This is a 3D CAD model of a helical gear shaft assembly. The design features two parallel shafts, each equipped with helical gears for smooth and efficient power transmission. The assembly is supported by a robust base and precision blocks, which provide alignment and stability for the rotating shafts. The helical gears are designed to reduce noise and vibration while transmitting torque between shafts at a specific angle. This configuration is commonly used in mechanical power transmission systems, gearboxes, and industrial machinery.
