TechBlog #22 | More flexibility in gearbox design: Load collectives in the FVA-Workbench
Conventional gearbox designs based on nominal power and speeds often fall short of meeting the requirements of modern applications, such as resource efficiency, high power density, efficiency, and longevity. The FVA-Workbench has previously allowed for the consideration of load collectives in the form of "scaled load collectives," incorporating scaling factors for speed and torque in power flow. The latest version of the FVA-Workbench has now introduced the feature of "flexible load collectives," expanding the software's capabilities. This feature enables the creation of arbitrary combinations of loads and engaged gears with their respective time allocations using an intuitive editor.

The goal of increasing the power density of a gear unit demands that extraneous material reserves can be detected and reduced to the necessary level. In this context, it is important to know the influences acting on the gear unit and the resulting loads. Precise knowledge of the longitudinal load distribution in the gear meshes during operation, and specification of suitable microgeometries for its optimization, play a decisive role.
