Analysis of the stress-strain state under static load of face wave kinematic reducer
The purpose of the article is development of a static finite element model for a face wave kinematic reducer using the finite element analysis software system ANSYS. This model built using the Solidworks software will predict the distribution of stresses and displacements of the reducing gear under investigation. Creation of the model involves the use of three-dimensional finite elements such as solid cylinders and contact surface elements for simulating the engagement between gear teeth. Due to the complexity, the teeth were not modeled. In this case, the contact of the teeth is adopted as the contact of the gear surface. It is complicated to calculate stresses in gear engagements due to the engagement geometry and application of a large number of correction factors. This leads to inaccurate results that differ from the actual values. One of the best ways to improve the precision characteristics of gearing is computer simulation. Thus, according to the calculation results of the stress-strain state a method for checking calculation of the contact and bending strength of the studied reducing gear is proposed.
