▪ Using 2D FEM, you can calculate the tooth
root stresses for cylindrical gears (with straight
or helical teeth)
▪ This is of special interest for the rating of
grinding notches in the tooth root
Gears
Tooth root stresses by FE
Reseller Meeting 20174
▪ Either by selecting the
stiffness files directly
▪ Or by adding them to the
respective shaft calculation
▪ Supported stiffness matrix:
Code Aster, Ansys, Abaqus,
Altair OptiStruct
▪ Supported by pair, 3-gear-
chain, 4-gear-chain and
planet calculation
Gears
Gear body deformation
Can be considered by contact analysis (Cylindrical and Planet) and face load factor calculation.

Gears
Functionality
▪ Adding new plastic materials to the KS database
▪ Automatic generation of the corresponding DAT files
If fatigue data from gear testing is available
▪ Calculation of permissible tooth root/flank stresses
▪ Statistical evaluation of cycles to failure
2 calculation cases possible
▪ Identical test gears for all tests (testing on the test bench)
▪ Different test gears used (Z12, Z14, Z15, Z16) – mainly testing in
actual applications
Possible to calculate wear factors and heat transfer coeffcients acc. to
the VDI 2736

Gears
The results from test rig are used in KISSsoft to generate the
material data file
Results from gear tests

▪ You can check whether a required tip relief
can be generated with an available grinding
worm / dressing wheel.
▪ For this check, the system lists all available
grinding worms / dressing wheels from a
user-defined file.
▪ It then displays the grinding worms / dressing
wheels that are suitable in a table and shows
the manufactured tip relief for the current
gear.

▪ Shaft sizing
▪ equivalent stress
▪ outer contour (length/diameter)
▪ Bearing lifetime
▪ catalogue method
▪ collision detection
Shafts
Rough sizing (single shafts)
Reseller Meeting 20179
Shafts
Examples of rough sizing (single shafts)
Reseller Meeting 201710
Shafts
Load spectra with temperature
▪ Thermal expansion of shafts (affects reaction forces)
▪ Operating clearance of bearings (inner geometry) bending line ...
Reseller Meeting 201711
Shafts
Forced vibration
▪ The vibration of the shaft is calculated on the basis of the unbalance response
▪ The eccentric mass is defined as an additional mass
▪ The amplitudes etc. are evaluated at documentation points which can be positioned at any point on
the shaft.
Reseller Meeting 201712
▪ You can use variation calculation to
optimize the internal geometry of
bearings.
▪ The variants are displayed in a list, or
graphically
Rolling bearings
Fine sizing of inner geometry
Reseller Meeting 201713
▪ Elastic deformation of inner and outer ring
due to external loads
▪ typical application planet bearings
▪ arbitrary boundary conditions possible
(point/line load, elastic/fixed support)
Rolling bearings
Elastic deformation of inner / outer ring
Reseller Meeting 201714
▪ At a given axial position of a connecting
element, both shafts should have had some
geometry definition. However, this was not
realistic for thrust connections, and is
changed now.
▪ In addition, thrust needle cage bearings are
now available with inner geometry.

Oil data in the database
▪ New data for oils and greases added from Interflon
▪ Oil data from Klüber updated
Bearing data in the database actualized from:
▪ SKF
▪ Schaeffler (INA, FAG)
▪ TIMKEN
▪ KOYO
New bearing types in the database from different manufacturer:
▪ TIMKEN: deep groove ball bearings (single row), thrust sperical roller bearings
▪ SKF: hybrid deep groove ball bearings, hybrid cylindrical roller bearings (one row)
▪ INA: Axial angular contact ball bearings
Database
Reseller Meeting 201716
▪ Negative speed (counterclockwise) is
possible to input (only important for the
stiffness calculation – position of the reacting
force on the shaft)
▪ New calculation method DIN 31652:2017 for
radial journal bearings:
▪ for low speed bearings (So > 1)
▪ for bearings with circumferential angle
180°or 360° shells
▪ with formulas, that we don’t have to
read the values from a diagram or
iterate from a table.
▪ possible relations B/d from 0.001 to 5

Journal bearings
Reseller Meeting 201717
▪ Strength calculation according AGMA 6123:
▪ Additional calculation to the release 2016:
- influence of the misalignment and crowning
- calculation to check the ring bursting
▪ update to AGMA 6123-C16:
▪ main change is that the allowable torque rating Ta is calculated with the surface
hardness, in the old standard was this value calculated with the core hardness.

▪ Additional parameters in the graphic ‘Clamping’ and additional information in the graphic
‘Pretension’ if you input both tightening torque.

Formulas for the diameter Dd and Dh (with working mandrel or working bush)
Formulas for the angle and ’ changed (additional rotation angle)
Compression / Tension / Leg springs
▪ Some wire diameter tolerances added/ updated:
▪ Diameter tolerances according DIN EN 10218:2012 T1-T5
and DIN EN 10270-3 T12-T15 added

Shaft calculation
▪ FKM-guideline chapter 5.5 is integrated. In the strength calculation according FKM you have for
surface treated components only a global surface treatment factor. According the chapter 5.5 you
have an more detailed method to give an estimation for fatigue limit for surface treated components.
In this method you look about 2 Points:
▪ point on the surface RS
▪ point in the interior of the component at
the transitation between the surface
layer and the core.
For both points are the local elastic stresses to determine
(calculate the local stresses according FKM). With the input
of the surface hardness and the hardness depth or the tensile
strength (the hardness can be convert with this value).The utilization
at this 2 points should be smaller than 1, the bigger one is the
result of this theory.
