About Helical Gear
Helical gears can transmit energy between parallel or perpendicular axes through the use of helical teeth. They are designed to distribute pressure gradually along the whole tooth. Because of their tooth inclination, helical gears run smoother and quieter than other gears and are able to carry heavy loads efficiently. Due to the gradient of the teeth and the pressure applied, these gears are subject to axial thrust. This can be remedied by the use of thrust bearings and specialized lubricant.

Helical Bevel Gears Information
Helical bevel gears are available in two teeth configurations: left handed and right hand.
Helical bevel gears transmit energy through two axial configurations: parallel and perpendicular.
In parallel-axis helical gears the two opposite-hand gears provide quiet operation and high load capacity. These helical gears must be of opposite hands.
In perpendicular-axis helical gears, also called skew gears, two same-hand gears transmit energy through a 90° angle. The limited tooth contact of this configuration constricts work load. This type of helical alignment is comprised of two same-hand gears.
Helical Bevel Gear Application
Power, velocity and torque
Power, velocity and torque consistency and output peaks of the gear drive so the gear meets mechanical requirements.
Inertia of the gear through acceleration and deceleration. Heavier gears can be harder to stop or reverse.
Precision requirement of gear, including gear pitch, shaft diameter, pressure angle and tooth layout.
Gear lubrication requirements. Some gears require lubrication for smooth, temperate operation and this is especially true for helical gears.
Noise limitation. Commercial applications may value a smooth, quietly meshing gear. Helical gears offer quiet operation.
Vibration and shock resistance. Heavy machine loads or backlash, the deliberate surplus space in the circular pitch, may jostle gearing.
