The article provides information on planetary gearheads which are high-precision, motion control devices. The functions of several specific types of planetary gearheads are discussed. The benefits of planetary units with larger contact ratio, due to their helical gears, are detailed. The importance of choosing the right gearhead and accurately sizing it is also explained.
