Internal bevel gears are bevel gears with tooth surfaces located on the inside of a cone. They are usually paired with external bevel gears (tooth surfaces on the outside of the cone) to transmit power and motion between two intersecting shafts (the angle between the shafts is usually 90°, but can also be designed as needed). They are widely used in transmission systems such as automobiles, machine tools, and construction machinery.
internal bevel gear Detail
| Product Name | internal bevel gear |
| Product Material | Available in 20CrMnTi, 40Cr, and 304 stainless steel, these materials can be tailored to meet diverse application requirements, including high toughness, corrosion resistance, and high-load resistance. |
| Product Process | Utilizing precision CNC machining, key parameters such as module and number of teeth are precisely controlled, supporting both standard and customized production to ensure meshing accuracy and transmission stability. |
| Surface Treatment | Options include blackening, galvanizing, and carburizing/quenching, ensuring both rust prevention and increased hardness. Suitable for use in dry, humid, and high-salt-fog environments. |
| Customizable Products | Gears / Sprockets / Worms / Shafts / Rack Bars / Bevel Gears, etc. |
Product Advantages
High Space Utilization
The concave tooth surface design allows for nested layouts when paired for transmission, eliminating the need for additional installation space.
High Load Capacity
Compared to external bevel gears of the same specification, internal bevel gears have a greater tooth root thickness.
Excellent Transmission Smoothness
The relative sliding speed during tooth meshing is low, resulting in less impact and noise.
High Transmission Efficiency
Meshing clearance is easily controlled, energy loss is minimized, and reverse transmission performance is stable.

FAQ:
Q: What shaft angles and module ranges do your internal bevel gears support?
A: We typically support a 90° shaft angle (the most common), but we can also customize special shaft angles of 45°-120° upon request. The module range is 1-20mm. For larger/smaller modules (e.g., 0.5mm or 25mm or larger), we can provide drawings for custom design.
Q: What material options are available for internal bevel gears? What applications are suitable for different materials?
A: Mainstream materials include 20CrMnTi (automotive/construction machinery, high toughness and impact resistance), 40Cr (general machinery, cost-effective), 304 stainless steel (food/medical equipment, corrosion resistance), and high-strength alloy steel (heavy equipment, high load resistance). We can recommend suitable materials based on the purchaser's operating environment (e.g., exposure to acids and alkalis, load size).
Q: When pairing internal bevel gears with external bevel gears, do I need to provide the external bevel gear parameters?
A: Yes. To ensure the matching of the clearance and center distance of the paired transmission, the purchaser is required to provide key parameters such as the module, number of teeth, pitch cone angle, and tooth addendum coefficient of the external bevel gear. If the purchaser only needs to purchase the internal bevel gear separately, they can also provide the design drawings of the complete transmission system and we will match and process it.
