Face Gears
SP 4 - Calculation error in the face gear for shaft angle not equal to 90 degrees
Some of the geometries such as the height of the gear body and the assembly distance were wrong for the face gear with the shaft angle not equal to 90 degrees.
SP 4 - Measurement grid of face gear fixed
The measurement grid of a face gear with a shaft angle not equal to 90 degrees and with an axial offset was wrongly disabled since the release 2021 SP3. Now it's enabled again.
Shafts
SP 4 - Forced response graphic could not be exported as curve
Fix in the export of Forced Response graphics as curves.
Bearings
SP 4 - Bearing rating life in revolutions in the special report for classic bearing calculation
Rating life in revolutions (L10 and Lnm) in the special report for classic bearing calculation were always calculated by considering nominal bearing speed. This resulted in wrong results when considering load spectrum with different rotating speeds.
SP 4 - DIN 31652 with ring nut didn't use the half width to define the lubricant flow rate Q1
For the calculation according DIN 31652 for with ring nut arrangement uses the half width to define the lubricant flow rate Q1. Until now, the whole width was used.

SP 4 - Roller length in case of proprietary rolling bearing internal geometry data
In case of using proprietary rolling bearing internal geometry data, the roller length and the positions of roller sections are no longer shown in the rolling bearing reports and in the graphics. Instead, only the numbers of rolling element sections are shown.

KISSsoft will now show custom bearings (manufacturer=OTHER) and RKB bearings in bearing selection drop-downs by default also for calculation files made with KISSsoft releases prior to 2022. In case of existing older calculation files until now these two manufacturers had to be explicitly turned on in module specific settings.

When calculating Campbell diagram or Forced response with more than 1 shaft the calculation didn't consider correct shaft speeds of non-reference shafts if own shaft speed was set for these shafts.

KISSsoftis a modular calculation program for the design, optimization and verification of machine elements according to international standards. The individually customized software packages for a wide variety of applications guarantee tailor made solutions and the integration to all common CAD software complete the product.
TheKISSsoft release 2022provides numerous innovations - amongst others, in order to include the tooth fatigue limit in the verification, the information can be generated from time series. The determination of load spectra from time series (torque-speed-time) is now an independent module ("Load spectra"), which can be used to calculate load spectra for gears and for shafts/bearings. In addition to detailed reports, many graphics are now available for displaying the results. Positive and negative torques result in alternating load in the tooth root. The Rainflow method is used to de-termine the number of cycles with a shift from high to low torque. Based on this, the alternating bending factor YM, according to ISO 6336-3 (extended), is determined additionally for the load spectrum in the gear calculation of each element.
