TIANYI High-Precision Helical Planetary Gearboxes

MANUFACTURER DOCUMENTATION

Overview

Tianyi’s high-precision planetary page describes helical planet and sun gears, an integrated carrier/output shaft and a clamping input connection. The catalog identifies SCM415/420 alloy steel and DIN6 gear accuracy. Its stated efficiency exceeds 97% for one stage and 94% for two stages. The family introduction advertises standard and customized backlash levels, but individual selector entries vary; the ordered frame and precision grade must therefore be checked explicitly. Use the official motor interface and rating sheet to establish torque, input speed and allowable bearing loads rather than applying a headline precision value to every size. The manufacturer image illustrates the TB variant within this family.

Model configuration table

The source page provides a series overview rather than a complete model/ratio rating table. Use the manufacturer link above for selection drawings and confirm the precise operating point before ordering.

Before you specify this gearbox

A planetary gearbox shares load across several planet gears. Confirm nominal and peak torque separately, together with ratio, input speed, backlash and mounting dimensions.

Confirm continuous, peak and emergency-stop load limits separately.
Match the motor flange, shaft, mounting orientation and lubrication requirements.
Request the current drawing revision and selection calculation from the manufacturer.
