A planetary gearbox refers to a gear system in which one or more "planet" gears rotate around a central "sun" gear.  Typically, a planet carrier is driven by the input torque which rotates the planets around a fixed outer ring (sometimes referred to as the annulus).

A gearbox provides speed and torque conversions from a rotating power source to another device using gear ratios.  It can be used in various power sources to another device using gear ratios.  It can be used in various situations such as precise machine tools, and anywhere else mechanical equipment.  PHT Vertex Precision offers high-valued in-line planetary gearboxes which are high-quality planetary gearboxes, designed to offer you the precision and performance you need.

There’re eight ( 8 ) models can be chose for diverse fields of motion control applications.  The choices let you select the appropriated backlash option for your application.  Precision backlash is as low as 1 arc min maximum.  We stock many ratios to match up to our wide range customers in worldwide market, and make a gearbox to fit any motor in as little as 7-10 working days or earlier. Ratios are available from 1:3 to 1:1000 with torque rating up to 10,4 88 in-lbs. ( 167,808 oz.-in ).
