AGMA 06FTM04 - Precision Planetary Servo Gearheads
October 1, 2006 - AGMA

Automated machines use servomotors to perform complex motions. Planetary gearheads are frequently used in conjunction with servomotors to match the inertias, lower the speed, boost the torque, and at the same time provide a mechanical interface for pulleys, cams, drums and other mechanical...

SAE J646 - (R) Planetary Gears - Terminology
July 1, 2018 - SAE

Figures 1 through 5 illustrate in simplified form some of the more common planetary gear arrangements in order to establish applicable terminology. Figures 6 and 7 provide additional examples that use elements of those gear arrangements. Gear ratio is the numerical ratio...

Planetary Geodesy and Remote Sensing
October 22, 2014 - CRC

Although lunar exploration began in the 1960s, the moon and other planets have many long-standing, unanswered questions about planetary environments, origin, formation and evolution, magnetization of crustal rocks, internal structure, and possible life. However, with the recent development...

An Introduction to Planetary Atmospheres
September 7, 2010 - CRC

Planetary atmospheres is a relatively new, interdisciplinary subject that incorporates various areas of the physical and chemical sciences, including geophysics, geophysical fluid dynamics, atmospheric science, astronomy, and astrophysics. Providing a much-needed resource for this...

Gears and Gear Drives
January 1, 2012 - WILEY

Understanding how gears are formed and how they interact or mesh with each other is essential when designing equipment that uses gears or gear trains. The way in which gear teeth are formed and how they mesh is determined by their geometry and kinematics, which is the...
