Custom Durable Transmission Gears with Multiple Planetary Gear Offering High Transmission Efficiency

Internal Gear Ring Description

From the perspective of planetary gearing core adaptation, the internal gear ring is a transmission component featuring a ring-shaped structure with teeth distributed along its inner bore surface. It constitutes a core element of the planetary gear mechanism, working in concert with the sun gear and planet gears to achieve power transmission and reduction/increase functions.

Key Features

Characterised by an overall annular configuration, featuring high precision internal gearing (requiring accurate meshing with multiple planetary gears) and robust structural rigidity; Advantages include a broad gear ratio range (achievable by varying the number of planetary gears or adjusting tooth ratios), uniform load distribution (achieved through simultaneous meshing of multiple planetary gears), high transmission efficiency (typically reaching 96%-98%), and seamless compatibility with planetary transmission systems, thereby simplifying the overall transmission structure.

Applications

Suitable for equipment dominated by planetary transmission systems, such as planetary gear mechanisms in automotive automatic transmissions (where the ring gear serves as a fixed or rotating component), industrial robot joint reducers (e.g., the ring gear in RV reducers), gearboxes in wind power equipment, hydraulic motor transmission systems in construction machinery, and spindle reduction mechanisms in precision machine tools.
