Internal Planetary Gear Kit

Precision Pinion Internal Gear Ring for Planetary Gear

Categories: ,


Internal planetary gear kit is also known as Planetary gear sets. Planetary gear sets possess numerous advantages over their parallel-axis counterparts in terms of their power density, tolerance insensitivity, noise attributes, and kinematic flexibility. One potential disadvantage of planetary gear sets is power losses due to multiple-planet branches, resulting from an increased number of gear meshes and bearings.

A simple planetary gear mechanism is usually called a three-member mechanism, and the three members are the sun gear, the planet carrier, and the ring gear. Suppose these three components need to determine the relationship between each other. In that case, generally, one of the components needs to be fixed first, then decide who the active part is and determine the active region’s speed and rotation direction.


The planetary gear has the following characteristics in structure:

1, The sun gear, planet carrier, and ring gear are all concentric. That is, they rotate about a common axis. This can eliminate countershafts and intermediate bags used in manual transmissions.

2, All gears always mesh with each other. No gear sliding is required when shifting gears, so friction and wear are short and long life.

3, Simple and compact structure, its load is distributed to many teeth, and its strength is high.

4, Multiple transmission ratios available.
