💡 How do helical gears improve performance in drive systems? Helical gears mesh at an angle to create steady contact during rotation. - They cut down on vibration compared to straight spur gears. - This design supports higher loads while keeping things quiet. - You get better torque transfer in machine tools and vehicle drives.
