whatisgearbox2Nowadays planetary gearboxes are broadly used on diverse industrial machines for high efficiency and stability (see "Advantage of Planetary Gearbox").   Before involving in deeper level of applying we need to know the mechanical element and construct inside the planetary gearbox.

aboutgearrackA rack and pinion (wheel gear) is a type of linear actuator that comprises a pair of gears which convert rotational motion into linear motion (reciprocating motion).  A circular gear called “Pinion”, and the engaged teeth on a linear gear bar called “Rack”.  Rotational motion applied to the pinion causes the rack to move, thereby, translating the rotational motion of the pinion into the linear motion of the rack.

DSC 9138sHow to select a proper Planetary Gearbox for meeting specific application requirements, following factors need to be considered.

moduleCaculation1Module is the unit of size to indicate how big or small a gear pinion is.  It is the ratio of the reference diameter of the gear pinion divided by the number of teeth.  Thus the formula of module calculation is as following.

ToqueCalculationThe lifetime of a planetary gearbox depends on calculation of required torque, also needs to be considered the peak torque happened in accelerating or decelerating should be less than the maximum load torque of a planetary gearbox.

GearTerminologyFor using or designing mechanism by gear rack system, it is necessary to have terminology knowledge of gear rack as mechanical element.
