NOV 650 Ton Top Drive
There are distinct benefits that differentiate our top drive upgrade package versus third parties simply installing new motors with higher horsepower. The upgrade is less expensive than installing new motors, provides significant improvements to performance, and ensures customers are receiving the quality and experience of the OEM. We collaborated with three engineering partners to conduct a comprehensive analysis of the TDS-11SA gearbox, allowing us to determine how stress and fatigue would be affected by the increase in horsepower.

To maintain the proven service life and design safety factor of the TDS-11SA while still enabling the upgrade, major internal changes were necessary to the gearbox.
Compound and pinion gears and the bull gear mounting all required changes to accommodate the loads from the increase in power.
Bearing sizes and housings, as well, had to be adjusted to accommodate the increased load.
The gear box cover required new casting and machining to accommodate changes to the bearing.
