Worm Gear: Advantages and Disadvantages

Advantages and Disadvantages of Worm Gear?

A worm gear is a machine tool that is used to create gear teeth. It consists of two sprockets connected by a shaft and are driven by an external gear or spur. The most common application for the worm drive is in industrial applications, where they are used to transfer power from one mechanism to another.

Advantages of worm Gear:

  1. High Performance
  2. Low Noise Level
  3. Energy Saving 
  4. It is smooth and simple in design.
  5. Low Maintenance Cost 
  6. Low Maintenance Time 
  7. Low Weight (Weighs less than 1/3rd of an equal-sized spool).
  8. It is Durability and Reliability.
  9. Performance advantages of worm gears are huge. 
  10. It can provide much higher torque than other types of gear. 
  11. Power and Speed you need to turn the shaft with a single gear can be achieved easily. 
  12. It allows you to use low-cost materials in creating your gear train, which makes manufacturing more affordable. 
  13. Worm gears provide superior durability over a conventional worm.
  14. It is one of the most reliable transmissions.
  15. Longer transmission life span.
  16. Highly efficient and durable, as compared to other mechanical transmissions.

Disadvantages of Worm Gear:

  1. This is not as efficient as spur gears or helical gears when turning at high speeds because the resistance from friction between the teeth can increase with speed. 
  2. They are quite expensive compared to regular transmissions and need constant maintenance.
  3. It is heavy compared to other gears.
  4. They are more rigid than spur gears, so you need to make sure that the surfaces you have machined will not become too brittle as time goes on.
