Overview

Compact two-stage RV reducer with an integrated main bearing and a wide choice of ratios. The industry-standard joint reducer for 6-axis industrial robots.

A spur first stage drives crankshafts that orbit two cycloid discs against a ring of pins. Many teeth share the load, so the reducer is very stiff and takes shock well, and the main bearing carries the tilting moment of the joint directly.

Typical uses: industrial robot base, shoulder and elbow joints, welding and painting positioners, machine-tool rotary tables and ATCs, heavy indexing tables and turntables.

Ordering

Order code TRV-80E-XX, where XX is the ratio (for example TRV-80E-81). Price ₹1,27,020 per unit, ex-works Rajkot, excluding GST and freight, the same for every ratio. MOQ 1 piece; ask for volume pricing from 10 pieces. Send your motor model and we confirm the input gear or adapter flange you need.

Ratings are typical values from manufacturer tests and are for guidance only. Real performance depends on installation, load, lubrication and environment; confirm your selection with Torqtron engineering. The photograph is representative of the series.

Questions about the TRV-80E

Is the price the same for every ratio?

The TRV-80E costs ₹1,27,020 per unit, ex-works Rajkot, excluding GST and freight, for any listed ratio. MOQ is 1 piece; ask for volume pricing from 10 pieces.

Why are there two ratios for each size?

The listed ratio applies when the case is fixed and the shaft (carrier) is the output. If the shaft is fixed and the case rotates, the ratio is one less, for example 121:1 becomes 120:1, and the case turns in the same direction as the input gear.

Which motor can drive the TRV-80E?

Send us the motor model, flange and shaft size. We machine the input gear and, if needed, an adapter flange so the motor bolts straight on.
