What type of gear are R/G teeth?

R/G teeth refer to gear teeth that have a helical design. In helix gears, the teeth are cut at an angle to the axis of the gear, creating a smoother engagement between meshing gears compared to straight-cut teeth. This design allows for more gradual contact as the teeth come together, which reduces noise and vibration during operation and provides higher load capacity.

Helical gears also offer the advantage of continuous engagement of teeth during operation, which enhances the transfer of power and can lead to increased efficiency. Additionally, they allow for better alignment between gears, leading to a more stable and durable setup.

Straight cut gears, spur gears, and crowned gears do not utilize the benefits of the helical design. Straight cut gears feature straight teeth and are known for their simplicity and efficiency in lower-speed applications, while spur gears have teeth that are parallel to the axis of rotation. Crowned gears have an involute profile that can help in maintaining proper alignment by centering the load. However, none of these provide the same advantages in terms of contact and load distribution as helical gears with R/G teeth.
