Custom Durable Internal Spur Gear Featuring Overload Capacity in Construction and Mining Equipment

1) Descriptions of Internal Spur Gear

From the perspective of heavy-duty stable meshing, internal gears are high-strength components specifically engineered for demanding load conditions. They transmit substantial torque through the meshing of their internal tooth surfaces with external gears, maintaining stable transmission performance under high-load environments.

2) Features of Internal Spur Gear

Characterised by high root strength (the root thickness of internal gears is 20%-30% greater than that of external gears of the same specification), a large tooth surface contact area, and the ability to withstand greater radial loads; Advantages include robust overload capacity, reduced susceptibility to root stress concentration fractures, stable transmission efficiency (maintaining over 95% efficiency under heavy loads), and mutual cancellation of radial forces during internal meshing, thereby lowering load requirements on supporting structures.

3) Applications of Internal Spur Gear

Suitable for heavy-duty equipment subjected to high loads, such as loader gearboxes in construction machinery (internal gears transmitting high torque), ball mill drive systems in mining machinery (internal gears adapted for heavy-load, low-speed operation), reduction mechanisms in large vessel propulsion systems, metallurgical equipment (e.g., auxiliary drive gears in rolling mills), and drive axle transmission components in heavy-duty trucks.
