Robot Speed Reducer Planet Gear
Product Description
The Robot Speed Reducer Planet Gear is a critical component within robotic gearboxes, responsible for splitting heavy loads and delivering high torque multiplication. Operating under continuous contact stress, each Robot Speed Reducer Planet Gear must exhibit excellent fatigue resistance and operate with minimal backlash. We machine these planet gears from high-purity alloy steels, utilizing precise CNC gear shaping and tooth flank grinding to achieve DIN 5 profile tolerances. The internal bore of each Robot Speed Reducer Planet Gear is ground to an ultra-precise H6/H7 tolerance (within 4 microns) to ensure a perfect fit with needle roller bearings, eliminating radial play.
For B2B buyers and gear assembly distributors, sourcing a Robot Speed Reducer Planet Gear with consistent geometric tolerances is key to reducing assembly times and field wear. We utilize precise flank crowning to optimize the tooth contact pattern of the Robot Speed Reducer Planet Gear, significantly reducing friction, thermal buildup, and operational noise. Backed by our elite, academician-led R&D center, we continually refine our heat treatment and surface finishing technologies, enabling our Robot Speed Reducer Planet Gear to deliver double the fatigue life of standard commercial-grade gears.

FAQ
Can you grind the internal bore to act directly as a needle bearing raceway?
Yes, we can grind the internal bore to a surface finish of Ra 0.2μm and a hardness of HRC 60-62, allowing it to serve directly as a high-precision bearing outer raceway.
What is the minimum module gear you can grind with DIN 5 accuracy?
Our CNC gear grinders can grind planet gears with modules as small as 0.3 Module.
How do you ensure matching gear thickness across a set of planet gears?
We grind the width of each gear in the same batch to a tolerance of within ±0.005mm, ensuring equal axial clearance and balanced load distribution in your planet carrier.
