Finite element stress analysis of three-stage gear box

The stress analysis of the three-stage gearbox is carried out by finite element method using Ansys commercial program. triple reduction helical made AISI 5115 Steel (16MnCr5) and 8620. Static structural rigid dynamic analyzes are performed in this work. a transmitting 0.5 kW at 1390 rpm with ratio 127.99:1. After setting boundary conditions for gears, performed. Rotational velocity given to rotating gears static analysis. Analyzing these types gearboxes be produced enables product more consciously optimum design parameters its right safety coefficients. analysis, also modal option software. mode shape natural frequency performed, operation values calculated considering input output gearbox. These compared normal operating condition see if there will any resonance gear box during conditions.
