Product Introduction
Pinion planetary gear, precision planetary gearbox, is a high-precision industrial planetary gearbox. Driven by a finely machined small sun pinion gear meshing with multiple planet gears, this pinion planetary gear has strictly controlled tooth tolerance after precision grinding. It features high positioning accuracy, smooth transmission and low backlash. Widely adopted in servo robots, inspection instruments, vision sorting systems and CNC tables requiring precise point positioning.
Product Characteristics
Precision ground small module sun pinion
The pinion planetary gear uses precision ground small module sun pinion with high gear accuracy and minimal meshing fluctuation. This industrial planetary gearbox delivers stable low-backlash output.
Multi-point load-sharing planet gear set
The pinion planetary gear is equipped with multi-point synchronous load-sharing planet set. Multiple planet gears evenly share power from the sun pinion to reduce local tooth pressure and wear, keeping consistent precision over long service time.
Preloaded precision bearing unit
The pinion planetary gear is fitted with preloaded precision bearing unit to remove bearing clearance and suppress axial play under high-speed reciprocating motion, stabilizing gear meshing position.
Product advantages
Ultra-low transmission backlash for accurate positioning control
The precision gear pair of pinion planetary gear achieves ultra-low backlash and small reverse hysteresis, meeting strict repeated positioning requirements of precision machinery.
Low transmission ripple and smooth jitter-free motion
High-precision sun pinion together with planet gear set reduces meshing ripple. It runs smoothly during high-speed reciprocating movement without jitter that may affect measurement accuracy.
Excellent long-term precision retention and less recalibration
The load-balanced structure of pinion planetary gear slows gear wear. Backlash increases slightly over years, so precision machines require fewer stops for recalibration.

FAQ
Q: What is the standard backlash range of pinion planetary gear?
A: Standard pinion planetary gear has backlash ≤5 arcmin, ultra-precision version can reach ≤1 arcmin. Models can be selected according to positioning requirements of precision machines.
Q: Is pinion planetary gear suitable for high-frequency reciprocating motion?
A: Yes. Designed with precision pinion gear and preloaded bearings, pinion planetary gear withstands frequent forward and reverse reciprocation. It is a preferred industrial planetary gearbox for inspection and robotic equipment.
Q: What grinding process is applied for gears of pinion planetary gear?
A: Both sun pinion and planet gears of pinion planetary gear are form ground with low tooth surface roughness, ensuring smooth meshing and stable precision.
Q: Can pinion planetary gear be directly coupled to servo motors?
A: Yes. The pinion planetary gear adopts standard servo mounting flange and directly fits mainstream servo motors without extra adapter plate.
Q: What temperature rise is allowed during operation of pinion planetary gear?
A: Under rated working condition, temperature rise of pinion planetary gear is limited within 35℃. Low temperature rise protects precision gear pair and prevents precision drift caused by heat.
