Slew drive assemblies are rotational mechanisms designed to support radial, axial, and tilting moment loads. They consist of a slewing ring (slewing bearing), worm gear, housing, and a motor or hydraulic drive. These assemblies convert rotary or linear motion into controlled rotational movement, often used in applications that require high torque and precise positioning.
Key components of a slew drive assembly include:
- Slewing Bearing: Provides the rotational interface, capable of handling various loads.
- Worm Gear: Engages with the slewing bearing to drive rotation.
- Housing: Protects internal components and ensures alignment.
- Motor or Hydraulic Drive: Powers the assembly, enabling rotation.
| Model | Output Torque | Tilting Moment Torque | Holding Torque | Gear Ratio | Tracking Precision | Weight | Drawing |
|---|---|---|---|---|---|---|---|
| W14 | 10.8 KN.m | 71.2 KN.m | 48 KN.m | 86:1 | ≤0.13° | 62kg |  |
| W14 | 7970 lbf.ft | 52.6×10³ lbf.ft | 35×10³ lbf.ft | 86:1 | ≤0.13° | 62kg | |
Slew drive assemblies are commonly used in equipment like cranes, solar trackers, wind turbines, and industrial machinery. Their ability to deliver smooth and reliable rotation with high load-bearing capacity makes them essential for heavy-duty applications.
