A Helical Gearbox and a Worm Gearbox are both types of mechanical power transmission systems used to control speed and torque between a motor and driven equipment. A Helical Gearbox uses angled teeth cut on the gear shafts, which engage gradually and smoothly, resulting in quieter operation, higher efficiency, and better load-carrying capacity compared to spur gears. It is commonly used in heavy-duty applications such as conveyors, crushers, and mixers, where high torque and continuous operation are required. A Worm Gearbox, on the other hand, consists of a worm (screw) meshing with a worm wheel, allowing for high torque transmission with compact design and significant speed reduction in a single stage. It offers self-locking capability, preventing back-driving, which makes it ideal for lifts, hoists, and positioning systems. However, worm gearboxes typically have lower efficiency due to higher friction losses compared to helical gearboxes.
