Product Introduction

GMD series rotary slewing reducer is a professional integrated transmission unit independently developed by GUOMAO specially for photovoltaic solar tracking systems. It integrates worm gear assembly, heavy-duty slewing bearing and drive motor into one compact unit, serving as the core rotation drive for single-axis and dual-axis PV trackers. With built-in self-locking function, ultra-high outdoor environmental resistance and precise low-speed positioning performance, it can keep solar panels aligned with sunlight stably all day long to maximize power generation efficiency.

Core Advantages

1. Reliable worm self-locking structure: Effectively prevents reverse rotation of PV brackets under strong wind, no extra brake required for stable positioning.
2. Outstanding outdoor adaptability: Full IP66 fully sealed housing with anti-corrosion and salt-spray resistant coating, stable operation under -40℃ to +75℃, dustproof, rainproof and anti-aging for long-term outdoor exposure.
3. Integrated compact layout: All-in-one integrated design saves installation space, simplifies on-site assembly and wiring work for power station construction.
4. High precision tracking control: Fine segmented reduction ratios, ultra-low backlash, positioning accuracy up to ±0.05°, ensures continuous accurate sunlight capture.
5. Super heavy load capacity: Large-size integrated slewing bearing bears large radial load, axial load and overturning moment, resistant to wind impact and long-cycle alternating loads.
6. Low maintenance cost: Long-life special lubricating grease chamber with extended refueling interval; wear-resistant alloy worm wheel & worm gear with service life over 20 years.
7. Flexible drive matching: Compatible with 24V/48V DC brushless motors and AC servo motors, perfectly matched with mainstream PV tracking controllers worldwide.

Application Scenarios

1. Large ground-mounted single-axis & dual-axis photovoltaic power stations
2. Concentrated solar power (CSP) thermal tracking equipment
3. Distributed rooftop solar PV tracking brackets
4. Agrivoltaic complementary solar tracking systems
5. Auxiliary rotary equipment: monitoring turntables, small outdoor rotary platforms, light-duty engineering slewing devices
