Reducer Classification
Types of gear reducers
Different types of gear reducers serve different functions, and they can be classified in various ways. By transmission method, they include spur gear reducers, helical gear reducers, and planetary gear reducers; by number of stages, they are single-stage and multi-stage reducers; by gear geometry, they comprise cylindrical gear reducers, bevel gear reducers, and bevel–cylindrical gear reducers; and by arrangement, they include expansion-type, split-type, and coaxial reducers.
There are four common types of gearboxes: worm gear reducers, planetary gear reducers, spur gear reducers, and bevel gear reducers.
Worm gear reducer
This type of right-angle reducer incorporates a worm gear, achieving a high reduction ratio of approximately 1/10 to 1/60. Worm‑gear reducers are typically used in applications requiring very high gear ratios. They feature a vertical configuration with both input and output shafts aligned vertically. The non‑reversible design of worm‑gear reducers ensures that the worm cannot drive the worm wheel, providing self‑locking capability and an additional layer of system safety. With low initial costs, high reduction ratios, and high output torque, worm‑gearboxes may represent the most cost‑effective speed‑reduction solution.
Planetary gear reducer
All‑gear reducers offer numerous advantages, including compactness, low ground clearance, high efficiency, long service life, and a high rated output torque. These gear reducers feature a coaxial configuration. The all‑gear design seamlessly combines compact dimensions with exceptional power‑transmission efficiency, with typical stage‑level efficiency losses of only about 3%. This means that most of the input energy is amplified and converted into torque, rather than being dissipated as mechanical losses. By contrast, planetary gearboxes are more complex and costly to manufacture and require specialized maintenance.
