Medium Duty Gear Slewing Drive SP-M 0641 High Torque Precision for Industrial Rotation

What is Medium Duty Gear Slewing Drive SP-M 0641

Medium Duty Gear Slewing Drive SP-M 0641 is an engineered rotary drive solution integrating high-capacity spur gearing and structural support for heavy-duty industrial machinery. Featuring a 6 mm module system with 123-tooth wheel gear (Z2) and 15-tooth pinion (Z1), it achieves an 8.2:1 reduction ratio to generate 15,030 Nm maximum torque (Md max). The hardened alloy steel gears undergo precision grinding for optimal contact patterns, housed within a rigid structure supporting 895 kN axial static load and 380 kN radial static load. Its IP65-rated sealing provides complete environmental protection while offering direct interchangeability with IMO equivalent products. This integrated unit combines torque transmission, axial/radial load support, and precision motion control in a single compact assembly, reducing mechanical complexity by eliminating external bearing systems.

Selecting Couplings for Spur Gear Slewing Drives

Proper coupling selection is critical for SP-M 0641 performance and longevity:

Torque Capacity: Coupling must handle 1.5x maximum input torque (calculated from Md max and ratio)

Zero-Backlash Requirement: Disc-type couplings maintain positional accuracy during reversals

Misalignment Compensation:

Angular: ≥1.5° for installation tolerances

Parallel: ≥0.5mm for thermal expansion effects

Axial: ≥±2mm for shaft displacement

Torsional Stiffness: High rigidity (>10⁴ Nm/rad) prevents oscillation during acceleration

Environmental Compatibility: Stainless steel construction required for outdoor/corrosive environments

Maintenance-Free Operation: Laser-cut metal disc packs outperform elastomeric elements

Safety Factor: DIN 740 standards require minimum SF=2 for shock loads

For SP-M 0641’s 11550 Nm nominal torque, recommend ISO 9001-certified disc couplings with 18,000+ Nm rated capacity and IP67 protection.

Energy Efficiency Ratio of Medium Duty Gear Slewing Drive SP-M 0641

The SP-M 0641 achieves industry-leading efficiency through advanced engineering:

Ion-Nitrided Gear Surfaces: Reduced coefficient of friction (μ<0.05) through surface hardening

Optimized Tooth Profile: Ground involute geometry achieves 98.7% meshing efficiency

Low-Drag Sealing: Triple-lip PTFE seals reduce rotational resistance by 40%
