A Helical Gear is typically toothed wheels that mesh with one another, allowing for the transfer of rotation and torque between the shafts. Helical Idler Gear is a type of Gear that is used to transmit rotational power between two parallel shafts and it does not change the direction of rotation between the input and output shafts, but rather it simply transfers the rotational power from one shaft to the other.Attributes:• Can handle high torque and rotational speeds• Manufactured to precise specifications and are built for durability and reliabilityApplications:A helical Gear is used to transfer power to the Other drive accessory from the Crankshaft output shaft.
