Precision Cylindrical Gears (Spur & Helical) for Power Transmission
Donghua manufactures high-quality cylindrical gears, the most common family of gears used for power transmission between parallel shafts. This category includes both spur gears (straight teeth) and helical gears (angled teeth). As a comprehensive power transmission manufacturer since 1991, we produce precision cylindrical gears to DIN standards, offering a wide range of modules, teeth counts, and surface treatments to meet your exact requirements.
Understanding Cylindrical Gears: Spur vs. Helical
| Gear Type | Characteristics | Typical Applications |
|---|---|---|
| Spur Gears | Straight teeth parallel to axis. Simple, efficient, high precision. No axial thrust. Can be noisier at high speeds. | Conveyors, machine tools, speed reducers, material handling. |
| Helical Gears | Angled teeth. Smoother and quieter operation. Can handle higher loads. Generate axial thrust. | Automotive transmissions, high-speed machinery, industrial drives. |

At Donghua, we ensure the precision of our cylindrical gears through advanced measurement techniques. Our ability to scan the entire gear profile-including the working tooth flank, root, and bottom-at speeds of up to 7 mm/s allows us to verify critical parameters like tooth root radius and pitch deviation. This commitment to precision measurement ensures every gear meets our high standards for accurate geometry, resulting in smoother, quieter operation and longer gear life.
