Helical gears are currently being used increasingly as a power transmitting gear owing to their relatively smooth and silent operation, large load carrying capacity and higher operating speed. Gears are use to transmit power and motion from one shaft to another. Keywords: Helical Gear, Stress Calculation, Bending Stress, Contact Stress, Finite Element Analysis.
The stresses found from ANSYS results are compared with those from theoretical and AGMA values. It is therefore observed that the maximum bending stress decreases with increasing face width. Study is conducted by varying the face width to find its effect on the bending stress of helical gear. For contact stresses Hertz and AGMA contact equation are used. Analytical method of calculating gear bending stresses uses Lewis and AGMA bending equation.
HELICAL GEAR DESIGN SOFTWARE SOFTWARE
To estimate bending and contact stresses, 3D models are generated by modeling software CATIA V5 and simulation is done by finite element software package ANSYS 14.0.
The involute profile of helical gear has been modeled and the simulation is carried out for the bending and contact stresses and the same have been estimated. This paper investigates finite element model for monitoring the stresses induced of tooth flank, tooth fillet during meshing of gears. Thus, analysis of stresses has become popular as an area of research on gears to minimize or to reduce the failures and for optimal design of gears. The bending and surface strength of the gear tooth are considered to be one of the main contributors for the failure of the gear in a gear set. Gears are one of the most critical components in mechanical power transmission systems.
