| dc.description.abstract | Rotavator is one of the tillage machine which is used in arable field preparing the seedbed preparation directly. Rotavator is attached to three point linkage system of a tractor and it is driven by the tractor power take off (PTO). Rotavator construction has a gear box that changes motion direction with 90° from tractor PTO, transmission gears for rotation velocity and a rotor shaft which placed as horizontal to soil for blending. In this work transmission gear train of a rotavator is analyzed considering bending stresses, contact stresses and mode shapes. The effect of reducing thickness of web in gears is also studied. The reduced thickness of web resulted in redistribution of stresses and led to decrease in magnitude of localized stresses. Simple design modifications, reducing the thickness of web of gears are also implemented after successful validation of finite element solution. | en |
