. Classes: New classes for "four gear" calculation and "snap ring" calculation (only without system) added. Expert Modules Gears Cylindrical gears Configuration / Dimensioning ZA1 The dynamic factor KV can be entered manually. ZA3 ZA4 The overlap ratio can be defined, alternatively to the helix angle. The calculation procedure is redefined, much more solutions are provided now. Fine sizing functionality with load spectra possible. The maximum profile shift can be determined now acc. to minimum topland instead of balanced specific sliding. The face width can be changed (one value only, no range). The original design can be shown in the graphic as "Nr. 0" for comparison reason. Methods for strength calculation ZA10 The meshing stiffness cy for line load w<25n/mm is set to 25N/mm ZA12 ZA17 ZA19 Young's Modulus is set to 30'000'000 lbf/in^2 in order to avoid different results for AGMA2101 (metric) and AGMA2001 (imperial). Material database: new plastic material data from SABIC RCL-4036 (PA66, Glas fiber) and replacement of WLF-4036 with WFL-4036 FR. The calculation method DNV 41.2 (Det Norske Veritas, Edition may 2003) is added. 4 / 6

5 Contact analysis ZA30 Axis inclination and deviation error can now be scaled with the partial load factor wt. Total power loss over one pitch is calculated. Planetary system: the interaction between meshing stiffness of sun gear - planet - inner gear is now considered as a system. Also the individual pitch error and centre distance errors per planet can be considered and Kgam is calculated. Graphics / Evaluations: method for extrapolation of data can be defined by the user now. The legend for 3D graphs is improved. For many 2D graphics the selection of displaying the results of a required disk or the required planet is now possible. A new graphic "single tooth stiffness" is implemented. ZA34 KH beta calculation added acc. to ISO Annex E. Bevel gears ZC1 ZC2 ZC9 ZC11 ZC12 Material data for bevel gears acc. to AGMA 2003 added In the report, the mass calculation is added. Tab Basic data: Input for pitch apex to inner blank and outer blank introduced. The default values are to have the distance from the tip to the blank are three times of the normal module in the middle. The values are considered in the 3D models. Tab Reference profile: Preliminary treatment is added. This allows to create 3D models for precutting process, together with the selection in module specific settings Tab Modification: Tip relief value is now related to the modifications, so the same handling as with cylindrical gears is now given. For existing calculations with tip relief values a profile crowning with the same value will be added automatically. Tip alteration can be entered, for toe and heel side, with conversion functionalities. Twist modification is available too. Both are applied to 3D models. Module specific settings: settings for Parasolid are moved from "Graphics" or KISS.ini to "Module specific settings". Herewith the settings are saved in the individual KISSsoft calculation. The option is given to apply "constant root rounding radius" and constant protuberance" along the face width. New calculation method ISO/CD10300:2011 (Committee Draft) for bevel gears added. New calculation method ISO/CD10300:2011 (Committee Draft) for hypoid gears added. Calculation method for bevel gears DNV 41.2 (Det Norske Veritas, Edition may 2003) is available.

New bearing types for calculation with inner geometry added: double row cylindrical roller bearing and axial deep groove ball bearing. The graphic for Hertzian pressure along the profile is added. The load distribution of gear can be calculated iteratively. Alternately the load is updated according to the load distribution, a calculation is again performed. This leads to different results than without iteration. The iteration can be activated in module specific settings. Sizing is added, to get a proposition for modification. together with the iteration, several steps may be necessary.
