AB  - During the last few decades, the requirements for modern machine elements in terms of size
reduction, increasing the energy efficiency, and a higher load capacity of standard and non-standard
gears have been very prevalent issues. Within these demands, the main goals are the optimization
of the gears’ tooth profiles, as well as the investigation of new tooth profile designs. The presented
design idea is based on the optimal solutions inspired by nature. Special attention is paid to the new
design of the tooth root zones of spur gears in order to decrease the stress concentration values and
increase the tooth root fatigue resistance. The finite element method is used for stress and strain
state calculations, and the particular gear pair is modeled and optimized for these purposes. For
tooth root strength analysis, the estimations are based on the theory of critical distances and the
stress gradients obtained through finite element analysis. The obtained stress gradients have shown
important improvements in the stress distribution in the transition zone optimized by biomimetics.
An analysis of the material variation influence is also performed. Based on the investigations of a
particular gear pair, a significant stress reduction of about 7% for steel gears and about 10.3% for cast iron gears is obtained for tooth roots optimized by bio-inspired design.

AB  - The basic definitions and a history of the development of biomimetics as a discipline that
considers nature-inspired design are presented in this paper. The discussion and the results of the
application of principles of nature-inspired design in machine elements design are given. The fact
that transition zones that Nature chose and designed on trees in many cases survived for more
than a hundred years, resisting on the various and variable external loads and other external
conditions, is considered. Presented case study used the nature-inspired transition shapes in the
research of innovative design and geometric optimization of transition zones of high-loaded
shafts. The comparative Finite Element Analysis is performed for a particular transition zone with
traditional engineering design, as well as with nature-inspired design. The conclusions about the
increase of load capacity that is obtained with innovative biomimetics design are discussed.
