The new KISSsoft release 2023 comes with numerous novelties. Among others, Gear Mesh Frequencies (GMF) can now be calculated for cylindrical and bevel gears. GMF results are visualized in two different diagrams, i.e. GMF versus rotational frequency of the reference gear, and GMF versus amplitude.

The performance of an Electric Vehicle Power Unit is directly connected with critical tolerances. Tolerances drive opportunities for performance enhancement with cost reduction. The tests normally used to determine and validate tolerances are both expensive and time consuming with prototype parts. By replacing the initial tests with Digital Twin simulations, results can be obtained quickly, and at a much lower cost. This article discusses one of these tests and the results. 

GWJ Technology GmbH has extended the output option of tooth forms of involute gears. GWJ has extended the output of tooth forms in 2D DXF format in its calculation modules single cylindrical gears, cylindrical gear pairs, planetary gear trains, three- and four-gear train systems, gear racks and involute splines as part of the new versions of its calculation solutions eAssistant and TBK.

With the help of KISSsoft, the user can now estimate the influence of manufacturing deviation on the resulting transmission error and excitation force.

Dontyne Gears is looking forward to IMTS to promote the company’s range of gear design services developed during COVID restrictions. Dontyne Gears continues to work with companies to complete design projects including CAD models and drawings if required. They recently purchased an Okuma Genos 5-axis to add to the Osaka Siemitsu high accuracy gear inspection center already in house for prototyping. As well as cylindrical gears it is possible to produce straight, spiral, and hypoid bevels. The work is facilitated by using Gear Production Suite from Dontyne Systems to generate tool forms, G-code, and inspection protocols which can be used by the machines. 

A new version of the MESYS shaft and rolling bearing analysis software including new functionality is available. The bearing analysis software allows the calculation of the load distribution within the bearing and bearing life according to ISO/TS 16281 and it is integrated in a shaft system calculation with additional possibilities like modal analysis, strength calculation for shafts and interfaces to gear calculations. Currently the software is used by customers in 30 countries on four continents.

2022 marks the 20th Anniversary of SMT’s focus on providing the tools and knowledge to drive engineering innovation in gearbox system analysis. With this historic company anniversary, the company has announced the return of the North America User Forum.

Aircraft engines can be made more efficient by integrating planetary gears. In such an application, the planetary gears experience very high load cycles under fully reversed bending loads. Pulsator test rigs, which nowadays offer the possibility to perform UHCF investigations, can only be used for purely pulsating loading of gears. Therefore, for the investigation of the UHCF tooth root load carrying capacity under fully reversed bending load, a back-to-back test rig is required. Back-to-back test rigs usually have speeds of n = 3,000 rpm, which makes investigations in the UHCF range take a very long time. Therefore, a high-speed back-to-back test rig was developed.

The new KISSsoft Release 2022 provides numerous innovations - amongst others, in order to include the tooth fatigue limit in the verification, the information can be generated from time series.

SEGULA Technologies and British scale up Senseye, specialized in predictive maintenance based on artificial intelligence, have announced the signing of a partnership.
