Product Series Classification | ||
Gear Type | Key Characteristics | Typical Applications |
Spur Gear | Features a simple structure, easy manufacturing process, and high transmission efficiency. Transmission occurs along the axial direction; however, noise levels tend to be relatively higher at high speeds. | General machinery, automotive gearboxes, electric tools, household appliances |
Helical Gear | Equipped with inclined teeth, ensuring smooth meshing, low operational noise, and high load-bearing capacity. Note that axial thrust is generated during transmission, requiring appropriate thrust bearing configurations. | Automotive engines, industrial reducers, precision machine tools, wind turbines |
Bevel Gear | Designed for intersecting shaft transmission, available in various tooth profiles (straight, spiral, hypoid). Boasts a compact structure, facilitating space-saving installations. | Automotive differentials, machine tool worktables, agricultural machinery, marine propulsion systems |
Worm Gear | Offers a large transmission ratio, inherent self-locking performance, and smooth operation. The trade-off is relatively low transmission efficiency, making it suitable for low-speed applications. | Lifting machinery, conveyor systems, precision positioning devices, medical equipment |
Material and Heat Treatment Parameters | |||
Material | Heat Treatment Method | Hardness (HRC) | Applicable Scenarios |
45# Steel | Quenching and Tempering | 22 - 28 | General load, low-speed transmission applications such as general machinery accessories and light-duty gearboxes. |
40Cr | Quenching and Tempering / Carburizing and Quenching | 28 - 32 / 58 - 62 | Medium load, medium-speed transmission scenarios, including automotive intermediate gears, industrial reducer gears, and mechanical equipment transmission systems. |
20CrMnTi | Carburizing and Quenching | 58 - 64 | High load, high-speed transmission, and precision gear applications, such as automotive main reducers, high-precision machine tool gears, and robotics transmission components. |
Stainless Steel 304 | Solution Treatment | 18 - 22 | Corrosive environments, including chemical processing equipment, food machinery, marine equipment, and medical devices. |
Brass H62 | Annealing | 80 - 100 HB | Light load, low-noise transmission applications, such as instrument gears, small household appliances, and precision electromechanical products. |
Common Gear Technical Parameters | ||
Parameter | Description | Range of Our Products |
Modulus (m) | A fundamental parameter that determines the size, strength, and load-bearing capacity of gear teeth. A larger modulus indicates higher load-bearing capacity. | 0.5 - 20 mm |
Number of Teeth (z) | Affects the transmission ratio, gear size, and meshing smoothness. A reasonable number of teeth ensures optimal transmission performance and avoids undercutting. | 10 - 200 |
Pressure Angle (α) | A key parameter influencing meshing performance, load distribution, and tooth strength. The standard pressure angle is 20°, which balances performance and manufacturability. | 20° (customizable 14.5° for special applications) |
Helix Angle (β) | Exclusive to helical gears, it affects meshing smoothness, axial thrust, and load-bearing capacity. A larger helix angle improves meshing performance but increases axial thrust. | 5° - 45° |
Precision Grade (ISO) | Determines the machining accuracy, including tooth profile accuracy, pitch accuracy, and runout tolerance. Higher precision grades ensure better transmission accuracy and lower noise. | 5 - 12 (Grade 5 for high-precision applications, Grade 12 for general-purpose applications) |
Maximum Speed (n_max) | The maximum allowable operating speed under standard working conditions, which is constrained by material strength, lubrication conditions, and centrifugal force. | Up to 10000 r/min (varies by gear type and size) |
Rated Load (T_rated) | The maximum allowable tangential load on the gear's pitch circle during continuous operation, which is determined by material strength and tooth geometry. | Up to 500 kN |
