TST Precision Planetary Gear Reducer

MANUFACTURER DOCUMENTATION

Overview

The TST is TECHMECH’s right-angle precision planetary series. The official product page identifies output sizes from 75 to 240 mm and lists direct ratios of 1, 2, 3, 4 and 5. A separate gear-reducer combination can extend the reduction to 500:1; that figure describes the combined arrangement, not every single TST unit. The maker describes precision-ground gearing, multiple machined mounting surfaces and installation in any orientation. Choose the output frame and combined or direct drive layout before checking backlash, service life and lubrication details in the current catalogue. A model drawing is needed for shaft and flange fit.

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.
