Product Description

High-Precision Internal Gear Ring for Industrial Applications

When your machinery requires precise rotational power transmission within confined spaces, selecting the right gear assembly is crucial. Luoyang Hengguan Bearing Technology Co., Ltd.'s internal gear rings offer a mature and reliable solution to meet the demands of demanding industrial applications. Our products feature teeth distributed along the inner circumference, allowing for smooth meshing with external pinions or planetary gears to create efficient, space-saving transmission systems. With over 20 years of manufacturing experience and ISO9001 certification, we offer high-precision products with diameters ranging from 50mm to 5000mm and modules from M1 to M20 and above to meet your specific torque transmission needs.

Product Details

Our products feature a high-precision involute tooth profile design. This optimized geometry ensures smooth, shock-free mating with planetary gears or pinions.

The result is higher transmission efficiency and a significant reduction in equipment noise and vibration.

We manufacture these components using premium materials, including 45# steel, 42CrMo, and 20CrMnTi. Each material is carefully selected to ensure specific mechanical properties. Depending on your operating conditions, we employ appropriate heat treatment processes to ensure ideal hardness and wear resistance.

The internal gear design offers significant advantages. The teeth are fixed within a ring structure, improving cleanliness. Internal gears offer superior lubrication compared to external gears. Most importantly, internal gears experience lower transmission contact pressure, thus reducing long-term wear.

Our production base in Luoyang, the center of China's bearing industry, is equipped with CNC vertical machining centers, CNC milling machines, machining centers, and large gear hobbing machines. This advanced equipment enables us to maintain stringent flexibility and consistent quality for every product.
