At first sight the appearance of 5-axis milling for bevel gears opens new possibilities in flank form
design. Since in comparison to existing machining methods applying cutter heads no kinematic
restrictions exist for 5-axis milling technology, any flank form can be machined.
Nevertheless the basic requirements for bevel gears did not change. Specifications and functional
requirements like load carrying capacity and running behavior are still increasing demands for design
and manufacturing. This paper describes the demands for gear design and gives an overview about
different design principles in the context of the surrounding periphery of the gear set.
In the design process of transmissions, one major criterion is the
resulting noise emission of the powertrain due to gear excitation.
Within the past years, much investigation has shown that the
noise emission can be attributed to quasi-static transmission error.
Therefore, the transmission error can be used for a tooth contact
analysis in the design process, as well as a characteristic value for
quality assurance by experimental inspections.
