Various Planetary Gearbox and Platform Set The planetary gearbox set is a series of various types of reducers based on planetary gearboxes that are commonly used. Our company primarily manufactures the following types within this series: planetary gearboxes,spiral bevel gearbox, and hollow rotary platforms.Planetary gearboxes are the standard basic type. Spiral bevel gearboxs and hollow rotary platforms can integrate standard planetary gearboxes, thus enriching their types and offering greater torque and a wider range of reduction ratios. These three common types of reducers are typically used in application fields such as precision machine tools, medical equipment, packaging equipment, logistics equipment, automation equipment, and 3C equipment.
