| Gear Hobbing Features | Worm Gear Cutting: - Worm Gears are similar to screws, with teeth in a 360 degree profile. They have a high gear ratio in a small space. Bevel Gear Cutting: - Bevel gears are conical in shape but do not extend to their vertex. Rack and Pinion Gear Cutting: - Rack and pinion gears have a rack, or toothed rod operated by a pinion gear converting torque into a straight line movement. Helical Gear Cutting: - Helical gears have angled teeth that provide for a slower, smoother motion. |
