Abstract
In this paper, the effects of profile shift in cylindrical helical gear mechanisms have been investigated with numerical and analytical calculations. The mathematical model for computer simulation of gears has been designed and the numerical calculations have been carried out. Analytical calculations have been made with an excel program which was designed at different profile shift coefficients for a selected mechanism. Analytical calculations of the same mechanism have been verified by using ANSYS 14.5. The results of analytical and numerical solutions have been compared to profile shift coefficients.

Profile shift coefficient for each mechanism was implemented by increasing or decreasing x = 0.1 for models used in the analytical solution
Summary
Cylindrical gears are essential machine elements and widely used in many fields, such as wind power, coastal ships, automotive products, and general gear boxes. The helical gears offer considerable advantages for high speed and heavy-duty gear drives. For helical gears the total contact ratio is higher owing to the axial tooth overlap. Tend to have greater load-carrying capacity compared with spur gears which material, quality of manufacture, lubrication, type of loading, and other factors are the same. They possess the ability to a much smoother and quieter running [1] [2].
