TIANYI TYK / TNK Standard Spur Planetary Gearboxes

MANUFACTURER DOCUMENTATION

Overview

The TYK page covers Tianyi’s standard spur planetary family, alongside TNK and TYKH designations. It describes a full-complement needle-bearing arrangement and an integrated planet carrier and output shaft. Published family efficiency exceeds 96% for one stage and 92% for two stages. The page’s introductory backlash claim differs from some selector options, so no single precision value is applied to every frame here. Confirm the exact code and grade before using backlash in a positioning calculation. The public page does not provide a complete rated torque matrix; request that table together with the motor-adapter and output-shaft drawing.

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.
