Frequently Asked Questions (FAQs)
1. What are the different types of internal gears?
Internal gears come in two types: those with teeth parallel to the axis and those with teeth formed in a helix shape. However, gears with teeth parallel to the axis are more commonly used.
2. What machines use internal gears?
Internal gears are commonly used in planetary gear box applications due to their advantages such as low vibration, high speed reduction ratio, and cost-effectiveness. They can also be applied in other situations where their unique characteristics are beneficial.
3. What are the advantages of internal gears?
Internal gears offer the advantage of reliability as all the moving parts responsible for shifting are contained within a sealed unit, such as a hub. This protects them from water, dirt, road salt, and grime, ensuring their longevity and performance.
4. How are internal gears cut?
Internal gears are typically manufactured using the shaping process with a pinion cutter. Other methods such as hobbing, milling, and shaping with a rack cutter are primarily used for external gears.
