Cylindrical Shape : Like straight gears, helical gears are cylindrical, but their tooth orientation allows for more efficient power transfer. Handedness : Helical gears are either right-handed or left-handed , depending on the direction of the helix. Mating helical gears must have opposite handedness to mesh correctly.

Advantages Over Straight Gears Smoother Operation : The angled teeth engage incrementally, reducing impact and vibration during rotation. This results in quieter operation, a critical benefit in applications where noise is a concern (e.g., automotive transmissions, industrial machinery).

Higher Load Capacity : The gradual engagement distributes force across more tooth surface area, allowing helical gears to handle heavier loads than straight gears of the same size.

Greater Efficiency : Reduced friction and smoother meshing improve overall transmission efficiency, making them suitable for high-speed applications. Variants Double Helical Gears (Herringbone Gears) : Two sets of helical teeth with opposite angles, cancelling out axial thrust.

They are used in heavy machinery but are more complex to manufacture. Skew Gears : A type of helical gear where shafts are non-parallel and non-intersecting, enabling power transfer between misaligne d axes.
