A worm and helical gear is a special type of transmission gear that combines the characteristics of a worm gear and a spiral gear. Typically, it consists of a worm (with helical teeth) and a worm wheel (also with helical teeth). The gear system efficiently transmits power, provides high reduction ratios, and operates with reduced noise and smoothness due to the combination of the worm's design and the spiral teeth.

Product Advantages
High Reduction Ratios
One of the main advantages of worm gear spiral gears is their ability to provide high reduction ratios, especially in applications where significant speed reduction is required. It efficiently converts high-speed rotation into low-speed, high-torque output.
Smooth Operation
Thanks to the helical tooth design of the spiral gear, the engagement process is smoother compared to straight-cut gears, resulting in quieter operation and less vibration. This makes them suitable for applications requiring low-noise transmission.
Compact Design
The structure of the worm gear spiral gear is compact. Compared to other gear systems, they save space and are especially useful for designs where space is limited.
High Load-Bearing Capacity
The helical teeth of the spiral gear offer a larger contact area, which increases its load-bearing capacity. Coupled with the worm's high torque transmission, worm gear spiral gears are capable of handling heavy loads.
