Product datasheets
- Double-enveloping worm reducer envelope drawings
- Slewing drive torque and ratio range sheet
- Servo reducer backlash inspection notes
Solar tracker rows, radar pedestals and heavy slewing axes need reducers that hold position under reversing load. We specify double-enveloping worm gearboxes, slewing drives and repair kits with ratio, backlash and lubricant data exposed before quotation.
4,000-1,500,000 Nm holding torque - AGMA 6034 - CE 2006/42/EC
| Engineering parameter | Solar tracker slewing axis | Radar or defense positioner |
|---|---|---|

| Typical output speed | 0.05-1.2 rpm | 0.01-0.8 rpm |
| Backlash target | Controlled by ratio and preload review | Documented inspection record per axis |
| Gear verification | AGMA 6034 design notes, ISO 6336 load check | AGMA contact pattern report plus MIL-STD-810 test summary when specified |
| Environmental package | IP65 seals, UV-stable coating, low-temperature lubricant option | Corrosion system, shock review, documented lubricant interval |

Our quotation pack can include tooth bearing checks, ratio confirmation and lubricant notes so engineers see the load path before procurement releases a purchase order. The goal is traceable duty fit, not a generic reducer substitution.

Low rpm, wind stow events and daily reversal cycles are reviewed against holding torque, shaft orientation and seal package. We document the duty cycle so the gearbox is not oversized by habit or underspecified by catalog guesswork.

Cone Drive gearbox repair requests are screened for wear mode, lubrication condition, bearing L10 assumptions and shaft alignment. The response can separate quick spares from redesign cases that need a service factor review.
