CVT ratio * Gear reduction ratio Mt = 19.6 * 3 * 7.54Д«asic dimensions of Gear are given:- Module(m)=2.5 The final torque on gear is:- Mt torque input at gear Torque is transferred from engine to gearbox after reduction from CVT. Its specifications are given in Table 2.Д¬ontinuous Variable Transmission (CVT) is used as constant reduction between engine output and gearbox input. The properties are as in Table 1.Д®ngine used here is Briggs and Stratton engine, Model 19(Fig. We have taken AISI 4340 for its high strength. Materials commonly used are AISI 4340, EN 353, etc. Material for Gear is chosen based on yield strength of material. To simulate gear on SOLIDWORKS and ANSYS. To remove material and optimize weight of spur gear. To model the spur gears on SOLIDWORKS using toolbox spur gear. To calculate the theoretical forces on spur gear by conventional formulas. The vehicle this gear is designed for uses a Engine power source with CVT. the basic knowledge of transmission is seen by an engineer skill to design a gearbox of required strength and maintain lightweight. In college projects like SAE BAJA, SUPERA, etc. Weight of gears in gearbox becomes a constant factor of vehicle weight as whole. Transmission assembly are stated: Simple Gear train, Compound Gear train, Planetary, etc.

Gears are commonly used in Transmission of Automobiles via Gearbox.

Gears of different types: Spur Gear, Helical Gear, Bevel Gear, Worm and Wheel Gear. Gear is used gain mechanical advantage in power transmission. The result shows the difference in weight and factor of safety between optimized and un-optimized gear models. After it, simulation on SOLIDWORKS and ANSYS is done giving input values from calculation. Gear weight is optimized by material removal from specific region. The gear is designed using SOLIDWORKS Toolbox. The given values of forces, torque and factor of safety of gear are calculated in accordance to custom vehicle.
