Ring bevel gears are core components of high-ratio powertrains. They utilize an internal ring gear cone structure and are suitable for planetary transmissions, differentials, and other applications. They are widely used in heavy-duty trucks, construction machinery, wind turbines, and mining machinery. The ring gears are integrally forged and subjected to high-precision CNC machining, achieving a tooth profile consistency error of ≤0.02mm. They enable simultaneous engagement of multiple teeth and transmit torques of 5,000-50,000 Nm. Customizable inner diameters and modules are supported, and high-strength alloys are commonly used. After heat treatment, the tooth surface hardness reaches HRC56-60, resulting in excellent core toughness and the ability to withstand shock loads. These gears provide a stable, low-loss power transmission solution for heavy-load, low-speed, high-torque transmission systems.

FAQ:
How is the meshing accuracy of the inner ring gear of a bevel gear and the matching pinion gear guaranteed?
Machined to GB/T 11365 Grade 5 precision, meshing tests with the matching pinion gear are performed before shipment to ensure contact patch ≥75% and side clearance meets design requirements (0.15-0.3mm).
Gears are prone to tooth spalling under heavy loads. What are the solutions?
Using 20CrNiMo alloy material and deep carburizing (carburizing depth 2.5-4mm), the tooth surface hardness reaches HRC58-60, which reduces the risk of spalling. Extreme-pressure industrial gear oil is also recommended for lubrication.
What is the lead time for customizing large inner diameter (over 1000mm) bevel gears?
Specialized tooling is required for large custom parts. The MOQ is 10 pieces, and the lead time is 25-30 days. For batches of 50 or more, this can be reduced to 20 days.
How can I determine if a gear is compatible with my equipment's differential?
Please provide the equipment's differential housing inner diameter, input torque, transmission ratio, and matching pinion module/number of teeth. We can then match or customize an appropriate model accordingly.
