**Gear reducers** are designed to decrease the output speed of a motor while increasing torque. This type of gearbox is common in applications where high torque is necessary, such as in conveyor systems or heavy machinery.
**Key Features:**
- Generally consists of two or more gears.
- Reduces speed while increasing torque.
- Used in various applications, including automotive and industrial machinery.

2.2 Worm Gearboxes

**Worm gearboxes** feature a worm gear and a worm wheel, providing a unique solution for converting rotational motion. They are known for their high torque output and compact design.
**Key Features:**
- Excellent for applications requiring high reduction ratios.
- Provides self-locking capabilities, making them ideal for applications where back-driving is a concern.
- Commonly used in elevators, conveyors, and material handling equipment.

2.3 Helical Gearboxes

**Helical gearboxes** utilize helical gears that operate smoothly, offering higher efficiency and lower noise levels compared to other types. They are characterized by their angled teeth, which engage more gradually.
**Key Features:**
- Offers high load capacities and torque transmission.
- Ideal for high-speed applications due to reduced friction.
- Widely used in manufacturing equipment and power generation.

2.4 Planetary Gearboxes

**Planetary gearboxes** consist of a central sun gear, multiple planet gears, and an outer ring gear. This configuration allows for high torque density in a compact design, making them suitable for various applications.
**Key Features:**
- Offers excellent efficiency and durability.
- Provides a high reduction ratio in a small form factor.
- Commonly found in robotics, wind turbines, and automotive applications.

2.5 Bevel Gearboxes

**Bevel gearboxes** are designed to transmit power at an angle, typically at 90 degrees. They are available in straight, spiral, and hypoid configurations, each offering distinct advantages.
**Key Features:**
- Enables direction change of power transmission.
- Suitable for applications requiring high-speed and high-torque capabilities.
- Used in various machinery, including automotive and heavy equipment.
