Speed reducers incorporating cycloidal technology as their primary reduction mechanism have always been
active topics of research given their unique trochoidal tooth profile. A cycloidal reducer is recognized for its
strength and mainly studied for rotational performance improvement. Nowadays, this study can be performed
by digital prototyping, which has become a valuable tool for simulating exact scenarios without experimenting
on actual model.
This paper discusses the stress distribution, modeled in a dynamic simulation environment, on the rotating
parts of Cycloidal reducer. A three dimensional finite element model is developed using Algor FEA
commercial code to simulate the combined effect of external loading and dynamic as well as inertial forces on
one-cycloid disc system. This model utilizes surface-to-surface contact to define interaction between
rotating parts of the reducer assembly. The results are analyzed for the variation in stress and deformation
with respect to time for a certain simulation period. This study gives an insight of internal load sharing of
rotating parts and their capability of carrying shock loads.
