There are many types of reducers. The common ones mainly include the following:
1. **Planetary reducer**:
– Characteristics: It has the advantages of high precision, high rigidity, high efficiency, high torque capacity and low backlash.
– Applications: Widely used in industrial robots, CNC machine tools, printing and packaging machinery, automated production lines and other equipment with high requirements for precision and dynamic performance.
– Examples: In the joint drive of industrial robots, the planetary reducer can ensure precise motion control and position accuracy.
2. **Gear reducer**:
– Classification: Including cylindrical gear reducer, bevel gear reducer, worm gear reducer, etc.
– Characteristics: The transmission efficiency is relatively high, the structure is relatively simple, and the work is reliable.
– Applications: Commonly used in general transmission equipment in the fields of lifting and transportation, metallurgy, mining, chemical industry, etc.
– Examples: In the lifting mechanism of a crane, the cylindrical gear reducer can achieve stable power transmission and speed regulation.
3. **Cycloidal pinwheel reducer**:
– Characteristics: Small size, light weight, large transmission ratio and relatively high transmission efficiency.
– Applications: It is more common in the stirring equipment in the chemical, pharmaceutical, food and other industries.
– Examples: The stirring reactors in pharmaceutical factories often use cycloidal pinwheel reducers to drive the stirring paddles.
4. **Harmonic reducer**:
– Characteristics: It has the characteristics of light weight, small size and high precision.
– Applications: Suitable for occasions with high requirements for space and weight, such as service robots and medical devices.
– Examples: In the operating arm of minimally invasive surgical robots, harmonic reducers contribute to achieving precise movements.
5. **Continuously variable reducer**:
– Characteristics: It can achieve continuous and smooth speed variation and has a wide speed regulation range.
– Applications: In the equipment of industries such as textiles, printing, and plastics, it is used for speed adjustment to meet different process requirements.
– Examples: In the winding equipment of textile machinery, the winding speed can be adjusted through the continuously variable reducer according to different yarn specifications and process requirements.
6. **Worm gear reducer**:
– Characteristics: It has a large reduction ratio, stable transmission, low noise, but the transmission efficiency is relatively low.
– Applications: Commonly used in elevators, winches, food machinery and other occasions that require high stability and low speed.
– Examples: In some small lifting equipment, such as household small winches, worm gear reducers can provide stable deceleration and large torque output.
