SE series slew drives are widely used in multiple industrial fields and engineering application scenarios due to their high precision, large torque and stability. The following are some common application scenarios of SE series slew drives:
Industrial machinery: SE series slew drives are commonly used in the field of industrial machinery, such as CNC machine tools, injection molding machinery, mixing equipment, etc. Its high precision and high torque make it ideal for production equipment that requires rotational motion, such as positioning, rotating and machining parts during manufacturing.
Solar tracking system: In the solar industry, SE series slew drives are widely used in solar tracking systems to adjust the angle of solar panels to maximize the absorption of sunlight. Such applications require high precision and reliability to ensure that the solar panels maintain their optimal orientation during daily and seasonal changes.
The structural design of the SE series slew drive usually includes the following key components:
| Model | Output Torque | Tilting Moment Torque | Holding Torque | Gear Ratio | Tracking Precision | Weight | Drawing |
|---|---|---|---|---|---|---|---|
| SE9 | 6.5 KN.m | 33.9 KN.m | 38.7 KN.m | 61:1 | 0.17° | 49kg | |
| SE9 | 4794 lbf.ft | 25×10³ lbf.ft | 29×10³ lbf.ft | 61:1 | 0.17° | 49kg |
