The teeth of the internal gear are distributed on the inner surface of the hollow cylinder, which is in sharp contrast to the convex tooth profile of the conventional external gear. During the transmission process, the internal gear and the external gear mesh with each other, which can not only realize power transmission, but also change the direction of movement. And because the two rotate in the same direction, it effectively reduces the space occupied and makes the mechanical structure more compact.
steel spur gears Detail
| Product Name | steel spur gears |
| Product Material | Made of high-strength carbon structural steel or alloy structural steel (such as 20CrMnTi), it has excellent impact resistance |
| Product Process | Through the processes of forging blank, rough machining of tooth shape, carburizing and quenching heat treatment strengthening, fine grinding of tooth surface, etc., the tooth shape accuracy and heat treatment hardness are controlled. |
| Surface Treatment | Surface treatment includes carburizing and quenching, hard plating or blackening (blueing) treatment to form an oxide film |
| Customizable Products | Gears / Sprockets / Worms / Shafts / Rack Bars / Bevel Gears, etc. |
Product Advantages
High strength
The steel material is hard and can withstand large torque and load.
Good wear resistance
The surface hardness is improved after heat treatment, which reduces the wear in long-term operation.
High transmission efficiency
Standard tooth shape design, small energy loss during meshing, stable transmission accuracy,
Mature technology
perfect processing technology, controllable cost

1. What kind of steel do you use for your steel spur gears?
We use 45 high-quality carbon structural steel or 20CrMnTi alloy carburizing steel, which is quenched and tempered or carburized and quenched.
2. Can it meet the needs of precision transmission?
We can customize 5-6 grade high-precision gears according to needs to meet the precision transmission requirements of CNC machine tools, automation equipment, etc.
3. What are the minimum and maximum moduli?
The conventional production range is modulus 0.5-8mm. Special needs can be customized to smaller (modulus 0.3mm) or larger (modulus 12mm) specifications, which require specific evaluation of production process and delivery cycle.
