Project Description
Worm gearboxes are characterized by their high transmission ratio in one stage, compact design, self-locking capability, and low-noise running characteristics. The load capacity of worm gearboxes is significantly influenced by the heat balance of the gearbox.
The methods B and C currently described in DIN 3996 for calculating the tooth bulk temperature in worm gears are not reliable, especially for small sizes, and limit the ability to calculate the load-carrying capacity of worm gears. Therefore, the goal of the research project is to develop a more reliable calculation method for the temperatures occurring in worm gearboxes during operation so that an accurate load-carrying capacity calculation is possible. Therefore, a calculation method for the temperature needs to be developed, and the power loss calculation needs to be extended to include all significant influences on the power loss. It is also necessary to investigate different gearbox sizes and oil fill levels and take them into account in the calculation method in order to be able to represent the range of industrial applications.
