An epicyclic gear train is a gear system consisting of one or more outer gears, or planet gears, revolving about a central, or sun gear. Typically, the planet gears are mounted on a movable arm or carrier, which itself may rotate relative to the sun gear. Epicyclic gear trains are widely used in industry and transportation, including automobiles and bicycles, as well as many other machines.


The epicyclic gear train was invented by the Greek mathematician Apollonius of Perga in the 3rd century BC, who used it to model the motions of the planets. However, it was not until the 16th century that the first practical use of the epicyclic gear train was made, in a clock designed by the Swiss mathematician Jost B¨¹rgi.


The design of an epicyclic gear train is based on the interaction of three basic elements: the sun gear, the planet gears, and the ring gear. The sun gear is positioned at the center of the system and is surrounded by the planet gears. The ring gear is positioned outside the planet gears and meshes with them.


  • High gear ratios can be achieved in a small space.
  • Smooth and quiet operation due to the even distribution of load.
  • Efficient power transmission due to reduced friction.
  • Can be used as a speed reducer or a speed increaser.

Six Sigma

Six Sigma is a methodology for process improvement that seeks to eliminate defects and reduce variability in manufacturing and service processes. It is based on statistical analysis of data and focuses on improving the quality of output by identifying and removing the causes of defects.
