“Curved Surface Meshing Specialist” in Worm Gear Transmission Technology
The arc - tooth enveloping worm has multiple advantages. First, its carrying capacity is 3 - 5 times that of ordinary worms, reducing heavy - duty equipment downtime and maintenance costs. Second, it has excellent transmission smoothness. Multi - tooth meshing leads to a large transmission overlap coefficient, weakening inter - tooth impact and vibration. The operating noise is 5 - 10 dB lower than ordinary worms, suitable for high - smoothness scenarios like radars and missile launchers. Third, it has a compact structure. When transmitting the same power, its center distance can be 20% - 30% smaller than ordinary worm pairs, saving installation space.
However, it has a high cost. First, the manufacturing process is complex, requiring specialized equipment and tools with strict arc precision control and machined tool adjustment requirements. Second, the manufacturing cost is 5 - 10 times that of ordinary cylindrical worms. Third, it is sensitive to installation errors, needing high - precision instruments for calibration. Fourth, design and modification are complex, demanding high professional capabilities from designers.
Due to these, its application fields are concentrated in harsh scenarios where performance takes precedence over cost, such as metallurgical, mining, port, chemical, marine, and military industries.
In summary, the arc - tooth enveloping worm, through the design of “arc tooth profile + double enveloping”, breaks through the performance ceiling of ordinary worm drives, achieving “multi - tooth, large - area contact”. Although costly, its performance advantages in core transmission links can offset the cost disadvantages, truly deserving the title of “the pearl in the crown of worm gear transmission technology”.
