1) Description of Helical gears
Helical gears are power transmission instruments primarily utilized to reduce speed and increase torque
between turning shafts. Fundamentally, they can be divided into two forms, those that transmit energy
between parallel parts and those that transfer power between non-parallel components, typically introduced
as cross-axis gears. While a helical gear in section view has the identical involute tooth shape like spur gear,
it is cut at an angle to the circulation of the gear blank. This angle is introduced as the helix angle.
