Answer
The best answer is **Planetary reduction gear**.
Solution
The best answer is:
**Planetary reduction gear**
**Explanation:**
A Gear Reduction Unit typically refers to a mechanism that reduces the input speed while increasing torque. A **planetary reduction gear** system is an effective and compact way to achieve this. It consists of a central sun gear, planet gears, and a ring gear, allowing for high torque density and efficient power transmission. This makes it the most appropriate description among the provided options.
- **Single-speed forward gear and reverse gear**: This describes a simple gearbox that allows for one forward gear ratio and a reverse direction but doesn't specifically address gear reduction.
- **Three-speed gear reduction**: This implies multiple gear ratios but doesn't specify the mechanism, making it less precise than the planetary reduction gear description.
**Answer:** Planetary reduction gear
