Two-stage worm gear's advantage

The valve adopts two-stage worm gear drives,the core advantages of two-stage worm gear drives in valve applications include:

1. Achieving a larger overall reduction ratio and output torque: Enabling valves requiring extremely high torque to be driven with a higher-speed, lower-power motor.

2. Smoother transmission and less impact: By distributing the large overall reduction ratio across two stages, the load on each stage is relatively reduced, and the forces and impacts during meshing are gradually mitigated.

3. More optimized and flexible structural design: Two-stage drives allow designers greater flexibility in allocating the reduction ratio and optimizing the module, number of threads, and dimensions of each worm gear.

4. Higher reliability and safety: Two-stage drives act as a "power backup system." Even if one stage experiences abnormal wear or minor damage, the other stage can still provide a certain amount of transmission capacity and self-locking function, preventing complete instantaneous failure.

Torque of the two-stage worm gear

The two-stage worm gear is a crucial component in valve drive technology. Through a more complex structure, it achieves peak performance in torque, smoothness, and reliability, making it a key technological solution for solving the most demanding valve actuation problems.
