Product Description


 

PRODUCT CHARACTERISTICS

 

  • Worm and Worm Wheel: The gearbox consists of a worm (a type of screw) and a worm wheel (a gear in the form of a helical gear). The worm is driven by the input shaft, while the worm wheel is driven by the worm and is usually perpendicular to the worm.

  • Gear Reduction: Worm gearboxes provide a significant gear reduction ratio in a compact size. The reduction ratio is determined by the number of teeth on the worm wheel and the pitch diameter of the worm.

  • Self-locking: One of the distinctive features of worm gearboxes is their self-locking ability. This means the gearbox cannot be backdriven easily, which provides mechanical advantage in applications where holding torque is required.

  • Efficiency: Worm gearboxes typically have lower efficiency compared to other types of gearboxes (usually around 50-90%), due to the sliding action between the teeth of the worm and worm wheel. Efficiency can vary based on the design and lubrication.

  • Applications: They are commonly used in applications where space is limited but high gear reduction is necessary, such as conveyor systems, packaging machinery, elevators, and automotive applications (e.g., steering systems).

  • Design Considerations: When selecting a worm gearbox, factors such as torque requirements, speed reduction ratio, efficiency, backlash (play between gears), and lubrication requirements need to be considered.

  • Advantages: Compact size, high reduction ratio capability, self-locking feature, and quiet operation are some advantages of worm gearboxes.
