Types of double enveloping worm machines

Double enveloping worms come in various types, each with its own applications and advantages. The following types of double enveloping worm gears are commonly used.

• Cylindrical Double- Enveloping Worm Gear: The most popular type of double enveloping worm gear is the cylindrical double-enveloping worm gear. It has a cylindrical worm shaft and a gear with a socket-type tooth profile that wraps around the worm. The design provides high efficiency and load-carrying capacity.
• Cylindrical Double-Enveloping Worm Gear with Interceptors: This variation of the cylindrical double-enveloping worm gear includes interceptors (partial gears) that are positioned between the main driving and driven gears. The interceptors improve the load distribution and gear efficiency.
• Non-cylindrical Double-Enveloping Worm Gear: The non-cylindrical double-enveloping worm gear has different-shaped worms and gears. Examples include helical and hypoide double-enveloping worms. Non-cylindrical double-enveloping worms offer a larger contact area, higher torque capacity, and smoother operations than the cylindrical type.
• Cylindrical Double-Enveloping Worm Gear with True Herringbone Gears: This gear uses herringbone gears to mesh with the double-eneveloping worms. The herringbone gear eliminates gaps between the teeth, resulting in high load-carrying capacity, efficiency, and low noise operations.
