Planetary Gears
Planetary gears are a type of gear system that consists of a central sun gear, several planet gears that orbit around the sun gear, and an outer ring gear that meshes with the planet gears. Planetary gears have several advantages, such as high torque capacity, compact size, high efficiency, and multiple speed ratios. Planetary gears are widely used in various industries, such as automotive, aerospace, robotics, and appliances. To manufacture planetary gears, different processes and machines are required for each component. The sun gear and the ring gear are usually made by hobbing or shaping, while the planet gears are made by hobbing, shaping, or broaching. The carrier that holds the planet gears can be made by casting, forging, or machining. The final assembly of the planetary gear system involves aligning and securing the components with pins, bolts, or rivets.
