Also known as reverse gear systems, reverse drive units, or slewing drives, the reverse drive pair is widely used in various industries such as aerospace, tower cranes, excavators, construction machinery, satellite receiving systems, and solar energy applications. Recently, its use in solar photovoltaic power generation has increased significantly due to its efficiency and reliability. The specification types of the reverse drive pair vary depending on the approximate raceway diameter of the bearing. Common international designations include WD-080, WD-0130, WD-0170, WD-0223, WD-0343, WD-0419, WD-0478, WD-0625, and others. In China, domestic models are typically named based on the approximate raceway diameter in inches (1 inch = 25.4 mm), such as SE3, SE5, SE7, SE9, SE12, SE14, SE17, SE21, and SE25. The "WD" in foreign designations stands for "Worm Drive," while "SE" in domestic designations refers to "Slewing Enclosure." In the solar industry, there is no universal standard for classifying the types of reverse drive pairs used. Most applications are determined by the area of the solar panels. For example: - SE3: 3–5 m² - SE5: 6–9 m² - SE7: 10–17 m² - SE9: 18–30 m² - SE12: 31–45 m² - SE14: 46–60 m² - SE17: 61–95 m² - SE21: 96–120 m² - SE25: 120–160 m² These are general guidelines and may vary depending on specific system requirements. The main components of a reverse drive pair include the reverse bearing, worm gear, cast base, and standard parts such as bearings and bolts. In solar power generation, it is often paired with a DC planetary gear motor or a speed-reduced motor. In construction machinery, hydraulic motors are commonly used as the driving system.
