The gear ratio of this type of gear reducer can vary widely depending on the specific design and application requirements. Typical gear ratios range from 3:1 to 100:1. A lower gear ratio, such as 3:1 oder 5:1, provides a relatively smaller speed reduction and torque multiplication, suitable for applications where a higher output speed is still needed. Higher gear ratios like 50:1 oder 100:1 are used when a significant increase in torque and a substantial reduction in speed are required.
The gear ratio is determined by the number and configuration of the planetary gear stages. Each stage contributes to the overall gear ratio multiplication. For example, a two – stage planetary gearbox can achieve a higher gear ratio than a single – stage one.
Torque Capacity
High – torque capacity is a key feature. Torque ratings can range from a few hundred Newton – meters (N·m) to several thousand N·m. The exact torque capacity depends on factors such as the size of the gears, the material used (usually high – strength alloy steel), and the quality of the bearings and other load – bearing components. For a medium – sized industrial application, the torque capacity might be around 1000 – 2000 N·m, while for heavy – duty applications like large – scale mining equipment, it can exceed 5000 N·m.
The torque – handling ability is also related to the gearbox's internal design. Reinforced shafts, thick – walled housings, and high – load – capacity bearings are used to ensure reliable torque transmission.
