Difference Between Backlash Worm Gears And Double Lead Worm Gears

2024-01-22

Press Release | January, 2024




Backlash worm gears and double lead worm gears are two different types of worm gears that have distinct characteristics and applications.



1. Backlash Worm Gears:


- Backlash refers to the amount of play or clearance between the mating teeth of the worm and the gear in a worm gear system.


- Backlash worm gears have a certain amount of clearance between the worm and gear teeth, which allows for smoother operation and reduces the risk of binding or jamming.


- They are commonly used in applications where precise positioning and smooth motion are required, such as robotics, CNC machines, and precision instruments.


- The backlash in these gears can be adjusted or minimized to achieve higher accuracy, but it may require additional measures like using preloaded bearings or adjusting the gear mesh.

2. Double Lead Worm Gears:



- Double lead worm gears have two threads or starts on the worm, whereas a standard worm gear has only one thread.


- The double lead design increases the lead angle, which results in a higher gear ratio and faster speed of the driven gear compared to a standard worm gear.


- These gears are often used in applications where high speed and high torque transmission are required, such as heavy machinery, conveyor systems, and power transmission equipment.


- However, the double lead design can also increase the backlash in the gear system, which may affect precision and accuracy in certain applications.

In summary, backlash worm gears are preferred for applications that require precise positioning and smooth motion, while double lead worm gears are used for high-speed and high-torque applications. The choice between the two depends on the specific requirements of the application and the trade-off between accuracy and speed.
