KISSsoft - Gear Design Software

KISSsoft® performs strength calculations quickly and accurately, and provides detailed documentation, including safety factors and service life values. KISSsoft is completed by interfaces to all standard CAD programs and links to FE calculations.


KISSsys - Transmission Design and Simulation

KISSsys enables users to model complete gear units and drive trains. KISSsys brings together kinematic analysis, 3D graphics, and user-defined tables and dialogs, allowing users to perform system level evaluations in one run while considering the interdependent effects of every single component of the gearbox. System reliability, load spectrum calculation, efficiency and thermal balance evaluation, modal analysis are now available, and more.


About KISSsoft

KISSsoft AG develops design software for engineers and designers in a wide variety of fields: whether they manufacture cable car systems, gears for construction equipment, Formula 1 race car transmissions or the tiny gears used in Mars rovers. When used in keeping with valid standards (DIN, ISO, AGMA), KISSsoft serves as a quick, high-quality tool for sizing transmission elements, reviewing calculations, determining component strength, and documenting safety factors and service life values.

Seamless Connectivity to GEMS Engineering and Manufacturing System

KISSsys and GEMS® are linked by a direct interface to exchange gear tooth and system design data. After the design of transmissions with KISSsys, bevel and hypoid gears are calculated and manufactured with GEMS. While designs are simulated more accurately than ever, they can also  be optimized in a closed loop system.

KISSsoft for Plastic Gears

An expandable database with polymer data is available in KISSsoft, as well as the calculation of the operating backlash, taking into account the influence of manufacturing and mounting tolerances as well as temperature and swelling. Injection molding forms are determined by compensation of the shrinkage and spark gap.
