Custom Profile Gears

These gears send power between shafts that run parallel to each other. Here are the main types:
Spur Gear: The most common and simplest kind. Its teeth are straight and run along the gear’s axis. It works well in many situations, is reliable, and is used for low to medium speed things like clocks and conveyor belts.
Helical Gear: Its teeth are cut at an angle (not straight with the axis). This makes it run smoother and quieter than a spur gear, and it can handle heavier loads. But it pushes the shaft in a straight line (axial thrust), so the bearing system needs to manage that.
Double Helical Gear (Herringbone Gear): Like two helical gears put side by side, but their teeth angles face opposite ways. This cancels out the axial thrust (no more pushing the shaft).
Internal Gear: A round gear with teeth on the inside of a ring. It’s often used in small, compact setups like planetary gear systems.
Rack and Pinion: A set of two parts—one round gear (pinion) and one flat, straight gear (rack). They work together to turn rotational motion (spinning) into linear motion (moving straight). You’ll find this in car steering systems.
