Product Description

A double-lead worm, also known as a variable-lead worm, is primarily used to eliminate backlash in worm gearing. It is often used in structures such as indexing tables.

The working principle of a double-lead worm lies in its helix angle gradually changing along the axial direction. This characteristic allows the worm and worm wheel to generate an axial force during meshing. This axial force helps adjust the relative positions of the teeth in the worm gear, effectively reducing or eliminating backlash. This design not only improves the accuracy and stability of the transmission but also significantly enhances the system's rigidity, reducing the adverse effects of backlash. Furthermore, double-lead worms have a wide range of applications, not limited to precision indexing tables; they are also commonly found in mechanical equipment requiring high-precision positioning and transmission, such as CNC machine tools, aerospace equipment, and precision measuring instruments. Its unique performance advantages play an irreplaceable role in these high-precision fields. With the continuous advancement of manufacturing technology, the design and manufacturing precision of double-lead worms are also constantly improving, further expanding their application fields and meeting the transmission needs of more complex working conditions.
